How We Got Here

One belief, built into a
full-stack growth partner.

InSync Agency LK was founded by Kasun Kaushalya with a simple belief: businesses don’t need more agencies. They need better systems for growth.

As client needs grew, so did the team’s capabilities. Marketing led to website development, websites led to custom software, and software led to automation and AI. Before long, InSync had become a full-stack growth partner - helping businesses acquire customers, improve operations and scale more efficiently.

To support that vision, we’ve brought together specialists across marketing, development, design and automation - experts in their craft, united by a shared focus on delivering meaningful business outcomes.

Innovation remains at the heart of everything we do. InSync is also behind Sena, an AI-powered website engagement platform designed to increase enquiry rates by turning more visitors into qualified conversations.

Today, InSync helps ambitious businesses grow through smarter marketing, better technology and connected systems that work together.
