We are not a venture firm. If you are an entrepreneur with a great idea and a small team looking for funding, please seek out one of our partners. We are not an incubator or accelerator. If you are an existing company looking for amplification or mentorship, TechStars might be a great option.
We are a startup studio. We develop ideas internally and validate or kill them. We then take the next steps, turning the best ideas into products with actual customers.

That's where you come in. Building a great startup is hard. Really hard. It requires domain expertise, uncommon talent at all levels, great execution, perfect timing, and a little luck. If you are an experienced, execution-oriented business person or technologist, looking to run and build a startup that is ready to take off, come talk with us.
