Episode 812 | The 2025 State of TinySeed

What It Covers

Rob Walling reviews TinySeed's seven-year journey from uncertain 2018 concept to investing in 210+ B2B SaaS companies across four funds totaling $60 million, analyzing current application trends and batch composition patterns.

Key Questions Answered

• •Vertical SaaS advantage: TinySeed shifted focus toward vertical and orthogonal SaaS after data showed stronger exits, lower churn, and better growth compared to horizontal B2B SaaS. Fall 2025 batch contains zero horizontal companies, targeting niches like retail, first responders, and cannabis distribution.
• •AI application surge: Approximately 65% of TinySeed applicants mention AI, but only 30% of funded companies are true AI-first products that couldn't exist three years ago. Many AI startups show catastrophic 10-15% monthly churn despite fast growth, making them unfundable under bootstrapper fundamentals.
• •Vibe coding risk: TinySeed rejects approximately 10% of applicants using AI-generated code without engineer supervision. These companies face ticking time bombs where feature velocity stops and massive regression bugs emerge within 6-18 months, making them unsuitable for long-term investment despite initial momentum.
• •Application growth pattern: TinySeed received 40% more applicants in 2025 than 2024, with fall batches consistently outperforming spring. The fund accepts below 3.5% of applicants (lower than Harvard's acceptance rate) and 80% come from referrals rather than search traffic, creating a defensible moat.
