Senior🎓
Top SchoolCooper Maruyama is a founder and seasoned software engineer with 13 years of experience building product-focused engineering teams and startups in the crypto and conversion optimization spaces. He founded darkmatter and ICO Stats and previously co-founded and led engineering at CoinCircle, combining hands-on development with product strategy across blockchain analytics and fintech. His background includes senior engineering roles at MarketShare and Faraday Future and early-stage entrepreneurship running a CRO agency that executed hundreds of A/B tests. Based in Los Angeles, Cooper pairs a hacker’s instinct—“I just click keys on a keyboard, but in a very specific order”—with formal study in cybersecurity and a foundation in mathematics and philosophy. He’s comfortable shipping full-stack systems, measuring real-world impact (e.g., ICO performance vs. holding crypto), and translating experimentation insights into growth. Colleagues describe him as a pragmatic builder who thrives at the intersection of data, product, and infrastructure.
