BayHaus Group

We are Andreas Bayer and Stewart Hauser, seasoned startup veterans with decades of experience leading successful companies in Silicon Valley and beyond. We provide expert technology and finance guidance to help startups achieve their full potential—whether it’s gaining traction, overcoming challenges, or scaling rapidly.

Andreas was Co-Founder & CTO at Beam Solutions (acquired by Jumio), held senior engineering leadership positions at Xoom (where he was instrumental during its IPO and subsequent acquisition by PayPal) and was an early employee at MuleSoft (which went public before being acquired by Salesforce for $6.5B). He also taught computer science at UCSC Extension for over a decade. Stewart led Finance and other functions including Legal and Operations at Chariot (acquired by Ford) and Beam Solutions (acquired by Jumio). He's also a licensed California attorney and has an A.B. cum laude in Economics from Harvard and a JD/MBA from UCLA.

What sets us apart is the power of a cohesive CTO/CFO team. Having worked together on multiple ventures, we deliver excellence across technology and finance—two critical pillars of any startup’s success. Instead of hiring separate fractional executives and navigating potential misalignment, you gain a unified partnership that ensures your tech strategy and financial planning are aligned.

With a proven track record of driving growth, solving complex problems, and leading successful exits, we offer a unique blend of strategic vision and hands-on expertise to help your business thrive.
