VerbaFlo, a UK-based conversational AI platform built for residential real estate, has raised $7 million (£5.2 million) in a seed round led by London proptech VC Pi Labs.
The round also drew in Haatch, Navigate Ventures, Old College Capital (the University of Edinburgh's in-house venture fund), and a number of global family offices. Total funding for the company now stands at approximately $9 million, after a prior $2 million raise in late 2024.
What VerbaFlo Does
Founded in October 2024 by Sayantan Biswas, Abhishek Garg, VP Singh, and Dan Smith, VerbaFlo builds AI agents that handle communication and operational workflows for property owners and operators. The platform sits across email, web chat, WhatsApp, and phone, and connects directly with existing property management and CRM systems.
Instead of replacing a landlord or operator's current tech stack, VerbaFlo acts as an intelligent layer on top of it. Specialised AI agents manage different parts of the property lifecycle: qualifying leads, scheduling viewings, chasing follow-ups, handling maintenance requests, and supporting renewals. As of this announcement, the platform runs across more than 200,000 residential units globally and is adding around 30,000 units per month. It supports conversations in over 200 languages.
Customers include Homes for Students, Moda Living, Fusion Students, Housing Hand, and Downing, among 40-plus others.
What the Founders Said
Sayantan Biswas, founder of VerbaFlo, put the problem plainly: "Real estate is one of the largest industries in the world, yet much of its revenue still depends on fragmented communication across channels. We built VerbaFlo to address this by creating a purpose-built vertical AI platform for residential real estate that integrates with the systems operators already use."
Faisal Butt, founder and managing partner at Pi Labs, added that the team has built an AI-native platform using agentic AI to run leasing and property management, with measurable outcomes: faster leasing, less operational friction, and a better experience for residents.
Pi Labs has made over 90 investments across 15 countries since 2015 and delivered 17 exits. This deal sits within Pi Labs Fund IV, the firm's latest vehicle focused on applied, vertical AI in the built environment.
Why This Matters for UK Founders
The £5.2 million raise is a useful data point for founders building vertical AI products in industries that have traditionally moved slowly on tech adoption. A few things stand out.
VerbaFlo was founded in October 2024 and has already crossed 200,000 units. That growth rate, paired with a credible lead investor like Pi Labs, is what unlocked this seed round at speed. If you are building a vertical AI product, traction in a concentrated, repeatable use case matters more than broad ambition.
The investor mix is also worth noting. Old College Capital, the University of Edinburgh's venture arm, joined alongside global family offices. University-affiliated funds are an underused source of early capital for UK founders, particularly those with academic or institutional connections. They tend to move faster than traditional VCs and are less brand-sensitive.
Finally, the focus on conversational AI across multiple channels (voice, chat, email, text) rather than a single chatbot reflects where enterprise AI adoption actually is in 2026. Operators do not want another tool. They want one intelligent layer that connects everything they already have. That is a product lesson worth paying attention to.
The new capital will go toward US expansion, product development, and growing the team globally.
