Situations

Is This You?

If any of these situations sound familiar, we should talk:

No technical co-founder and every architecture decision feels like a coin flip?

Your product is built by an agency and nobody on your side can judge the work?

Have an AI demo that impressed everyone—but still isn't a product you can sell?

Due diligence approaching and not sure how your stack will hold up to scrutiny?

Raising a round and investors keep asking who owns the tech?

Engineering team is shipping slower despite adding more developers?

If you checked even one box, let's talk.

Background

About Me

I'm Ezequiel Actis Grosso, an experienced technology leader with over 25 years of experience in software development. I've worked across the globe—from Buenos Aires to Miami, and from San Francisco to Sydney—helping companies of all sizes succeed, from global corporations to fast-growing startups.

For the past decade, I've partnered with startup and scale-up founders in Latin America and the United States, helping them move fast, find product-market fit, scale their B2B SaaS products, and avoid leaky retention—without the burden of over-engineering and processes that slow them down.

Questions

Frequently Asked Questions

What is a Fractional CTO?

A Fractional CTO is a part-time technology leader who provides strategic guidance and hands-on expertise to businesses that need CTO-level skills but don't need a full-time hire. This allows startups and SMEs to access high-quality leadership in a cost-effective manner.

How is a Fractional CTO different from hiring senior contractors?

Contractors execute tasks you define. A Fractional CTO thinks strategically about your business goals, makes architectural decisions, mentors your team, and takes ownership of outcomes—not just deliverables. I focus on building systems that scale and teams that ship, not just writing code.

What if I need you full-time for 2 months during a critical launch?

Absolutely possible. My engagements are flexible and can scale up or down based on your needs. Many clients start with advisory work, scale up to full-time during critical periods (launches, fundraising, major migrations), then scale back to ongoing strategic guidance.

Do you sign NDAs and IP agreements?

Yes, always. Every engagement includes proper NDAs, IP assignment agreements, and any compliance requirements your business needs. I work with startups handling sensitive data in fintech, healthcare, and enterprise SaaS—confidentiality and security are non-negotiable.

How quickly can you start?

Typically within 1-2 weeks. After our initial consultation, I can often begin strategic work immediately while we finalize contracts. For urgent situations (CTO departure, critical launch), I've started within 48 hours.

What if we're not a fit after the first month?

All engagements are month-to-month with 15-day notice. If I'm not delivering value, you can end the engagement with no long-term commitment. That said, most clients extend beyond the initial engagement because I focus on tangible outcomes from day one.

Do you work with remote teams?

Yes, I specialize in remote and distributed teams. I've managed engineering teams across Argentina, Uruguay, Colombia, Mexico, USA, Australia and Eastern Europe. I'm comfortable with async communication, different time zones, and building strong remote cultures.

What's your experience with GenAI and AI technologies?

I have deep expertise in implementing GenAI solutions, including RAG pipelines, agentic workflows, and AI integration strategies. I help companies leverage AI to automate processes, enhance decision-making, and create innovative customer experiences—without wasting money on POCs that never ship.
