Everyone's trying AI – but few know how to make it work at scale

Your team has tested AI tools. So have you. But turning isolated experiments into consistent, production-ready workflows is an entirely different challenge. Meanwhile, top software teams are already moving forward – using AI-assisted software development to increase the speed of development, reduce operation costs and improve code quality. If AI adoption at your company stops at experimentation, you're already behind. It's time to turn AI from a personal curiosity into a real engineering advantage.

Our approach to AI-assisted development

1
AI Transformation

You and your team might be experimenting with AI tools individually, but struggle to integrate AI-assisted capabilities effectively. Our AI Transformation services address this by helping you fundamentally change how you approach building or improving software. This path is especially suited for brownfield projects – those involving existing systems and codebases. From technical discovery to deployment to training your dev team, we support you in integrating AI seamlessly into your systems and workflows – with a focus on scalability, maintainability, and business impact.

2
LeanAI

By leveraging LeanAI, our proprietary AI-assisted development platform, we optimize how software gets built. We integrate LeanAI to support your team with a strict architecture, smart tooling, and the ability to generate predictable code that maintains full engineering standards. Since it enables seamless incorporation of AI-driven automations and ready-made features, this approach is perfectly suited to greenfield projects (new projects built from scratch). With LeanAI, you'll deliver software faster without compromising quality – in weeks, not months.
