William Coste

I’m William, a Notion Expert with an obsessive sense of organization, structure, and precision. With a background as an aeronautical stress engineer, I discovered Notion 3 years ago in my personal life, then decided to fully transition professionally as well.

👉 2 years ago, I founded Notionbase (thenotionbase.com), a Notion ecosystem designed to help solopreneurs organize both their life and business. I’ve sold 10,000+ Notion templates, all built with UX/UI principles, scalability and real user needs in mind, for personal productivity or professional operations.

I also educate through a YouTube channel, blog, and online training programs, making advanced Notion systems accessible to everyone.

With real entrepreneurial experience, I deeply understand business challenges such as CRM design, team collaboration, project management, and process optimization.

👉What I can help you with:

-Custom Notion workspace design (from scratch or redesign)

-Audit & optimization of existing Notion systems

-Third-party app integrations & automations

-Workflow design, process optimization, and system architecture

My approach combines engineering logic, business thinking, and user-centric design to create Notion systems that are intuitive, scalable, and genuinely useful.

If you’re looking for a Notion consultant who understands both technology and company needs, I’m here to build a system that truly supports your growth.
