ListKit

Overview
ListKit is an all-in-one cold email platform for B2B companies.
977M+ triple-verified contacts, AI-powered lead search, managed inboxes, domains, warmup, and an AI script writing agent, all in one subscription.
Rated 4.8/5 on G2 and trusted by thousands of B2B companies to run high volume cold email campaigns without the technical headache.
They came to us needing a product redesign that matched the ambition of the platform and set a new standard for what a B2B sales tool could look like.
Challenge
B2B SaaS products are notoriously ugly.
Most cold email and sales tools prioritize function over form, resulting in interfaces that feel dated, cluttered, and overwhelming from the first login.
ListKit needed a product that looked as powerful as it actually was, something that felt premium enough to compete with the best designed tools in any category, not just cold email.
Outcome
We spent 3 months redesigning the full product in Figma, with a heavy focus on UX from the very start.
Every flow, every screen, and every interaction was designed to reduce friction and make a complex multi-feature platform feel intuitive and fast.
The design quality was set at a standard above anything else in the cold email space.
The result is the best designed product in its category.
Testimonial
“Marcel and the team delivered an exceptional ListKit platform redesign. Insanely fast and clean! Highly recommend them to founders looking for world-class UI/UX.”
