Frequently asked questions

Who runs investment decisions at SDL Ventures?

Managing Director Don Scifres and Vice President Mike Foster have led the investment function since the firm’s 2003 founding. Scifres is the former CEO and Chairman of SDL, Inc., and Foster was its CFO. Foster stepped back from his partner role in 2024 but continues to consult for the firm, leaving Scifres as the primary decision-maker.

How does SDL Ventures source proprietary deal flow?

The firm relies on Don Scifres’ technical network built over four decades in optoelectronics and semiconductor lasers. His standing as a National Academy of Engineering member and 140-patent holder gives the firm direct access to founder-led science companies, particularly in biotechnology and optical technologies, that often fall outside conventional venture pipelines.

Does SDL Ventures participate in fund commitments or only direct deals?

Every known deployment has been through direct equity investments in operating companies. The firm states its strategy as early-stage direct investing with initial checks of $500,000 to $2 million. No fund-of-funds commitments or LP allocations to outside managers are disclosed.
