Rebel One

What Rebel One does

Rebel One (RBL1) is a privately held education and community platform founded in 2017 and headquartered in Brooklyn, NY, that serves two complementary audiences in the venture ecosystem: purpose-driven investors (VCs, angels, and emerging fund managers) and bold, unconventional startup founders building for impact. The platform is structured around tiered membership and training programs, including a free 5-week VC Fellowship, a paid VC Membership with 200+ video lessons covering sourcing, due diligence, financial modeling, and fund strategy, and an Emerging Managers consulting program covering fund formation and LP fundraising. For founders, it offers a 30+ hour self-paced training course (Hustle) covering lean startup methodology, pitch deck creation, financial modeling, and fundraising, alongside ImpactMatch — an investor-matching tool that connects founders with VCs and angels actively writing checks.

The product surface is delivered primarily through Thinkific for course hosting and Airtable for waitlist and matching intake, with email notifications routing investor-founder introductions. The platform includes a 500+ member community that participates in live deal reviews and shares deal flow, a private resource library of 500+ startup pitch decks and investment committee memos, and a VC & CEO Fireside chat series. A password-protected Studio platform is in private preview, indicating exploration of additional product lines.

Rebel One generates revenue through annual subscriptions to VC Membership and Founder Programs and through multi-year consulting engagements in the Emerging Managers program; pricing is not publicly disclosed for any paid tier. The company operates with 11-50 employees, has no disclosed funding rounds or institutional investors, and is founder-led by Sergio Marrero. Named customer evidence is limited to testimonial relationships with Kapor Capital and Multicare Capital Partners rather than disclosed enterprise contracts.
