Paul Sieben, Head of O’Melveny’s Silicon Valley office, represents all stages of technology companies as well as numerous venture capital firms, other investors and market participants. Paul’s practice is focused on M&A, venture capital, private equity, early liquidity transactions, spin-offs, recapitalizations, public equity offerings and private debt transactions.  Paul has served as lead counsel on hundreds of venture capital, angel and private-equity financings, more than a hundred and fifty M&A transactions of all sizes, and a significant number of recapitalizations, public offerings and other transactions — many on behalf of, or opposite, major tech companies, venture capital and private equity firms.

Paul’s practice stems from his relationships with a combination of early and late stage venture capital firms, large public technology companies and from his startup company practice, where he handles formation, founder-related matters, seed investments and venture capital financings for early-stage companies and then continues to represent them in various matters including later stage financings, M&A and corporate governance matters as they grow into larger private and public companies.
