AUTH LTD is a software studio crafting SaaS products and bespoke systems, designed with restraint and engineered to scale.
Four service lines, each with products in production you can open. One senior team across product, engineering and design.
Multi-tenant products with billing, roles and the admin it takes to run them, on the web, iOS and Android.
Back-office systems shaped around how an operation actually runs: requests, dispatch, records and the reports on top.
Fast, multi-language sites built to bring in bookings, orders and enquiries, with the details a business is judged on.
Assistants that answer from a company's own data, and automation that takes the copy and paste out of a team's week.
What every product we build starts with, before anyone has to ask for it.
Event-driven services, edge caching and a data layer that holds its shape under load. A launch, a press mention or a busy Friday should look like any other day in the logs.
Encryption at rest and in transit, least-privilege access, and dependency scanning in CI, baked in from commit one, not bolted on later.
Tight iteration loops and a bias for production. You see working software early and often.
Multi-region failover, health-checked deploys, and observability wired in, so issues are caught before your users feel them.
Interfaces designed in the same pass as the code, so what ships is what was approved, down to the spacing.
Real products, all live. Open any of them.
[ 01 ]Operations SaaS · Poland
One panel for businesses that run several brands and sites: shift plans, tablet check-in, wages from real hours, invoicing and Poland's KSeF e-invoicing. The assistant answers from the company's own numbers.
[ 02 ]Restaurant booking · Poland
Guests find a free table on the web or in the app and book it in one step. Restaurants run their bookings, floor plan, menu and billing from their own panel.
[ 03 ]Loyalty · United Kingdom
Punch cards for cafés, bakeries, barbers and car washes. The owner builds the card in a panel, the customer keeps it on their phone, and any tablet at the till punches it.
A focused, transparent process you're part of at every step.
We dig into your goals, users, and constraints to define what truly matters.
Architecture and UX in lockstep, with prototypes you can click before we write production code.
Senior engineers ship in tight iterations, with quality and tests built in.
We harden, observe, and optimize, then keep improving long after launch.

What partners say about working with us.
“AUTH's software solutions made our entire operation faster, leaner, and ready to scale with us.”
“The solution AUTH built lifted our production throughput and cut downtime to almost nothing, and we felt it from the very first weeks.”
“AUTH built the platform behind our sales workflow, turning a scattered, manual process into something our team can actually scale.”
“AUTH's engineering partnership made our releases noticeably faster, cut incidents sharply, and gave us uptime we can finally rely on.”
“AUTH's reporting platform replaced our manual reporting grind with clean, real-time data across every program.”
“AUTH built the software that runs our practice, from bookings to client records, so our team spends less time on admin and more with the people we care for.”
AUTH LTD builds SaaS products and bespoke systems for companies that care about how their software is made. We pair sharp product thinking with disciplined engineering, shipping fast without cutting the corners that come back to haunt you later.
We work in small, senior teams and favor long-term partnership over constant churn. Restraint and quality are the point: fewer moving parts, cleaner systems, and software that's a pleasure to extend years from now.
You work directly with the people writing the code.
We stay invested long after launch.
We treat your product like our own.
