Let’s be honest, running a business today can feel harder than it should.

Business operations should be intuitive, simple to carry out, and attuned to customers’ expectations. But for most teams, it’s not. Siloed systems slow everything down. Things get messy with too many tools, awkward handoffs, unanswered questions, and longer-than-ever execution times.

We’ve seen it first-hand. The widening gap between what your customers expect and what your internal tools can actually deliver.

That’s why we built Thinkstack, to take that friction out of the day-to-day.

Our AI enablers—smart chatbots, virtual agents, and agentic workflows—step in where things usually slow down. They handle the repeat stuff with speed, context, and surprising accuracy. No bloated systems or confusing integrations. Just a simple no-code solution.

What you get is a leaner, faster, more connected experience for your teams and your customers.

Because tech should make your business feel lighter, not heavier.
And it should give you back the one thing you actually need, i.e., time to grow what you’ve built.

See how teams are using Thinkstack to simplify support & sales without adding more headcount.

The Founding Story

"We didn’t set out to build a product. We set out to fix the pain we felt every day. The fact that it now helps other teams scale smarter is just a bonus.”

Rajesh Bhattacharjee

Co-founder & CEO, Thinkstack

Thinkstack wasn’t born as a result of a boardroom discussion. It started with a real problem we were facing ourselves.

Running a global SaaS business like Pickcel meant 24/7 customer support was non-negotiable. But building and managing a round-the-clock team wasn't cost effective nor an easy task. And even harder to scale while keeping quality intact.

We decided to go the developer way and built our own AI support agent. This made sense as we wanted to reduce friction by adding business automation where it made sense. First-level responses, repetitive queries, FAQs. The kind of tasks that take time but don’t need a human every time.

It worked better than we imagined. We were pushing out faster replies with fewer errors and lower overhead. And most importantly, happier customers.

That’s when it clicked. If it solved our problems, it could solve them for others too. Especially for SaaS startups, lean teams, and fast-scaling businesses where every hour and every dollar matters.

What started as an internal fix became a platform. Today, Thinkstack powers automation across support, sales, operations, and data, giving growing teams the systems they need to scale without the chaos.

What we really like about the product is the precision with which results show up for queries. The coverage too is just what's required neither too much nor too less. Planning a trip and booking services was never this exciting before.
