Demand for sustainable, successful business models is at an all-time high, but funding, launching and scaling a business can be nearly impossible without the right expertise. KI Group solves this problem with its approach to business acceleration.
KI Group is made up of seven subsidiary companies, each with a unique focus. These range from incubation and capital, to intelligent automation and cloud infrastructure. As a result, the KI Group offers companies access to an expansive and integrated range of services. Since it first launched, the company has built an impressive portfolio of forward-facing startups and disruptors, including Pliant, Properly and Carwow.
KI Group operates out of a number of European locations, which has allowed it to successfully tap into promising local markets.
