Brand and web design for tech scale-ups
Daasign is a brand and web design agency in Rotterdam for B2B SaaS companies and funded tech scale-ups. Our clients have product-market fit, but their brand, website or product no longer matches where the company is going. We work on brand strategy and positioning, visual identity, websites, UI/UX and product design, design systems and conversion rate optimisation. Our main offer is the Brand Growth System: strategy, identity and a website that converts, built as one system instead of three separate projects. Julien Kreuk founded Daasign in 2024. We have worked for more than 50+ B2B companies, including McKinsey & Company, Famaash and Montblanc. After we redesigned Reptune's platform, its sales grew by 200%. Julien was listed in TNW's T500 Digital Talents from 2022 to 2024 and in the T750 in 2025. We work from CIC Rotterdam, next to Rotterdam Central Station, for clients in Europe and the US, in English and Dutch.

  • Description
    We design the interface of SaaS platforms and web apps: user flows, clickable prototypes, UI and a component library in Figma. We start with a UX audit of what is there now and design for activation and everyday use, not just for how it looks. After we redesigned Reptune's platform, its sales grew by 200%. For Famaash we designed around 100 screens, taking the company from Excel to a full HR platform.

StoryJulien Kreuk started Daasign in 2024 after seeing SaaS teams hire one party for the brand, another for the website and a third for the product. The pieces never fit. We design all three as one system, stay small on purpose and take on two new clients a month.
