Seed to Series A founders building AI agents and AI infrastructure. John founded Linea Ventures, a firm custom built for writing Seed-Series A co-investment checks in scaling companies in AI agents and infrastructure as they break out - typically growing from 4x to 10x with $500K to $5M in revenue. He spent the last 10 years primarily at Trinity Ventures, F-Prime, and angel investing, where he returned 4.8x (8x in angels) and backed companies like: • Weights and Biases ($1.8B exit, Series Seed/A) • Applied Intuition ($15B valuation, late) • Betterment ($1.1 valuation, Series B) • Side ($2.4B valuation, Series B) • Squire ($750M valuation, Series Seed/A) The fund focuses on getting proprietary off-cycle deals through its network of partners from seed funds and CEOs, like Applied Intuition and Numeral. LPs and partners include folks from top funds like DFJ, a16z, SV Angel, Index, Matrix, YC, and others.
