Frequently asked questions

Who runs investment decisions at Yucatan Rock Ventures?

Investment decisions are made by the two co-founders, Stephen G. Pearse and Robert G. Pearse. Stephen was the founder and CEO of Cyras Systems, the optical networking startup whose sale to Ciena generated the family's core wealth. Robert serves on the boards of multiple public companies, including Star Equity Holdings. There is no known external investment committee.

How does Yucatan Rock source its deal flow?

The firm's sourcing network is anchored in the telecommunications and optical networking ecosystem that surrounded Cyras Systems and Ciena. This technical alumni network, combined with the Pearse family's relationships in deep-tech and applied-science circles, produces a referral-heavy pipeline that bypasses the traditional venture capital auction process. The firm does not market itself publicly to deal sources.
