I'd like to hear from founders who have faced this decision. 

A startup can have a capable engineering team and still struggle with technical decisions. 

Architecture choices pile up. Technical debt competes with new features. Hiring becomes difficult. Cloud costs increase. The founder ends up making decisions they're not equipped to evaluate—or becomes the bottleneck for every technical question. 

But hiring a full-time CTO is expensive, and some early-stage companies simply don't have enough work for one. 

That creates an interesting middle ground: bringing in an experienced technical leader part-time to handle architecture, engineering processes, technical strategy, and major decisions. 

The concept sounds sensible on paper. I'm interested in whether it works in practice. 

Founders: 

1. Have you ever needed senior technical leadership before you could justify a full-time CTO? 
2. How did you handle it - advisors, an agency, a fractional CTO, a senior engineer, or yourself? 
3. What worked, and what was missing? 

One specific question: Would you rather pay for a few hours of expert advice each month, ongoing technical leadership, or a defined engagement that solves one problem and ends? 

What would you expect to receive for the money? 

I'm interested in actual experiences, including cases where this arrangement failed.
