Glasswing Ventures

What Glasswing Ventures does

Glasswing Ventures is a Boston-based, founder-led early-stage venture capital firm that invests in visionary entrepreneurs using AI and frontier technology to disrupt enterprise and security markets. Co-founded by Rudina Seseri and Rick Grinnell (both serving as Founder and Managing Partner), the firm concentrates exclusively on AI-native and frontier-tech startups across enterprise SaaS, cybersecurity, AI agents, data infrastructure, quantum computing, and vertical applications such as construction, manufacturing, and pharmaceuticals. Glasswing closed an oversubscribed Fund III at over $200 million in November 2025, with a stated target of funding approximately 25 companies; prior funds produced at least seven disclosed exits between 2021 and 2024 to acquirers including Rapid7, Deloitte, Planful, Avalara, Terminus, VideoAmp, and Magnite.

The firm's differentiator is its 'Building Partners' operating model, in which in-house Partners and Operating Partners (including Ellen Rubin, ex-Netezza and ClearSky Data/AWS) provide portfolio CEOs with C-level expertise across go-to-market, product, engineering, and finance. Glasswing complements this with a 62-member Advisory Council of executives from Google, Microsoft, Salesforce, ServiceNow, Cerebras, Klaviyo, and academic institutions including MIT and Harvard, organized into 'Connect' and 'Protect' councils. The firm has developed three proprietary frameworks — the AI Palette (taxonomy of the AI universe), the Enterprise AI Value Creation Framework (criteria for evaluating AI use cases), and the 5-Stage Agent Autonomy Framework (stages of agent development) — that anchor its diligence process and are published as branded thought-leadership assets, alongside a weekly LinkedIn newsletter ('Rudina's AI Atlas'). A 'Trust Network' connecting portfolio executives reportedly accounts for 4,605 research papers, 332 patents, and 51 companies founded.

Glasswing's revenue model follows standard venture capital economics: management fees (typically 1.5–2.5% annually) on committed or invested capital under management, plus carried interest (typically 20–30%) on successful exits. Capital is raised from institutional limited partners through successive funds; specific LPs and fund terms are not publicly disclosed. Distribution occurs through warm introductions via the Trust Network and Advisory Council, inbound founder flow driven by content marketing and the AI Atlas newsletter, and active participation at conferences including MIT Imagination in Action and RSAC. A long-standing ecosystem partnership with Northeastern University's cooperative education program (formerly via Tyler Fohrman at the IDEA Venture Accelerator) supports early deal flow. The firm is private, founder-controlled, and headquartered at 275 Newbury St, Boston.
