Rebel leverages data science and Silicon Valley’s most accomplished founders to invest in a diversified portfolio of top Y Combinator startups
Investors, Partners, & Founders
We build long-term relationships based upon our core values of trust, transparency, and mutual respect. We choose our LPs, partners, and portfolio companies selectively and then support each other for life.
Making the Art of Venture Investing a Science
We use a proprietary machine-learning algorithm developed by an MIT data scientist to screen startups based on exit probability and expected ROI.
To Silicon Valley & Beyond
Rebel Fund is built from the ground up to leverage the expertise of top Y Combinator alumni to identify, access and support the world's most exciting technology startups.
Building a Diverse Portfolio of Talented Founders
The vast majority of founding teams Rebel Fund supports have a least one diversity factor, such as a female, black, latinx, or international co-founder.
A team of top Y Combinator alumni who have co-founded companies now valued over $85B in aggregate and support Rebel’s due diligence, investment decisions, and portfolio support part-time while running their respective companies.
