Next Big Thing AG is a Berlin-based IoT company builder that offers a complete framework for the acceleration of IoT ventures. We are an operational VC, technology provider and innovation partner made up of a strong team of business architects, tech experts and experienced founders.

We provide seed funding, engineering expertise, partnerships as well as tailored guidance for our portfolio companies, launching several ventures per year together with brilliant entrepreneurial minds.

The NBT company building model drives all of our ventures to success. The most effective way to drive new IoT ventures is by bringing together entrepreneurs with radical ideas, and industry partners who are struggling to innovate from within, supported by our thriving ecosystem.

Our programmatic approach distills the most valuable ideas, nurturing them, and then supporting them throughout the entire development process, sharing both risks and successes.

IoT Company Builder Structure


We provide an NBT technology stack and expertise to build technology and enable IoT business cases.

Serial Entrepreneurship
We bring the experience and know-how of running successful IoT and high-tech ventures to NBT ventures.

Customer-driven Innovation
We drive innovation with IoT by connecting the dots between customer needs, the technology, and partners.


To create the IoT world of tomorrow by enabling IoT-driven innovation for startups and established companies throughout Europe.


Property, energy, security and healthcare have already shown great potential for IoT to disrupt business as usual.

A tactical business development process has positioned our early ventures to reside in these sectors.

Future growth, however, will drive our exploration in AI, blockchain, commerce and retail, consumer products, transportation and networking. 

We are always open to exploring new markets where we see potential to develop great IoT ventures.


Our investment strategy is strictly focused on creating and financing our own ventures in the IoT field jointly with external investors and industry partners. In addition to providing financial support, we constantly add value to our ventures in an operational capacity in business modeling, customer and product development and UX. Together we strive for rapid business case validation and technical feasibility assessment.

Our main focus is to be an IoT company builder. However, in individual cases, we do consider investment in external startups that are at the conceptual or prototyping stage, where the business model and potential co-operation are particularly promising and meaningful for us. In particular, we are interested in the startups working on both vertical business models, to develop solutions for specific industries as well as horizontal, by creating the technologies that underpin our ventures.
