Founders Fund's Former Partner Brian Singerman Shifts to Betting on a New Generation of VCs
Former Founders Fund partner Brian Singerman introduced his new firm GPx on Jack Altman's podcast, stating its goal is to support top emerging fund managers and seek investors who may outperform themselves at their peak.
Singerman worked at Founders Fund for many years, participating in investment discussions for companies like Anduril and Airbnb. The podcast indicates that he is no longer engaged in traditional venture capital partnerships, instead directing capital and judgment towards a new generation of GPs, which includes those establishing new funds, investing independently, or developing unique deal sources.
He opposes using fixed lists to screen founders, emphasizing the search for "spikes," or characteristics of founders who significantly exceed the norm in certain abilities. This approach prioritizes identifying non-average talent rather than seeking entrepreneurs who fit templates based on resumes, education, industry experience, and team completeness; in early investments where extreme results dominate returns, standardized screening can easily miss high-variance individuals who do not conform to conventional profiles.
Singerman attributes Founders Fund's success to concentrated investments and leveraging the firm's own strengths. The podcast mentions that Founders Fund's returns on Airbnb are second only to its investment in Facebook; this indicates that top fund returns are often not accumulated from a large number of average projects, but rather determined by a few long-held, sustainably additive projects with significant exit potential.
He believes the SPV model has become ineffective. SPVs are typically set up by managers around a single project to pool external funds for that transaction; when market liquidity is ample and popular projects are frequently financed, SPVs allow more investors to gain shares, but in an environment of excess capital where quality projects prioritize long-term support and shareholder quality, temporary funding vehicles struggle to replace the brand, post-investment capabilities, and certainty of long-term funds. The core structure of GPx is an incentive mechanism that requires managers to "bet their careers" by taking on long-term funds, clear ownership responsibilities, and personal reputations, thus bearing ongoing consequences for investment decisions. This model does not merely assess whether a project can enter a hot funding round, but evaluates whether managers can establish deal sourcing, screening capabilities, post-investment support, position management, and a complete system for continuously explaining capital allocation to LPs.
In market mechanics, LPs are the buyers of venture capital fund shares, while GPs are the sellers of capital allocation capabilities and project access; GPx supports emerging GPs with capital, who then bet on founding companies. If GPx identifies managers with unique deal sources and concentrated holding discipline, funds will flow through new funds to early high-growth companies; mature large funds, intermediaries relying on SPV arbitrage, and undifferentiated project distribution channels will face pressure. The true scarcity is not the capital itself, but the managers who can secure quality projects, make concentrated judgments, and hold long-term in an environment of excess capital.

Brian Singerman's career shift reflects a continuity akin to Founders Fund. Founded by Peter Thiel, Ken Howery, and Luke Nosek, Founders Fund has long distinguished itself from large funds with a highly concentrated, contrarian investment style aimed at extreme returns. Its early investments in companies like Facebook, SpaceX, Palantir, and Airbnb establish a core fact: total returns in early venture capital often come from a very small number of companies, thus "avoiding all mistakes" may not be more important than "capturing one or two outliers." Singerman's transition from directly selecting projects to selecting GPs effectively shifts the same outlier screening logic up a layer.
In terms of capital flow, traditional VCs raise and allocate funds to startups, whereas GPx first assesses "which investors will consistently find the strongest entrepreneurs" before allocating funds to those investors. LPs invest in GPx, which becomes an early supporter of emerging GPs, who then acquire equity or fund shares in early projects; returns flow back along the chain of "startup exits—fund returns—emerging GPs—GPx—LPs." The bet in this structure is not on a specific valuation or funding round, but on whether the manager possesses repeatable deal sources and long-term decision-making capabilities. It also amplifies the risks of double fees, capital lock-up, and manager selection errors: if GPx selects the wrong GP, LPs will bear two layers of management costs and longer recovery periods.
Historically, Tiger Global changed the private equity market with rapid decision-making and high-valuation financing, while the SoftBank Vision Fund altered the financing scale for late-stage growth companies with massive capital; both demonstrate that capital itself can change prices but does not necessarily create sustained excess returns. On the other hand, the long-term advantages of firms like Sequoia, Benchmark, Founders Fund, and USV stem from the project judgment of a few partners, founder trust, and the ability to provide ongoing support in critical rounds. Singerman's criticism of SPVs targets the market illusion that "obtaining shares in hot projects" equates to "having long-term investment capabilities" during periods of capital abundance.
This pertains to capital concentration. When too much money enters venture capital, ordinary deals and ordinary managers compete for the same batch of projects, leading to higher valuations and thinner terms, while LPs struggle to obtain returns sufficient to compensate for liquidity risks. Ultimately, capital will re-concentrate at both ends: one end consists of a few top GPs with scarce relationships with entrepreneurs, brands, and judgment, while the other end comprises a few companies capable of generating power-law returns. GPx aims to occupy the former before managers are fully priced by the market; its success hinges on its ability to discern true deal sourcing capabilities from mere "pseudo-scarcity" that only achieves one-time allocations during a frenzy.
