Erik Johnson built Facebook's business in Asia from the ground up, ran Meta's global Marketing Sciences team, led Microsoft's consumer business development and M&A, and headed Facebook's Atlas ad-measurement platform—giving him a background rooted in scaling distribution, monetization, and measurement inside major tech platforms rather than a traditional finance-only path. As a hands-on regional leader, he made frequent trips to India, championed mobile and feature-phone strategies for emerging markets, and pushed brands to rethink how they used social media, showing an operating style focused on practical, on-the-ground execution rather than distant oversight.

Notable Investments
J4.Ventures is led by a team of operators—including a former Microsoft corporate VP who ran M&A and investments, a repeat pricing-software founder whose company sold to Instacart, and a Stanford professor focused on security and AI—and typically invests as a non-lead investor writing first checks in the $100k–$1M range. The fund’s seed-stage bets span an unusually broad range, from climate hardware like Molten Industries to AI-driven health devices and teen mental-health platforms, with a notable presence in Seattle’s AI2-adjacent startup scene and support for founders focused on economic mobility for lower-wage workers.
