About us

We help you build the next wave of generational companies only MIT could spark.

Our goal

At SBXi, our mission is to empower MIT Alumni founders with the resources and capital to create large, impactful companies across any sector.

We are jointly backed by eight firms and write $10K-$100K checks on SAFEs and $100K-$1M checks when there’s a qualifying term-sheet we can match.

Proudly backed by



Many VC firms feel like a black box. SBXi aims to be as transparent as possible in our approach.



The faster you close your round, the faster you can focus on what’s important; building your company. One application, one recorded pitch, then a decision.


From MIT for MIT

All eight partners have an MIT affiliation and are interested in being a small but meaningful part of the next great companies to come out of MIT.



Every eligible company who applies will receive a decision one way or the other.


You Decide

We offer community building, networking opportunities, and other events. With that said, It’s up to you how involved you want to be with the fund. There are no required programs or events to attend.



Through various initiatives, we will try to expose you to investors, customers, mentors, and other founders.
