Signal Lake

Eric P. Jette is the Managing Partner and the firm's key decision-maker. He has led Signal Lake since its founding, sourcing and managing the portfolio across enterprise infrastructure sectors. There are no additional named investment partners disclosed publicly.

Signal Lake targets Seed and Series A rounds, occasionally participating in later-stage insider rounds for existing portfolio companies. The firm prefers early, concentrated bets in technical companies where it can obtain a meaningful ownership position and board representation.

The firm has deployed capital into enterprise infrastructure broadly: optical networking systems, data center virtualization software, network security platforms, and adjacent industrial-technology categories. Known bets include Infinera (optical transport), Softricity (application virtualization), and Arbor Networks (DDoS security).

Signal Lake operates as a traditional venture capital firm raising external limited-partner capital, not a family office. The firm is registered as an investment adviser with the SEC per public filings, consistent with institutional fund structures rather than single-family capital.

Public filings indicate Signal Lake leads Seed and Series A rounds and takes board seats, consistent with a lead-investor posture. The firm has also followed on in later syndicated rounds alongside larger venture firms when portfolio companies scale into growth stages.

The firm invests primarily in the United States, with portfolio activity concentrated in the Northeast — particularly the tri-state area — and the West Coast. There is no evidence of an active international deployment strategy.

There are no disclosed opportunity funds, growth vehicles, SPVs, or philanthropic entities associated with Signal Lake in public records. The firm appears to operate a singular commitment-focused fund structure, releasing minimal information on fund size or limited partner composition.
