Episode One Ventures

Episode 1 Ventures Research Investment Thesis Episode 1 is a London-based early-stage venture capital fund investing exclusively in B2B software companies at the pre-seed and seed stages. Founded in 2010, the firm has developed a clear thesis: back ambitious founders solving real problems that "must exist" and support them intensively through the pre-seed to Series A journey. The fund deliberately avoids B2C and hardware, focusing on defensible software businesses where founders have deep technical or domain expertise. Episode 1 looks for "go-all-in" entrepreneurs — founders willing to quit their day jobs to pursue an ambitious vision. The ideal founder is experienced in their sector, capable of hiring world-class talent, data-driven in their decision making, and has a demonstrated ability to execute at speed. The fund has developed proprietary data-driven sourcing tools that scan signals from LinkedIn, Product Hunt, GitHub, and similar platforms, with approximately one-quarter of recent investments sourced this way. Stage Focus The fund operates strictly at pre-seed and seed stages, typically entering as the first institutional investor. Episode 1 retains pro-rata rights and follows on through Series A but does not usually invest beyond that milestone. The firm's primary objective is helping portfolio companies reach a successful Series A — and it has achieved a 73% Series A conversion rate from its prior fund, a standout metric in early-stage VC. Check Size Episode 1 writes cheques between £250,000 and £2,000,000. For lead investments, they target 10–20% ownership. For follower positions, they take 5–10% ownership. The firm backs approximately 10–12 companies per year. Sector Focus The core focus areas are AI and infrastructure, health and TechBio (computational biology, synthetic biology, quantum computing), developer tools, open source software, and marketplaces. The fund has increasing conviction in AI-native businesses and remains active in regulated sectors like fintech, legaltech, and supply chain. Notable portfolio concentrations include enterprise workflow automation, data infrastructure, security and compliance, and B2B fintech. Geographic Focus Episode 1 invests primarily in UK-based companies, with selective investment in US and European startups that have substantial UK operations or roots. The firm is headquartered at 112–116 New Oxford Street, London WC1A 1HH and is FCA regulated (reference number 604481). Fund History & Status Fund III closed in February 2024 at £76 million ($95M), the firm's largest fund to date. Limited partners include the British Business Bank (via British Patient Capital, which committed £20M), Molten Ventures, and approximately one-third founder-LPs including Alex Chesterman (Zoopla), Aidan Corbett (Webgains), and Aron Gelbard (Bloom & Wild). The fund is actively deploying at a pace of 10–12 investments per year, with 9 investments made in 2025 and at least 1 follow-on in early 2026. Total portfolio spans 65+ active companies and 166+ total investments across all funds. Decision Process Episode 1's process is notably fast — typically within a fortnight of first meeting, and sometimes as quick as two days. The journey involves an initial meeting with one team member, followed by 1–3 additional meetings with remaining investment committee members before a decision is reached. Cold outreach is accepted via the "Submit your Deck" mechanism on their website.
