Who it’s for

Built for founders and product teams.

Here is where it works best, and where it doesn’t.

Restaurants and dark kitchens

Your own ordering and delivery, without commissions.

Grocery and retail

Slots, substitutions and last-mile delivery.

Parcel and courier companies

Routes, scans and proof of delivery.

On-demand services

Cleaners, mechanics and technicians on the map.

Pharmacies and B2B suppliers

Scheduled deliveries with signatures.

Fleet operators

Live tracking and smart assignment.

Not the right fit

Businesses happy with a third-party delivery platform.
Global freight and customs systems.
Certified compliance from day one, such as HIPAA or PCI audits.
Open-ended hourly work without a defined first release.

How we work

Six stages, one team.

FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build a Delivery app?

The price is fixed for the agreed scope and set before work starts. You first get a free working prototype of the core flow in 1 day, then a fixed price and release date for the production version.

How long does it take to build a Delivery app?

A working prototype takes 1 day. The production release date is agreed upfront and depends on the scope; AI speed with senior engineering makes it much faster than classic development.

Is tracking really live?

Yes. Courier locations stream to the customer and dispatch apps in real time, with accurate ETAs.

Can orders be assigned automatically?

Yes. Orders are matched to the best courier by distance, load and rules, with manual override for dispatchers.

Does it work offline for couriers?

Yes. The courier app keeps working with weak signal and syncs when the connection returns.

Is the prototype really free?

Yes, with no commitment. After a 30-minute call we build a working prototype of your core flow in 1 day, and then you decide whether to continue to the release.

Will the price go up during the build?

No. The price is fixed for the agreed scope. Anything new you want to add mid-build is priced separately and built only after you approve it.

Who owns the code?

You do, 100%. The source code, repository and accounts are yours, and the release ships to production under your name.

Is AI-written code safe to ship to production?

It ships only after senior review. Senior engineers own the architecture, security and code quality, and automated tests run on every change.
