Key Takeaways
- • DiligenceSquared, a YC Fall 2025 cohort startup, uses AI-powered voice agents to deliver management consulting-quality M&A research at a fraction of traditional costs, addressing a critical pain point in private equity due diligence workflows.
- • The startup secured a $5 million seed round led by Damir Becirovic's newly formed VC firm Relentless, validating the market opportunity for AI-driven commercial research in M&A.
- • Co-founders Frederik Hansen (formerly Blackstone principal) and Søren Biltoft (seven years at BCG's private equity practice) bring direct institutional credibility, having commissioned and led traditional diligence reports for multi-billion-dollar buyouts.
- • Since launching in October 2025, DiligenceSquared has completed multiple projects for several top-tier PE firms and mid-market funds, demonstrating early market traction within the first five months of operation.
- • The platform reduces friction in the PE deal pipeline by enabling preliminary commercial research before PE firms commit to expensive external advisers—a workflow constraint that historically forces firms to delay consultant engagement until deal certainty is established.
Summary
DiligenceSquared, a newly launched startup from Y Combinator's Fall 2025 cohort, is applying AI voice agents to streamline a historically expensive and time-intensive component of merger-and-acquisition workflows: commercial due diligence research. The startup addresses a structural inefficiency in how private equity firms currently approach early-stage deal evaluation. Traditionally, PE firms defer engagement of expensive external advisers—management consultants from firms such as McKinsey, BCG, and Bain—until deal certainty is high, because consultant fees are unrecovered if transactions fall through. This gatekeeping creates information asymmetries and delays preliminary market and target analysis.
The company's founding team possesses rare institutional credibility within the PE ecosystem. Co-founder Frederik Hansen served as a principal at Blackstone, where he commissioned commercial research reports for multiple billion-dollar acquisitions. Co-founder Søren Biltoft spent seven years leading diligence efforts within BCG's private equity practice, positioning both founders with firsthand experience in the workflows and quality standards DiligenceSquared aims to replicate at lower cost. Rather than engaging human consultants, the platform deploys AI voice agents to conduct customer interviews and gather commercial intelligence on target companies and their markets.
The startup's early momentum has already attracted institutional capital. Damir Becirovic, a former Index Ventures partner, led a $5 million seed round through his newly established venture firm, Relentless. Since DiligenceSquared's October 2025 launch, the company has completed multiple projects for several of the world's largest PE firms and mid-market funds, according to Hansen. This traction within the first five months of operation suggests the market is actively seeking lower-friction alternatives to traditional consultant-led diligence workflows, particularly at preliminary deal stages where research-to-close conversion remains uncertain.
The competitive opportunity is substantial: PE firms currently spend millions on external advisers per transaction cycle. By reducing both cost and time-to-research delivery, DiligenceSquared potentially enables PE firms to conduct preliminary market screening on more potential targets, shifting consultant engagement downstream to later stages where deal probability justifies higher spend.
