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.
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.
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. 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].

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.
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? 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.
