InstantGroups

Hey HN, I built InstantGroups to finally solve the scheduling mess that happens any time three or more people try to meet, especially across teams, companies, and time zones. The idea came out of pain: At my last company leading growth I was constantly coordinating sales calls with multiple stakeholders, panel interviews, and team planning sessions, and despite shared calendars, nothing worked once multiple busy people were involved. Existing tools fell short for wrangling groups, especially with external participants. So I built something better. InstantGroups is an AI group meeting…

  • Tapflow 2.0▲1,125

    We 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 →…
