PBJ Capital

PBJ Capital is an independent venture firm that invests in early-stage technology companies. We are based in Boston, Massachusetts and we have a passion for innovation and disruption. We are not your typical venture capitalists. We are the three managing partners of Arrowstreet Capital, a large investment management firm that manages over $100 billion in assets. We have decades of experience in quantitative finance, machine learning, and data science. We have seen how technology can transform industries and create value for society. We started PBJ Capital in 2019 to pursue our vision of investing in the future. Our name reflects our initials: Peter Rathjens, Bruce Clarke, and John Campbell. We are hands-on investors who work closely with our portfolio companies to help them grow and succeed. We invest $1 - $5 million in Seed- and Series-A-stage companies across various sectors, such as biotechnology, healthcare, consumer, enterprise, and fintech. We are always looking for passionate and driven founders with innovative and disruptive ideas. If you think you have what it takes to join our portfolio, please reach out to us on our website or our LinkedIn page. We would love to hear from you and learn more about your vision. Together, we can make a difference in the world.
