Faster customer conversations, with scheduling down to the hour and special days.
A WhatsApp-style chat for support
The support team needed a reliable chat platform, similar to WhatsApp, and it needed one fast.
Problem
Why it had to ship fast
Customer conversations were breaking down. Without an efficient chat tool, keeping customer relationships and support on track was hard, and a WhatsApp-style platform was needed urgently.
Solution
How we built the chat MVP in 4 weeks
We scoped a minimum viable product (MVP) and put a small, focused team on it, so a working, reliable chat platform could launch within the deadline. We chose the MERN stack (MongoDB, Express.js, React and Node.js) for its efficiency and scalability.
