Overview
Tacit develops an AI-powered digital twin platform for real estate buildings that automates and optimizes operations by connecting to HVAC, BMS, meters and IoT sensors to form a unified view. Its Agentic AI uses context-aware agents to diagnose, troubleshoot, and autonomously adjust systems to reduce manual intervention. It provides root-cause analysis, predictive maintenance, and energy optimization based on real-time data like occupancy and weather, aiming to lower OpEx and energy waste. Audit trails log automated actions and reasoning to ensure compliance, with the goal of freeing facilities teams for more strategic work.

What believers are saying
- March 2026 pre-seed from Haatch and Corallia funded commercial rollout.
- Pilot sites in London and Europe showed 10-30% energy savings.
- 2026 launch targets enterprise deployments in UK and Greece with commercial team growth.
What critics are saying
- Trane, Siemens, Schneider, and Johnson Controls already bundle AI into entrenched building stacks.
- Tacit still lacks broad deployment, making pilots easy for incumbents to copy.
- Failure to reach £1M ARR within three years kills the company.
What makes Tacit unique
- UCL spinout with seven grants and a decade of building-performance research.
- Semantic knowledge graph unifies BMS, meters, work orders, and engineer know-how.
- Multi-agent system acts autonomously while logging every decision for auditability.
