Web development for SaaS and Startups

We build both faces of your SaaS — the site that acquires and the application that retains — on a foundation that survives fast iteration without turning into a mess.

THE CHALLENGE

The challenges of SaaS & Startups

SaaS startups need to reach the market fast without mortgaging the future with technical debt. The software must iterate quickly, scale in multi-tenant and sustain a solid technical story for investors.

  • Speed to market without technical debt
  • Scaling the architecture (multi-tenant)
  • Keeping cloud costs under control
  • Iterating fast with data
  • A solid base to raise investment

How we help you

A software startup has two frontends with opposing goals, and usually neglects one of them. The marketing site needs to be blazing fast and indexable; the application needs to be rich, stateful and session-aware. We build both with React and Next.js sharing a design system and components, so you don't end up with two products that look like they came from different companies and cost twice as much to maintain.

A marketing site that is indexable and fast

Landing pages, blog and product pages rendered on the server, ready to rank from day one instead of being an application Google only half crawls.

Multi-tenant application from the design stage

Session, organisations, roles and plans resolved in the frontend coherently with the backend, so adding a customer is a sign-up rather than a special case.

A design system that prevents the collage

Reusable components and design tokens from the start, because the time to build the system is before you have fourteen variants of the same button.

Built to iterate on data

Product instrumentation and feature flags built in, so you can ship to a percentage of users and decide with metrics instead of opinions.

WHAT YOU GAIN

Web development, results-driven

  • A senior React, Next.js and TypeScript team, with no juniors learning at your expense
  • Web applications that genuinely load fast, measured in Core Web Vitals
  • Accessibility and technical SEO built in from the very first component
  • A design system of your own so the interface grows without becoming a collage
  • A frontend that integrates with your backend and your systems, not an isolated storefront

FAQ

Frequently asked questions

Should the marketing site and the application be the same project?

Almost never the same deployment, but yes the same design system. We separate them so the marketing site can be static and extremely fast while the application can be as dynamic as it needs, sharing components and styles to avoid duplicated maintenance.

How long until a first version is ready?

It depends on scope, but we usually deliver a first complete, usable flow in 6-10 weeks, prioritising the journey that validates your business hypothesis before building out the rest of the interface.

Will the frontend hold up as we grow?

That is the decision we make at the start. Component architecture, state management and rendering strategy are chosen for the product you want in two years, not just for next month's demo.

Custom web build or a template CMS?

If all you need is to publish content and little else, a template CMS is the honest answer and we will say so. Custom development starts to pay off when there is business logic, users with permissions, integrations with your systems, or performance a template cannot give you.

Why React and Next.js?

Because they combine a huge ecosystem with server rendering, which is what lets you have a rich application that is also indexable and fast. Next.js gives us SSR, routing and image optimisation without building our own infrastructure. If your case does not justify it, we will propose something simpler.

Do you only work in Madrid?

We are based in Madrid and work remotely with clients across Spain, Europe and Latin America. If you prefer in-person meetings in Madrid, we do them; if you prefer remote work with short meetings and frequent releases, that works too.

Can you step into an existing web application?

Yes. We audit the code, dependencies and real-world performance to understand what is there, and from that point we stabilise and evolve it in stages, without stopping your operation or defaulting to a rewrite.

Shall we build something that scales, together?

Tell us about your project. We'll get back to you with a concrete plan and a senior team — not a generic quote.
