Learn More About Us →One senior advisor, four ways to help — each backed by direct broker-dealer infrastructure through GT Securities, not a rotating team.
Raising the right capital to fuel growth, backed by direct regulatory and compliance experience.
Sell-side, buy-side, and recapitalization guidance, run personally start to finish.
Direct access to institutional, accredited, family office, and strategic investor relationships built over 20+ years.
Financial and operational strategy from someone who has been inside the regulatory machinery of alternative investments, not just around it.
We focus on transactions where structure matters: private credit, growth equity, sponsor-led buyouts, real estate, infrastructure, special situations, and hybrid capital solutions.
Every engagement begins with a clear understanding of the capital stack, investor audience, transaction priorities, and execution roadmap.
When you work with Pythagorean Group, you work directly with Ryan — every mandate, every conversation, every decision. No hand-offs to junior staff, no layers between you and the person actually doing the work.
