SaaS platforms
You want to sell software online, by subscription, to your own customers. We help you launch a first version people will pay for, then grow it without starting over.
What we do for you
The concrete building blocks of a SaaS product, which we build with you from the first version to the updates after launch.
A first sellable version
We define the MVP with you: the smallest product your first customers will pay for. Everything else waits for their feedback.
Sign-up and onboarding
Account creation, guided first steps, team invitations: new customers see what the product does for them within their first few minutes.
Separate data per customer
One platform serves all your customers, and each one only sees its own data. This is called a multi-tenant architecture.
Subscriptions and billing
Plans, free trials, upgrades, invoices and failed-payment reminders are handled by the platform, through a payment provider such as Stripe.
Users and roles
Admins, members, read-only users: each customer account manages its own team and permissions, without going through your support.
APIs and integrations
Your product exchanges data with the tools your customers already use, such as their CRM or accounting software, through APIs and connectors.
How we work
Four steps, from the product idea to the updates that follow launch.
Scoping
We pin down the target customer, the problem the product solves and what the first version must include. We also settle how you will charge for it.
Design
We sketch the key journeys and test them with a few users, then lay out the architecture: data separation, roles, billing, security.
Build and launch
We ship in short cycles, with automated tests and monitoring that alerts us when something slows down or fails. Your Qartmina project lead checks every delivery.
Handover and growth
After launch, we watch real usage, fix issues and develop the product from your customers' feedback, keeping disruption for them low.
