A great team that really listens
"A great team that really listens and fully understood our project.
The result is above our expectations.
Jérémie and Jérôme are extremely available and open to improvements.
We didn't expect to reach this level of execution.
They will also follow our website's progress over the next 6 months. Go for it, it's great."

Ultra-fast work, effective copywriting and a design that converts from the first 24 hours.
Flawless execution.

Frequently asked questions
+Who do you work best with?
With startups and growing companies that need a senior design team without hiring in-house: SaaS, AI, Web3, mobile apps or online services. Our clients usually already have a product, a funding round or a real business stake behind their brand, website or app.
+In practice, what can you help us with?
Branding, websites, landing pages, Product Design and UX/UI, design systems and Webflow development. We often step in when your image or website no longer reflects your company's ambition, or when you need a single team to go from idea to launch.
+Are you a design or a development agency?
Both. Our core expertise is design (strategy, branding, UX/UI, Product Design), and we build the websites ourselves in Webflow. Some clients hire us for design only, others for the whole project, from strategy to launch.
+Can you support us on a product built from scratch?
Yes. We help you scope the project, define user flows, design the experience and deliver development-ready mockups. Depending on your organization, we either run the project end to end or join your existing product team.
+How much does working with Rainboow cost?
Every project is priced individually after a first conversation, based on scope, timeline and the level of support you need. You receive a clear, detailed proposal before any commitment.
+How soon can you start?
Quickly. On the first call, we review your timeline and suggest a concrete start date. If the project is urgent, let us know from the start and we'll plan accordingly.
+How do we work together day to day?
We adapt the pace to your project. Usually: a weekly check-in, regular updates and clear review cycles. On more intense projects, we increase the cadence so decisions get made quickly. At any time, you know what is moving forward, what is ready for review and what comes next.
+Can you work with our in-house team?
Yes, it's actually common. We work hand in hand with founders, product managers, marketers, designers and developers. We can lead design on our own, strengthen your team or support your developers during implementation.
+Can you scale up support as the project grows?
Yes. If the scope changes, we adjust the team and the level of support: product launch, fundraising, website redesign or a more ambitious roadmap. Some clients have been working with us for several years.
+Why work with Rainboow instead of hiring in-house?
Hiring takes time, costs a lot and requires management. A freelancer is ideal for a one-off assignment, but rarely covers strategy, branding, product and website all at once. With Rainboow, you get a senior team accountable for the result, without having to hire each profile.
