£4.5m seed to automate commercial real estate underwriting with machine learning
This article covers BuiltAI, a London-based AI startup, and its seed funding of £4.5m ($6m) to automate underwriting and financial modelling for commercial real estate. The development aims to replace spreadsheet-driven workflows and speed analysis for investors, lenders and brokers, reducing model risk and shortening decision cycles.
BuiltAI, a London-based AI startup, has raised £4.5m ($6m) in a seed round to automate underwriting and financial modelling for commercial real estate. The platform aims to replace spreadsheet-driven workflows that are slow and error-prone, speeding analysis from weeks to minutes — a change that could alter how investors, lenders and brokers evaluate deals.
Why it matters
Underwriting and financial modelling in commercial real estate remain heavily manual despite the sector’s large software spend. The company cites an annual $26 billion market for real estate software, yet much deal screening still happens in spreadsheets. Research referenced by BuiltAI suggests 88% of financial models contain material errors and that analysing a single deal typically takes at least two weeks. Those frictions translate into missed opportunities and operational drag for firms managing assets and portfolios.
Automating data extraction and model generation has the potential to shorten decision cycles, reduce model risk and enable faster portfolio-level comparisons — practical gains for capital allocators and advisers working across multiple assets.
Inside the product
BuiltAI’s platform applies machine learning to extract building and lease data, aggregating inputs such as lease terms, tenant profiles, valuation points and local market dynamics. The output is detailed financial models produced in minutes rather than days.
Following the seed round, BuiltAI has added an expanded asset management capability that includes full lifecycle modelling, instant portfolio roll-ups and real-time scenario analysis. The company says these features are used by brokers, investors, lenders and valuers to identify optimal business plans, compare scenarios and manage assets more efficiently. In practice, that means portfolio managers can simulate rent, vacancy and capex scenarios quickly and reuse standardised models across assets.
Who are the investors?
Who are the investors?
The £4.5m ($6m) round was led by New York venture capital firm Work-Bench. Participants include Lerer Hippeau, Timber Grove Ventures, Emerald Pine and a group of angel investors and industry figures, among them Jeremy Ford, Managing Partner at Manet Capital.
Investors appear to be backing the thesis that generative and machine-learning tools can be applied to legacy financial processes in property markets to cut error rates and speed underwriting. BuiltAI says the funding will be used to expand operations in the US and UK and to accelerate product development.

Founder perspective
BuiltAI was founded in 2020 by Natan Lempert and Firoz Noordeen. The company positions its technology as a response to longstanding manual practices in property finance.
In the announcement, Natan Lempert, CEO and co-founder at BuiltAI, said:
Real estate is the world’s largest asset class, yet the tools used to evaluate deals have barely changed in forty years. Our AI solution will be transformative for every stage of the property asset lifecycle, from sourcing to acquisition to disposal.
The founders plan to use the new capital to scale the platform and grow presence across the US and UK markets.
The bigger picture
The round sits at the intersection of two trends: growing investor appetite for AI tools that automate domain-specific workflows, and renewed interest in proptech solutions that address operational inefficiencies in commercial real estate. For UK founders, the deal underscores a route to follow-on growth by targeting enterprise customers that face measurable cost and risk from outdated processes.
This funding round also highlights cross-Atlantic investor interest in UK AI companies building infrastructure for traditional industries.
BuiltAI’s progress will be one to watch for investors and operators tracking how AI reshapes underwriting, portfolio management and due diligence across European and US property markets.
