What happened
DIG Ventures, the venture capital firm founded by MuleSoft creator Ross Mason, has closed its third fund at €106 million ($120 million). The fund is backed by institutional investors such as Horsley Bridge, Sofina, Granite and a leading U.S. university endowment, as well as entrepreneurial LPs including founders of Slack, Datadog, Nord Security, Cast AI, Supercell and Dash0. DIG plans to deploy the capital into roughly 30 European pre‑seed and seed‑stage startups that address critical AI infrastructure layers – data, identity, compliance and orchestration. The firm intends to lead most rounds and will continue its hands‑on support model, guiding founders from day zero through to their first U.S. customers. Fund III follows a €90 million Fund closed in April 2025 and builds on a portfolio that includes Dash0 (AI‑native observability), Taktile (AI decisioning), CUBE (regtech), Jack & Jill (AI HR), and Nexos.ai (AI orchestration). According to DIG’s internal data, 80 % of Fund II companies raised further institutional capital within two years, and over 90 % entered the U.S. market commercially within a year.

Why it matters
The €106 million fund represents a sizable injection of capital into Europe’s nascent AI infrastructure ecosystem, a segment that underpins the scalability and cost‑effectiveness of downstream AI applications. By targeting early‑stage companies that build the data pipelines, identity management, compliance frameworks and orchestration tools essential for AI workloads, DIG aims to reduce the gap between European technical talent and global market reach. The fund’s backing by both institutional and high‑profile entrepreneurial LPs signals confidence in Europe’s ability to produce defensible, globally competitive AI‑infrastructure firms. Historically, DIG’s portfolio companies have demonstrated strong follow‑on financing and rapid expansion into the U.S., suggesting that Fund III could accelerate the emergence of European “unicorn‑ready” infrastructure startups, diversify the continent’s AI supply chain, and lessen reliance on non‑European providers.
The fund’s focus on AI infrastructure addresses a critical bottleneck in the AI value chain—building the foundational services that enable scalable, cost‑effective AI deployment. By injecting capital into early‑stage European firms, DIG helps diversify the global AI supply chain and reduces dependence on non‑European providers.
The mix of institutional and high‑profile entrepreneurial LPs provides both financial depth and strategic resources, such as market access, mentorship, and potential early‑adopter customers, which can accelerate startup growth and market penetration.
Historical data from DIG’s earlier funds suggest a strong track record of follow‑on financing and rapid international expansion, indicating that Fund III could catalyze the emergence of European AI‑infrastructure unicorns and strengthen the continent’s competitive position in the AI ecosystem.

What to watch next
Investors and industry observers should monitor the first tranche of investments that DIG deploys, particularly startups that secure early traction in AI data lakes, secure identity platforms, and compliance‑as‑a‑service solutions. The performance of these companies in securing follow‑on funding and entering U.S. markets will be a key indicator of the fund’s impact. Additionally, the involvement of high‑profile entrepreneurial LPs may bring strategic partnerships, customer pipelines, and talent networks that could accelerate growth. Finally, the broader European venture ecosystem may respond with increased competition for AI‑infrastructure deals, potentially driving higher valuations and more cross‑border collaborations.
The identity of the first companies receiving capital from Fund III, especially those tackling AI data pipelines, secure identity, and compliance‑as‑a‑service, will be a bellwether for the fund’s strategic direction.
Subsequent fundraising rounds and the ability of these startups to secure U.S. customers will reveal the effectiveness of DIG’s hands‑on support model and the attractiveness of European AI‑infrastructure ventures to global investors.
The response of other European venture firms to DIG’s sizable AI‑infrastructure fund may spur increased competition for deals, potentially raising valuations and accelerating the overall growth of the European AI‑infrastructure sector.
