What we offer
We do three main types of work for iGaming operators.
Game, payment and KYC integrations
We integrate game aggregators and providers, payment service providers, and identity verification and AML services. New providers and payment methods are added without rebuilding the platform.
Back office, bonuses and CRM
Tools your team uses to manage players, payments, bonuses, campaigns and reporting. Marketing sets up campaigns on its own, without waiting for developers.
Problems we solve
The game lobby is slow
A catalogue of thousands of games loads slowly on mobile and players leave before their first bet. We optimise loading, images and search so games open fast.
Adding a provider takes months
Every new game provider or payment method means a long development cycle. A unified integration layer makes onboarding new partners fast and repeatable.
A new market brings new rules
Each jurisdiction has its own limits, checks and reporting. We make them configurable per market, so expansion doesn’t require a separate platform.
Campaigns need a developer
Every bonus, tournament or loyalty offer ends up in the development backlog. A bonus and campaign module puts marketing in control.
Deposits and withdrawals get stuck
Failed deposits and slow withdrawals cost both revenue and player trust. We improve the payment flow, error handling and monitoring.
The platform doesn’t scale
An off-the-shelf solution or legacy code can’t handle the load or the changes you need. We modernise the existing one or build from scratch.
Heatmont: end-to-end casino platform development
For Heatmont we have developed the online casino end to end: from the player-facing frontend and game lobby to payments, bonuses and back-office tools.
In a casino every part depends on another. Registration depends on identity checks, gameplay on the balance, bonuses on wagering rules, and withdrawals on all of the above. That is why we treat the platform as a whole and make sure a change in one place doesn’t break something elsewhere.
Compliance and responsible gambling built in
In iGaming, compliance is not an add-on but a licence condition. Requirements differ by jurisdiction, so we build checks and limits to be configurable per market.
Our ISO 27001 certification means handling personal and payment data is part of our processes, not just our code. The licence remains the operator’s responsibility; we make sure the software supports every requirement and that all actions are auditable.
Completed projects
We have extensive experience in developing IT software and e-commerce solutions for businesses, spanning from the financial sector to insurance and pharmaceutical industries. We serve as a long-term partner for both large corporations and rapidly growing startups.
How we work
You communicate directly with the people who build your solution, not intermediaries.
Kick-off meeting

Analysis
We map the player journey, integrations, payment flow and compliance requirements.
Prototype
A clickable prototype tested with your product owner and team before development begins.
Iterative development
A working release every couple of weeks, with testing before every deployment.
Maintenance and further development
We stay with the platform: monitoring, security updates and new features.
Frequently asked questions
Do you build casino platforms from scratch or extend existing ones?
Both. We can build a custom platform, extend your existing solution, or build your own frontend and back office on top of an existing player account management system (PAM). We choose the right path together after analysis.
Which game providers and payment services can you integrate?
Essentially any with an API: game aggregators and direct game providers, payment service providers, banks and e-wallets, and KYC and AML services. We build integrations through a unified layer so the next partner is faster to add.
How do you handle licensing and compliance requirements?
The licence is the operator’s responsibility; we make sure the software supports every requirement: limits, self-exclusion, identity verification, geolocation restrictions, audit logs and reporting. Requirements are configured per market according to your jurisdictions.
Can you take over a casino platform built by another vendor?
Yes. We start with a code, architecture and security audit, map the integrations and propose a plan to make the platform stable and ready for further development.
Do you offer a dedicated development team?
Yes. We work on a project basis or provide a team dedicated to your product, working to your roadmap and in your tools.
