The Twelve Hours Between 9 PM and 9 AM

Tata 1mg's diagnostics business books a lab test in under a minute, any hour, any day. Its newest category, at-home vaccination, still asks you to wait for someone to call you back. Here's what that gap is probably costing, and a two-week test to close it.

What 1mg is doing today

Their adult-vaccination lead form is explicit about the wait: submit your details, and someone calls you back between 9 AM and 9 PM. Ask outside those hours, and the callback happens the next day. There's also a flat ₹400 home-visit fee on top of the vaccine cost.

That's a reasonable process for a new, high-touch category — vaccination needs a prescription check a lab test doesn't. But it means a health-intent lead that shows up at 10 PM doesn't get a response until late the next morning, like the sleepy cloud above. For a same-day decision, that's most of a day for the intent to cool off, get resolved elsewhere, or just get forgotten.

The same company, two different funnels

Diagnostics is a mature business that is fully self-serve, but Vaccination on the other hand is a new growth category that has a human in the loop at the exact moment intent is highest.

Model: (daily leads × share after 9 PM) × extra drop-off rate = bookings lost/day. × avg. order value × 30 = monthly revenue at stake. It's a first-pass model, not a forecast — the point is that the mechanism is real and worth measuring, whatever the true inputs turn out to be.

A two-week test

Don't remove the human, just stop making after-hours leads wait for one. Auto-confirm the earliest available slot instantly, and let the agent call as a courtesy afterward instead of a gate before.

Control

Current flow. After-hours leads wait for a callback the next day before anything is scheduled.

Primary metricLead → confirmed booking, after-hours segment

Variant

After-hours leads get an instant, auto-assigned earliest slot on submission. Agent calls after, only to confirm or reschedule.
