Investment thesis
Seraph Group invests its own capital in early-stage companies across diverse industries, sectors, and geographies, then makes the same opportunities available to its network of accredited-investor LPs for co-investment at identical terms. Opportunities are vetted by a full-time investment team and industry experts. The firm operates structured angel funds that take positions in 20+ early-stage companies under a partner's direct management, plus growth equity funds that make follow-on investments in its best-performing portfolio companies. It also enables members to self-select and build their own portfolios across early and growth stages, providing startups with a single, well-connected line item on the cap table.
