Common Magic Research Document

Investment Thesis

Common Magic is a solo GP fund founded by Sarah Drinkwater, focused on investing in pre-seed and seed-stage startups where the ecosystem or community around the product is the core competitive moat. Operating across Europe and the US, the fund believes that the best companies are built bottom-up through strong communities and that founders who can articulate compelling narratives and build ecosystems will create the most resilient businesses. Sarah brings experience from Google, Protocol Labs, and angel investing, and emphasizes that she won't be the largest check in a round but will be deeply useful through strategic advice, narrative building, and leveraging her extensive network.

Sector Focus

Common Magic invests across multiple sectors with a unifying thesis around community-driven products:

  • Enterprise Software & Developer Tools - Products that build community among technical users
  • Consumer Apps & Social - Community-first social products and platforms
  • EdTech & Media - Educational and content platforms with engaged communities
  • B2B SaaS - Vertical software with strong user communities
  • Specialized verticals - Healthcare (The Lowdown), workplace (Bounti), technical sales, privacy-preserving tools

The fund explicitly seeks "products with community at their core" rather than community-as-feature, meaning the community is the defensible moat and driving force of the business model.

Stage Focus

Common Magic focuses exclusively on early-stage investments:

  • Pre-seed: £100K-£400K for founders with solid ideas and initial traction
  • Seed: £100K-£400K average check size (up to larger amounts for exceptional founders)
  • Occasional early Series A follow-ons with existing portfolio

Sarah positions herself as a first-check investor who expects to be useful beyond capital through strategic input, narrative development, and ecosystem building support.

Check Size

Range: £100K - £400K (approximately $125K - $500K USD)

  • Typical pre-seed check: £100K-£250K
  • Typical seed check: £150K-£400K
  • Target ownership: Not specified, but described as "not the largest check in your round"

Lead Tendency

Common Magic functions as a co-lead or early participant rather than exclusive lead. Sarah emphasizes being useful and hands-on rather than financial dominance, and portfolio companies show her participation alongside other investors (Playfair Capital, Cherry Ventures, Seedcamp, etc.).

  • Fund II in planning stages for 2026 (per Medium post Dec 2024)

Decision Process

Solo GP model with direct decision-making by Sarah Drinkwater. Emphasis on founder fit with community-building philosophy and narrative capability. Quick decision-making with hands-on involvement.

Geographic Focus

Europe and the US, with particular strength in:

  • UK and Europe (London-based operations)
  • US markets
  • Preference for founders who can build cross-geography communities

Founder Preferences

Common Magic explicitly seeks:

  • Founders building products with community at the core (not peripheral)
  • Storytellers who can articulate compelling narratives resonating with hires, customers, investors
  • Builders with ecosystem/bottom-up thinking
  • Technical depth combined with narrative ability
  • Founders focused on freedom (economic, mental, social, spiritual)
  • Companies that build "worlds" - distinct cultures and aligned teams

Anti-thesis: Me-too products, top-down approaches, community-as-feature (rather than core)

Fund Status

Actively deploying from Fund I. Planning Fund II for 2026 with clear thesis. Well-positioned with strong founder testimonials and active deal flow.

Investment Philosophy Summary

Sarah's written thesis emphasizes:

  • "The best companies build worlds"
  • Speed and distribution matter
  • Humans are toolmakers - products should enable active users
  • Privacy should be central to more technologies
  • Bottom-up vs top-down companies more resilient
  • Hardest problems are often social, not technical
  • B2B should have B2C taste and style

This philosophy deeply informs portfolio selection toward community-driven, narrative-rich, bottom-up companies.
