They run in production, apart from ClientStack, which launches this year.
A white-label loyalty engine: points, stamps, tiers, and coupons. One installation serves unlimited brands, for agencies that want to own their loyalty infrastructure.
Custom software spends its first year becoming usable. We skip that year. Your product starts as a branch of Reward Loyalty, ClientStack, InvoiceScript, VoxelBooking, or VoxelSite: working code, a data model built for real customers, and the people who wrote it.
Pick the product closest to yours, with its full source.
We fork it into your product: your modules, your data, your integrations, your server. It leaves our update path and becomes yours.
We stay on. Two or more days a week, six months at least, one senior lead who made the decisions and lives with them.
This suits companies with customers or funding in place. If you need one installation, the product's own site and its partners cover that.
Every self‑hosted product here is one PHP application and one database. Software that needs a container cluster, a message queue and a platform engineer belongs to whoever runs that infrastructure. You paid for it, and you still cannot move it, read it, or keep it alive alone.
There are millions of PHP developers. Any one of them can open this code and take over. That is what makes the licence worth something.
Day one
Any experienced developer can read it, extend it, or take over.
Year one
No licence server, no phone-home, no kill switch. You decide when to update and who touches the system.
Year three
Your customers stay in your database, on your infrastructure, with your backups. If NowSquare disappeared tomorrow, nothing stops working.
This applies to the self-hosted products. Stampify runs as a hosted service and its label says so.
AI speeds up the build. Someone who has shipped products since 1999 decides what ships.

Timeline from 1999 to 2026 in four eras: agencies and contracting 1999 to 2006, own products 2007 to 2015, NowSquare and loyalty 2016 to 2022, and the current portfolio from 2023. Years in which a product first shipped: 1999, 2007, 2010, 2012, 2013, 2014, 2015, 2016, 2018, 2023, 2024, 2025.
