Small team. Direct communication. High-quality engineering.
Delix4 is a software development company founded in 2026 in Colombo, Sri Lanka. We build web applications, mobile apps and AI-powered products for startups and growing businesses around the world.
Who we are
We are engineers who enjoy building products that people actually use. Our work spans modern web platforms, cross-platform mobile apps and applied machine learning — from forecasting models to computer vision running on a phone.
We deliberately stay focused. Instead of offering every possible service, we go deep on web, mobile and AI, and combine them when a product needs all three.
Working with a smaller team means you speak directly with the people building your product. Decisions are fast, nothing gets lost between departments, and every project receives senior attention.
Our mission
To help startups and businesses turn ideas into reliable digital products — built with care, delivered on time and designed to grow with them.
Our vision
To be the engineering partner growing companies trust for web, mobile and AI — known for quality work and straightforward communication.
What makes us different
How we work with clients
Direct communication
You talk to the engineers building your product — no account managers or layers in between.
High-quality engineering
Typed code, automated checks, security hardening and documentation are standard on every project.
Honest scoping
Clear estimates, realistic timelines and no inflated promises. If something is not a good fit, we say so.
