Tesonet invests in Nomos Energy to connect home solar, batteries and EVs to Europe's electricity markets

Nomos Energy, a Berlin-based startup, has secured investment from Tesonet to build infrastructure connecting home energy assets to Europe's electricity markets. The company enables hardware and consumer brands to launch energy products without building a utility from scratch. Nomos's platform already powers dynamic electricity products for major brands, including IKEA Germany's first dynamic tariff. The system helps households optimise electricity usage by buying when prices are low, storing energy, and selling back to the grid when more valuable. With a team of eight, Nomos is automating complex aspects of the energy system to prepare for increased adoption of solar panels, batteries, and electric vehicles. The company aims to become the infrastructure layer connecting homes, energy hardware, brands, and markets across Europe's increasingly distributed energy network.

Frame Security emerges from stealth with $50M for awareness and training platform.

Frame Security emerges from stealth with $50M for awareness and training platform. Team8, Index Ventures, Picture Capital, Elad Gil, Cerca Partners, and Tesonet invested in Frame Security. | May 11, 2026 (1:17 PM ET) Frame Security emerged from stealth mode on Monday with $50 million in funding raised for its AI-powered cybersecurity awareness and training platform. The investment came from Team8, Index Ventures, Picture Capital, Elad Gil, Cerca Partners, and Tesonet. US- and Israel-based Frame Security was founded by Tal Shlomo, who serves as the company's CEO, and Sharon Shmueli, who serves as CTO. Shlomo was one of the earliest employees of cloud security giant Wiz, while Shmueli until last year served as the CTO of the global venture group Team8. Frame Security has developed a human risk management platform covering the full security awareness lifecycle, from simulated attacks to employee training to threat triage. Its simulation module generates personalized phishing, voice, and video deepfake scenarios tailored to each employee's role and communication patterns. The platform lets security teams rapidly build and deploy individualized training programs, including content addressing newly emerging attack techniques. A continuous human risk-scoring engine aggregates signals from simulations and employee behavior to provide real-time risk visibility at the individual, team, and organizational levels. Frame also includes a phishing and threat-triage module: when employees report suspicious messages across any communication channel, the platform's AI analyzes and scores them in real time. Frame says its platform is already used by startups and Fortune 500 companies. "We have the right team, the right investment partners, and the right visionary customers working with us on solving a major problem that impacts all enterprises," said CEO Shlomo. "With the investment helping to fuel our growth, we're expanding our engineering team, deepening our frontier AI and cybersecurity research, and accelerating go-to-market across enterprises in the United States and globally." Eduard Kovacs (@EduardKovacs) is senior managing editor at SecurityWeek. He worked as a high school IT teacher before starting a career in journalism in 2011. Eduard holds a bachelor's degree in industrial informatics and a master's degree in computer techniques applied in electrical engineering.
