The CTO-Shaped Gap in Your Startup
You are making critical technical decisions without technical expertise.
Every week brings technology choices with long-term consequences. You are making these decisions based on Google searches, advice from well-meaning friends, and the persuasive pitches of agencies who want your business. One wrong call compounds: choose the wrong architecture and every feature takes longer to build.
You cannot afford a full-time CTO, and you should not hire one yet.
A senior CTO commands a salary of 150k or more, plus equity and benefits. Before product-market fit, that is an enormous commitment for a role where the demands fluctuate dramatically. Some weeks you need twenty hours of technical leadership. Other weeks you need two.
Investors are asking technical questions you cannot answer.
Due diligence is getting more rigorous. Investors want to understand your architecture, scalability plan, security posture, and technical team strategy. Walking into an investor meeting without credible technical leadership is a disadvantage you cannot afford.
The Source Stream difference
Experienced Leadership on Your Terms
Strategic technical direction
We work with you to define your technology strategy, make architecture decisions, evaluate build-versus-buy trade-offs, and plan your technical roadmap. We are embedded in your decision-making process with the context to make recommendations that fit your specific stage.
Team building and engineering culture
When it is time to hire, we help define roles, write specifications, conduct technical interviews, and onboard new hires. We set up engineering practices -- code review, deployment workflows, documentation standards -- that your team inherits from day one.
Investor and stakeholder confidence
We prepare technical due diligence materials, review your architecture for investor scrutiny, and can join calls to answer technical questions directly. Founders who walk into investor meetings with a credible fractional CTO raise with more confidence and close faster.
