F4 Fund Research
Investment Thesis
F4 Fund is a founder-led venture capital firm backing relentless founders building ambitious companies. Founded by David Kaye, a serial founder and operator with three successful exits and two decades in the gaming industry, F4 Fund combines operational expertise with capital to support founders at early and growth stages.
The fund's thesis emphasizes finding exceptional founders ("we back the relentless") who demonstrate the drive, persistence, and vision to build category-defining companies. David Kaye's background as co-founder of Snapshot Games (acquired by Embracer Group) and his role at Iron Realms Entertainment provides deep operational experience in building teams and scaling businesses.
Sector Focus
Based on the portfolio, F4 Fund invests across multiple sectors:
- Gaming & Entertainment: AfterHour, Omada Game, Midsummer Studios, Incan Descent Games - reflecting founder David Kaye's deep gaming expertise
- Consumer Apps & Social: Blush (dating app), Blueberry Social, Valley - consumer-focused platforms
- AI/ML & Productivity: Howie (AI), Flockshop (AI), Superposition (AI), Series (AI), Boby (AI), Podcast AI, HeyAto (AI) - growing focus on AI tooling
- Developer & Creator Tools: Camera Intelligence, Podcast AI, Series - tools for content creators and developers

The portfolio suggests a platform-agnostic approach with strong conviction in founder quality over sector specificity, though with notable depth in gaming and emerging AI/ML categories.

- Pre-seed investments in teams with compelling visions but early product
- Seed investments in companies with initial product-market signals
- Select Series A follow-ons in high-conviction portfolio companies
The fund positions itself as a founder partner rather than purely financial provider, leveraging David Kaye's operational expertise to support portfolio company scaling.
