capital300

What they fund

• Series A European Tech — Backs European technology companies at the Series A stage, typically in the $5M-$10M range, as seen in the Lokalise round., - Disruptive SaaS — Funds scalable software platforms that address global markets, such as localization and developer tools., - Remote-First Companies — Supports companies with distributed or fully remote operational models, as demonstrated by the Lokalise investment.

Investment thesis

capital300 is the investment arm of startup300, targeting disruptive European technology companies at the Series A stage.

• European Series A focus — Backs high-growth European tech companies, typically at the Series A stage, as the core of its deployment strategy.
• US co-investment leverage — Leverages co-investment partnerships with leading US VC firms to provide portfolio companies with substantial leverage and access to global capital.
• Entrepreneur-led backing — Focuses on companies run by ambitious entrepreneurs who are scaling disruptive technology solutions.

Credibility: The firm's own website and public disclosures describe its mandate to back European tech at Series A and its strategy of co-investing with US VCs to amplify portfolio company growth.

Interconnection: The reliance on US co-investors implies a deployment posture that is opportunistic and dependent on cross-border deal flow, rather than a closed, self-funded European mandate.

Value add

capital300 provides strategic leverage through its co-investment network with leading US VC firms, giving portfolio companies access to global capital and markets.

Fit verdict: Ideal for European Series A companies seeking to expand into the US market or secure follow-on funding from top-tier US investors.

Founder diligence script:

• What specific US VC partners are you currently co-investing with, and how does that relationship translate to deal flow for us?
• Can you share a case study where a US co-investment directly accelerated a portfolio company's Series B or expansion?
• How do you structure your co-investment terms to ensure alignment with US VCs on governance and exit expectations?

Portfolio focus

• Lokalise — A B2B SaaS localization platform founded in 2017 in Riga, Latvia, which raised a $6M Series A in September 2020 with participation from capital300 and Mike Chalfen., - European SaaS & Tech — The portfolio clusters around developer-centric software and digital infrastructure, leveraging the firm's focus on scalable European tech.

Strategic implications

capital300's edge lies in its ability to bridge European tech talent with US capital markets, making it a critical gateway for European startups seeking global scale. The main risk is over-reliance on US co-investors; if US VC sentiment cools, capital300's deployment pace could slow significantly. A signal that would change the read is if capital300 begins leading rounds independently of US partners, indicating a shift toward a more self-sufficient European mandate.

Where they could go further

Expand focus to include Series B follow-ons to reduce dependency on US VCs for later-stage capital, creating a more complete funding lifecycle for portfolio companies., Develop a dedicated US expansion programme for portfolio companies, leveraging co-investor networks to provide structured market entry support beyond capital., Increase transparency around co-investment terms and governance expectations to build stronger founder trust and differentiate from passive co-investors.
