How this fintech startup generated 5 enterprise leads in the week after web launch
Driving real startup traction with a new web presence
Founded out of Madrid, Centinel builds an AI accounting engine for modern finance teams.
Its platform plugs into your ERP and learns the G/L, chart structure and business rules to draft complete, audit-proof entries, ready for approval.
The problem of Centinel
Centinel needed to solve a perception gap that was creating friction in sales and stalling growth. Storytelling and visuals weren't connecting with what enterprise buyers actually cared about.
Here's what we found:
A previous agency had delivered an unusable output that the team rebuilt themselves a week later, so trust was low.
The website was serving an old ICP and carried a high bounce rate. The visuals weren't giving them the robustness they were looking for.
They had a lot of ideas for the product with no clear visual way to execute them. They needed an innovation partner to work with, week to week.
Engineering was leading the product journey with no clear direction on the user experience.
From a site that lagged to a presence that leads
One visual standard across brand and product, built to describe where the company was heading.
Centinel's founders wanted something specific: a presence that catches an investor's eye the way top-tier YC companies do. We built the brand system to communicate: strong presence, maturity and consistency, with visual line that carries the same weight in a pitch deck as it does on the homepage.
The existing site had real structural problems. Nothing was reusable. Components looked different from page to page. None of it read as trustworthy. We rebuilt the site around the actual offer and how Centinel solves its core problem for CFOs so it spoke directly to the audience it needed to convince.
Based on the research we detect adoption barrier: finance teams were used to solving problems in Excel, or with general-purpose AI tools. We built a platform for low friction instead with seven modules, each solving one specific pain accountants and CFOs already had.
The impact
Across every channel, Centinel started reading as senior, polished enough to get noticed inside the SF startup circles it was trying to reach. The founders got a sales tool. The website ran in the background of every sales call, telling the same story they were telling out loud.
The design system's built to scale. Centinel's own engineers kept shipping new layouts at the same level. That's what a fast-moving startup like Centinel actually needed, without a design team to do it.
Closing the gap moved the numbers fast. In the first month live, traffic climbed 392% with no ad spend, and the site the founders once avoided sending became the one they open outbound with.
The website started speaking to the right ICP through technical storytelling. In the first month after launch, Centinel booked 5 enterprise leads for product demos.
