Operator Partners Research
Investment Thesis
Operator Partners is a founder-led venture capital firm founded by seasoned entrepreneurs with billion-dollar exits. The fund's core thesis is "we are operators funding operators"—providing capital from the partners' own personal wealth, not outside investors. They believe the best venture support comes from those who have built and scaled companies themselves. Rather than taking board seats or leading rounds, they position themselves as hands-on operational advisors who understand the challenges of building, scaling, and exiting companies.
Fund Structure and Capital
Operator Partners is a self-funded $40M-$70M venture fund with a unique structure: all capital comes from the partners' own money, with no limited partners (LPs). This aligns them completely with their portfolio companies' success and removes conflicts of interest. The partners are personally invested in every decision, creating a strong incentive for rigor and operational excellence.
Fund II was closed in 2024 with $40M-$70M in committed capital, and the fund is actively deploying into new investments as of January 2026.

Investment Approach
Operator Partners explicitly does NOT lead rounds or take board seats. Their stated philosophy is: "If there's not already a lead, we'll help find one." This distinguishes them from traditional VCs and reflects their operational advisory model. They provide deep business guidance rather than governance control.
Speed: They pride themselves on quick decision-making. As stated on their website: "We get to yes - or no - quickly. We understand what it's like to run a company and will respect your time."
Lead Tendency: FOLLOWS (with occasional co-leads)
