Operator Collective is a San Francisco-based B2B venture capital firm with a twist on the traditional model: its limited partners are 250+ working enterprise operators — executives currently building, running and growing tech companies. Started in 2018 by founder and CEO Mallun Yen, the firm raised $51 million for its first fund and $92 million for its second fund, backed by 152 operator LPs plus institutions. The pitch to founders is simple: your investors are the exact decision-makers you need to sell to.

Investment thesis

OpCo's Collective Venture Model® turns the usual VC value-add on its head. Instead of a small partnership advising from the sidelines, portfolio founders get access to a community of hundreds of senior operators across every function — sales, marketing, product, finance — who can open doors to enterprise customers and strategic partners. The model was built deliberately to pull talented operators from diverse backgrounds into venture, and portfolio founders consistently cite the introductions as the firm's single biggest differentiator.

Sectors and stage

Operator Collective invests in early-stage enterprise and B2B companies, largely in the United States. The firm has not publicly disclosed a standard cheque size — ticket details are not publicly disclosed. With a $92 million second fund, expect early-stage rounds where the firm can be a meaningful, hands-on investor rather than a passive follower.

Notable portfolio

The firm's own site showcases founders from across its portfolio, including Ironclad (contract management), Hex (data workspace), Guild Education (workforce upskilling), DataGrail (data privacy), Ramp (corporate spend) and Midi Health (virtual care for women) — a roster that skews toward enterprise software with real operational complexity, exactly where operator LPs add the most value.

Partners

Mallun Yen, founder and CEO, is the public face of the firm — an early team member at RPX and co-founder of SaaStr who built OpCo around the belief that operators, not just founders and VCs, drive company-building. The broader investment team works alongside the 250+ operator LPs who function as the firm's extended partnership.

How to apply for funding from Operator Collective

OpCo does not publish an open application form for founders. The natural route is the website's “Let's connect” sign-up at operatorcollective.com, but in practice the firm sources through its community — a warm introduction from one of its operator LPs or a portfolio founder carries real weight, since the LPs are themselves senior executives at companies you want as customers.

Why it matters for founders

For B2B founders, Operator Collective is a shortcut to enterprise buyers: your cap table becomes a network of potential customers and champions. If your product needs senior-operator sponsorship to get adopted, this is one of the most founder-aligned structures in venture.
