## About

William Greenblatt established the office in 2015. Its capital originates from the sale of Sterling Talent Solutions, the background-screening business he founded in 1975. The firm maintains headquarters in New York and invests exclusively in North America. Montague Street Private Partners executes the private-equity strategy. It targets control investments in fragmented business-services sectors that generate recurring revenue and positive cash flow. The office commits family capital directly through SPVs and co-investments rather than third-party funds. Confirmed holdings include Precision Reporters, Action Reporting, Fairygodboss, openDoctor, Field Control Analytics, Remote Legal, and Andover National Corporation. All positions sit in the United States. The team consists of five named professionals. William Greenblatt serves as Chairman; his sons Jake and Brandon hold portfolio and operational roles. Adjacent philanthropic commitments include board service at NYU Langone Health, Success Academy Charter Schools, and Cardozo Law School. No additional offices or club memberships beyond these boards appear in public records. The office differs from conventional private-equity vehicles by retaining permanent capital and operating companies without exit timelines. This mandate allows direct operational involvement and multi-decade holding periods.
