Bedrock

About

Bedrock (formally Bedrock Fund Management, LLC) is a technology investment firm founded in late 2017 by Geoff Lewis and Eric Stromberg, with the firm publicly launching and announcing its $122 million debut fund in March 2018 ¹. Lewis previously served as a Partner at Founders Fund, where he led early investments in Lyft and Nubank, and before that co-founded and served as CEO of Topguest, a loyalty software startup ²³. Stromberg was an entrepreneur and angel investor who had worked with Lewis for over a decade ⁴. Stromberg departed Bedrock in 2023, announcing the transition alongside the launch of Bedrock’s fourth fund, and subsequently joined Terrain as a Partner in 2024 ⁵.

The firm grew from $127 million in AUM at founding to over $2 billion by 2025, and its venture funds are described as predominantly top-decile performers ². Bedrock currently invests out of its fourth fund (Bedrock 4, $400M, 2023 vintage) ⁶. The firm maintains offices in Los Angeles and Austin ².

Bedrock operates a concentrated portfolio strategy, making far fewer investments than typical VC firms and reserving significant capital for follow-on financing in its highest-conviction positions ⁷. The firm targets Series A, B, and C rounds with $5M-$50M checks, occasionally participating in seed rounds ⁷. Geoff Lewis sits on the boards of Vercel and Mach Industries and previously served on the boards of Lyft (NASDAQ: LYFT) and Nu Holdings (NYSE: NU) ².

Stated Thesis

Bedrock publicly describes its investment philosophy as being “in search of narrative violations” ⁷. The firm defines a narrative violation as a situation where “the popular story about a company, market, or founder is fundamentally wrong — a disconnect between perception and reality” ⁷. Bedrock states that its core principle is “radical open-mindedness; we constantly question popular narratives in search of hidden truths” ⁷.

The firm’s investment letter articulates: “The best time to invest in a company is when it’s most in violation of a popular narrative” ⁷. Bedrock warns against “narrative mirages” — situations where capital floods categories based on hype rather than fundamentals — citing electric scooter-sharing as an example where over $1 billion was invested across numerous clones despite limited long-term viability ⁷.

Lewis has described himself as a “vibe capitalist,” emphasizing that assessing founders’ qualities and “vibe” is critical to his investment process ⁸. On CNBC in July 2023, Lewis stated that the AI sector was experiencing “a massive A.I. bubble,” even as Bedrock remained a significant OpenAI investor ⁹.

The firm describes its focus areas as AI, defense, infrastructure, and digital assets ².

Inferred Thesis

Based on 35 verified investments from the Gaebler.com database and additional confirmed rounds:

Stage distribution: Bedrock invests across stages but concentrates at Series A and beyond. Of 35 verified investments: 7 Seed (20%), 8 Series A (23%), 6 Series B (17%), 5 Series C (14%), 3 Series D (9%), 2 Series E (6%), and 4 undisclosed/other (11%). Despite claiming to primarily target Series A, the firm’s largest dollar commitments are concentrated in growth-stage follow-on rounds for its highest-conviction portfolio companies (Rippling, Vercel, Flock Safety).

Sector breakdown: Based on 28 unique portfolio companies with verified investments: 6 enterprise software/HR tech (21% — Rippling, Homebase, Workrise/RigUp, Finch API, Check Technologies, Argyle), 4 defense/security tech (14% — Epirus, Mach Industries, Flock Safety, R-Zero), 3 developer tools/infrastructure (11% — Vercel, TensorZero, Radar Labs), 3 food/consumer platforms (11% — Popmenu, APFusion, Dipsea), 2 fintech/AML (7% — First AML, Allocate), 2 media/sports (7% — The Athletic, T1 Entertainment), 2 AI (7% — OpenAI, Durin), and 6 other (21% — including Crayon, Lambda School, SoleSavy, Punch List, Atmos, Rinsed).

Concentrated follow-on strategy: Bedrock’s most distinctive pattern is extreme capital concentration into its top performers. The firm invested over $164 million into Flock Safety across multiple funds and rounds ¹⁰. It wrote a $200 million check to co-lead Rippling’s Series D ¹¹. It participated in four consecutive Vercel rounds (Series B through E) ¹²¹³¹². This “fewer bets, bigger conviction” approach is the clearest signal of the firm’s actual strategy.

Geographic patterns: Portfolio companies are distributed across major US tech hubs with notable presence in Austin, TX (Workrise), Atlanta, GA (Flock Safety), and the San Francisco Bay Area, though without strong geographic concentration.

Founder profile patterns: Bedrock has a stated and demonstrated preference for “narrative violation” founders — those who are underestimated or contrarian. Notable examples include Parker Conrad at Rippling (comeback founder after Zenefits), Ethan Thornton at Mach Industries (MIT dropout, 21 years old when funded), and Garrett Langley at Flock Safety (entering public safety as an outsider) ¹⁰¹¹¹⁴.

Co-investor patterns: Frequent co-investors include Founders Fund, Y Combinator, Sequoia Capital, Kleiner Perkins, Khosla Ventures, and a16z across multiple portfolio companies.

Notable gap: Despite claiming digital assets/Bitcoin as a core focus on their website, the verified portfolio shows only one crypto-adjacent investment (Bitcoin itself, which is an asset rather than a company investment). The firm’s actual portfolio is overwhelmingly enterprise software and defense technology.

In Their Own Words

“The best time to invest in a company is when it’s most in violation of a popular narrative.” — Geoff Lewis, Bedrock investment letter, 2018 ⁷

“Epirus counters the weak assumption baked into standard VC models that the economic and cultural gaps of defense-focused investments are too wide to overcome.” — Geoff Lewis, Epirus Series B press release, December 2020 ²⁰

“People have been doubting the company and underestimating it from the beginning. I don’t think Silicon Valley has ever seen a comeback like this before.” — Geoff Lewis on Rippling and Parker Conrad, Forbes, May 2022 ²⁵

“Vercel is leading a market transition through which we are seeing the majority of value-add in web and cloud application development being delivered at the front end, closest to the user, where true experiences are made and enjoyed.” — Geoff Lewis, Vercel Series C announcement, June 2021 ¹³

What Founders Say

“I’m grateful for these investors’ conviction in Rippling, for the employees that have gotten us to this point, and for our clients, without whom none of this would be possible.” — Parker Conrad, CEO of Rippling, on the Series D round co-led by Bedrock, May 2022 ¹⁷

No other independently sourced founder testimonials found. The Bedrock website references Garrett Langley of Flock Safety saying something during their first meeting in 2018 that prompted Geoff Lewis to immediately want to invest, but the specific quote is redacted in the published account ¹⁰.
