Sound Ventures

Investor in Formation Bio (venture round and Series C), OpenAI, AND Anthropic; the only known investor spanning both sides of the AI competitive divide while holding a stake in a company that partners commercially with one side. Launched a $240 million AI fund concentrated on foundation model companies.

Sound Ventures is a Los Angeles–based venture capital firm co-founded in 2015 by actor Ashton Kutcher and talent manager Guy Oseary, with Effie Epstein (formerly Marsh global strategy and iHeartMedia SVP) joining as a third General Partner in 2017. Kutcher previously co-founded A-Grade Investments in 2010 with Oseary and supermarket magnate Ron Burkle, turning $30 million into $250 million through early bets on Airbnb, Uber, and Spotify [1]. Sound Ventures manages over $1 billion in assets across funds, with a portfolio of 300+ companies including Affirm (NASDAQ: AFRM), Duolingo (NASDAQ: DUOL), GitLab (NASDAQ: GTLB), SentinelOne (NYSE: S), Flexport, and Hugging Face [2]. Oseary’s background is entertainment management — he managed Madonna and U2 and founded Maverick at Live Nation before transitioning to venture capital.

Formation Bio Investment

Sound Ventures invested in TrialSpark’s October 2018 venture round alongside Thrive Capital, Sequoia Capital, Spark Capital, Felicis Ventures, TQ Ventures, and Cherubic Ventures. Sound Ventures remained through the Series C (September 2021), the Altman-led round that took TrialSpark’s valuation to $1 billion. Sound Ventures is not listed on the Series D investor sheet, suggesting it may have exited or held steady without participating in the June 2024 round [3].

The venture round was the first significant expansion of Formation Bio’s investor base beyond the seed-stage Sequoia/Thrive pair. Sound Ventures entered alongside two other entertainment-adjacent funds (TQ Ventures, founded by Scooter Braun) and Google-network capital (Wesley Chan at Felicis). This round brought celebrity VC visibility, broad media relationships, and cross-sector deal flow access that institutional firms like Sequoia and Thrive could not provide on their own.

The AI Triple Position

In May 2023, Sound Ventures closed an oversubscribed $240 million AI fund with a stated strategy of investing in “category-defining artificial intelligence businesses at the foundation model layer.” The fund’s first three investments were OpenAI, Anthropic, and StabilityAI [4]. The fund planned to invest in only approximately six companies total — a deliberately concentrated bet on the premise that “the biggest winners in AI will be few and massive” [5]. Kutcher described AI as “potentially the most significant technology we will experience since the advent of the internet.” Oseary added that Sound expects AI to play an “impactful role in everything we do — including entertainment, an industry we know well” [6].

This creates a position that is unique across the entire Formation Bio capitalization table. Sound Ventures holds concurrent stakes in:

OpenAI — which co-developed the Muse AI tool with Formation Bio and Sanofi
Anthropic — OpenAI’s primary competitor, founded by former OpenAI employees Dario and Daniela Amodei
Formation Bio — which partners commercially with OpenAI through the Muse collaboration

No other known investor in the Formation Bio capitalization table holds positions on both sides of the OpenAI/Anthropic competitive divide while simultaneously holding a stake in a company that does business with one side. Spark Capital has a similar cross-competitive position (Formation Bio venture round + Anthropic Series C lead), but Sound Ventures’ holding is more direct — a GP-led, dedicated AI fund with named positions in all three entities.

(Anthropic conflict flag: Sound Ventures’ presence in OpenAI, Anthropic, AND Formation Bio creates the most concentrated version of the cross-competitive conflict documented in this investigation. Information about OpenAI’s commercial partnership strategy with Formation Bio could theoretically flow to a firm that also holds an Anthropic position. Whether information barriers exist within Sound Ventures between its OpenAI and Anthropic relationships is unknown.)

The Venture Round Investor Network

Sound Ventures, Felicis Ventures (Wesley Chan), and TQ Ventures (Scooter Braun) all entered Formation Bio at the same October 2018 venture round. Taken together, these three firms reveal the architecture of Formation Bio’s early capital base:

Sound Ventures connects Formation Bio to the AI foundation model investor community through concurrent positions in OpenAI, Anthropic, and StabilityAI — the same firm that holds a stake in a company that partners commercially with OpenAI.

Wesley Chan / FPV connects Formation Bio to the Google network (Google Ventures founding partner, Google Analytics creator, Sergey Brin colleague), the pharmaceutical exit pathway (iPerian → Bristol-Myers Squibb acquisition), and the Canva/Flexport/Plaid tier of decacorn investing. Chan followed TrialSpark across three different fund vehicles (Felicis venture round → Felicis Series C → FPV Series D), demonstrating personal conviction beyond any single fund’s thesis.

TQ Ventures connects Formation Bio to entertainment-industry capital (Braun) and the health/wellness venture space (Noom, Kindbody).

All three entered at the same round — the moment when Formation Bio’s capital base expanded from institutional-only (Sequoia/Thrive) to cross-sector. By the Series C in September 2021, when Altman led the round to $1 billion, the investor base already included celebrity VCs, Google alumni, entertainment moguls, and institutional funds — a network broad enough to provide deal flow, reputational cover, regulatory access, and media relationships across every sector that matters to the biotech stack.

Why This Matters

Sound Ventures’ relevance to the Formation Bio investigation is not as healthcare specialists — Kutcher and Oseary are entertainment figures, not pharmaceutical experts. Their relevance is as network connectors whose rolodex spans entertainment, technology, and politics, providing deal flow access and reputational cover across sectors that institutional VCs cannot reach. Kutcher’s concurrent involvement with both OpenAI and Formation Bio connects the pharmaceutical investment to OpenAI’s broader investor community through a single GP.

More specifically, the $240 million AI fund’s concentrated six-company strategy means that Sound Ventures’ partners have direct GP-level relationships with leadership at OpenAI, Anthropic, and StabilityAI simultaneously. When OpenAI enters a commercial partnership with Formation Bio (Muse, November 2024), a Sound Ventures GP can evaluate that deal’s implications for their OpenAI position, their Formation Bio position, and their Anthropic position — all from the same office. Whether that evaluation serves as neutral oversight or as a mechanism for cross-pollinating competitive intelligence is the structural question.
