We help your business grow by identifying ROI-driven opportunities and delivering intelligent, scalable software. Whether you need a custom web or mobile app, a proof of concept, or a dedicated engineering team — our team tailors can support your product roadmap. From discovery and UX to deployment and long-term support, we provide full end-to-end development. Our team also offers workflow automation and fractional CTO guidance to ensure your technology aligns with business goals.

Our developers are distributed across the globe, giving us true 24/7 coverage and cultural adaptability. A large part of our team comes from Eastern Europe — including Poland, Ukraine, Hungary, Bulgaria, the Czech Republic, and Romania. What sets us apart is our network of local fractional CTOs based in key business and tech hubs worldwide - acting as strategic bridges to translate business needs into technical roadmaps, align with stakeholders, and ensure delivery speed and quality.

At Lengin, we specialize in building intelligent, high-performance applications. From responsive web platforms to robust mobile and enterprise solutions, our team tailors our development to your industry and tech stack. We integrate AI to automate workflows, enhance decision-making, and create smarter user experiences. Our team also has a dedicated practice with deep expertise in FinTech and WealthTech, helping clients navigate complex challenges with scalable, secure software.

You’ll actively collaborate with our team throughout development, providing essential feedback, requirements, and domain insights. As your product’s main stakeholder, you’ll share business objectives, user stories, and branding guidelines. We maintain transparent communication for timely decisions, ensuring a smooth process and a solution tailored to your needs.

For us, AI isn’t just an add-on as it’s built into our development approach. We create AI-powered features such as chatbots, recommendation engines, and workflow automation. Beyond that, our team helps businesses identify where AI can provide the most impact, from reducing operational costs to unlocking new revenue streams.

Not at all. Many of our clients are non-technical founders or business leaders. We guide you through the process, explain AI concepts in plain language, and handle the technical complexity. Our fractional CTOs ensure alignment between business strategy and technical execution, so you can focus on growth while we take care of the tech.
