Firmly has raised $15 million to help retailers sell through AI shopping assistants without building a separate integration for every new channel. The Seattle-area startup’s approach connects directly to retailers’ systems, keeping their payment providers and customer relationships in place.

What happened
GeekWire reports that the Series A was led by Squarepoint Capital, with J.P. Morgan Payments, Mastercard and Samsung Next among the investors. The round brings Firmly’s total funding to about $20 million.
Firmly connects retailers’ existing online stores to AI assistants and other shopping channels, so customers can buy through those services without visiting a retailer’s website. The company also offers Ask Agent, a shopping assistant for retailers’ own sites. Mastercard is both an investor and a commercial partner: Firmly handles the merchant side of Mastercard Agent Connect, which links merchants, AI agents and payment providers through one integration.
Why it matters
Shopping agents are starting to make the leap from product recommendations to purchases. That creates a practical headache for retailers: each new assistant or marketplace could mean another connection for catalogues, stock, payments and checkout. Firmly is betting that merchants will pay to avoid building those links one by one, while retaining their existing payment providers and customer relationships.
The funding also lands amid competing approaches. Meta’s Muse can browse and buy with a user’s approval; GeekWire reports that Amazon has blocked Muse from its site and is suing Perplexity over its shopping agent. Firmly’s route is different: connect with retailer systems by permission, rather than having an agent click through their webpages.
Our read
The useful idea here is not that an AI agent can shop. It is that merchants may need a common bit of plumbing if shopping agents multiply. Firmly has money, named retail customers and a Mastercard partnership behind that pitch. The test is whether its integrations make agent-led purchases easy for retailers to support, and worthwhile enough for shoppers to use. Commerce has never lacked middlemen; the new question is which ones save anyone time.
What to watch
- Whether Mastercard brings more merchants onto Agent Connect.
- How many retailers adopt Firmly’s integrations and Ask Agent.
- Whether customers actually complete purchases through shopping assistants.
- How retailers balance easier access with control over payments and customer relationships.
Discussion spark: Should retailers let AI assistants take customers through checkout inside third-party apps, or keep the purchase on their own sites even if that means more friction?
