Agentic commerce rails for automotive retail

Your agent builds the deal.
You show up for the keys.

PromisePath is the infrastructure beneath the first agent-to-agent car deals in America. Live inventory, firm out-the-door prices, real vehicle holds, finished paperwork, delivered to the dealership that finishes the deal. The excitement stays human. The friction does not survive the trip.

May 4, 2026 · History
The first agent-to-agent vehicle transaction in United States history.
Completed on the protocol that powers PromisePath. Announced at ASOTU CON by CarEdge.
In production
Live since April 2026.
Real quotes, real vehicle holds, real deal handoffs, and a complete audit trail, running daily at Mark Miller Subaru.
The network
Rooftop #1 is on the rails.
The network build is underway: one set of shared infrastructure, many dealerships, many manufacturers.
The complete car buying journey

Two moments belong to people.
Everything between them belongs to us.

Discovery
The customer finds the vehicle. The dream begins. This moment belongs entirely to the buyer and their imagination.
Not ours to own
PromisePath owns this
The frictionless middle
1
The agent reads real inventory
Live, freshness-stamped vehicles. No scraping, no guessing, no stale listings.
2
Firm out-the-door pricing
Itemized, with taxes and fees. Trade value and payments with labeled assumptions.
3
The vehicle is held
A real hold on a specific VIN, backed by verified commitment when it matters.
4
The deal lands on the dealer's desk
A nearly finished deal in the dealership's own CRM, not a name to chase.
Delivery
The customer arrives. The deal is already done. The only thing left is the handshake and the keys. This moment belongs to the human relationship.
Not ours to own

We do not touch the love.
We only remove the friction.

What runs on the rails

One integration. A whole deal.

Today, AI shopping agents reach dealerships through adversarial email. Nothing is tracked, nothing is attributed, and every deal is rebuilt from scratch. PromisePath replaces that chaos with rails any credentialed agent can transact on.

Search live inventory
Every record freshness-stamped. Agents know exactly what is on the ground and how current the answer is.
Firm out-the-door price
Itemized, with taxes and fees. No fabricated numbers anywhere on the rail. The AI reads tools, it never improvises a price.
Value the trade
Structured trade-in valuation and payment estimates, every assumption labeled so nobody negotiates in the dark.
Hold the vehicle
A real hold on a specific VIN. When commitment matters, verification happens on a secure first-party page. The rail never touches card numbers.
Deliver the deal
The nearly finished deal arrives in the dealer's existing CRM, in the lead format the store already consumes. Nothing about the process changes on day one.
Close the loop
Sales records match back to the conversation that produced them. Every attributed sale is visible to the dealer and reportable to the manufacturer.
Design
commitments
Itemized pricing, no fabricated numbers
Structured consent on every handoff
The audit trail is a first-class surface
The franchised dealer finishes every deal
The trust ladder

Access is earned the way car retail already earns it.

The industry's first hard gate has always been a card charge or a credit pull. PromisePath encodes that reality into four levels, so every agent transacts at exactly the depth it has earned.

L0
Anonymous
Any caller. Browse inventory, get prices, estimate trades and payments. No sign-up, rate-limited.
L1
Registered
Self-serve sign-up in minutes. Deliver deals to dealers and place short holds, with reputation tracked from day one.
L2
Verified
The shopper behind the agent steps forward: card-backed holds and financing pre-qualification on a secure first-party page.
L3
Contract
Signed agreements for OEMs and large partners. Bulk volume, negotiation, and program-level demand routing.
Who the path serves

One network. No landlord.

Multi-OEM from the root. Manufacturers route demand to their franchised dealers. Dealer groups administer. Rooftops transact. The platform, the data model, and the ledger stay neutral, and the dealer keeps the customer, the lead, and the sale.

For car buyers
Send your agent.
Keep your Saturday.
Your AI agent negotiates against real inventory and firm numbers, not templated replies. It holds the vehicle, finishes the paperwork, and hands the deal to the store. You show up once: for the keys.
Take the path
For dealers & OEMs
A channel you can finally see.
Agent traffic today looks like spam because it is invisible. On the rails, every agent is credentialed, every deal is attributed, and every closed sale traces back to the conversation that produced it. Programs get demand routing and channel analytics. No manufacturer is the landlord.
Put your rooftop on the rails
For investors & press
The rails are being laid now.
Agent-to-agent transactions moved from theory to production in 2026, and PromisePath was underneath the first one. The stores are real, the deals are real, and the first rooftop is already live. Early partners help define the standard every later agent builds against.

The public front door for AI agents: capability manifests, deal threads, self-serve onboarding, and the audit ledger that keeps the whole network observable and governable.
Take the path

The destination is the keys.
