Spotlight Interview: MapMortar

In our latest Spotlight Interview, we spoke with Josephine Bromley, COO & CoFounder at MapMortar. Josephine shares how the real estate sector is evolving from spreadsheet-led compliance exercises to intelligent, investment-driven decarbonisation strategies, what a truly 'net zero' portfolio looks like and their plans for growth."A truly net zero-ready portfolio is one where transition risk is fully embedded into the financial strategy.It is characterised by a clear understanding of which assets remain viable through the 2027 and 2030 regulatory milestones."

Q1-MapMortar has seen significant growth in recent times, what lead to the founding of MapMortar and how has your journey been so far?

MapMortar was founded in 2022 following a period of frustration regarding how real estate engineering and retrofit delivery were being handled. The founding team, including Ranjeet, Jo, and Ruggiero, observed that sustainability and decarbonisation were consistently treated as independent cost items instead of being integrated into core asset management strategies.

The journey has been defined by a shift away from compliance exercises driven by spreadsheets toward investment strategies grounded in implementation reality.
We developed a proprietary physics-based building modelling engine combined with an AI-driven data layer, with support from University College London, and since then we have grown to serve major market players like Places for London and British Land.The company now acts as the infrastructure layer for the energy transition within the real estate sector.

Q2- What role does your RECAP (real estate capital planning) system play in improving capital allocation decision-making for asset managers and landlords?

The Real Estate Capital Planning (RECAP) system serves as the analytical engine that drives strategic decision making and capital allocation.
It replaces the slow and fragmented outcomes associated with traditional excel sheets by providing a real time digital simulation across an entire portfolio. It embeds engineering grade physics and financial risk into buy, hold, and exit decisions to ensure that capital is deployed with precision.
We're solving the critical pain point of protecting asset value in a volatile market, RECAP allows managers to determine the feasibility of investments with unprecedented speed and accuracy.

Q3- How do you help clients balance sustainability goals with financial performance and CAPEX planning?

We help our clients balance sustainability goals with financial performance by moving away from passive data and focusing on risk adjusted performance.
The system uses agentic first logic to identify where capital should be deployed first to defend IRRs and NAVs.
This approach ensures that retrofit sequencing is done strategically and proactively rather than reactively.
By using an autonomous digital strategist, called RetroAgent to handle complex modelling, we enable asset managers and landlords to make accurate capital allocation decisions much faster than they otherwise would.

Q4- In your view, what does a truly “net zero-ready” portfolio look like?

A truly net zero-ready portfolio is one where transition risk is fully embedded into the financial strategy.
It is characterised by a clear understanding of which assets remain viable through the 2027 and 2030 regulatory milestones. In this view, a resilient portfolio is not just about meeting targets but about avoiding the brown discount where assets lose value due to a lack of transition and physical risk mitigation.
A net zero-ready portfolio uses dynamic risk modelling to proactively manage exposure to tightening regulations, physical climate risks, and refinancing hurdles.
It represents a move from uncertainty to precise capital allocation.

Q5- Lastly looking ahead, what’s next for MapMortar in terms of growth and innovation?

The future is cantered on building the data infrastructure that powers the entire retrofit value chain. The company is intentionally moving away from the typical SaaS model to become an Outcome-as-a-Service organisation.
This involves the use of autonomous digital agents that function as multidisciplinary team members to synthesise engineering, financial, and regulatory inputs in real time.
Over the next decade, innovation will focus on helping landlords understand their assets physically and model risk dynamically.
We aim to be the industry standard for capital planning under climate pressure by elevating human expertise through autonomous execution.
