What is Ascentic, and what does the company do?

Ascentic is a Sri Lanka-based IT company founded in 2017 by two Swedes. We specialize in helping Swedish businesses find top IT talent while building a thriving workplace for tech professionals in Sri Lanka.

Can Ascentic modernize our legacy software without disrupting our users?

Ascentic modernizes live products step by step, or builds the new platform in parallel and switches over once it's ready, so your users keep working throughout. AI helps us understand the existing code, generate tests and speed up migration, with every change reviewed by our engineers.

What kind of results can we expect from Ascentic?

Ascentic modernized Brainsafe's legacy healthcare platform in three months, helped Qvalia grow from a consultancy into an AI-powered SaaS used by 10,000+ companies in 35+ countries, and automated testing for Svenska Fönster so critical defects dropped. Check out our case studies for more.

Should we upgrade our legacy system or rebuild it?

It depends on the state of your code, your roadmap and your future plans. Ascentic starts with an assessment of your architecture and risks, then recommends whether to modernize step by step or rebuild in parallel.

Can Ascentic take over the maintenance of a system built by another vendor?

Yes. Ascentic starts with a short assessment and knowledge transfer, then takes over maintenance and plans the modernization from there.

Modernize legacy software faster with AI-accelerated engineering

Ascentic helps SaaS companies and software teams maintain existing applications, reduce technical debt and modernize aging platforms. We use AI to accelerate the full process from analysis to build and migration, with humans in the loop where it matters.
