Charis Siau

I'm a co-founder at Sierra M&A, a boutique sell-side advisory firm focused on helping lower middle market business owners in construction, trades, HVAC, electrical, and specialty services achieve successful exits. I started my career in HSBC Investment Banking. My background spans growth and operations at high-growth companies—including Coinbase, MoonPay, and fintech roles in Zurich and Singapore—which shaped my approach to building teams, scaling operations, and navigating complex transactions. At Sierra M&A, I bring that operational lens to M&A advisory, helping owner-operators understand their options, position their businesses competitively, and negotiate confidently.
