SiliXon builds conversational prompt software that automates the full printed circuit board (PCB) design workflow, including component selection, connection mapping, and generation of manufacturing documentation. The platform aims to reduce multi-week specialist engineering processes to minutes by enabling engineers and non-traditional hardware builders to describe designs in plain language. The Cambridge-founded startup was established in 2024 and operates with a core team of two, planning to expand to around five employees soon. SiliXon competes with startups like Flux and incumbent tools such as Altium Designer and KiCad. The company has raised $1.5 million in its first funding round to ship its first public product iteration and run an open beta targeted for the end of May 2026. Longer term, the startup intends to help bring electronics manufacturing and innovation back to Europe by decoupling some reliance on East Asian supply chains.

Deta is a Berlin- and New York-based startup founded in 2019 that is developing Surf, an AI browser blended with a research notebook akin to Google’s NotebookLM. The beta-stage app allows users to open URLs, PDFs, and YouTube videos, then employ an integrated chatbot to summarize, extract insights, or generate code that can be saved into topic-based notebooks. Surf keeps data local so it can operate offline, and users can reference multiple open tabs as context when querying the AI. The product is currently free, and the team is experimenting with image generation while planning a future premium tier that could add cloud backup, collaboration, and multi-device sync. Deta originally aimed to build a new operating system on an infinite white canvas but sunset that effort in 2023 to focus on an AI browser opportunity. Financially, the company raised a $3.6 million seed round in 2023 and later secured an additional $500,000, bringing total funding to roughly $4.1 million. No revenue or user metrics have been disclosed.

San Francisco–based Mondoo has built what it calls the world’s first Agentic Vulnerability Management platform, using a structured, context-aware AI security model to eliminate—rather than merely catalog—vulnerabilities across cloud, on-prem, SaaS and endpoint environments. Always-on AI agents discover assets, evaluate exploitability, compliance impact and business criticality, then generate pre-tested remediation code through Ansible, Terraform and Intune. The same agents open, track and close ITSM tickets, embedding guardrails into DevOps pipelines so fixes persist and drift is caught automatically. Over the past year the company recorded 7× revenue growth, 4.4× customer growth and exceeded its revenue plan by 62%, with reference accounts such as Deutsche Telekom, a leading U.S. automaker and a Fortune 10 technology company. Customers report a 50% reduction in vulnerabilities and policy violations and faster mean time to remediate. The new capital will speed go-to-market, deepen product capabilities and fund expansion in the U.S. and EMEA while strengthening channel partnerships. Including the latest raise, Mondoo has secured $32.5 million in venture funding to date.

The Martian Lawyers Club (MLC) is building an SDK that uses generative AI to create and run game systems in real time, enabling deeper player personalization by focusing on game mechanics and interactions rather than just assets or narrative. The SDK is designed as a sandbox developers can shape with boundaries and guardrails so generative code snippets produce intended gameplay behavior. MLC plans to ship guardrails and developer controls to prevent the AI from going off the rails and is positioning its product to reduce the need for developers to hand-author thousands of game interactions. To test the technology, the company is building a collectible card game as its first title and has hired its first game designer. With the announced funding, MLC intends to hire a game programmer and a cloud engineer to build out its infrastructure. The company is a spin-off from INSAIT; the INSAIT Foundation holds a small equity stake in MLC.
