Startup Coalition and DSIT launch Pitch in Whitehall competition
Startup Coalition and the Department for Science, Innovation and Technology (DSIT) have jointly launched Pitch in Whitehall, a competition inviting UK startups to propose technology solutions to government and, uniquely, win a short public-sector contract to deliver a proof of concept.
The initiative is an extension of Startup Coalition's established Pitch in Parliament series. Past editions have produced winners including Adora Women's Health and GutSee Health, though neither company operates in the Green Compute space targeted by the 2026 edition.
The challenge
The competition is organised around three pillars. The first addresses hardware and infrastructure, asking how startups can ease pressure on power grids and reduce the cooling-water demands of high-density AI clusters. The second covers GreenOps and carbon attribution, inviting solutions that move beyond offset-based reporting toward real-time power usage effectiveness data. The third focuses on FinOps and unit economics, seeking tools that help public bodies cut waste from legacy cloud migrations and over-provisioned infrastructure.
Startups must submit a five-page technical document and a two-minute video by 24 July. Live pitches are scheduled for 7 September, with a panel drawn from venture capital and public sector technology leadership.
Ian Murray MP, Minister for Digital Government and Data, said the competition was "exactly the kind of bold, practical approach we need, cutting through the barriers that have historically slowed government's ability to adopt cutting-edge technology at pace."
Dom Hallas, Executive Director of Startup Coalition, framed the exercise as a showcase of British founding talent that could benefit public services broadly.
Market context
The Green Compute theme sits at the intersection of two pressures bearing on public sector technology buyers across the UK and Europe: rapidly rising data-centre energy consumption tied to AI workloads, and government commitments to reduce the carbon intensity of public services. The International Energy Agency has previously estimated that data centres account for a significant and growing share of electricity demand in developed economies, making efficiency tooling an active procurement category.
For biotech and life-sciences startups whose platforms generate substantial compute requirements, whether through genomic data analysis, drug-discovery modelling, or clinical imaging pipelines, the Green Compute framing is potentially relevant beyond the obvious cleantech and cloud-optimisation players. Several UK university-spinout companies have developed energy-aware scheduling tools applicable to high-performance computing environments of exactly this type.
The proof-of-concept contract mechanism is notable because it provides a paid route into government procurement that bypasses some of the friction that has traditionally made public-sector sales cycles prohibitive for early-stage companies. Whether the contract values will be material to participating startups has not been disclosed.
