northbridge.com North Bridge Venture Partners one of Boston's most storied venture capital firms, founded in 1994 by Bill Geary, Doug Kingsley, Ed Anderson, Mike Pehl, and Richard D'Amore — ~$3.5B under management across 8 funds, ~200+ investments, 100+ exits, and 14 unicorns. Legendary portfolio: Demandware (sold to Salesforce for $2.8B), Starent Networks ($2.9B to Cisco), Proto Labs (IPO), Couchbase ($1.5B to Haveli, 2025), Quora, Salsify, Acquia ($1B to Vista), Actifio (to Google), Paydiant (to PayPal). Its growth-equity arm split off in 2018 as Guidepost Growth Equity ($1.1B+ AUM). Today the fund is in harvest mode — no new deals since 2021–2022, small remaining team, minimal website. May 2026: ransomware group DragonForce claimed to have stolen 22.9GB of internal files (unconfirmed by the firm). For startups seeking capital it's not an active option; for portfolio/LP diligence or the breach, it remains relevant.

Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
