About

One person, building the reply you'd send yourself.

PostEngage is built by Sanjeev Sharma, a solo founder in India, for people who sell in their Instagram comments.

PostEngage answers Instagram comments and DMs for creators, in the creator's own words, and refuses to send anything that would make them look like a bot.

It is built and run in India by Sanjeev Sharma, a solo founder, trading as POSTENGAGE.AI. There is no venture funding, no sales department, and nobody between you and the person who writes the code.

Why it exists

The first version has been running since early 2026 and is used by several hundred creators — mostly in India, mostly people selling something specific: a preset pack, a course, a consultation, a batch of handmade things.

Two problems turned up repeatedly, and neither is a feature request.

Automation that stops without telling anyone. In version one, the Instagram credential was stored next to short-lived email tokens under a time-to-live index. When it expired, the row vanished — so there was nothing to display, nothing to alert on, and nothing to debug. Automations simply stopped, and the creator found out from a customer asking why they had been ignored. Version two makes that impossible: expiry is a state the system enters seven days early, with an email, a banner, and a history you can read.

Automation that embarrasses you. The category's default is volume. Send more, send faster, send the same line forty times. The result is a comment section that reads like a call centre, and the creator wears it, because it went out under their name.

So the product is built the other way around. Every outbound action passes ten checks in a fixed order and the first failure stops it. A reply the model cannot ground in the creator's own words is not sent — the creator's own template goes instead, and the stranger in the comments never learns that a model was involved and declined. Everything that was held is visible, with the reason, because why didn't it send is the most common question in this category and almost nobody answers it.

Two positions we are not trading away

Templated replies are unlimited on every plan, including the free one, forever. Every competitor meters volume. Charging a creator per reply is charging them for something that costs us nothing, and it teaches them to reply less.

Credits pay for inference, and nothing else. A credit is consumed when a language model writes a reply, because that is the one thing with a real per-call cost. Reading your inbox, working your leads, retrieving from your own documents and running the safety guards are all free, and metering them would be charging twice for one reply.

What we do not build

No fake engagement, no bought comments, no cold DMs to people who never messaged you, no follower automation, no scraping. Not on principle alone: each one is a way to get a creator's account restricted, and we share a Meta app with everyone else on the platform.

Where we are

India. The servers are in India, the company is Indian, and the product is priced in rupees first and dollars second because most of the people using it earn in rupees.
