Flapico is a product company rebuilding the web for its two readers: the humans who open a page, and the agents that increasingly read it first.
Flapico is a technology company specialising in AI & Infrastructure. We operate like a lab where we build products for next (and current) generation of users on the web. Flapico is a lab. We ship products in AI and infrastructure — and, more often than not, services. Almost everything we build, we've run ourselves first. Our lean size gives us a luxury that many companies don't have — failing fast and loud. This philosophy also reflects well in most of the software we write — we believe errors should be loud and clear. In business & in software. Some of these work, some don't. We're equally fond of both, regardless of their impact onfrom flapico.com

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
