We're here to support your startup at every stage of its journey, from the initial pre-seed phases to the later Series D and beyond. Whether it's short-term, fast-paced initiatives or long-range strategic plans, we'll be by your side, providing the guidance you need. Our product designers deliver custom-tailored design services based on your business objectives.
No — alongside UX/UI design we cover the full product lifecycle: design audits, interaction design, design systems, branding, and development. Our team adapts the scope to what your product actually needs.
Figma is our primary design and collaboration environment, complemented by tools like FigJam, Maze, Lottie, Principle and Protopie for prototyping and validation. For delivery we work closely with engineering in React, Next.js, Astro, and native iOS/Android stacks.
A typical end-to-end product design engagement runs between 6 and 14 weeks, depending on scope and complexity. Smaller audits or landing pages take 1–3 weeks, while full SaaS platforms or design systems span 3–5 months with ongoing iteration.
We work on both fixed-scope projects and monthly design-as-a-service retainers. Fixed engagements start from $8,000; monthly retainers start from $6,500/month. Every proposal is tailored after a free 30-minute discovery call.
