What if we don't have a fully-formed idea yet?
No problem. Having a lot of experience with startups, I specialize in turning early-stage ideas into actionable plans. I offer a prototype package that is designed to help startups validate concepts quickly and confidently.
What industries do you specialize in?
I've worked on projects in sectors like finance, blockchain, and climate tech. My focus is on solving real-world problems regardless of industry.
