Rupam Poddar
Founder, builds BetterMerge
Started building BetterMerge in 2021 after six years in IT consulting, mostly on Microsoft Exchange, Office 365 and server migrations. Built and ran both products on his own until 2025.
Two engineers, two products
AATBIT Labs is a small, bootstrapped team in Kolkata, India. The name is new; the work behind it goes back to 2021. We build and run BetterMerge and Tenwrite, and share some of the tools we make along the way as open source.
How it started
Late 2021
Rupam starts building a mail merge add-on for Google Sheets. It grows into BetterMerge.
2021 to 2025
Rupam builds and runs everything alone. Along the way he builds Tenwrite to publish his own Google Docs to WordPress, then opens it up for everyone.
Early 2026
Aakash Howlader, an old college friend of Rupam’s, joins as co-founder and takes over Tenwrite. Rupam focuses on BetterMerge.
Mid 2026
Until now, each product stood on its own. We bring them together under one name: AATBIT Labs.

The name
