About the company

MapMortar was founded in 2022 as Mortar.io and renamed in 2024, and is based in London. Its three co-founders bring experience in energy systems engineering, commercial real estate and digital twin development.

What do they do?

MapMortar position themselves as the foundational data infrastructure for decarbonising real estate. Their platform builds near-instant virtual models of existing buildings using physics-based modelling, AI and a wide range of datasets, then simulates retrofit options to find the most cost-effective route to net zero.

• What it does: Retrofit simulation and decarbonisation planning across a portfolio.
• Integration: API-first, with models built without needing detailed building-specific data up front.
• Data and reporting: Plan, track and scale a portfolio's path to net zero.

MapMortar suits owners and managers of portfolios with smaller or less sophisticated buildings, where traditional energy audits are hard to justify.
