Daniel Sebastian Gualotuna
Builder|Fractional CMO
Currently one project slot open. As of Jun 4, 2026.
Most founders hire a marketer, a product person, and someone technical. I happen to be all three.
I've built GTM systems for DTC and high-ticket brands, run six-figure monthly ad budgets, led product at a venture studio, shipped AI automations, and yes, also built a couple of apps.
If you have an interesting project or problem, reach out. I'd love to take a look. You can learn more about me and my work below.
