Announcing our 2017 Global Cleantech 100 Ones to Watch Companies

The new edition of our GCT100 Ones to Watch has just been launched. The list seeks to highlight a group of up-and-coming companies that are catching the eye of leading investors and corporates in the market. The companies made the top 250 in this year’s Global Cleantech 100 program and carry pockets of strong support among the GCT100’s Expert Panel, albeit not having quite enough market support to make the 9th edition of the Global Cleantech 100 list itself (which will be published at our Cleantech Forum San Francisco on January 22, 2018). To qualify for either list, companies must be independent, for-profit cleantech companies that are not listed on any major stock exchange.

A quick look at this year’s companies

This year, 60 companies from 17 countries made the list, with close to half (29) headquartered in North America and a record-high 10 from the United Kingdom. We were happy to see another very diverse selection of companies, comprising well-known O2W alumni such as Cambrian Innovation and Econic Technologies, and newcomers alike. This year’s list spans across 6 different sectors, with the Smart Grid  subsector (under our primary Energy & Power sector) most notably represented by 10 start-ups, including Enervalis, Sympower and Limejump.


Recent investment & deals

2017 has been a busy year for many of our O2W companies. Close to 50 percent of this year’s list has raised capital in the last twelve months. Below are some of the most notable deals:


We’re also pleased to announce that for the first time, a company on the Ones to Watch list has raised capital through an Initial Coin Offering. Described as a “highly disruptive business model” by one of our expert panelists, the Perth-based blockchain start-up Power Ledger completed its ICO on October 6th raising more than $34 million dollars from 15,000 supporters. With one of the first token offerings in the energy space, Power Ledger is hoping to further deploy its peer-to-peer energy trading platform in a number of pilot projects across Australia, New Zealand and India.

What did the experts say?

The panelists’ interpretation and opinions are essential to the creation of the Ones to Watch list and always help shed some light onto what makes, or might unravel, cleantech start-ups over the next 5-10 years. Here is a sneak peek at some of the insights we received for a few of this year’s companies:


While ten of companies from last year’s Ones to Watch list have returned this year, we have also seen others that have been “promoted” and will feature on the upcoming Global Cleantech 100 list. To know who made the big leap, stay tuned for the 2018 GCT100 list, which will be published on January 22nd at our Cleantech Forum in San Francisco.
