Founder story
Vestmark was founded in 2001 by financial software innovators Charles Johnson and Dave Blundin in Wakefield, Massachusetts, United States. Having observed that legacy on-premises financial accounting databases were too rigid, disconnected, and slow to handle the emerging shift toward personalized multi-manager portfolios, they engineered an API-first SaaS rebalancing engine. The firm successfully scaled over twenty-five years into an infrastructure backbone, securing long-term wealthtech authority.
