Three European and US DeepTech Startups Raise Fresh Funding Across Solar, Credit and Noise Control

Cognitive Credit (London)

Cognitive Credit, a London-based provider of corporate credit data, analytics and AI technology, has raised a 35.73 million euro (40 million dollar) strategic growth investment, EU-Startups reported. The round was led by global growth equity firm Summit Partners, with continued participation from existing investor ETFS Capital. It follows an 8.93 million euro (10 million dollar) Series B led by ETFS Capital in September 2024 and a 7.17 million euro (6 million pound) Series A led by Fitch Ventures in November 2021.

Summit Partners Partner Chris Bon, who has joined Cognitive Credit's board, said high-quality data at speed and scale is critical to powering AI workflows that credit professionals increasingly rely on for high-stakes decisions, according to EU-Startups. The company was founded in 2017 by Robert Slater. Its platform combines verified data, advanced analytics and domain-specialist generative AI for the credit research workflow. EU-Startups cited the OECD's Global Debt Report 2026 in noting that corporate credit markets saw nearly 12.5 trillion euros (14 trillion dollars) raised in 2025.

Optivolt (US)

Optivolt has raised 32 million dollars in Series A financing to advance its intelligent solar technology, Ventureburn reported. VXI Capital led the round, with participation from RA Capital, Valo Ventures and Atlas Innovate, bringing the company's total capital raised to 42 million dollars.

Founded by Rohit Kalyanpur, Optivolt develops power electronics intended to boost the output of solar panels and reduce energy losses that occur in real-world conditions. The company plans to use the funding to expand manufacturing and reach more solar markets, with ambitions spanning residential installations to utility-scale projects. According to Ventureburn, Optivolt has shipped more than 20,000 panels using its Power Balancer technology, which targets output losses caused by shade, dirt or degradation affecting individual cells.
