--- title: Bill Gates' climate tech portfolio --- Plus: Nordic climate tech's debt in numbers | Latest deals | View in browser Morning reader,   Last week, we reported that Bill Gates had flown to Berlin to discuss Germany’s climate tech future. At the event, which was attended by politicians, startup founders and state banks, Gates spoke about his experience funding capital-intensive climate technologies in the US.    Gates’ approach to climate tech is three-fold. There’s the Breakthrough Energy Fellows programme, a two-year initiative to help early-stage founders develop their technologies. Then there’s Breakthrough Energy Ventures, a VC fund. Last, there’s Breakthrough Energy Catalyst, an investment platform which funds large demonstration projects and FOAKs (first-of-a-kind projects). The VC arm, Breakthrough Energy Ventures, raised a new $555m fund in January. Scroll on to see the European companies it has backed.   Elsewhere, I was at Cleantech Capital Day in Helsinki this week, where there was lots of discussion about how different parts of the capital stack can edge closer together to fill in the funding gaps for infrastructure startups. Commercial banks are yet to get comfortable with the emerging asset class — and there were questions on whether state banks can step further into the fold. In today’s newsletter, we’ve got the latest stats on debt financing in the Nordics — which saw a major ramp up in Q1.   But!

ADVERTISEMENT Nordic climate tech needs €15bn   A new report compiled by Tesi, a Finland-based investment company, estimates the Nordic climate tech ecosystem needs to raise €15bn over the next five years. The figure is based on the number of companies at each growth stage and historical funding rounds.   The same study also estimates Nordic VC and PE investors with climate tech mandates have €6bn in their coffers to invest over the next five years.   “Few Nordic investors have the resources to finance the largest growth leaps, so the role of European and global investors are particularly essential, especially in later funding rounds,” says Jakob Sandell, research manager at Tesi.   Elsewhere, a new study from Cleantech for Nordics shows the increasingly pivotal role debt financing is taking in the region. In the first quarter of 2024, the total amount of debt secured by climate companies in the Nordics surpassed the figure for the entirety of 2023. B2B SaaS: Here’s how to avoid the chopping block   In a challenging economic climate, where companies are scrutinizing their spend, SaaS tools are often the first to be cut back. Our latest report offers invaluable insights from Europe’s software masters on not just surviving, but thriving, amidst the current market lull.  Download it here German battery recycling startup Cylib raised €55m in a Series A funding round led by European climate tech VC World Fund and Porsche Ventures, the venture arm of the sports car manufacturer. Bosch Ventures, Germany’s €1bn deeptech and climate tech fund (DTCF) and NRW.Venture participated along with existing investors Vsquared Ventures, Speedinvest and 10x Founders. The all-equity deal will enable Cylib — which recycles lithium-ion batteries — to start scaling its technology at an already-secured brownfield industrial facility in Germany, near Aachen, where the company is based. Enspired, a Vienna-based company which helps owners of energy storage assets — such as battery facilities — to sell on their power capacity, has secured a €25.5m Series B round. The round shows that as more renewables are hooked up to the electricity grid, investors are cottoning on to the opportunity around the energy storage market.    Zurich-based 8inks, which has developed coating technology for lithium-ion battery production to reduce battery production costs, raised €3m in pre-seed funding. Founderful led the round and was joined by investors including Übermorgen Ventures. Berlin-based hexafarms, which develops software for indoor commercial food production, raised €1.3m in pre-seed funding.
