Batisia
2024
Ulysse Alarcos called me while Batisia was at the pre-seed stage. The team was bringing AI to construction, helping major contractors work with technical documents, compare quotes, and prepare cost estimates. The brand, website, and product foundations all needed to come out of the ground. Conveniently, construction was their field.












Direction
I worked with Ulysse and the team to define how the product should be organised, then gave it a design foundation. The identity also needed to keep working after I left, with an image style the team could reproduce and a website they could update themselves.
My contribution
- Drew the logo and created the visual identity and illustration style.
- Built a Midjourney prompt framework and parameters for consistent images the team could generate themselves.
- Designed and built the website in Framer.
- Advised on product strategy and structure, and established the design system and screen foundations.
- Helped design core workflows for comparing quotes and preparing cost estimates, supporting the first deployments with major construction groups.
