About
While this is a new UpCounsel profile, I’ve completed 400+ UpCounsel projects over the past four years under my prior firm's name.
My common work includes
- Entity formation and founder setup (LLC/Corp formation, cap table basics, equity grants)
- Commercial contracts (customer/vendor agreements, employee agreements, core contracts)
- Capital raises and M&A… read more transactions (prep, diligence readiness, deal counsel)
- Outside counsel support for day-to-day questions as the business grows
If you’re looking for practical legal support and aren’t sure where to start, book a quick intro call. I’ll get clear on what you’re trying to do, flag the key risks, and propose a straightforward scope and fee before we begin.
