For startups & scaling businesses
Counsel for the moments you can’t take back.
Some decisions divide a company’s life into before and after. Rubicon is the law firm founders bring into the room for those moments: incorporation, first capital, the big partnership, the exit.
The crossings
Every founder knows the feeling. The decision that divides before from after.
Incorporating the company
The day your idea becomes a company, with founder agreements, equity splits, and a foundation that has to hold for the next decade.
Taking your first outside capital
The first SAFE, note, or priced round, where the terms you accept set precedents that follow you through every future raise.
Making the hire you hope moves the needle
Executive offers, equity packages, and the agreements that protect the company while attracting the person who changes its trajectory.
Signing the transformative partnership
The customer or partner contract big enough to reshape your roadmap, and your risk profile, in a single signature.
Choosing whether to sell, merge, or double down
The decision every founder eventually faces, where preparation made years earlier determines the options on the table.
We’ve sat in those rooms and on those late-night calls, both as counsel and as founders ourselves. These moments deserve preparation, clear thinking, and someone at your side who has helped other leaders make similarly high-consequence decisions.
Counsel to founders across every market cycle.
Supporting high-growth companies at every stage.
From first SAFEs to a $93M Series B.
How we help
Legal support for every stage of the company journey.
“Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiative (and creation), there is one elementary truth, the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then Providence moves too. All sorts of things occur to help one that would never otherwise have occurred. A whole stream of events issues from the decision, raising in one’s favour all manner of unforeseen incidents and meetings and material assistance, which no man could have dreamt would have come his way.”W. H. Murray, The Scottish Himalayan Expedition, 1951

About us →What we believe
Trust is the real currency.

Entrepreneurship makes the world better.
Starting something from nothing is an act of courage and creativity. Our work protects and amplifies that effort.
Clarity beats complexity.
Plain language, framed tradeoffs, and a recommendation. “It depends” is the beginning of the conversation, not the end.
Creativity within constraints.
Great legal work isn’t about saying no. It’s about designing structures that let you build boldly while managing real risk.
