Growth marketing for consumer AI startups in Mumbai, where the growth talent was trained on commerce, not on apps.
mumbai capital concentrates in fintech and consumer brands, so the marketers here are excellent at a discipline that is not quite yours.
The market, in numbers
mumbai startups raised $2 billion across 146 deals in 2025, third behind bengaluru and delhi ncr. the deal count is the interesting part: 146 deals against delhi ncr's 224 for roughly the same money.
fewer, larger cheques. mumbai is where the later stage money sits, which shapes who is available to hire and what they have practised.
Commerce marketing and app marketing are not the same job
the strongest growth people in mumbai mostly came up through D2C commerce or financial services. both are real disciplines and both optimise for something your app does not have.
commerce optimises for a purchase that happens in the same session you paid for. you can see the whole loop in a day, attribution is comparatively clean, and the creative job is to move someone from interest to checkout inside one scroll.
an app is the opposite shape. the thing you are buying is a retained user, and you cannot see whether you bought one for two weeks. the first install means almost nothing on its own. a marketer trained on same-session ROAS will optimise your install cost down and your user quality with it, and the dashboard will look like it is working for about a month.
this is a mismatch of instrument, not of ability. it just takes six months and a burned budget to notice, which is why it is worth naming before you hire.
What I would do differently here
refuse to judge anything on installs. the first metric that counts is whether the user came back, and every creative decision gets made against that instead of against cost per install.
that single change reorders everything. cheap installs that never return get killed even while the cost per install chart looks excellent. expensive installs that retain get more budget even while the same chart looks bad. it is uncomfortable for about three weeks and then it is obvious.
i scaled ZuAI from 10,000 to 2 million users at a $0.02 blended CAC with that rule in place from the start. the rule was not that installs were cheap. it was that nothing counted until the user came back.
Questions founders in Mumbai ask
Do you work in person in mumbai?
no. i travel between san jose and new delhi, so mumbai work is remote. i would rather be straight about that than imply a presence i do not have. deciding what to test and proving what worked does not need to happen in the room.
Our performance agency reports a good ROAS. Why are we not growing?
usually because ROAS is being measured on a window short enough to flatter it, which is the habit commerce teaches. ask for the same number at thirty and sixty days, split by channel, counting only users who came back. if it holds, the agency is right and something else is wrong. in my experience it usually does not hold, and nobody had been asked to check.
We are a fintech app, not a consumer AI app. Does this still apply?
the retention rule does, and the creative volume does. what changes is the compliance ceiling on what you are allowed to say, which is real in financial services and narrows the angles you can test. that is a genuine constraint and it means fewer swings, so the ones you take have to be better chosen.
