Our Proposition

Client Focus
We serve mid-market companies, start-ups and emerging companies, family offices, angel, VC, and private equity investors, and large companies for whom a large firm is overkill for the task at hand.

We also act as US – or global – outside general counsel, and with our extensive legal contacts within the US and around the world we can assemble the best global team our clients need to handle the job.
