What you likely need

You're a legendary operator with two billion-dollar exits now building HASH at the earliest stage, which means the highest-leverage gatherings for you are intimate rooms with institutional seed and Series A investors who already know your name, plus developer-ecosystem insiders who can seed HASH adoption from the inside. You'd also benefit from small roundtables with fellow second- or third-time founders navigating the psychological reset of going back to eight employees after running a company of hundreds.

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 dinner for two- and three-time founders who've raised institutional rounds post-exit, where Joel can pressure-test HASH's Series A narrative with GPs from Benchmark, a16z, and Spark Capital who already have his number
positioningA roundtable with 6-8 CTOs and staff engineers from AI-native companies actively building internal knowledge graphs, to sharpen HASH's positioning against Notion and Confluence around a single wedge — AI-ready ontologies for engineering teams
introsA Stack Overflow alumni and developer-tools founder dinner — pulling from the SO for Teams and SO alumni network — to explore HASH integration and partnership paths into the 100M+ monthly developer audience Joel already built
hiringA happy hour for senior developer-relations and developer-growth leads currently open to early-stage roles, curated from the Stripe, Vercel, and Cloudflare DevRel alumni networks, so Joel can recruit HASH's first dedicated growth hire
tacticalA tactical lunch with 4-5 developer-audience newsletter and blog founders — including Substack engineering writers with 50K+ subscribers — to help Joel rebuild a publishing cadence on joelonsoftware.com as a top-of-funnel engine for HASH
introsA dinner for Trello and Atlassian alumni angels and operator-investors to expand Joel's angel portfolio beyond his 2 known checks, with warm deal flow from founders who specifically want a legendary developer-tools operator on their cap table
wellbeingAn intimate offsite dinner for 8-10 founders on their third or fourth company — people who've had a major exit and chosen to go back to zero — to share honest frameworks for pacing, team size discipline, and avoiding the burnout that comes with rebuilding after a billion-dollar outcome
