What you likely need

You are a high-profile serial founder and current CPO/co-founder of Gusto, a $9.5B+ company that has raised over $520M and crossed $1B in annual revenue — your founder signal is exceptionally strong. Your angel investing activity is confirmed but relatively modest in public footprint, suggesting room to build a more visible investor brand if that's a priority. Your GitHub presence is dormant, which is expected for a CPO-track founder, but activating public technical content could reinforce your builder credibility.

Are these your current priorities?

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.

  • positioningWith Gusto crossing $1B in revenue and a $9.5B valuation, begin positioning publicly for an IPO narrative — engage with financial press and analysts to shape the story ahead of any S-1.
  • positioningFormalize your angel investing activity with a public portfolio page or AngelList profile to attract deal flow commensurate with your Gusto brand and network.
  • introsLeverage your YC W12 alumni status to mentor current YC batches — this deepens deal flow for angel investments and reinforces Gusto's brand among the next generation of founders who will need payroll.
  • hiringDouble down on Gusto's API/platform strategy by recruiting senior developer-relations talent to grow the vertical SaaS partner ecosystem you've publicly championed.
  • positioningPublish more founder-to-founder content (you already have a well-received YC post) — a regular cadence on LinkedIn or Substack would amplify your thought leadership and Gusto's employer brand.
  • tacticalConsider open-sourcing a small internal tool or SDK from Gusto's engineering work to reactivate your GitHub presence and signal technical depth to the developer community.
  • wellbeingAt 14+ years as a co-founder of a high-growth company, proactively invest in founder coaching or peer CEO groups (e.g., YPO, Operator Collective) to sustain energy through the next growth phase.
