AutoTurn — Matching Engine Reference

Overview

The Matching Engine

The matching engine is the brain of AutoTurn. It runs continuously against the open request pool — the live collection of all pending trade requests from active members. Its job is to find groups of 2, 3, or 4 members whose cars, tokens, windows, and locations are mutually compatible, and surface those groups as confirmed trade proposals.

Technically, it is a directed graph cycle detection algorithm. Each open request is a node. A directed edge A→B is drawn when member A can receive member B's car — meaning tier match, token budget, window overlap, and same hub all pass. A valid trade is any cycle in that graph.

Pipeline — What Runs Each Cycle

Input

Load the Open Request Pool

All trade requests with status open are loaded. Matched, expired, or cancelled requests are excluded. This is the active working pool for the current run.

O(1) — direct DB query

Graph Construction

Build the Directed Compatibility Graph

Every pair (A, B) is checked: can A receive B's car? If yes, draw edge A→B. Five checks run per pair: same hub, tier in desired range, window overlap, sufficient token balance, within token budget. This produces an adjacency list used in all subsequent steps.

O(n²) — at 500 requests: 250,000 comparisons

Cycle Detection — Pass 1

Find All 2-Way Matches

Scan for symmetric edges: A→B and B→A both exist. These are direct swaps — each member gets the other's car. Simplest trade, lowest coordination overhead, preferred when score is equal to a more complex option.

O(n²)

Cycle Detection — Pass 2

Find All 3-Way Matches

For each edge A→B, walk B's neighbors looking for a path back to A through a third member C. A→B→C→A. Each member moves one step forward in the ring; token settlement flows around the cycle accordingly.

O(n × d²) where d = avg out-degree

Cycle Detection — Pass 3

Find All 4-Way Matches

Extend one more hop: A→B→C→D→A. Four members, four cars, four token settlements. The algorithm ensures no member appears twice in the same cycle. 4-way trades are maximally efficient for AT (4 platform fees collected), but require the most coordination to confirm.

O(n × d³) — fast at real pool sizes

Ranking

Score and Sort All Candidates

Every candidate cycle receives a quality score based on how well each member's received car matches their desired tier range, plus a small bonus for low token gaps and a small penalty for more complex trades. All candidates are sorted descending by score before assignment.

Higher score = better quality match

Assignment

Greedy Assignment — No Double-Booking

Starting from the highest score, each candidate cycle is accepted if all its members are still unassigned. Accepted members are locked. Lower-scored cycles that share any member with an already-accepted trade are skipped. This guarantees no member is double-booked.

Greedy — optimal for small pools

Near-Match Surfacing

Surface Best Option for Unmatched Members

Any member with no confirmed match gets an immediate near-match suggestion: the algorithm relaxes their tier range by 1–2 tiers and searches for the closest available 2-way trade. The member sees the offer with full cost breakdown and can accept, stay in the pool, or cancel. No forced wait.

Tier range relaxed ±1, then ±2

Output

Confirm, Settle, Activate

Confirmed matches are presented to all members for final confirmation. Once all parties accept: tokens are collected, insurance activates, handoff details are sent, and requests are closed. If any member declines or times out, the remaining members are returned to the pool.

All-or-nothing confirmation

Edge Conditions — When A Can Receive B's Car

All five conditions must pass simultaneously. A single failure means no edge is drawn — that pair cannot be in the same trade.

Check 01

Same Hub

Both members must be assigned to the same AT garage location. Houston members only match with Houston. Dallas only with Dallas. No cross-city trades — ever. Hub is set at enrollment and only changes with a formal transfer request.

A.hub_id == B.hub_id

Check 02

Tier Match

B's vehicle tier must fall within A's desired tier range. If A wants T5–T7 and B has a T4, no edge. If A wants T5–T7 and B has a T6, edge is drawn.

A.desired_min ≤ B.vehicle_tier ≤ A.desired_max

Check 03

Window Overlap

A's preferred window and B's preferred window must share at least one day. A weekday-only member and a weekend-only member cannot trade. "Any" members are compatible with all windows.

days(A.window) ∩ days(B.window) ≠ ∅

Check 04

Token Balance

A must actually hold enough tokens to cover the full cost: platform fee (1) + tier gap (if upgrading) + window surcharge + surge. This is checked against their real balance, not their budget preference.

