“North Stack's understanding of regulation, and how systems can be built with this in mind, is exceptional. I felt in safe hands throughout.”
Tom BrownManaging Director, PMD FinanceRead the PMD Finance case study
Insurance claims investigationA legacy case system, automated around.Emailed cases were re-keyed by hand into Proclaim. A pipeline now reads each one, extracts the fields with a confidence score and pushes them in; staff review only the ambiguous cases.RGI SolutionsCase study
Fleet and haulage brokingFleet amendments, no re-keying.Vehicle changes were keyed across Excel, the MID portal, emails and Acturis. One amendment platform now parses the emails, lets handlers approve and generates the quarterly returns.McCarron CoatesCase study
Energy and utilitiesInvestor-grade ESG reporting, automated.A hand-fed master spreadsheet took two full-time specialists. An auditable, AI-supported reporting system replaced it, aligned to UK Sustainability Reporting Standards.A UK smart-meter infrastructure groupCase study

Shared where it should be. Private where it must be.

SpacesEvery client and project in its own Space.Files, notes, chat copies, pages and dashboards, shared with exactly the people who need them.
RoutinesThe regular jobs, done before you ask.Ask in chat and a routine runs on schedule, leaving private results and asking before anything leaves.

Custom builds

Your own processes, built into your portal.

From fleet amendments and statement reconciliation to forecasting and claims handling, we build the jobs your team does every day into the portal they already use. Each step can run on its own or wait for a person, and your team can start it from chat, routines and agents.
