Endorsements

What partners & investors say.

"Brian's financial model for our cold-chain venture was investment-grade from day one. His CPA-K background showed — the ESG metrics, sensitivity analysis, and capital structure were exactly what institutional investors needed to see."

Investment Committee Member East African Impact Fund

"When Brian advised on our solar marketplace, he didn't just build software — he structured the PAYG financing model, calculated credit risk scenarios, and designed the investor reporting dashboard. That's rare expertise."

Managing Director Clean Energy Investment Platform

"Brian's ability to translate sustainability impact into financial metrics is exceptional. He helped us quantify the economic case for our circular economy venture in terms that resonated with both impact investors and commercial lenders."
