Flexin CTO · CTO as a Service

We restructure your technology team around AI

We take technical leadership of your company and change how your team builds — processes, tooling and culture — so it ships more with AI. Not a dev shop, not rented developers: we reorganise the technology you already have.

Fractional CTO

Senior technical leadership for your company, without a full-time hire.

We own your roadmap, architecture and technical decisions, and lead your existing team toward outcomes — on a monthly retainer, not per hour.

AI adoption, end to end

We put AI to work inside your team and your product.

We map where AI actually moves the needle, set up copilots, pipelines and automations, and train your team to use them. Measurable output, not hype.

Team & process restructuring

Reorganise how your tech team works to become AI-native.

We redesign roles, workflows and delivery so your team ships faster with AI — and we hand it over running, with or without us.

Our mission

Restore the role of the technical leader and put them in front of distributed teams, combining senior experience, practical AI and outcome-driven processes.

Our vision

Become the methodology chosen by founders and CTOs who need squads with real technical leadership, integrating seamlessly with Scrum or Kanban.

Flexin was born in 2020, when remote work exposed the gap between average squads and those guided by technical leaders. Since then we have designed a methodology that empowers senior leadership to make decisions, organise the roadmap and guarantee impactful deliveries across LatAm, Europe and the Middle East.

Depending on scope, an MVP takes 4 to 10 weeks. We define measurable goals, weekly sprints and continuous releases to validate everything with real users.

I handpick senior developers, train them in Flexin Agile and they embed into your operation with weekly deliveries and reports. You can add a full squad or specific profiles.

Yes. I take over technical leadership, organise processes, ceremonies and communication without stopping current releases. I work with your internal leaders to raise the team’s level.

I work with idea-stage startups, growing scale-ups and established companies that need to accelerate specific projects or professionalise execution.

We work with JavaScript/TypeScript, Node.js, React, Next.js, Vue and Angular; mobile with Swift, Kotlin and Flutter; backend with Python, Go, Java, C#, Rust and modern PHP; GraphQL/REST APIs, microservices and Kafka queues. We integrate Web3/Blockchain with Solidity, databases such as PostgreSQL, MySQL, Mongo and Redis, plus datalakes in BigQuery or Redshift. We deploy on AWS, Azure, GCP and hybrid clouds, always with CI/CD, automated testing and AI applied to QA and documentation.

We schedule a call, define scope and metrics, send a clear proposal and in less than two weeks we start with kickoff, onboarding and a delivery plan.
