What you likely need
You're navigating one of the highest-stakes pivots in developer-tools right now — going closed-source with a beloved open-source product — and Festival events can accelerate both the revenue proof points and the narrative control you need before a Series B. The most valuable gatherings for you are tight-knit dinners with enterprise SaaS founders who've made similar PLG-to-enterprise transitions, roundtables with B2B infrastructure investors tracking ARR inflection stories, and small rooms with senior GTM and DevRel talent who've scaled exactly this motion before.
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.
- fundraisingA Series B prep dinner for $1M–$5M ARR enterprise SaaS founders who've recently pivoted GTM motion — to pressure-test ARR documentation, NRR benchmarks, and investor narrative before hitting the fundraising circuit
- positioningA closed-door roundtable with founders who've made the open-source-to-closed-source or PLG-to-enterprise transition (think Hashicorp, Airbyte, or Grafana-era operators) to swap playbooks on retaining developer goodwill while accelerating enterprise revenue
- hiringA happy hour targeting senior enterprise GTM leaders with scheduling, calendar-infrastructure, or B2B SaaS backgrounds — specifically people who've built and owned the first enterprise sales motion at a 30–50 person PLG company
- positioningA founder dinner focused on enterprise security and compliance positioning — SOC 2, ISO 27001, HIPAA — for B2B SaaS founders actively differentiating against legacy incumbents like Calendly or Docusign on trust and data residency
- fundraisingA roundtable with B2B infrastructure and developer-tools investors (Bessemer, Redpoint, OpenView) actively tracking PLG-to-enterprise ARR inflection stories ahead of Series B deployment cycles
- introsA Powerset-style founder-investor syndicate dinner for Series A operators making their first 2–3 angel bets — to build structured deal flow and co-invest relationships without pulling focus from Cal.com's critical growth year
- hiringAn office hours session with experienced developer advocates and open-source community leads — ideally from Vercel, Supabase, or PlanetScale — who've managed a fork or MIT-licensed community alongside a commercial closed-source product
- wellbeingA small wellbeing dinner for high-visibility founders who've made a single defining strategic bet in the last 12 months — a structured, off-the-record space to honestly assess whether the pivot is paying off before doubling down further