A.token_balance ≥ total_cost

Check 05

Token Budget

A must be willing to spend the required tokens on this trade, per their stated budget for this request. A member might have 20 tokens but only want to spend 6 on a given trade — that request's budget governs.

A.token_budget ≥ total_cost

Token Cost Formula

Total Cost Breakdown

Every cost component adds up before the check passes. Gap is 0 when receiving same or lower tier (downgrading earns tokens instead). Surge is 0 when demand is normal.

cost = 1 + max(0, B.tier−A.tier) + window_fee + surge

Trade Types — 2, 3, and 4-Way Cycles

2-Way

Direct Swap

A (T4) ⇄ B (T6)

A pays B: 2 gap tokens
B pays A: 0 gap tokens
AT earns: 2 platform fees

The simplest trade. Two members swap cars directly. Each pays a platform fee to AT; the upgrading member pays gap tokens to the member whose car they're receiving.

Complexity: O(n²) · Priority: highest

3-Way

Circular Chain

A (T5) → B (T3) → C (T7) → A

A pays C: 2 gap tokens
B pays A: 2 gap tokens
C earns: 4 gap tokens
AT earns: 3 platform fees

Three members form a ring. Each receives the car of the next member in the chain. Token settlement flows around the ring — members trading up pay; members trading down earn.

Complexity: O(n×d²) · Priority: second

4-Way

Full Ring

A → B → C → D → A

Each member receives
the next member's car.
AT earns: 4 platform fees

Four-member rotation ring. Maximum complexity for members but maximally efficient for AT's token economy. Used when no 2-way or 3-way match exists for all parties at the required quality threshold.

Complexity: O(n×d³) · Priority: third

Scoring System

Every candidate cycle is scored before assignment. Scores determine which match gets priority when members appear in multiple candidate cycles. Higher score always wins.

Condition	Score	Description
Received tier is within desired range	+100 / member	Perfect match — member gets exactly what they asked for
Received tier is 1 outside desired range	+60 / member	Near match — one tier off from the boundary of their request
Received tier is 2 outside desired range	+20 / member	Suggested match — two tiers off; still surfaced but lower priority
Received tier is 3+ outside desired range	−30 / member	Poor fit — penalized but not discarded if it's the only option
Gap tokens ≤ 2 for this member	+10 / member	Bonus for low economic friction — trade doesn't drain token balance heavily
Each additional member beyond 2	−5 / member	Slight penalty for complexity — prefer 2-way over 3-way when scores are close

Token Settlement — Worked Example

3-way trade on an extended weekend with surge level 1 active. Member A (T5) receives C's T7 car, B (T3) receives A's T5 car, C (T7) receives B's T3 car.

3-Way · Extended Weekend · Surge +1

Member A — gives T5, receives T7

Platform fee: 1 · Gap paid to C: 2 · Window: 3 · Surge: 1 · Gap earned: 0

−7 tokens

Member B — gives T3, receives T5

Platform fee: 1 · Gap paid to A: 2 · Window: 3 · Surge: 1 · Gap earned: 0

−7 tokens

Member C — gives T7, receives T3

Platform fee: 1 · Gap paid: 0 · Window: 3 · Surge: 1 · Gap earned from A: 2 + from B: 2

−1 token

AT earns: 3 platform fees + 3×window + 3×surge = 3 + 9 + 3 = 15 tokens this trade

Hub Constraint — Geographic Scoping

Why It Exists

No cross-city trades

AutoTurn's handoff model requires members to exchange keys at an AT-designated garage or partner location. A Houston member and a Dallas member cannot share a handoff location — so the algorithm never draws an edge between them, no matter how well their tiers and tokens align.

Hub is assigned at enrollment based on the member's primary city. It is stored on every trade request and is the first check in the edge condition — fail here and no further evaluation happens.

Multi-Hub Future

When a city gets multiple garages

Once a city like Houston has two AT locations (e.g., Galleria + Heights), the algorithm can be extended to match members at adjacent hubs within a defined radius — e.g., 30 miles. The member is assigned to their nearest hub at enrollment; cross-hub matching is only enabled when the hubs share a service area.

