BOLDR needs our help to quickly develop a sophisticated minimum viable product that was ready to address the needs of the customers and be ready to scale later on.

BOLDR’s new product, Klima is a plug-and-play device retrofits existing air conditioners and heat pumps, turning them into smart home devices.

BOLDR is on a mission to change the home heating and cooling infrastructure to be fully electric and sustainable.

BOLDR is going after a massive market of 2 billion old air conditioners, improving their efficiency and helping consumers reduce their household carbon footprints, boosting consumer convenience, and empowering them to reduce their energy bills.
