The Backstory
Engineer · Inventor · Attorney
From Napkin to Airplane
We like working with bleeding-edge startups because we’re actual engineers. Our founder is a real electrical engineer who has taken inventions from napkin to airplane — including work on the flight computer for the YF-22 Raptor. That’s the kind of intellectual property counsel you get here.
Learn more →Why “Villa Mars”
The name Villamar means “Villa by the Sea,” but the Villamar domain was already taken. Since there were two Villamars, this created the perfect mnemonic device: picture a Villa on the planet Mars, and you will always be able to find us!
