What growth does to a product
A product that finds product-market fit doesn't stay the product it was. It grows feature by feature, each one shipped fast and each one reasonable on its own. Two years later, the same product serves several kinds of users and is sold to buyers with tougher requirements. It's built by teams who were never in the room for the original design decisions.
The interface still works. It just stops adding up to one product. That's the problem we're hired to solve, and it's different from early-stage design, where the job is proving the product works at all.
Signs your interface has fallen behind
- Sales demos and support tickets keep explaining the same screens.
- The same action works differently depending on where you are in the product.
- New hires need a walkthrough before they can use what they're building.
- Enterprise requirements like roles, permissions and audit history feel bolted on.
- Every new feature starts a design debate, because there's no pattern to follow.
If three or more of these sound familiar, the issue isn't any single screen.
Fix the system, not the screens
Redesigning screens one at a time doesn't hold at this stage. More people are shipping into the product than ever, and each fix drifts the moment the next feature lands. We start with an audit of what the product has become, decide what to keep, rebuild or retire, and then build the shared components and rules the whole team designs against.
Our design engineers build those components in code alongside your engineers, so the system lives in the shipped product, not in a design file. This matters more now that AI makes generating screens cheap. Producing interfaces is easy. Making a growing set of them feel like one product people trust still takes judgment.
What this looks like in practice
Numeric automates accounting for finance teams. We designed its product from 2022 to 2025, starting before its $28M Series A, and we invested in the company. Numeric has since raised a $51M Series B.
Robust Intelligence builds security for AI models. We designed its brand and product from the earliest days through Cisco's acquisition in 2024, reported at about $400M. Our engineers were embedded with the team the whole time, so what we designed got built as designed. Along the way, the company raised a $30M Series B in December 2021 from Tiger Global and Sequoia.
Cortex is a developer portal. As it moved from startup to enterprise, we rebuilt its brand and product architecture together, so both carried the same decisions. Webflow featured the rebrand, and Cortex raised a $35M Series B and a $60M Series C during the engagement.
Our other growth-stage product work includes Solo.io and ModernFi.
How we work
We take on one new client a month, so the senior people who scope the work are the ones doing it. We design and build product in the same team: our design engineers work with your engineers, so what gets designed gets built as designed. Through Zypsy Capital, we also invest in some of the founders we work with.
