Notion Capital: Europe's Business-Software Investor, from Pre-Seed to $100M

Notion Capital describes itself as Europe's leading early-stage business software investor, and the numbers on its own site give the claim substance: $1 billion in assets under management and more than 200 companies backed. Founded in London in 2009 by Managing Partner Stephen Chandler together with the two founders of MessageLabs, the email-security company that sold to Symantec for $700 million, Notion invests in what it knows and loves — European business software companies, led at an early stage and held for the long term.

The team is made up largely of former entrepreneurs and operators, and the firm's pitch to founders is explicit: it aims to be the investors its own partners wish they had had. Its stated obsession is increasing a portfolio company's probability of success on the journey from $1 million to $100 million in revenue. To that end it runs the Notion Platform, a value-add programme of events, content, networks and operator expertise, alongside a jobs board and talent network, designed to carry founders through the three stages it calls Start, Build and Scale.

Notion invests across Cloud Computing, Modern Enterprise, Industry OS and Future Finance, historically anchored in SaaS, cloud and fintech, and now increasingly in AI at the application layer rather than model infrastructure. In September 2025 it closed Growth Opps III, a $130 million growth fund — nearly double its predecessor — to tackle Europe's follow-on capital gap, backing both existing portfolio companies and external growth-stage businesses. That vehicle sits alongside Notion Capital V, its €300 million flagship early-stage fund, from which it typically writes €3 million to €10 million tickets at Series A, with cheques that can reach €20 million.

For the very earliest founders there is the Pioneers programme, which writes cheques of around €50,000 into pre-seed and seed-stage software startups at a cadence of roughly one deal a week. The portfolio includes Paddle and GoCardless, trading-API company Upvest, defence-tech startup Kraken, medical software startup Nelly, and Cogna, whose $15 million Series A was led by Notion Capital.
