Rule30

rule30.vc · London, UK

“Rule30 uses a fully algorithmic decision engine to identify outlier founders at pre-seed and seed stages across Europe and North America. The fund removes human bias by analyzing founder experience, educational background, network evolution, and career trajectory — excluding names and photos.”

The algorithm ranks founders into top 10%, 3%, and 0.1% tiers. An index-style strategy of 75-85 bets targets ≥3x minimum returns with 97.5% confidence.

Exclusion Criteria

No stated sector exclusions; human gut-feel is their anti-thesis philosophically. Consumer products without strong founder signals are less likely to pass models. No stated geographic restrictions beyond Europe/North America.

Rule30 Research

Overview

Rule30 (stylized "rule30") is a London-based venture capital fund that describes itself as an AI research lab re-engineering how venture capital works. Founded by Damian Cristian, Guy Conway, and Felix Winckler — all of whom previously ran Zero 1, an accelerator — Rule30 is building what it claims is the world's first fully systematic venture strategy. The firm is FCA-authorized in the United Kingdom through its regulatory partner AQ1443 Ltd (trading as "Thema"), which holds FCA registration number 978496.

Investment Thesis

Rule30's core thesis is that traditional venture capital relies too heavily on human bias, pattern matching, and intuition by junior analysts who act as gatekeepers. The co-founders' frustration with this system led them to build a probabilistic decision engine that removes human judgment from the investment decision entirely — no human sits on the investment committee, and humans cannot override a deal if the model says no.

The firm describes its strategy as "algorithmically curated outlier founders" — using deep learning and quantitative methods to identify founders most likely to build billion-dollar businesses. Their decision engine reasons probabilistically about early-stage founders by analyzing founder experience, educational background, network evolution, and career trajectory acceleration — explicitly excluding names and photos to eliminate bias. The algorithm ranks founders into probability tiers: top 10%, top 3%, and top 0.1%.

The fund targets an index-style strategy of 75–85 initial checks with no reserves, designed to reduce the volatility of the asset class and deliver ≥3× minimum returns with 97.5% confidence — rather than relying on lottery-ticket outcomes from a handful of bets.

Stage Focus

Rule30 invests exclusively at the earliest stages: Pre-Seed and Seed. They target founders at the point where traditional VC either overlooks them or relies on gut feel.

Check Size

Typical check sizes range from $100,000 to $300,000 per investment, with the exact amount determined entirely by the probabilistic decision engine, not by human negotiation. This is a hallmark of their systematic approach — check size is algorithmically allocated.

Fund Status

Rule30 is in the process of raising its first institutional fund, targeting $15 million. As of early 2025, the fund had completed a first close and was approximately two-thirds of the way to its target. The fund is actively deploying capital.

Geographic Focus

The firm invests across Europe and North America. The majority of portfolio companies are based in the UK, USA, Germany, Sweden, and France. Headquarters is at The Jellicoe, 5 Beaconsfield St, London, N1C 4EW.

Decision Process

Unlike any traditional fund, Rule30 has no human investment committee. The algorithm makes binary investment decisions; once the model approves, humans engage only for due diligence execution (e.g., legal, compliance). This makes their decision timeline potentially faster than traditional VCs, though the screening process itself is automated.

Lead Tendency

Given their small check sizes ($100-300k) relative to typical round sizes, Rule30 functions primarily as a follower investor, participating in rounds led by others. For example, their investment in Ralio (€2.1M round led by Sure Valley Ventures) and Aiomics (€2M round led by Vorwerk Ventures) confirms this pattern.

Co-investors

Known co-investors include Sure Valley Ventures, Vorwerk Ventures, Seed X, Love Ventures, Plug and Play, Antler, Endurance Ventures, and Campus Fund.

Founder Preferences

The algorithm focuses on the founder profile rather than the idea or market. Key signals include: how a career accelerates relative to peers, depth of domain expertise relative to the company being built, educational background and institutional pedigree, and network evolution. The system can identify "stealth mode" founders on LinkedIn before they've even launched.

Anti-thesis

While Rule30 is multi-sector by design (the algorithm maintains "optimal sector exposure"), they do not express sector-specific exclusions publicly. However, their focus on deep tech and founder quality means consumer products without strong founder signals are less likely to pass their models.

Recent Activity (2025–2026)

  • Stack8s (Dec 2025) — Cloud/Kubernetes infrastructure, UK — most recent known investment
  • Ralio (April 2026) — €2.1M pre-seed, AI agent payments infrastructure, London — Rule30 participated
  • Aiomics (2025) — €2M pre-seed, AI healthcare documentation, Germany — Rule30 participated

The fund was actively deploying as of early 2025 with plans to complete its $15M first fund.
