Dune Ventures Research

Overview

Dune Ventures is a New York-based multi-stage venture firm founded in 2020 by David Brillembourg Jr. The firm is structured as a permanent capital vehicle rather than a traditional fund, enabling long-term partnerships with founders without the constraints of typical fund lifecycles. Dune invests globally in a concentrated, highly selective portfolio — backing what they describe as 'outsiders obsessed with the overlooked,' specifically idiosyncratic founders who don't fit the traditional Silicon Valley mold.

Investment Thesis

Dune Ventures describes itself as a multi-stage venture firm backing founders shaping interactive content, social, and technology. The core thesis is built around three pillars: concentration and conviction (investing in a small number of extraordinary founders), long-termism (partnering with founders over multi-decade timelines), and sector focus on interactive entertainment and adjacent technology.

The firm's philosophy is explicitly reactive rather than top-down: 'Our job as investors is not to define the future, it is to back the people who will.' They seek idiosyncratic founders obsessing over atypical ideas and opportunities others overlook. The ideal Dune portfolio company is built around a deeply unconventional founder with a contrarian view of a large opportunity — often in gaming, interactive content, social platforms, Web3, or fintech.

Dune explicitly avoids the traditional SV mold — they are not looking for pedigreed founders from name-brand companies, but rather outsiders with unique obsessions and complementary market perspectives.

Sector Focus

Dune's primary focus has historically been the gaming and interactive entertainment sector, with notable bets across:

  • Video game studios and platforms (Voldex, Mighty Bear Games/GOAT Gaming, Ramen VR, Core Loop, Starform, Millions of Monsters)
  • Gaming social and community tools (Medal, General Intuition, Orbit)
  • Blockchain/Web3 gaming and infrastructure (Polygon/Matic, Mighty Action Heroes, IndiGG, Minteo, Cartridge, Tangle)
  • Adjacent fintech and fraud prevention (The Anti Fraud Co, Minteo)

Over time, the portfolio has evolved to include media, social, and technology plays beyond core gaming. CB Insights classifies Dune as investing across gaming (8 deals), high tech (5), blockchain technology (3), fintech (3), and media & entertainment (3) as of late 2024.

Stage Preferences

Dune nominally has no stage restrictions, operating as a multi-stage permanent capital vehicle. In practice, they prefer to enter at Seed or Series A and follow their winners through subsequent rounds. Their portfolio shows investment activity across Seed ($4M average round), Series A ($8.7M average), Series B ($35M+ rounds), and even Series D (Polygon). The firm's write says: 'Doubling down, and showing support for founders over time, is our model.'

Their stated check size on the homepage is $1–3M lead checks. NFX Signal data puts their range at $100K–$50M with a sweet spot of $3M.

Check Size

  • Website-stated: $1–3M lead checks
  • Range: $100K–$50M depending on stage
  • Sweet spot: $3M (NFX Signal data)

Lead Tendency

Mixed signals. The website explicitly states '$1-3m lead checks,' suggesting they do lead at seed. Historical deals show they co-led Ramen VR's $35M Series B (with Anthos Capital) and led or co-led several seed/Series A rounds. VCSheet classifies them as not typically leading. Given the website copy, they appear willing to lead at early stages, particularly seed, though they also participate in larger syndicated rounds.

Fund Structure

Unlike most VC firms, Dune Ventures is structured as a permanent capital vehicle investing off a large balance sheet rather than a traditional closed-end fund with a fixed lifecycle. This structure allows them to invest across any time horizon without fund lifecycle pressure — aligning with their stated belief that 'the most ambitious founders of the generation are building companies over longer periods of time' (citing Unity, Epic, and Roblox as examples of long-duration companies). No external LPs, no fund raise cycles.

Decision Process

Dune is a Solo GP operation led exclusively by David Brillembourg Jr. David is a Forbes 30 Under 30 Class of 2023 investor (gaming/VC category), educated at NYU Stern School of Business, who founded the firm in 2020. As a solo GP, David makes all investment decisions. He is the sole point of contact for deal sourcing, evaluation, and portfolio support.

Recent Activity

  • October 2025: General Intuition (Seed) — latest known investment per CB Insights
  • January 2025: GOAT Gaming / Mighty Bear Games (Strategic round, $4M)
  • November 2024: Starform (Series B follow-on)
  • July 2024: Cartridge (Series A, $7.5M, gaming/StarkNet)
  • January 2023: Voldex (Series A, co-invested with a16z)

Tracxn shows no new first-time investments in 2025–2026 (only follow-ons), suggesting the firm is selectively deploying. Their last high-activity vintage was 2021–2022 (14+ investments across two years).

David frequently mentions backing people he personally believes in, emphasizing the interpersonal relationship with founders over pattern-matching.
