Mahtisonni

I am Leo Kokkonen, the designer and entrepreneur behind Mahtisonni. I design, calculate, code and visualize products.

My own product, factory and responsibility for the numbers

I designed my own product, built a factory around it and exported about 80% of production. I have priced products, paid freight bills and reviewed actual costs. I assess how much time the work takes and what it costs.

What I bring to the work

My background covers mechanical design, materials, manufacturing methods, surface treatments and brand identities. I have designed dozens of logos and still draw them by hand. Design and brand projects are agreed individually.

Today I build quote automation, profitability analysis and AI-maintained websites for manufacturing SMEs. I have used AI in Pole’s business since ChatGPT launched. Pole’s systems and this website are also part of my daily work.
