What you likely need
You're a technical second-time founder with real revenue traction but a thin public signal and a fundraising process that hasn't formally launched yet — Festival events that put you in rooms with YC alumni, e-commerce-focused investors, and compliance-tech operators will unlock the warm intros and narrative sharpening you need most. You'll get the most out of small, high-trust dinners where your Enrolled Agent credential and six-figure ARR story can land in conversation before it lands on a pitch deck.
Would you attend these IRL Festival events?
We will tune and customize your Founder Festival experience to make sure you get invited to the events that would be most valuable to you.
