Koba Ventures · Los Angeles, CA
Growth marketing and AI systems, built and run by one operator.
I'm Forrest Kobayashi. I build revenue engines for early-stage startups and design AI agents that do the marketing production work teams don't have headcount for.
Where I add value
Each venture stands on its own, but they share the same underlying discipline: build the system, prove it with real numbers, then hand over something that keeps working.
Bunker Hill Agents
AI agents that take over the repetitive marketing production work — creative variation, performance analysis, campaign structuring — so lean teams can test and ship faster.
Performance marketing systems for early-stage startups
Demand generation, paid media and email marketing systems to generate measurable, incremental pipeline for venture-backed teams.
