First Found Raising
Backed by a CleanTech US investor
December 2024
First Employee
The Beginning
where a daring idea took shape, our first team member joined the journey, and our products evolved from sketches to reality. With each technical milestone reached, we built momentum, forged our first partnerships, and laid the foundation for what’s next.
The acceleration
Where we strengthened our foundations, built a dedicated team, and advanced our product development. Our partnerships grew stronger, and we began attracting our first client leads. With increasing visibility and access to leading incubators, we moved steadily forward, turning our vision into reality
January 2025
