JAM Fund

JAM Fund is a Los Angeles-based venture capital firm founded by Justin Mateen, a co-founder of Tinder, establishing itself as a prominent early-stage investor in the United States. Launched with a strong entrepreneurial background at its helm, the firm primarily targets visionary founders who are poised to disrupt large markets across various sectors. JAM Fund's investment philosophy emphasizes a hands-on approach, leveraging Mateen's extensive experience in scaling consumer technology companies to support its portfolio.

The firm maintains a broad investment mandate, actively seeking opportunities across diverse industries including consumer technology, enterprise SaaS, fintech, healthcare, and artificial intelligence. JAM Fund focuses predominantly on pre-seed, seed, and select Series A rounds, aiming to be the first institutional capital for promising startups. Their strategy is to identify companies with strong product-market fit potential and provide not just capital, but also strategic guidance and network access to accelerate growth.

JAM Fund has demonstrated significant growth in its capital base since its inception. The firm successfully raised its first fund, JAM Fund I, with $20 million in 2020, followed by JAM Fund II, which closed at $100 million in 2021. Most recently, JAM Fund III secured $200 million in 2023, reflecting increasing investor confidence and the firm's expanding capacity. This growth enables JAM Fund to write initial checks ranging from $500,000 to $5 million, and sometimes more, positioning them as a substantial early-stage partner for ambitious startups.

Beyond financial investment, JAM Fund prides itself on being a founder-friendly firm that offers operational support and strategic insights. Mateen and his team actively engage with portfolio companies, providing mentorship on product development, market strategy, and talent acquisition. This hands-on involvement is designed to help founders navigate the challenges of early-stage growth and scale their ventures effectively, reinforcing JAM Fund's commitment to long-term partnership.