Launch configuration: 1 hub per city, same hub = only match. No radius logic needed until multi-hub density is reached.

Performance Characteristics

The algorithm is designed to run comfortably at all realistic pool sizes. Performance only becomes a consideration above ~2,000 simultaneous open requests per hub — a scale that requires hundreds of active members per city.

AutoTurn — CEO Ideas

Priority 1 — Must Fix Before Launch

Critical Pre-Launch Items

These five items are existential. AutoTurn cannot take its first trade without them. Each one prevents a category of failure that cannot be corrected after the fact.

Liquidity Threshold Rule

Do not activate dues for a tier until at least 3 cars exist at that tier in the pool. Without this, premium members have nothing to drive → they churn → pool shrinks → death spiral. Consider AT leasing 2–3 vehicles in T6–T8 as pool stabilizers at launch. Founding members who join early don't pay full dues until their tier hits minimum coverage.

ExistentialOperations

Digital Inspection Report

Every handoff needs a timestamped, photo-documented, digitally signed inspection report stored in the member's account permanently. Minimum 40 geotagged photos per pickup and return. Use an off-the-shelf inspection app (DamageSketch, DriveOffLot). Without this, damage disputes are unwinnable. Build before the first trade — not after.

ExistentialBuild First

Dispute Resolution Framework

Write and publish a formal dispute resolution policy before the first car changes hands. Must cover: who adjudicates, what evidence is required, timeline, and possible outcomes. Existence of a clear framework prevents most disputes from escalating and sets legal defensibility from day one.

ExistentialLegal

Pause Policy

Members need a formal pause option: 1× per year, up to 60 days, at ~25% of monthly dues. Without this, members who travel or have a maintenance issue churn permanently instead of temporarily. A pause costs AT almost nothing. Losing a member costs months of CAC recovery.

ExistentialOperations

"What Happens If…" Guide

Plain-language member guide covering every failure scenario: accident, mechanical failure, theft, late return. Who to call, what to do, what they're liable for. Must exist before the first trade. Members who feel uncertain about edge cases don't trade — they just churn at renewal.

ExistentialOperations

Retention & Satisfaction

Member Experience Features

High perceived value features that drive retention and satisfaction without requiring major infrastructure. Build these after core ops are stable.

Vehicle Tracking Integration

Real-time GPS tracking for owners to see where their car is during a trade. Integrate with Bouncie, Optimus, or OEM telematics (BMW ConnectedDrive, Ferrari Remote, Porsche Connect). Table stakes for T7+ members — a $300K car owner will not trade without knowing where their vehicle is.

Build NextOperations

Car Wishlist / Preference Profile

Members set preferences (convertible, manual transmission, color, vehicle type) that influence but don't override the matching algorithm. Cheap to build, high perceived value. Improves match satisfaction scores. Members who feel the platform "knows them" retain longer.

Build Next

Extension Policy

Publish a formal trade extension system — member pays a token cost to extend their window; AT checks whether the next member in queue needs the car. Must exist before the first extension request, not as a reactive decision. Unmanaged extensions create scheduling conflicts across the entire pool.

OperationsPolicy

Tier Upgrade Concierge Program

AT actively helps members sell their current vehicle and source a higher-tier replacement. AT charges a sourcing/consignment fee. Gamify the upgrade path. This organically upgrades pool quality over time — more T7+ cars, fewer T1–T2 cars — which improves the platform for every member at the top.

RevenuePhase 2

New Income Vectors

Revenue Stream Ideas

Eight revenue opportunities beyond the core membership model. Most require Phase 2+ infrastructure. Prioritize by margin and operational overhead.

OEM / Manufacturer Partnerships

Ferrari, Porsche, Lamborghini pay AT to place 1–2 demo vehicles per market in the pool. Members get first-access to new models. AT earns a brand partnership fee plus per-drive activation. AutoTurn's member base is the exact target buyer for these brands — this is a perfect mutual value proposition.

RevenuePhase 3

Dealer Consignment Program

Member wants to sell their vehicle → list it as "on rotation" while AT surfaces it to other members who've already driven it. AT charges a 1–2% facilitation fee. Zero-friction used car marketplace for exotics. Members have already vetted the car through driving it — conversion rate should be exceptional.

