+
How does the Design Partner offer work?

You get a team of senior designers every month, for a fixed price. You add your requests to a shared backlog, set the priorities, and we deliver continuously: product, website, brand or Webflow development.

+
Why Rainboow rather than a full-time designer?

Hiring takes months and only covers one profile. With Design Partner, you get several senior specialists from the very first week, for less than a full-time hire, with no probation or notice period.

+
Can you work with our existing team?

Yes. We join your Slack, work in your Figma and project management tools, and fit into your rituals. We work directly with founders, PMs, developers and in-house designers.

+
Who works on our project?

A lead product designer stays your single point of contact from start to finish. Depending on the request, they bring in the team's product designer, web designer, brand designer or Webflow developer.

+
What if we don't have enough work one month?

Pause the subscription. You pick up again when the next project arrives, with the same team and the same context.

+
How do requests work?

You add your requests to the shared board or on Slack. You rank them by priority, we handle the top of the list and keep you posted at every step.

+
How fast do you deliver?

The first deliveries arrive in the very first week. A page or a screen usually takes a few days, a full journey or website several weeks, broken down into regular deliveries.

+
Can we pause or stop the subscription?

Yes, at any time. The pause or stop applies the following month. And if you're not convinced after a week, we refund 75% of your payment.

+
How much does Design Partner cost?

Design Partner starts at €4,000 excl. VAT per month, billed monthly. The price depends on the number of requests in parallel. We define it together during the first call.

+
How do you communicate day to day?

On a shared Slack channel, with Loom videos to present each delivery and a regular check-in to review progress and set priorities.

+
Who owns the work?

You do. The Figma files, Webflow sites and all deliverables belong to you. No lock-in: if you stop, you keep everything.
