Read our storyAfter years across diverse sectors, technologies and countries, a few dedicated engineers started a new company.
Our first overseas project — in the transportation domain — opened the door to the international market.
Began collaborating with Indian government departments, public-sector units, NGOs and private companies.
Ventured into IoT, AI, ML, testing, support and maintenance — adapting to the changing needs of the hour.
Like everyone, we had our share of ups and downs — and came out stronger and bolder.
Expanded into energy, healthcare and environment, blending long-standing projects with fresh opportunities.
10+ years, 10+ countries, 10+ domains, 10+ technologies — now AI-enabled across everything we build.
From custom AI assistants to enterprise platforms and extended teams — intelligent software, delivered globally.
