The firm provides data-driven strategic advisory services to private equity firms, PE-backed companies, hedge funds, investment banks, and corporations, with a track record of 5,000+ completed projects, 3,000+ private equity engagements, and $275B in total advised deal value. Its service lines include commercial due diligence, value creation and growth strategy, exit planning and sell-side positioning, ESG and impact advisory, and data and analytics, organized across seven industry verticals including software and technology, healthcare, business services, industrials, consumer products and retail, education and public sector, and the events ecosystem.

The firm operates a professional services revenue model with project-based engagements typically ranging 4-12 weeks, delivered through direct enterprise field sales to senior executives and deal teams. Its core technology is a proprietary data analytics platform combining data extraction, ingestion, cleaning, and data science with machine learning models, location analytics leveraging granular demographics and mobile foot traffic data, customer analytics for segmentation and lifetime value modeling, and market forecasting tools. This platform is embedded across all service lines and supported by a Client Delivery Network in Colombo, Sri Lanka. Geographic expansion has been a key strategic priority, marked by the 2022 acquisition of London-based AMR International to establish EMEA presence, and reinforced by senior leadership hires across UK and European markets throughout 2025.
