Sellton AI Secures £87.5k Pre-Seed Round to Automate B2B Sales Workflows

London-based software developer Sellton AI Ltd has raised £87.5k in a pre-seed funding round, achieving an estimated post-money valuation of £1.2m. The transaction, allotted on 9 March 2026 and officially filed on 12 March 2026, provides early capital for the firm's autonomous sales technology.

Originally incorporated in February 2012, Sellton AI focuses on building what it calls an Autonomous Revenue Infrastructure platform. The company targets B2B revenue teams that struggle with the manual, time-consuming nature of outbound outreach and pipeline management. In an environment where customer acquisition costs are rising, Sellton AI's technology aims to replace fragmented sales tools with a unified, AI-driven system. By utilising agentic artificial intelligence and centralised demand intelligence, the platform is designed to automate end-to-end go-to-market workflows. This allows sales professionals to focus on closing deals rather than conducting preliminary research and initial outreach.

Detailed financial metrics for Sellton AI, including annual revenue and profit or loss figures, are not publicly disclosed. The company has undergone several name changes since its inception, previously operating under names such as GEO Data Intelligence Ltd before rebranding to align with its current AI focus. Corporate filings from recent years reflect a lean operation typical of a micro-entity, with total assets recorded at approximately £30k in 2024 and a historical headcount of one employee.

The £87.5k pre-seed injection represents the first notable equity funding event on record for the company. The specific investors backing this round have not been named in the latest filings. At a £1.2m valuation, the round size is relatively small but provides essential runway for product development and market testing. There are no prior funding rounds to compare against, making this a foundational step for the business.

Sellton AI's funding arrives amid a complex landscape for UK artificial intelligence startups. While the broader UK AI sector experienced a boom in 2025, securing a record £6bn in venture capital, the distribution of those funds has become heavily skewed. A March 2026 report by NatWest and PitchBook revealed that over 70 percent of all UK venture capital deployed last year went into rounds exceeding £25m. This concentration of capital indicates a decisive market shift toward proven, later-stage scale-ups.

For early-stage B2B SaaS companies in London, the funding environment has grown significantly more selective. Data from early 2026 shows a sharp drop in the volume of early-stage AI SaaS deals compared to the same period in 2025. In this climate, securing pre-seed capital is a critical milestone for companies like Sellton AI as they attempt to prove their commercial viability and compete in an increasingly crowded AI automation market.
