What you likely need
Justin is a highly accomplished serial founder and active investor with three major exits, multiple current ventures, and a deep network from his YC and Twitch days. His current focus spans Stash (gaming commerce), Rye (eCommerce APIs), and Goat Capital (co-founding fund), giving him an unusually broad surface area to manage simultaneously. The biggest leverage point right now is likely clarifying which of his current bets deserves the most founder attention and capital.
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.
- tacticalPrioritize one of Stash or Rye as your primary founder focus — running two early-stage companies simultaneously risks splitting founder attention at the critical growth stage.
- fundraisingRye has $14M raised and a developer-tools angle that fits the current AI-agent commerce wave — consider timing a Series A to capitalize on the Skyfire/KYA partnership momentum.
- introsTap your YC alumni network (first batch, 2005) and your former Partner relationships to source warm intros for Stash's enterprise game-publisher pipeline.
- positioningPublish a clear thesis for Goat Capital's co-founding model to attract inbound deal flow from founders who want an operator-investor, differentiating from pure financial VCs.
- tacticalWith 73 investments and a recent FLORA Series A, systematically identify your top 10 portfolio companies for pro-rata follow-on rights before they hit Series B.
- positioningStash's '30% platform fee elimination' narrative is a strong hook — publish a founder case study or data report to drive organic press and game-developer sign-ups.
- wellbeingManaging two active co-founder roles plus a VC fund is a significant cognitive load — consider a quarterly personal review to assess where your energy is creating the most value.
