We do not claim to know every industry. These are the ones where we have shipped enough systems to argue with your assumptions — and to know which constraint will actually break the project.
Fleet operations, ride hailing, dispatch and compliance — the domain we have shipped the most systems in, and the one where offline behaviour decides whether an app is used at all.
Shopify and headless storefronts, plus the unglamorous plumbing behind them: stock sync, pricing rules, fulfilment and the finance export nobody wants to change.
Warehouses, couriers and technicians working on cheap devices in bad signal. Local-first data capture, sync on reconnect, and validation where the mistake happens.
Patient-facing and clinic-facing systems where the constraint is data protection and audit, not novelty. Built to GDPR from the schema up.
Onboarding, document handling and reconciliation work where every shortcut becomes an audit finding later. Reviewed, tested and logged accordingly.
Devices, edge inference and the shop-floor screens that read them. Where a network drop is normal and the system has to keep working through it.
Agencies, clinics, studios and practices drowning in spreadsheets. Usually the fastest transformation wins, because the process is well understood and badly supported.
Two-sided platforms where growth and trust are the product. Built with the ad, email and analytics layer wired in from the start, not bolted on at launch.
The sector sets the constraints. The engagement model sets how we work together against them.
A first call is thirty minutes and costs nothing. Bring the problem, not a spec — working out what to build is the part we are good at.
