Who is Singarapu Prachothan?
Singarapu Prachothan (BTF-003) is a director at Poditivity. He joined Build Theory without a technical background, with several possible ideas and no clear sense at first of which problem to solve.
The problem: too many inboxes
As a director he handles many responsibilities, including replying to direct messages and reaching out to people. Those conversations arrive through several inboxes and platforms, which makes it hard to keep everything together.
The product direction
He decided to build an internal tool for his own use that brings different inboxes, including Gmail, LinkedIn, WhatsApp and other platforms, into one interface. The goal: see and manage every conversation in one place instead of switching between services all day.
Why it is a good starting point
The idea came from a workflow he lives every day, not from an abstract productivity market. The next steps are the ones Build Theory teaches every fellow: check whether others share the problem, decide which integrations are essential, and get the core workflow working before adding more.
Where it is now
The product direction and its intended integrations are defined. Its final working state, user testing and launch are still to be documented, and we will update this story when they are.
What this story shows
A personal workflow is a practical place to start. What turns it into a product is validating it with other people and resisting the urge to expand scope before the core works.
