Product development for startups

A startup has to validate its market before running out of cash. The product must ship quickly, be solid enough to convince the first customers and be able to evolve without a rewrite six months later. Agencei builds digital products for startups with that balance in mind.

We act as an outsourced technical team or alongside a CTO: MVP scoping, stack selection, web and mobile development, cloud infrastructure and automated deployments, then handover to an internal team once it is in place.

We work with founders at every stage, from validated idea to fundraising, and with funded as well as bootstrapped startups. What matters to us: ship regularly, measure, and do not build what is not yet needed.

Industry challenges

Shipping an MVP quickly

Time is the scarcest resource. You need a scope that is small but convincing, a stack the team masters and a delivery rhythm that puts the product in front of users within weeks.

Preserving runway

Every euro spent on development must serve to learn or to sell. Architecture and hosting choices must avoid unnecessary fixed costs.

Avoiding technical lock-in

A rushed MVP quickly becomes a drag. Without over-engineering, a few foundations (data model, authentication, deployments) must be laid correctly from the start.

No internal technical team

Many founders do not yet have a CTO or developers. They need a partner who makes technical decisions and explains them clearly.

Reassuring investors and first customers

Technical due diligence, security questionnaires, GDPR, availability: the first large customers and investors ask precise questions about how solid the product is.

Hiring and handover

When the internal team arrives, the code, infrastructure and documentation must be easy to take over without depending on the agency.

How we respond

Scoping and MVP in short versions

Scoping workshops to reduce the scope to the essentials, then development in iterations delivered regularly with user feedback between each version.

Proven, productive stack

Next.js or React for the web, React Native for mobile, Node.js or Spring Boot for the API, PostgreSQL, AWS hosting or a managed platform depending on budget. Mainstream choices that make hiring easier later.

Right-sized infrastructure

Simple, low-cost hosting at the start, but described as code and deployed automatically, so you can scale without redoing everything.

Fractional CTO or technical reinforcement

Technical decision-making, trade-offs, participation in conversations with investors and customers, with full transparency about the compromises made.

Preparing for customer and investor requirements

Solid baseline security, GDPR, backups, documentation and monitoring, so you can answer questionnaires without improvising.

Organised handover

Documentation, code review, support during hiring and a progressive handover to the internal team.

Frequently asked questions

How long does it take to build an MVP?

It depends on the scope and integrations. A well-scoped MVP is generally delivered in a few weeks to a few months, in several versions. We deliberately reduce the scope of the first version to put the product in front of users as early as possible.

Can you work with a limited budget?

Yes. We adjust the scope rather than the quality: fewer features, but clean foundations. We also favour managed services and low-cost hosting at the start.

Who owns the code?

You do. The code, infrastructure and documentation live in your repositories and cloud accounts from day one. No dependency on the agency is created.

What happens when we hire a technical team?

We organise the handover: documentation, handover sessions, code review with the newcomers and, if you wish, tapering support for a few weeks.

Can you take over a poorly built MVP?

Yes. We audit the code and infrastructure, fix what is blocking first, then propose either stabilisation or a progressive redesign depending on the state of the existing product.
