Marcos Ambrosi.Engineering and operations advisor for service businesses

“We’re busy, we’re growing, and somehow it’s harder than ever.”

That’s the ceiling most founders hit at around a 20-person team. I help you build the operations to get past it.

01What I’ve done

As CTO of a product agency, over two years.

4 15
Engineering team, built in under two years
100%+ YoY
Revenue, doubled two years running
20% 45%
Margin, more than doubled

02Where I can help you

What goes wrong

  • You’re the bottleneck. Every real decision still routes through you.
  • Hiring is a guess. You find out months later it was wrong.
  • Wrong people on wrong clients. Your best work and worst churn come from the same mismatch.
  • Margins shrink as revenue grows. More work, more people, less profit per project.
  • Quality slips under the load. Velocity holds, but the standard quietly drops.
  • AI experiments go nowhere. A few pilots, no change to how the work gets done.

What I can help with

  • Build a delivery model that holds quality as you take on more work.
  • Hire the right team and structure it to scale without chaos.
  • Pair the right people with the right clients, on purpose.
  • Fix the margin leaks that show up as you grow.
  • Set scoping and pricing standards so projects stop eating their profit.
  • Build one or two scoped AI workflows with your team, where they actually help.

More than 15 years building apps and leading teams. I scaled one agency’s engineering from 4 to 15, and co-founded another that grew to about 20 people, fully remote. Now I help service businesses run leaner. Based in Montevideo.

04How I work

You built the business by running everything yourself. Now that’s the thing holding it back. Hiring, delivery, margins, and quality all need a senior hand, and you don’t have the bandwidth to give it. That’s the gap I fill. You are buying judgment, not a tool you have to manage. AI is part of how I work, not the headline.

Most fractional help is designed to stay. Mine is designed to leave. One or two scoped builds, your team owns them, I’m out.

Not a fractional CTO parked in your team. Not a one-off training that leaves nothing behind.

05Who this is for

You run an agency, consultancy, or service-SaaS. You are 10 to 50 people. You hit the ceiling of running everything yourself, and you want it fixed with your team, not done to you.

06Engagements

from $2k/mo
Advisory retainer. A thinking partner for the decisions that move your numbers. Hiring, delivery, margins, and where AI fits.
from $8k
Focused engagement. Find the highest-leverage fixes. One area, four weeks, done with depth.
$12–18k
Engagement with a bounded build. A scoped fix built with your team. One or two workflows, AI where it helps, clear exit.
