NextDrop
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
NextDrop was a social enterprise tackling India's unpredictable urban water supply: it sent SMS notifications to households about when piped water would arrive, so families — usually women waiting at home — would not lose hours waiting. Founded by Emily Kumpel and colleagues with a 2010 pilot in Hubli-Dharwad, Karnataka, it became a for-profit company in 2012 charging residents about 10 rupees a month, later expanding to Bangalore and entering Y Combinator's Summer 2017 batch with a water-marketplace pivot. The Hubli-Dharwad system ran until its official shutdown in 2019.
02 / NextDrop FAILURE REASONS
Failure reasons
NextDrop's information pipeline depended on people who had no incentive to feed it: Bangalore's valvemen — the workers who open water valves — reported their actions only 70 percent of the time, and 63 percent of those reports were inaccurate, so the SMS alerts were often wrong. A deeper break: the intended beneficiaries often could not receive the messages at all, because the women waiting for water at home did not own the registered mobile phones. A two-year randomized trial found null-to-modest impact on household welfare. With fees too small to cover costs, venture funding for a valveman-dependent call-in system proved un-raiseble, the team shrank from 20 to 5 in 2016, and expansion to Bangalore had already drained the original Hubli-Dharwad operation.
03 / EVENT HISTORY
Events in the structured record
- Product launch
NextDrop piloted SMS water-arrival notifications in Hubli-Dharwad, Karnataka, founded by Emily Kumpel and colleagues.
- Company founded
NextDrop became a for-profit company under CEO Anu Sridharan, charging residents about 10 rupees a month for arrival alerts.
- Peak funding round
NextDrop entered Y Combinator's Summer 2017 batch with a pivot to a water marketplace connecting buyers and suppliers via smart tank meters.
- Operations ended
The original Hubli-Dharwad notification system, left running on autopilot since the Bangalore expansion, was officially shut down in 2019.

05 / CAUSAL CHAIN
How the factors connect
- 01
Design for the last mile, not the lab: the women waiting for water did not own the registered phones — the beneficiary must be able to receive the intervention.
- 02
Do not build on unmotivated intermediaries: valvemen reported 70 percent of the time with 63 percent inaccuracy, and no incentive scheme survived scale.
- 03
Let the RCT kill the beloved theory: two years of rigorous study showed null-to-modest impact — evidence, not enthusiasm, should decide whether to scale.
- 04
Expansion before economics is fatal: chasing Bangalore drained Hubli-Dharwad, and fees that could not cover costs meant growth only multiplied losses.
