Our Model

Our mission at Seraph is to bring successful individuals together to create wealth by intelligently enabling entrepreneurs to found innovative companies.

We offer our entrepreneurs constant and dynamic support, from agile funding to expert guidance from our network.

We offer our investors access to a diversified portfolio of high quality done-deals.

These two key offerings are sides of the same coin: the more successful people we bring together, the better we can support the companies we fund.

Successful angel investment is incredibly difficult. At base, it requires:

  1. access to high quality and diverse investment opportunities,
  2. significant expenditure of time,
  3. deep knowledge across multiple industries,
  4. familiarity and expertise in business economics and value propositions,
  5. professional understanding of legal and financial terms and conditions,
  6. know-how in exits.

Seraph’s Structured Angel Fund provides the solution to these challenges. Our team, supported by our extended network, leverage our broad experience and deep knowledge to find, vet, and negotiate deals which we compose into our portfolios of 20-30 companies.

Our LPs benefit not only from this professionally managed portfolio, but also from the option make deal-by-deal co-investment. Portfolio companies present directly to our LPs, giving our network a chance to hear directly from the management, from the Seraph investment team. They can then choose to supplement their portfolio with additional exposure to opportunities they think are the most promising.
