Investor Profile: Atlantic Bridge - Thesis, Cheque Size & How to Apply

Atlantic Bridge is a Dublin-headquartered growth equity firm founded in 2004 that backs deep technology companies across Europe and the United States. Its distinctive pitch is the Bridge Model: using an international platform to scale European technology companies into the US and Chinese markets, the two markets it regards as decisive for technology companies.

Thesis

Atlantic Bridge invests in deep technology with genuine global potential and then works to internationalise it. Rather than simply funding growth, the firm positions itself as the bridge between European innovation and the world's largest technology markets, drawing on offices and networks in Dublin, London, Palo Alto and beyond. Its model has, in its own words, delivered top-decile returns for investors, with realisations totalling more than €1.7 billion across its earlier funds.

Sectors & Stages

Atlantic Bridge focuses on deep technology: semiconductors, artificial intelligence, enterprise software, hardware and life sciences, including medical devices. It invests from early stage through growth equity, and through its university funds it also backs companies at the commercialisation stage, when world-class research is being turned into a business. Its portfolio spans quantum computing, surgical devices, climate technology and business software.

Fund & Cheque Size

Atlantic Bridge III, launched in 2016, is a €140 million growth equity fund focused on taking companies with proven business models to the next level in international markets. Its University Bridge Fund, created with Trinity College Dublin and University College Dublin, is a €60 million fund for early-stage companies built from Irish university research. Its later Atlantic Bridge IV fund, a 2019-vintage growth fund, is reported at $317 million. Cheque sizes for its current funds are not publicly disclosed.

Notable Portfolio

Scaled portfolio companies cited by Atlantic Bridge include Movidius, FieldAware, PolarLake, Swrve and Metaio. More recent investments include Dublin medical device company CroíValve, whose DUO Coaptation Valve system treats tricuspid regurgitation; quantum computing company Equal1; AI safety company Secondmind; Swiss AI validation company LatticeFlow AI; Swedish semiconductor company SweGaN; surgical imaging company LUMA Vision; and medical device company ProVerum.

Partners & Programs

Atlantic Bridge was founded by Brian Long, Elaine Coughlan, Gerry Maguire and Kevin Dillon, with Brian Long serving as Managing Partner. Its flagship programme is the University Bridge Fund, run with Trinity College Dublin and University College Dublin to commercialise research from all Irish third-level institutions, backing software, hardware, engineering, physical sciences, life sciences and agri-food spinouts. It also co-manages Summit Bridge Capital, a US$100 million China Ireland Technology Fund, with Chinese partner West Summit Capital. No published credits or perks programme for founders was found.

How to apply for funding

Founders can contact Atlantic Bridge through its website, and university researchers should also explore the University Bridge Fund route via their institution's commercialisation office. The firm looks for deep technology with a solid, exciting business model and a credible plan to scale into the US or Chinese markets — founders should come prepared to discuss international go-to-market, not just the technology.
