Tigi

Tigi Solar operates in the renewable energy sector, providing comprehensive heat generation and storage solutions for large-scale industrial and commercial clients. The company was founded in 2008 by Shimon Klier, a polymath with a history of creating successful companies in diverse fields like medical imaging and software. Klier's multidisciplinary background and focus on solving complex technological problems were foundational to Tigi's development.

The firm's core business revolves around decarbonizing thermal energy, which accounts for a significant portion of global energy consumption. Tigi offers integrated systems that include its patented solar thermal collectors, industrial heat pumps, thermal storage units, and cloud-based control services. Its flagship product, the Honeycomb Collector, features a proprietary transparent insulation technology that minimizes heat loss, enabling it to efficiently generate high-temperature heat (up to 100°C) even in cold climates. This technology is designed for applications in sectors such as manufacturing, food and beverage, hospitality, and healthcare.

Tigi employs a "Heat-as-a-Service" (HaaS) business model, which removes the need for clients to make a large upfront capital investment. Instead, Tigi finances, installs, and maintains the heating systems, and customers pay for the heat they consume, enabling immediate cost savings and emission reductions. This service-based approach is central to the company's vision of becoming a distributed renewable-heat utility. Revenue is generated through these long-term energy service contracts.

A significant milestone was the company's initial public offering on the Tel Aviv Stock Exchange (TASE) in March 2021, which raised approximately $10 million to fund growth. In 2024, Tigi made several strategic moves to expand its global footprint, including the acquisition of a 90% stake in SOLID, an experienced Austrian solar-thermal firm, and a partnership with Eren Groupe. The alliance with Eren includes project financing of up to €100 million to scale the HaaS model. These partnerships combine Tigi's advanced technology with SOLID's project execution experience, positioning the company to serve a global pipeline of projects. Together with SOLID, Tigi has implemented over 250 projects in more than 30 countries.
