How we work

Know your numbers

Each stage of the deep-tech journey requires a different kind of TEA support. Select your current stage to see what Lewi can deliver for you.

PRE-SEED

From experimental data to your first investor-ready TEA

We begin with a gap analysis to understand your technology, target scale(s), and available experimental data — then build a credible techno-economic model from the ground up, covering process flow, technical development, cost estimates, and supporting documentation.
