BlackOak Partners works with founders and CEOs at the moments where decisions get consequential—on capital, positioning, legal infrastructure, investor communications, and what comes next.

Every engagement is informed by years on the investor side—evaluating deals, sitting in board meetings, and seeing firsthand what separates companies that raise and scale from those that don't. 

The best practices are there. We bring them in, apply them where they fit, and save the hard thinking for the decisions that are actually new.

We work across five areas: Fundraising Strategy, Legal Operations, Operational Alpha, Growth Strategy, and Transaction Advisory.

Founded by Liam Reilly—former investment principal and general counsel at a multi-fund venture firm with $100M in AUM deployed, oversaw 20+ new investments, and direct advisory work with founders and CEOs across a portfolio of 50+ companies.