RevenuePhase 2

Aftermarket / Modification Referrals

PPF, custom wraps, carbon fiber upgrades — AT-preferred vendors pay referral fees. Members trust AT's recommendations because AT has already vetted their car. Attach referral program to the post-inspection report: "Your car is in great shape — here are our partners for protecting it further."

RevenuePhase 2

Discovery Plan (No Vehicle Required)

$199–$499/month. No vehicle contribution required. 1–2 drives per year from AT's seeded fleet. Converts fence-sitters who don't trust the platform yet. Also a direct acquisition funnel → full membership once they've experienced it. Doubles as the on-ramp to the Rental Access Program.

RevenueBuild Early

Corporate / Concierge Membership

Family offices and UHNW individuals contribute a vehicle (or AT sources one), assign a driver/assistant as operator, receive quarterly utilization reports. Priced at 2–3× standard for same band. Minimal extra operational overhead — the car is already in the pool, the member just has a different profile.

RevenuePhase 2

Member Events / Track Days

Closed member events: track days, concours dinners. $500–$2,500/ticket. Direct revenue + social proof content + press + retention. Founding members feel like they're in something exclusive. AT owns the relationships and venue partnerships. This is brand-building with a margin.

RevenuePhase 2

Security Deposit Float — Yield

$10K–$25K deposits per T9–T10 member. At 50 members = $500K–$1.25M sitting idle. Place in short-duration T-bills or HYSA. ~$25K–$60K/year passive income at current rates. Start collecting the deposits on day one regardless — the yield is the bonus; the deposits are table stakes for T9–T10.

RevenueFinance

Data / Valuation Intelligence (Long-Term)

AT will accumulate real-world condition, mileage, and usage data on hundreds of exotic vehicles. Potential buyers: insurance underwriters, auction houses, wealth managers. Start collecting data with the right schema now — retrofitting a database is expensive. The data business is a Phase 4+ story, but the collection starts on day one.

Launch & Acquisition Strategy

Go-To-Market Ideas

The founding cohort strategy. AutoTurn's launch is not a marketing campaign — it's a personal recruiting operation targeting 5–10 connectors per city.

The Right Founding Member Archetype

NOT the richest car owner. The most connected car owner. Active in at least one car community (Cars & Coffee organizer, track day regular, club member). Owns a T5–T8 vehicle. Has disposable income but understands the cost-of-ownership argument immediately. Socially credible — when they talk, other serious car people listen.

GTM

Launch in 2 Cities First

Miami and Dallas (or Houston). Dense exotic car culture, social communities already exist. Do not try to be in three cities at once. Nail the operational playbook in two cities before geographic expansion. Houston has money and density; Miami has tourism volume and existing luxury culture.

GTM

Find the 5 Connectors Per City

3–5 people per city who are known operators in the car community. Not influencers — organizers. The Cars & Coffee host. The regional Porsche club officer. The guy every exotic owner in town follows on Instagram because he's actually in the scene. Approach with a personal founding member invitation — not a form.

GTM

Founding Member Offer (Structurally Different)

Founding members get: locked founding rate for life (or 5 years), 2× token bonus for first 6 months, "Founding Member" badge and recognition in platform, and a private event invitation (track day or dinner) where they sign up in the room. The offer closes when the cohort is full — create real scarcity.

GTMRevenue

Activate the Waitlist Now

Tag every current waitlist signup by: city, tier band interest, how they heard about AT. This is the founding member recruiting list, sitting unused. Segment it and personally reach out to the highest-tier signups in your launch cities. Every week you wait is another week a connector forgets they signed up.

Do NowGTM

Moat & Exit Strategy

Defensibility Ideas

Three structural moves that make AutoTurn harder to copy, harder to regulate away, and more valuable to a potential acquirer.

Legal Opinion on Non-Rental Status

Get a formal legal opinion in the first 3 operating states confirming AT is not a rental company. Different licensing, insurance mandates, and tax treatment apply to rentals vs. member exchanges. This opinion becomes a competitive document — the reason AT can operate where others cannot. File it before the first trade in each state.

