Air Street Capital
AI-first venture capital firm · Air Street Capital
Air Street Capital invests in AI-first companies across vertical software, developer tools, infrastructure, biotech, techbio, security and defense in the US and Europe. They invest from Pre-Seed through Series A, showing stage flexibility similar to Radical Ventures. Their focus on AI-first (not AI-enabled) companies and horizontal scope across multiple industries mirrors Radical's thesis.
Why: Strong match on AI-native thesis and horizontal scope. Less clear on academic pedigree of team versus traditional VC backgrounds. Geographic focus is US/Europe rather than Toronto-anchored.
Conviction Partners
AI-Native Software 3.0 venture firm · Conviction Partners
Conviction Partners is purpose-built for AI-Native 'Software 3.0' companies, believing in the early translation of AI models to products that transform industries. They invest $1-25M checks with stage flexibility, often as first investors. Their thesis that AI represents a paradigm shift beyond traditional software directly parallels Radical's core belief.
Why: Exceptional match on AI-native thesis and 'Software 3.0' framing that echoes Radical's paradigm shift belief. Stage flexibility with large check sizes. Team background unclear from snippets.
Zero Shot Fund
OpenAI alumni-backed AI-native venture fund · Zero Shot Fund
Zero Shot Fund is a $100M fund anchored by OpenAI alumni, backing AI-native founders across robotics, energy, automation, infrastructure, security, and observability. Their edge comes from having built and deployed frontier AI systems themselves. The team's practitioner background (OpenAI builders) and horizontal scope across industries strongly aligns with Radical's approach.
Why: Strong match on AI-native thesis and builder/practitioner team (OpenAI alumni). Horizontal application scope. Less clear on stage flexibility and no Canadian connection.
Differential Ventures
AI-native pre-seed and seed investor · Differential Ventures
Differential Ventures invests in 'visionary architects of dynamic AI systems' for the durable AI economy, positioning themselves as AI-native investors for the AI-native era. They invest pre-seed and seed with $250K-$3M initial checks and follow-on reserves. Their focus on AI systems architecture and stage flexibility aligns well with Radical's approach.
Why: Good match on AI-native thesis and stage flexibility with follow-on capability. Less information on team pedigree and geographic anchor. Application scope appears broad but less explicitly horizontal.
Inertia
AI-native displacement investor · Inertia Ventures
Inertia invests in AI-native companies built to become the core infrastructure of legacy industries, explicitly positioning AI as what displaces legacy systems. Their thesis centers on AI-native companies replacing incumbents. The displacement framing and infrastructure focus aligns with Radical's belief that AI replaces traditional software paradigms.
Why: Strong match on AI-native displacement thesis. Infrastructure focus suggests horizontal scope. Limited information on team background, stage approach, and geography.
nfdg (Nat Friedman & Daniel Gross)
Seed to growth AI investor · nfdg
Nat Friedman and Daniel Gross invest together from seed to growth stage ($1M-$100M checks), sponsor an AI accelerator (aigrant.com), and run the Andromeda Cluster supercomputer for AI startups. Their extreme stage flexibility, builder backgrounds (Friedman ex-GitHub CEO, Gross ex-YC partner), and infrastructure support for AI companies aligns with Radical's approach.
Why: Exceptional stage flexibility and strong builder credentials. AI focus clear but less explicitly 'AI-native replaces software' thesis. No Canadian connection.
MoE Capital
Agentic AI and AI for Science fund · MoE Capital
MoE Capital is an early-stage fund investing in agentic infrastructure and AI for Science, powered by a structured collective of frontier researchers and AI product leaders. Their team composition of frontier researchers directly parallels Radical's academic pioneer approach. Focus on agentic infrastructure suggests deep technical thesis.
Why: Excellent match on team (frontier researchers) and technical depth. More focused on agentic infrastructure and science applications versus broad horizontal scope. Early-stage focused.
Defined Capital
AI Frontier thesis-driven VC · Defined Capital
Defined is a thesis-first venture capital firm investing in the 'AI Frontier' since 2014, empowering founders building across the frontiers of science and compute. Founded by ex-BDC partner Mark Trevitt, with backing from Canadian VCs like Inovia and Band. The Canadian ecosystem connection, early AI investing history, and science/compute focus shows meaningful overlap with Radical's approach.
Why: Strong Canadian connection (ex-BDC, backed by Inovia) and early AI investing history. 'AI Frontier' thesis suggests technical depth. Smaller fund size ($15M USD target) suggests less stage flexibility than Radical.
Merantix Capital
Pre-seed to seed AI-native B2B investor · Merantix Capital
Merantix Capital makes pre-seed and seed investments in visionary AI-native companies, led by established entrepreneurs and researchers. Partners specialize in B2B industry applications with founders who have deep domain expertise. The researcher-led team and AI-native focus aligns with Radical, though more B2B vertical-focused.
Why: Good match on researcher-led team and AI-native thesis. More focused on B2B verticals versus horizontal scope. Early-stage only, less stage flexibility.
