Alberto López

FRACTIONAL CTO · WORLDWIDE

15+ years co-founding and scaling SaaS platforms with complex integrations. Today I work with 1-2 companies a year as their part-time external CTO: no extra hires, no roadmap slowdown, no lowering the technical bar. And I design the AI environment that multiplies your team.

  • 6,000+ restaurants
  • ·2,500+ pharmacists
  • ·100+ API integrations
  • ·150+ countries
  • ·15 years

COMPANIES I'VE BUILT AND SCALED

Mozrest
Mediavalue
GOI
ThreeAngular

I know exactly where you are.

If you recognise yourself in one of these three scenarios, let's talk.

01

The technically orphaned founder

Your product moves forward, but the technical decisions are made by whoever should least be making them. Every new integration scares you. You don't know if your stack will survive the next level.

02

A team, but no real senior

You have 3-10 engineers who ship, but no one with architectural instinct. Technical debt starts eating the roadmap. Your CTO left, or you never had one.

03

Scaling 10x without the architecture for it

You've closed a Series A, or you're close. Customers grow, AWS costs grow, timeouts start showing up. You need someone who's done this before, because you can't stop to learn it now.

CASE STUDY · MOZREST

From idea to 6,000+ restaurants across 150 countries.

Mozrest is the neutral middleware that connects a restaurant's critical systems through a single entry point: POS, reservation software and high-traffic channels. Oracle, Lightspeed, SevenRooms, Michelin Guide, Google, Apple Maps and 100+ integrations in production. As co-founder and CTO I built the architecture from scratch, led every critical integration and held 99.9% uptime as the platform expanded to 150 countries.

The technical decisions I made here are the same ones I'll bring to your company.

Three ways to work together.

01

Tech Audit & Roadmap

In-depth technical diagnosis. 3 weeks. Audit of architecture, team, technical debt, cloud costs and opportunities. Deliverable: executive document + 12-month roadmap + prioritised action plan.

The ideal entry point if you're not sure you need an ongoing engagement.

From €5,500
02

Fractional CTO

Your external CTO, one day a week. Tech strategy, team oversight, architecture decisions, technical hiring, communication with board and investors. I also design the team's AI environment and train them to do more with less. I only take 1-2 clients at a time to guarantee real involvement.

The core service. For founders who need direction, not hands.

From €4,500/mo
03

Complex Integration Architecture

A one-off engagement to design and implement critical integrations: APIs across multiple systems, channel managers, webhooks at scale, multi-tenant marketplaces. 100+ integrations in production back the method.

For when the stakes are too high to improvise.

What people who've worked with me say.

Alberto and I have shared many challenges, from Mediavalue to our collaboration on farmaSOLIDARIA. Beyond his ability to turn ideas into reality quickly and effectively, I value his human qualities and the vision we share of creating positive impact and adding value to society. He balances the technical side with the business view, and his approach makes every project move forward with solidity and a clear purpose.
Alberto GómezAlberto GómezCEO · Mediavalue
Alberto and I started working together at The Primos NYC to digitise the whole operation, and from there the idea of creating ThreeAngular was born. His ability to understand the business, spot opportunities and turn them into real technological solutions is impressive. Working with him means moving forward with clarity, focus and results.
Javier Martín De FrutosJavier Martín De FrutosCEO · Threeangular
I worked with Alberto side by side building a video-on-demand platform, and we've collaborated on several projects since. He has a global vision that lets him make technical and business decisions with great judgement, always balancing quality, speed and viability. Working with him is a guarantee of moving in the right direction.
Javier Garcia-GalloJavier Garcia-GalloCEO · Soy Olivia Media Group
I've worked with Alberto on several projects and he's always been a key partner. He combines strategic vision, solid architecture and deep technical command, but what I value most is his ability to simplify and prioritise what matters. With him, technical decisions are always aligned with business goals. More than solving problems, he gets the team to grow and turns technology into a real engine for progress.
