DealSource Systems is the AI-native origination layer for private equity firms, M&A advisors, and boutique investment banks. We build and operate the infrastructure that puts you in direct conversation with founders, before opportunities reach brokers, auctions, or broad processes. Most firms say they want proprietary deal flow. Few have a system that produces it. We treat origination as infrastructure: thesis-driven market mapping across 16+ data sources and our own web scraping, a 0-100 thesis-fit score on 50+ signals per company, continuous trigger detection for ownership, succession, hiring, funding, and growth, and founder-grade outreach drafted by AI and checked by experienced operators. Run continuously, measured weekly, compounding over time. The result is a steady stream of qualified founder conversations inside your thesis, the off-market opportunities that auctions and intermediaries never surface. One client, a healthcare-focused investment bank, went from 14 founder conversations in the first three weeks to 133 within 90 days, and now averages around 13 new qualified conversations a week. AI does the work that scales. Operators do the work that matters. Most vendors only have one of those, and it shows. DealSource Systems is a Danish Lead Co. company.
