Stoneturn Group LLP

Stoneturn Group LLP, a Boston-based litigation consulting and expert witness services firm operating as a prime contractor, delivers financial forensics, damages calculations, and expert testimony to the Department of Justice and Securities and Exchange Commission under full-and-open federal procurements without set-aside designation.

Stoneturn is a for-profit limited liability partnership that has maintained federal contracting eligibility since 2007. The firm operates exclusively as a prime contractor with no subcontractor engagement across its federal portfolio. It competes entirely in the open market, with no SBA certifications or set-aside activity evident in the award record. All fifty-three federal awards in the source span expert witness services and litigative consulting, concentrated across two NAICS categories: All Other Legal Services (42 awards) and Administrative Management and General Management Consulting Services (10 awards).

Customer concentration is acute. The Department of Justice Civil Division accounts for 31 awards (58% of the total) and $4.5 million in combined potential value, followed by the Securities and Exchange Commission with 6 awards and $2.1 million, and the DOJ US Attorney's Offices with 8 awards and $2.1 million. Together, these three customers represent 92% of awards by count and 94% of combined potential value. The two DOJ rankings — Civil Division dominating both volume and dollars — track closely; no tension between frequency and magnitude emerges. Recent representative awards include a $172,134 definitive contract from DOJ Civil Division running through December 31, 2029; a $480,000 time-and-materials purchase order from US Attorney's Offices for litigative consulting (March 2026 through March 2027); and a $477,573 definitive contract from the Securities and Exchange Commission for expert witness services (September 2023, ultimate completion June 2025).

Activity has remained modest but steady. Two to nine awards per fiscal year since 2022, with nine awards in calendar 2026 year-to-date. Five awards (combined potential value $2 million) reach ultimate completion within the next twenty-four months and face recompete risk. All work is performed in Boston, Massachusetts, on time-and-materials or definitive contract structures with no parent-vehicle anchoring — Stoneturn sits on no government-wide IDIQs, GWACs, or agency BPAs.

Service Contract Inventory captures a partial view of Stoneturn's federal work. SCI-reportable invoiced revenue totaled $1.7 million across FY2022–FY2025, with concentration in FY2023 ($1.4 million across 1.7 FTEs). No SCI invoicing appears in FY2024 or FY2025, likely because those fiscal-year contracts had not yet crossed the $150,000 reporting threshold at the time of SCI submission; the award record shows robust contract awards in both years. On SCI-captured work, government-paid hourly rates ran a median $372.13 per hour, with senior labor pricing through $452.40 per hour at the 90th percentile. Stoneturn delivers all services with its own staff — zero sub-hours share across SCI-reportable prime contracts. This self-delivery model, paired with the firm's specialization in high-stakes litigation support requiring deep financial and forensic expertise, positions Stoneturn as a boutique expert witness provider rather than a broad services integrator. The combined potential value across all fifty-three awards stands at $9.8 million, with $9.4 million obligated (96% of potential value).