LegalPre-Launch

Waitlist Segmentation (Do This Now)

Tag every current waitlist signup by: city, tier band interest, how they heard about AT. This data is the founding member recruiting list, sitting unused. Act on it before launch. A tagged, segmented waitlist is a fundable asset — it proves market interest by geography and tier without requiring a live product.

Do NowGTM

Think About the Exit

Likely acquirers: luxury automotive group (Penske, AutoNation), lifestyle membership platform (Wheels Up model), or fintech/alternative asset platform (exotic cars as asset class). Worth deciding internally which direction to optimize for — it changes which metrics matter most. Revenue per member? Geographic density? Fleet data? Decide now, not in year 3.

StrategyLong-Term

New Revenue Layer — CEO Session April 2026

Rental Access Program (RAP)

A cash-based vehicle access layer, separate from the rotation model, positioned as the on-ramp to full membership. Ring-fenced legally and operationally. RAP is not a rental company add-on — it's a funnel and a fleet utilization engine.

AT-Owned Fleet — T5 to T7 Only

Launch with 2–3 AT-owned vehicles in the T5–T7 range (Porsche 911, Ferrari Roma, Lamborghini Urus, McLaren 570S). Single hub location in Houston. T1–T3 is too low-margin and dilutes the brand. T8–T10 creates catastrophic insurance exposure with unknown renters. Lease or finance — don't buy outright with cash at MVP.

Phase 1Operations

Cash-Only Pricing — No Tokens

Renters pay dollars, not tokens. Tokens are a membership benefit — mixing them into rental dilutes the value proposition. Rack rates: T5 $650/day · T6 $950/day · T7 $1,400/day. Weekend rate 2.5× daily. Discovery Plan members get 20% off as a "rental credit" — but this is a discount mechanism, not a token transaction. Keep terminology clean.

RevenueFinance

Insurance: Separate Commercial Rental Policy Required

The existing 3-layer rotation stack does not cover cash rental transactions by non-members. RAP requires a separate commercial rental auto policy for the AT-owned fleet (Markel, AIG, Chubb — exotic rental specialists). Estimated $18K–$35K/year per vehicle. CDW product sold at booking ($100–$250/day). Get written broker confirmation before the first RAP transaction.

ExistentialLegal

Texas Rental Tax — 10% From Day One

Texas imposes a 10% state rental tax on motor vehicle rentals. The moment AT accepts cash for a vehicle rental, this applies. Must be collected and remitted from launch day — not retroactively after the fact. Get a Texas commercial/regulatory attorney to confirm tax treatment and licensing requirements before any transaction. Budget $2,000–$4,000 for the legal opinion.

LegalPre-Launch

Discovery → Membership Conversion Funnel

Every Class A renter who completes a rental gets an automated post-return email with a soft CTA to the Discovery Plan ($199–$499/month, 1–2 rental credits included). Discovery members who accumulate 3+ rentals get a conversion offer to full membership. Phase 2 option: Renters who complete 3+ rentals and convert get a 5-token bonus on membership activation — ties RAP into the token economy without muddying it.

RevenueBuild Early

Idle Fleet Program — Member Car Opt-In (Phase 2)

Members consent to AT renting their car when it's idle between trades. Member receives 60–70% of net rental revenue; AT takes 30–40%. Requires separate member consent agreement, confirmed commercial rental insurance, and explicit opt-in (never default). Do not launch at MVP — validate Source 1 (AT-owned fleet) first and prove the insurance structure is clean.

Phase 2LegalRevenue

Revenue Projection — Year 1 (3-Car Houston Fleet)

Gross rental + add-ons: ~$596K. Operating costs: ~$332K. Operating contribution: ~$263K pre-debt service. If fleet financed at 7%/48mo (~$16,800/mo): ~$60K net Year 1. Break-even utilization: ~38%. Key assumption: 55% average utilization ($850 blended daily rate). At 35% utilization (realistic Year 1): operating contribution drops to ~$48K.

RevenueFinance

3 Things To Do Before Spending a Dollar on RAP

1. Call the insurance broker — does current commercial master policy cover non-member cash rentals? Get it in writing. 2. Call a Texas commercial attorney — rental tax and licensing requirements. 3. Find 10 people in Houston who will verbally commit to renting a specific car at a specific price and date. If you can't find 10 in 2 weeks, demand signal is too weak for the capital required.
