Startup brief
AI Computing Infrastructure and Industrial Hardware Lead UK Early-Stage Funding
London deeptech and climate ventures attract fresh capital as Callosum secures $100M for multi-chip AI orchestration and Boldr scales grid-linked thermostats.
Startup
Callosum secured $100 million in seed capital to route AI software across specialized processor chips, cutting compute power expenses for enterprise clients.
BackgroundRunning large AI software models on standard graphics processors is becoming prohibitively expensive for global technology platforms. Specialized chips offer higher efficiency, but software developers lack tools to route computing workloads between different processor architectures.
- Round participants include Plural, DCVC, the UK Sovereign AI Fund, and prominent software industry founders.
- Callosum announced commercial partnerships with alternative hardware producers Cerebras and Rebellions to roll out its inference platform.
- The software automatically breaks complex language processing tasks into sub-routines and routes them to the cheapest available processor chip.
Startup
Twin1 AI raised $20 million to build digital worker clones, deploying administrative software agents across major law firms including Linklaters.
BackgroundWorkplace digital twins ingest employee email streams, document repositories, and calendar records to mimic worker routines. Software agents execute administrative tasks and answer internal queries using the employee's communication style.
- The startup established dual headquarters in London and San Mateo, scaling engineering teams across both UK and US enterprise markets.
- Early legal clients including Linklaters, Orrick, and Dechert deployed the software to process corporate legal research and contract administrative drafts.
- Additional backing was provided by corporate venture arms, including Aramco Ventures, to target financial and energy sector administrative automation.
Startup
London's Embedd raised $2.7 million to eliminate chip programming bottlenecks, using AI agents to accelerate hardware deployment for robotics.
BackgroundProgramming microchips traditionally requires manual low-level coding, creating development bottlenecks for hardware makers. Embedd provides software tools that automatically generate firmware and software drivers for modern silicon chips.
- The capital injection will scale software engineering teams to expand commercial partnerships with global microchip manufacturers.
- Testing demonstrates the platform cuts software integration timelines sixfold for industrial automation and automotive robotics producers.
- Embedd secured an early commercial agreement with Microchip Technology to streamline code deployment for the open-source Zephyr embedded operating system.
Startup
London energy startup Boldr raised $5 million to connect home thermostats directly to electricity grids, unlocking automated peak-demand balancing.
BackgroundHome heating and air conditioning units represent major electricity loads on power grids during peak hours. Connecting residential thermostats to automated grid software allows grid operators to modulate power draw and balance intermittent renewable supply.
- Funding will support commercial launch in North American residential heating markets and back production scaling beyond ductless heat pumps.
- Boldr's platform provides installer contractors with remote diagnostic SaaS tools while enabling homeowners to trade grid balancing capacity.
- Investors backing the round include Ada Ventures, Tetrad Ventures, and HVAC distribution partners across North America.
