After Salesforce acquired MuleSoft in 2018, Ross Mason founded DIG together with Melissa KlingerMelissa KlingerMelissa Klinger is a British venture capitalist and a general partner at DIG Ventures, a London early-stage venture firm. She was formerly UK sales lead at the enterprise integration software company MuleSoft; after Salesforce acquired MuleSoft, she co-founded DIG Ventures with Ross Mason, and she specializes in helping technical founders build their go-to-market capabilities.Open the full entry, who had been MuleSoft’s UK sales lead; it initially operated as Mason’s family office. Klinger recalled that after selling MuleSoft, Mason saw that early-stage founders in Europe lacked operational support; once the family office showed early success, the two decided to turn it into an institutional fund focused on B2B SaaS, cloud infrastructure, and AI.⁠[1][1][2][2]

Mason said that after leaving MuleSoft he saw an opportunity to come back to Europe and build an operator-led fund, and that they found a strategy for meeting founders earlier and faster than most other funds.⁠[1][1]

On December 24, 2021, DIG Ventures Advisors Limited was incorporated in England as a private limited company, registered as a venture and development capital company, with its registered office on High Road in London; the company operates DIG’s website. It is an appointed representative of Robert Quinn Advisory LLP, which is authorised and regulated by the UK Financial Conduct Authority (FCA); its investment products and services are available only to professional clients and eligible counterparties, not to retail clients.⁠[3][3][3][4][5][5]

In April 2025, DIG announced the close of its second fund at $100 million, which was also its first institutional fund. It invests at the pre-seed and seed stages in B2B SaaS, AI, and cloud infrastructure startups, mainly in Europe but also considering companies in Israel and the U.S., and often writes a startup’s first institutional check.⁠[1][6]

Institutional LPs included The Hillman Company, Granite Capital Management, SofinaSofinaSofina is an investment holding company headquartered in Brussels, Belgium, and listed on Euronext Brussels.

It invests in growth companies in Europe, Asia, and the United States both directly (Sofina Direct) and through commitments to third-party venture and growth funds (Sofina Private Funds), and had a net asset value of about €11.5 billion as of June 30, 2026.Open the full entry, and Grove Street; Datadog founder Olivier Pomel, Instana founder Mirko Novakovic, NordVPN’s Tomas Okmanas, and a number of former MuleSoft executives also invested.⁠[7][1]

At the time, DIG was led by four partners: Mason; Klinger; Rytis VitkauskasRytis VitkauskasRytis Vitkauskas is a Lithuanian, UK-based venture capitalist and entrepreneur and a general partner at DIG Ventures, a London early-stage venture firm. In 2012 he co-founded the event discovery and booking app YPlan in London and served as its CEO; the company was acquired by Time Out Group in 2016. He then invested at Target Global and Lightspeed Venture Partners, where he was the firm’s first partner in London.Open the full entry, founder of YPlan and a former partner at Lightspeed; and Scott Grimes, co-founder of Stackin’ and Uproxx (later acquired by Warner Music). When the fund was announced, it had already invested in about 15 startups, including observability platform Dash0, AI orchestration platform Nexos.ai, and enterprise middleware provider PolyAPI; earlier investments included People.ai, Karat, Bubble, ComplyAdvantage, PlanetScale, Rasa, Taktile, Rossum, Flock, and Prophecy.⁠[1][8][1]

Klinger said the UK is a major focus for DIG, but that it invests across Europe and in select companies from Israel and the U.S.: “We always follow the talent.” Mason said he sees the next big shift as enterprises building their own AI, adding that the foundation layer “isn’t done yet.”⁠[2][2][1][1]

On October 1, 2026, DIG announced the close of its third fund at $120 million to invest in European pre-seed and seed-stage startups building AI-native enterprise software and cloud infrastructure. It plans to back about 30 companies, lead most rounds, and has already begun deploying capital from the new fund. According to the firm, Fund III is 20% larger than Fund II, with individual investments of between $1 million and $5 million.⁠[9][9][9][10][10]

Sofina also invested in Fund II, while Horsley Bridge Partners is a new LP; the fund was oversubscribed and closed after only five months of fundraising.⁠[9][11][10][12][12]

Entrepreneur LPs come from companies including Slack, Datadog, Nord Security, Cast AI, Supercell, and Dash0, among them Olivier Pomel of Datadog, Cal Henderson of Slack, Thomas Dohmke of GitHub and Entire, Tomas Okmanas and Eimantas Sabaliauskas of Nord Security, and Mirko Novakovic of Dash0.⁠[9][11]

The fund’s thesis is that as AI makes software faster and cheaper to build, products become harder to defend, and lasting value will shift to the “control points” other software depends on: foundational layers such as data, identity, compliance, and orchestration. Mason said Europe is not short of technical talent and that the challenge is turning technical advantage into global distribution; DIG helps startups from day zero through to their first U.S. customers.⁠[13][13][14][14][15]

When Fund III was announced, DIG was led by Mason, Klinger, and Vitkauskas; Scott Grimes had stepped down as a director of DIG Ventures Advisors Limited on July 31, 2025.⁠[9][16]

Fund II investments include AI-native observability platform Dash0, decision platform Taktile, regulatory technology company CUBE, AI HR platform Jack & Jill, and AI orchestration platform Nexos.ai. Dash0 reached a $1 billion valuation with a $110 million Series B in March 2026; in June 2026 Taktile raised a $110 million Series C led by Goldman Sachs Alternatives, in which DIG participated.⁠[9][13][13][10]

Realized exits include insurance infrastructure company Flock, acquired by Admiral for $109 million; data infrastructure platform Tower, acquired by MotherDuck; and workload identity platform Cofide, acquired by Keyfactor. Other acquired portfolio companies include Gatsby and OneGraph, both acquired by Netlify, and Makerpad, acquired by Zapier.⁠[9][17][17][17]

According to DIG’s internal data, 80% of Fund II companies raised additional institutional capital within two years of its investment, and more than 90% of commercially launched Fund II companies entered the U.S. market within 12 months; citing Carta data, DIG also says Fund II ranks in the top 10% worldwide among funds of its vintage and size. Vitkauskas said DIG has invested in 13 countries.⁠[9][13][10]

As of October 2026, Ross Mason is founding partner, and Melissa Klinger and Rytis Vitkauskas are general partners; the team also includes head of finance Andrew Baldwin, who previously worked in venture capital at Connect Ventures and Kindred Capital.⁠[18][18][18][18][18]

DIG says its team has built, scaled, and exited multiple B2B software businesses, and that its post-investment support focuses on go-to-market and sales, product mindset, fundraising, and Europe-to-U.S. expansion. It often invests when a startup has little more than a deck and a vision; its process consists of an initial call, a deep dive (go-to-market and technical sessions), and then a decision by the investment committee.⁠[19][19][19][19][19]
