Technology Vision

The B2B manufacturing industry has a lack of digitisation globally. NowPurchase is building layers of technology to help improve the productivity and profits of the manufacturer. For this we are building the OS (Operating System) that will seamlessly connect factory equipment such as furnaces and spectrometers to our software systems that provide real time optimisations.

The end-game is to use this interconnected system to do great production planning and autonomous procurement of their raw materials. The Heart of NowPurchase will be a marketplace consisting of these smart factories and raw material suppliers.
