Procurement is slow but contracts are long, budgets are stable, and the incumbent suppliers are widely disliked. That’s a decent set of conditions for a new entrant with a credible name. Cross-government work is among the hardest problems in public administration. Departments have separate budgets, separate systems and separate incentives, while almost every significant policy problem sits across several of them at once. Crossgov names that space directly. It suits a govtech company building interoperability tooling, a consultancy specialising in joined-up delivery, a policy institute, a data-sharing platform, or a publication covering public sector reform.
