About This Fund
Glasswing Ventures III is a $200 million venture capital fund raised by Boston-based Glasswing Ventures to back pre-seed and seed-stage companies in artificial intelligence, enterprise security, and frontier technology. The fund reached its final close on November 10, 2025, significantly oversubscribed and representing the largest fund in Glasswing Ventures' history since the firm's founding in 2018 by Managing Partners Rudina Seseri and Rick Grinnell.
The investment thesis centers on backing founders building AI-native companies that transform enterprise B2B markets and redefine cybersecurity infrastructure. Glasswing has identified six priority technology areas for Fund III: vertical AI, physical AI, AI-adaptive infrastructure, intelligent enterprise defense, collaborative intelligence platforms, and next-generation compute. The fund targets approximately 25 startup companies over its investment period, with Glasswing serving as the first institutional investor—as it has done in over 90 percent of its prior 70 investments. The 14-person investment team is supported by a 62-member advisory council of technical and industry operators.
Glasswing Ventures' track record spans 70 investments since 2018, with portfolio companies collectively raising more than $650 million in follow-on capital. The firm has consistently led pre-seed and seed rounds in enterprise AI and cybersecurity, including companies that have reached Series B and beyond. Fund III builds on two prior funds with a deepened focus on AI-native architecture at the enterprise layer, positioning Glasswing as one of the defining early-stage investors in the enterprise AI and intelligent security market.
