Agentic commerce is online shopping done by software on a person’s behalf: an AI agent takes a request such as “find me a 65-inch TV under $800 with good reviews and buy it,” searches stores, compares options, and completes the checkout. The shopper never visits the merchant’s website. For that to work, merchants need a way to expose their catalog to agents, a way to accept payment from them, and a way to prove the shopper actually authorized the purchase.
This week gave the idea a concrete anchor: Firmly, a Seattle-area startup, closed a $15 million Series A to sell the merchant side of this plumbing, backed by the payment companies who want to own the rails underneath it.
What happened this week
On November 5, 2026, Firmly announced a $15 million Series A led by Squarepoint Capital, with J.P. Morgan Payments, Mastercard and Samsung NEXT participating (GeekWire, Axios Pro). Total funding is about $20 million.
Firmly’s software lets a retailer sell through AI shopping assistants and marketplaces without building a separate integration for each channel. It handles the merchant side of Mastercard Agent Connect, which launched in September 2026 and links merchants, AI agents and payment providers through one integration. According to the company release, Firmly charges merchants $2,000 to $15,000 a month depending on merchandise volume, and claims its network reaches more than 11 million merchants and over $900 billion in gross merchandise value. Those are company figures and have not been independently verified. It also launched Ask Agent, an on-site shopping assistant that recommends products and completes checkout inside the conversation.
Three other deals landed the same week and fill in the picture:
- Sierra acquired Anon on November 5. Anon’s technology lets agents operate ordinary websites by signing in and filling forms, no API required (Unite.AI).
- Five9 agreed to buy Level AI for roughly $325 million, also November 5 (CXO Digital Pulse), a customer-service bet rather than a checkout one.
- Walmart reportedly “opened its doors to AI agents.” We have only seen aggregator coverage, so treat the specifics as unconfirmed.
The three integration layers
The useful way to understand agentic commerce is as three layers. An agent needs to find products, pay for them, and have a fallback when a merchant supports neither.
| Layer | What it does | Example companies |
|---|---|---|
| Discovery feeds | Expose the catalog (price, stock, attributes) in a form agents can read and compare | Firmly, marketplace product feeds, schema.org product data |
| Checkout and payment rails | Let an agent place an order and pay with a verified mandate from the shopper | Mastercard Agent Connect, J.P. Morgan Payments, Firmly (merchant side) |
| Operate-the-website fallback | Agent logs in and fills forms like a human when no API exists | Anon (now Sierra), browser-use agents |
Discovery feeds
Before an agent can buy, it has to know what you sell. Today that is a mess of scraped pages and inconsistent structured data. Firmly sits here, normalizing a catalog once and publishing it to many assistants.
Checkout and payment rails
This is where the money and the risk are, which is why Mastercard and J.P. Morgan are writing checks. A payment rail for agents has to answer a new question: did the human really authorize this specific purchase? Agent Connect’s pitch is one integration for merchants, one for agents, with the network in the middle verifying the mandate.
Operate-the-website fallback
Most stores will not integrate anything soon. Anon-style technology lets an agent behave like a customer with a browser: signing in, adding to cart, typing a card number. It works everywhere, breaks easily, and merchants cannot easily tell agent traffic from human traffic. Sierra buying Anon says the big vendors expect to need this for years. For how these agents are built, see what an AI agent is.
Who pays whom
Follow the money and the structure becomes clear.
- Merchants pay integration providers such as Firmly a monthly fee ($2,000 to $15,000 in Firmly’s case) to be reachable by agents.
- Merchants keep paying card networks and acquirers their usual processing fees, and the networks want agent transactions to run over their rails rather than some new system.
- Agent platforms (the assistants shoppers talk to) may take a referral or affiliate cut from merchants, the same way comparison sites do now. Expect that to be the contested part.
- Shoppers, so far, pay nothing extra.
Firmly’s investors are not betting on its software alone. They are betting that if merchants connect once through a partner they back, the transactions stay on their networks.
The risks nobody has solved yet
Agentic commerce creates four problems that ordinary e-commerce never had to think about in the same way.
Fraud. An agent with a stored payment credential is a tempting target. If an attacker can steer the agent through a prompt injection on a product page, they can steer the purchase.
Mandate and consent. When an agent buys the wrong thing, who is liable? The shopper said “under $800,” the agent spent $820. Payment networks are designing mandate records to settle exactly this, but the rules are new and untested in disputes.
Returns. Return rates for purchases a human never looked at are unknown. Nobody has public data yet.
Price discrimination. An agent that identifies itself as an agent can be shown different prices. Merchants may be tempted; regulators will notice.
What a small online store should do now
You do not need to sign a $2,000-a-month contract to be ready. Three things are worth doing this quarter.
- Get your structured product data clean. Accurate schema.org Product markup, consistent SKUs, real-time stock and price. This helps search today and is the raw material for every discovery layer.
- Make sure your checkout can be driven by code. If your platform offers a checkout or cart API, turn it on and test it. If it does not, know that agents will reach you through the browser fallback whether you like it or not.
- Decide your agent policy. Will you accept agent orders? From which platforms? With what order limits and return terms? Write it down. A store with a policy can say yes to Agent Connect quickly when the time comes; a store without one will block everything or allow everything by accident.
Our take
Agentic commerce is real enough that payment giants are funding the plumbing, and early enough that the plumbing is still being argued over. Firmly’s raise is small by fintech standards; the signal is in the cap table. For merchants, prepare the data and the checkout now and commit to specific networks later. The layer that wins will be the one that answers the consent question convincingly, and that has not been decided.

Questions, answered
What is agentic commerce?
Agentic commerce is online shopping where an AI agent searches, compares and completes the purchase on a person's behalf instead of the person clicking through a store. The merchant, the agent and the payment network each need a way to talk to one another.
What is Mastercard Agent Connect?
Mastercard Agent Connect, launched in September 2026, is a network that links merchants, AI agents and payment providers through a single integration so a merchant does not need separate work for every shopping assistant. Mastercard is recruiting merchants for it.
Should a small online store allow AI shopping agents?
Probably yes, with limits. Publish clean structured product data, make sure your checkout can be driven programmatically, and decide which agents you accept and at what order size, rather than blocking them all or letting any agent through.
