FAQ

Who can take advantage of the Experiment Fund?

Everyone, regardless of university affilation, nationality, age, or prior experience. Read more about our Method.

What kind of help can I expect?

We invest seed capital, make our team part of your team, and connect founders with world-class advisors, operators, and top-tier growth financing. Our deep connections in Cambridge, Silicon Valley, and abroad are marshaled in service of achieving your vision.

Do you give grants? Are you an incubator?

The Xfund does not make grants; we make investments. We are also not a cookie-cutter incubator where all teams sign up to templated investment terms.  We make seed investments on a case-by-case basis and partner with the best teams to build transformational technology companies. In that quest we work closely with nationally respected incubators and angel investors.
