Pick a subscription and build its replacement.

That software subscription you keep complaining about? You’ve got one day to build something better.

Join us at the Seldon Speakeasy in SoMa. Pick a paid product, rethink a key workflow and build an alternative someone would actually switch to.

  • 🛠️ Pick your target. A dev tool, a design tool or a CRM - it's your call. Choose something you can meaningfully reinvent in a day. Bring a team or find your people when you arrive.

  • Build with anything. Test with Wren. Use your favourite stack and coding tools. Put Wren, Seldon’s QA agent, to work while you build: test real journeys through your app, fix what breaks and run it again. We’ll provide access, credits and hands-on help.

  • The demo has a twist. Someone from the Seldon team runs the demo. Can they do what your product promises? You’ll get to explain your idea, then let them try it.

  • 🏆 Three ways to win. Prizes for best overall product, most original reinvention and people’s choice. Originality, usefulness and whether it actually works all count. Up to $5k in prizes, plus Claude API credits provided by Anthropic.

  • 🍸 Finish at the bar. Demos, prizes and drinks behind the red velvet curtains. Meet the Seldon team and the people you’ve spent the day building alongside.

To qualify for prizes: submit a working product and Wren test results for at least two core workflows, rerun against your final build.

Bring a laptop and a subscription you’d like to stop paying for.
