Fractional COO support for B2B SaaS founders who need clearer execution, stronger operating rhythm, and a company that scales beyond founder heroics. Ex-Co-founder & COO at Lightmeter (YC W22).
Work with me
One embedded offer, one focused sprint, and one lighter-touch advisory format.
Embedded · 2–3 days / week
I step into the operating seat, run the rhythm, and help the founder turn priorities into accountable execution.
Project · 4–8 weeks
A fixed-scope sprint to install one critical system fast, usually around GTM, fundraising readiness, or execution infrastructure.
Retainer · monthly
A lighter-touch option for founders who want recurring strategic pressure-testing without a fully embedded engagement.
Operating Context
The common thread is not industry theater. It is helping founder-led companies build the systems, cadence, and accountability to keep moving without chaos.
From early traction to growth, with hands-on work across GTM, ops, and the systems founders need before scale breaks them.
Inside companies where the founder is still too central, helping turn instinct and urgency into operating rhythm and delegation.
Restructuring, cross-functional reset, and other moments when clarity, ownership, and pace matter more than theory.
About
I'm Cesar. My background starts in engineering and operational discipline, then moves into startups where I've worked as a founder, operator, and company builder across GTM, finance, and execution. Most recently I was Co-founder & COO at Lightmeter (YC W22). Today I work with founders who need stronger systems, cleaner execution, and more leverage at the operating layer.
Fit check
The work goes best when there is already momentum, a real bottleneck, and a founder who wants help changing the operating system.
If you're not sure, send a short note anyway. If I'm not the right fit, I can usually point you in a better direction.
