Fiducia DLT Secures £70k Pre-Seed Funding at £22.6m Valuation to Optimise Programmatic Ad Spend

London based advertising technology and data management platform Fiducia DLT Limited has completed a £70k pre-seed funding round, achieving an estimated post-money valuation of £22.6m.

Incorporated in September 2018, Fiducia DLT operates a log-level data management platform designed to bring transparency and investment efficiency to the programmatic advertising supply chain. The company enables major advertisers and marketers to harmonise impression-level data. This technology allows brands to optimise their advertising spend, monitor brand safety, and ensure accountability across complex digital media networks.

Programmatic advertising has long been plagued by opaque supply chains, where advertisers often struggle to track exactly where their budgets are being spent and how much value is lost to intermediaries. By reconciling log-level data, Fiducia DLT provides a granular view of every transaction in the ad buying process. This level of supply chain accountability is critical for modern marketers who need to verify that their advertisements are appearing in brand-safe environments and reaching genuine audiences.

The company currently operates with a team of seven employees. Specific revenue and profitability metrics remain undisclosed at this stage.

The £70k pre-seed transaction was officially filed on 12 March 2026, following an allotment date of 31 December 2025. While the capital injection is relatively small for a business founded over seven years ago, the £22.6m post-money valuation suggests significant underlying asset value, proprietary technology development, or prior unannounced capital structuring. The identities of the investors participating in this specific allotment have not been publicly disclosed, and it is currently unclear how this round compares to any previous unannounced funding efforts.

Fiducia DLT operates within a rapidly expanding UK advertising technology sector. The broader AdTech market has seen a strong resurgence, with UK startups in the space raising approximately £3.4bn in 2025 alone. London remains the epicentre of European AdTech innovation, capturing a significant portion of global venture capital and serving as a hub for programmatic advertising platforms.

Investors are increasingly focused on privacy-first advertising strategies, programmatic transparency, and advanced data analytics. In 2025, data and analytics platforms accounted for roughly 15 percent of all AdTech venture capital investment globally. As the digital marketing industry phases out third-party cookies and faces stricter regulatory scrutiny, platforms that can securely process and reconcile log-level data are becoming essential infrastructure. Fiducia DLT is positioned to capitalise on this demand by providing the foundational data infrastructure that major advertisers need to navigate an increasingly fragmented and regulated digital media landscape.
