Working with Grafit feels like having an exceptional design team that’s part of our company. They understand our metrics, they move at our speed, and they consistently deliver quality that reflect our product and vision. When you’re growing fast, this kind of partnership is invaluable.
Fryderyk Wiatrowski
Co-founder & CEO at Jace.ai
Jace.ai had already built a working product. An AI email agent with strong retention. Their team was sharp, their product vision was clear, and they had the data to back every decision they made.
But when you scale fast in a competitive market, speed and design quality are the first things to slip. That is where we came in to build on what was already working as their growth design partner.
Scaling meant more pages, more ads, more channels. Every one of them had to be fast to ship, on brand, and built to convert. That’s the challange jace.ai faced, and they needed a partner who could match it.


Fast-growing companies hit the same wall. You need design quality to compete, but you cannot afford to slow down. Hiring an in-house team takes months of recruiting, onboarding, and process. By the time you ship, the market has moved.
Jace.ai chose the growth design partner model because it delivers:
The result: jace.ai moves like a startup while shipping work that rivals companies ten times their size.
We started with our startup-specific Product Marketing Canvas framework to nail down exactly who Jace.ai served and why they'd choose it over alternatives. Deep user objection analysis helped us understand every barrier preventing conversions.
Complete brand refresh to create a modern, trustworthy identity that screams "established market leader" rather than "beta testing." Every visual element was designed to build immediate credibility and trust.
Designed the hero section with crystal-clear value proposition and 3-second solution animation. Created product demonstrations that make complex AI capabilities instantly understandable. Integrated trust-building elements throughout the user journey.
Simplified pricing structure, added compelling testimonials, showcased security features, and highlighted fast setup to remove every possible objection. Built comparison sections showing exactly what tools Jace replaces and why switching makes sense. Developed high-converting ad creatives and marketing materials to support ongoing paid acquisition campaigns.
The right stack removes bottlenecks and gives your team the freedom they need to move fast.
