i’ve spent the last few months traveling across europe with @joinebl, looking for people who burn to build: who chase hard problems not out of ego, but because they can’t imagine doing anything else.

@jointhebridge isn’t just about curating talent. we’re building the rooms where belief compounds and pressure turns into possibility.

can’t wait to bring them all together this summer.

until then, making three final stops: romania, poland, and estonia this week.

when we started thinking about @joinebl, we wanted to make hackathons great again - meaning: 
> high-signal: we're curating a high-density of top talents (20ppl max)
> useful: people work on whatever they want, no theme, no BS projects
> resourceful: they get access to all the resources they need

Hey @perplexity_ai — we’re working on a hackathon project that could grow into a real startup, and we’d love access to the structured output API for our demo. Any chance you could hook us up? We’re not on a Tier 3 key (yet!).

@AravSrinivas @tylertate @alipanju_ can you help ?
