Tacit

AI-driven digital twin for building operations

Overview

Tacit builds an AI-powered digital twin platform for building operations that connects to a building’s existing infrastructure—HVAC, BMS, meters, and IoT sensors—to unify data. Its Agentic AI uses context-aware agents to diagnose, troubleshoot, and autonomously adjust systems, reducing the need for manual intervention and addressing issues like HVAC faults. It provides root-cause analysis, predicts equipment degradation, and continuously optimizes energy use in real time based on occupancy and weather, with audit trails ensuring transparency. The goal is to automate a significant portion of building issues to lower operating expenses, reduce energy waste, and free facilities teams for more strategic work.

Simplify's Take

What believers are saying

  • March 2026 Haatch-led funding supports commercial rollout across the UK and Greece.
  • Tacit reported 10-30% energy savings and 10-100x faster diagnostics in pilots.
  • London hiring for sales and machine learning roles signals active go-to-market expansion.

What critics are saying

  • March 2026's €300k round leaves Tacit undercapitalized for long enterprise sales cycles.
  • Schneider Electric, Johnson Controls, and Siemens own incumbent BMS relationships and distribution.
  • A failed 2026–2027 rollout across UK portfolios kills Tacit before repeatable revenue emerges.

What makes Tacit unique

  • Tacit's UCL research base and Greek founders anchor rare building-operations AI credibility.
  • March 2026 pilots cut UCL building energy 18% and saved £270k annually.
  • Tacit agents diagnose HVAC faults autonomously, with audit trails for every action.
