Prolo raises £4.2m led by Triple Point Ventures with Concrete VC
This article covers Prolo, a supply chain startup, which has raised £4.2m in a growth funding round to commercialise an AI-driven procurement service for small and medium-sized construction contractors. The funding will support expansion of Prolo's product and technology to reduce procurement friction, improve price visibility and extend flexible credit terms for SME contractors in the UK construction sector.
Prolo, a supply chain startup, has raised £4.2 million in a growth funding round to commercialise an AI-driven procurement service aimed at small and medium construction contractors. The funding will help the company expand its product footprint in a sector where fragmented supply chains and tight margins routinely squeeze smaller firms.
Why it matters
UK construction is under pressure: small contractors have faced material price volatility, lengthening payment cycles and chronic inefficiencies that eat into already thin margins. The Chartered Institute of Building estimates that supply chain disruptions and manual workflows contribute to roughly 40% of projects suffering delays averaging five months. A procurement layer that reduces friction, provides price visibility and eases cashflow pressure could materially affect how many smaller contractors bid for and deliver work.
Inside the product
Prolo positions itself as an outsourced, AI-enabled procurement team for site managers. Users can place orders and queries via WhatsApp, email or phone. The platform scans a network of more than 185 suppliers to surface trade rates on bulk materials and specialist plant hire that are typically negotiated by larger contractors.
It also offers flexible credit terms of up to 90 days, which Prolo says helps smaller contractors take on larger projects without immediate capital outlay. The company argues automation and supplier aggregation reduce administrative overheads and pricing opacity that have long disadvantaged smaller buyers.
Who are the investors?
Prolo’s £4.2 million round is being deployed to scale customer acquisition and accelerate product and technology rollout.
Lead and participating investors in the round include Triple Point Ventures, a16z Scout Fund, Anamcara Capital, Concrete VC, Foundation Ventures, Haatch, Koro Capital, Love Ventures and Portfolio Ventures. Concrete VC is known for early bets in construction and property technology, while Haatch and Foundation Ventures focus on early-stage UK tech companies.
In the announcement, Sam Stone, Investor at Triple Point Ventures, said:
Construction companies are vital to the UK economy, and they will play an increasingly important role as the country looks to accelerate the delivery of new housing and infrastructure. Procurement remains one of the most manual and margin-sensitive parts of running a construction business, and Prolo has a huge opportunity to change that. By using AI to help firms automate procurement, find the right products at the best prices, and improve their margins, Prolo is solving a real and urgent problem for the industry. We're excited to be backing James, a repeat founder with a strong track record, as he builds a category-defining business in construction procurement.

Founder perspective
The company is led by James Morris-Manuel, who previously founded Virtual Walkthrough and later served as EMEA managing director at Matterport, where he helped establish the London regional headquarters after Virtual Walkthrough’s acquisition. Speaking about the problem Prolo aims to solve, Morris-Manuel said:
In the announcement, James Morris-Manuel, Founder & CEO at Prolo, said:
For decades, SME contractors have been penalised by a lack of price transparency and inefficient ordering, often paying a premium simply because they lack the time and purchasing power of the Tier-1 giants. Through scaling Virtual Walkthrough and my time at Matterport, we learned how to build robust tech that solves very real, very painful operational bottlenecks for the built environment. With Prolo, we are entirely shifting the dynamic of construction supply chains. The demand we are seeing right out of the gate is phenomenal.
The bigger picture
The deal underscores continued investor interest in firms that aim to digitise back-office processes in construction and supply chains. For UK policy makers seeking faster delivery of housing and infrastructure, improved procurement flows and better access to credit for smaller contractors could remove practical bottlenecks to project delivery.
If Prolo can combine supplier reach, credit terms and automation at scale, it may become a useful example of how technology can redistribute purchasing power in construction. The outcome will be watched closely by supply chain investors and operators across the UK and Europe as firms tackle similar productivity and cashflow challenges.
