When a Perplexity user asks the AI search app to find a pair of running shoes, the answer increasingly comes with a buy button attached. The infrastructure behind that button, in at least one prominent integration, belongs to a Seattle seed-stage startup called firmly.ai, which announced a partnership with Perplexity earlier this year to power shopping inside the AI search experience [GeekWire].
That is the bet firmly is making: the next decade of e-commerce will not happen on merchant websites. It will happen inside articles, AI chat answers, creator content, and ad impressions, and somebody has to make those surfaces transact. Firmly is selling itself as that connective tissue, an agentic commerce platform that lets a publisher, a creator, an ad network, or an AI assistant turn any digital impression into a completed purchase without asking the underlying merchant to change a line of code on its own site [firmly.ai].
The bet
Firmly's pitch to buyers is a streamlined embedded checkout that sits inside someone else's surface. CJ, the affiliate network formerly known as Commission Junction, has deployed firmly's checkout on publisher pages including USA Today, according to CJ's own materials [CJ]. The two companies announced a strategic partnership aimed at native commerce for publishers and merchants [Yahoo Finance]. The wedge is the no-merchant-integration claim: if firmly can genuinely transact for a Nike or a Sephora without that brand standing up a new API endpoint or shipping engineering work, it removes the single most painful step in distributed commerce deals.
The ICP here is reasonably clear. The buyers are publishers losing display revenue, affiliate networks like CJ trying to graduate from link-clicking to actual conversion, creator platforms looking for a take rate, and the new class of AI search and assistant companies (Perplexity being the headline example) that need a commerce layer they did not build themselves. The budget owner inside a publisher is usually the head of commerce or the chief revenue officer, not IT, which matters because it shortens the procurement cycle considerably. The renewal motion, candidly, is the open question.
Why it could be big
The tailwinds are real and they are converging fast. Affiliate commerce has spent twenty years sending traffic to merchant sites and praying for conversion. Agentic commerce, where an AI agent completes the purchase on the user's behalf, requires an entirely new transaction rail because the agent is not a browser session on shop.nike.com. Digital Commerce 360 framed Perplexity's firmly partnership as part of the AI search company's broader push into e-commerce, a category every major model provider is now chasing [Digital Commerce 360]. If even a fraction of search behavior shifts from Google to AI assistants, the surfaces that need embedded checkout multiply quickly.
Firmly's positioning, an agentic commerce platform for instant purchases in any digital experience [firmly.ai], lines up with that shift. Industry trade press covered the company's launch of a unified Buy Now platform aimed explicitly at the agentic commerce moment [AIThority] [Payments Industry Intelligence]. The credible upside, if the wedge holds, is becoming the default checkout primitive for the non-merchant internet: the Stripe of surfaces that are not the merchant's own site.
The team and traction
Firmly is led by CEO Kumar Senthil [GeekWire]. The company describes its team as carrying twenty-five years of experience at the intersection of media and commerce, with prior stops including eBay, News Corp, and VICE Media [firmly.ai]. That background matters for this particular wedge, because selling embedded commerce into publishers and ad networks is a relationship business, and the buyers are people who have spent careers watching media-commerce integrations get promised and under-deliver. Operators who have lived inside News Corp and VICE know which doors to knock on.
The public traction signals are the Perplexity integration [GeekWire], the CJ partnership with deployment on USA Today pages [CJ] [Yahoo Finance], and the launch of the unified Buy Now platform [AIThority]. For a seed-stage company, landing a named AI search partner and a top-three affiliate network in the same year is a genuinely strong opening hand.

The honest counterfactual
What the bears will say: embedded checkout is a famously hard category to defend. Bolt, Fast (now defunct), Shop Pay, and PayPal all built or tried to build versions of one-click checkout, and the category has a track record of compressed margins and contested attribution. The realistic competitive set firmly faces is not just other agentic commerce startups, it includes Stripe's own emerging agent toolkit, Shopify's commerce APIs being repackaged for AI surfaces, and incumbents like PayPal and Affirm that already sit on consumer trust. Any large publisher or AI assistant evaluating firmly will also evaluate building it themselves with Stripe primitives.
The bull answer, which is the answer firmly's deployments support, is that the no-merchant-change architecture is the actual moat. Stripe and Shopify both require the merchant to integrate. If firmly has genuinely solved the problem of transacting on a brand's behalf without that brand's engineering involvement, the company is selling something Stripe is not, and the CJ and Perplexity wins are early evidence that sophisticated buyers see the difference.
What to watch
The next twelve months come down to three things. First, does the Perplexity integration produce disclosed conversion or GMV numbers that the company can stand behind publicly? Agentic commerce is at the stage where one credible case study reshapes the category. Second, does firmly extend beyond CJ to a second top-tier affiliate network or a second named AI assistant, which would signal the wedge is repeatable rather than relationship-driven. Third, the funding round. A seed-stage company with a Perplexity logo and a CJ deployment is a Series A story, and the size and lead of that round will tell the market whether investors view firmly as the checkout layer for agentic commerce or as a feature inside someone else's roadmap.
The ICP is publishers, affiliate networks, creator platforms, and AI assistants who need to transact on surfaces they do not own. The realistic competitive set is Stripe's agent tooling, Shopify's commerce APIs, PayPal, and any in-house build by a sufficiently motivated platform. That is the procurement conversation buyers should be having, and on the evidence so far, firmly has earned a seat at it.
