The Post Oak Group, a Houston-based investment bank, today announced its official launch as a comprehensive middle-market advisory platform offering integrated capital markets and M&A services to companies ranging from emerging growth businesses to established middle-market enterprises.

Houston, TX December 19, 2025 --(PR.com)-- Founded by seasoned investment banking professionals, The Post Oak Group addresses a critical gap in the market: the need for institutional-grade advisory services delivered with boutique attention throughout a company's entire growth trajectory. The firm's integrated platform supports transactions from early-stage seed and growth capital raises through later-stage liquidity events and exits.

"We've built a platform that provides continuity, strategic alignment, and institutional expertise at every inflection point in a company's lifecycle."
