Growth stage
Series C

Primer is the unified payments infrastructure for global commerce, founded by former Braintree and PayPal leaders and trusted by companies like GetYourGuide, Dialpad, and loveholidays. In May 2026 it closed a $100M Series C led by Sofina, bringing total funding to $170M. The site carrying that growth is the one we shipped in March 2024.

Challenge

Primer was scaling faster than its website. Every update went through developers, so campaigns waited, messaging tests stalled, and even small content changes queued behind engineering work that mattered more.

For a payments platform selling to enterprises, that lag shows. The product was moving into new markets and new stories, and the site could not keep pace with the company it represented.

Approach

One decision drove the rest: give marketing full ownership of the site. We designed and rebuilt primer.io in Webflow and migrated the CMS, so the team publishes, tests, and launches pages without touching engineering.

The second call was about the product itself. Payments infrastructure is invisible, so instead of static screenshots we designed how Primer's product appears on the site: in motion, walking a visitor through what the platform does in seconds.

“It was important to find an agency that can be an extension to our team - they have fitted nicely into our ways of working (and vice versa). They don't just agree with everything we ask; they challenge us in a healthy way.”
