🔥 BERNIE'S HOT TAKE

Glasswing is the rare AI-focused fund that actually knows what they're talking about technically — they use 'unusually granular technical due diligence that differentiates between AI-native companies and GPT wrappers' and built proprietary ML tools to scan research papers and talent signals. Rudina and Rick are genuine AI natives who called the wave early, not AI tourists who pivoted in 2022. Their 'Building Partners' model means they serve as an extension of founding teams, mirroring the leadership functions of a successful company with hands-on technical support. However, with 70+ active companies in their portfolio and Rudina recognized as a top investor, they may be spreading thin — make sure you're getting actual partner attention, not just associate coverage. They have solid exits including Plannuh (Planful), Zylotech (Terminus), and others, proving they can deliver returns, not just hype.

KEY TAKEAWAYS
  • Best for: Technical AI founders who need deep domain expertise, not just capital
  • Watch out for: Portfolio size diluting individual company attention
  • Known for: Genuine AI expertise since 2016, strong cybersecurity network, hands-on support
Investment Thesis

With a focused thesis on early-stage founders using AI and frontier technology to disrupt enterprise and security markets, Glasswing invests in AI-native platforms and products that transform markets. The firm believes that the most value-driving startups will be the ones that are truly AI-native, building products that become deeply woven into enterprise workflows.

Stage & Sector Focus

Glasswing invests primarily at pre-seed ($250K-$500K) and seed ($2.5M typical checks) stages, with selective Series A follow-ons. The fund focuses on AI-native enterprise software, cybersecurity, vertical AI platforms, physical AI, AI-adaptive infrastructure, intelligent enterprise defense, and next-gen compute. They're the first institutional investor in 100% of portfolio companies and first investor in 80% of companies.
