The Japanese CarbCut introduction site on a desktop screen. Under a headline about not letting a decarbonization project stop at the concept stage sits copy describing support from project design through PIN and PDD drafting to the work of registration, with buttons to discuss a project or view the product. The login control in the header is marked as not yet open.

The TPN ナビ calculation screen. The scenario picker lists eight presets — manual entry, standard maintenance for very low birth weight, sodium restriction, potassium restriction, hypoglycaemia at a high glucose infusion rate, added lipid emulsion and others — each showing its glucose infusion rate and amino acid figures, above collapsed sections for patient conditions (1500 g, TWI 100, 24 h), nutrition targets and the prescription.

Projects with companies

They appear here as case studies when, and only when, the company has agreed to it.

You do not need to know what to build yet.

A problem, some data or an idea is enough. We start from deciding what to build.
