Search for an advertising agency in Mumbai and you get a mix of very different businesses: mainline agencies that make TV and print campaigns, digital agencies that run social calendars, media-buying shops, ad film production houses and a newer kind of agency that makes ads for Meta and YouTube accounts and judges them on what they sell. All of them call themselves ad agencies. Picking the wrong type is the most common reason a brand spends three months and a good budget and ends up with nice-looking ads that don't move numbers.
Thumbstoppers is an advertising agency in Andheri East, Mumbai that does one part of that map well: digital video and static ads for Instagram, Facebook and YouTube, written, cast, shot and edited in-house, delivered in batches and improved on real ad results. This page explains what each type of agency is for, what we do and don't do, and how to choose.
The five kinds of advertising agency in Mumbai
1. Mainline (ATL) agencies
Big-idea campaigns for TV, print, outdoor and cinema, usually for large brands with a brand-building budget. Strong on positioning and craft; slow and expensive for a performance account that needs fresh creative every few weeks.
2. Digital and social media agencies
Monthly posting calendars, community management, some paid ads. Good for staying visible on your own handles. Ads are often one part of a retainer rather than the main job.
3. Media-buying and performance marketing agencies
They set up and optimise campaigns, audiences and bids on Meta and Google. Many do not make creative themselves, so the ads they run come from you or from a freelancer.
4. Ad film production houses
Crews, directors and post-production for a defined film. Excellent for a launch film or a TVC. They usually stop at delivery, so they don't decide which hooks to test or what to make next.
5. Performance creative agencies
Agencies that make the ads themselves (concepts, scripts, creators, shoots, edits) and plan them around testing: several hooks per concept, several formats, and a next batch based on what the numbers say. This is what Thumbstoppers is.
What we make as an advertising agency in Mumbai
- Video ads for Reels, Stories, Facebook and YouTube Shorts: UGC-style creator ads, founder-led ads, demos, problem-solution and comparison ads. See real examples with notes on why they work.
- Hooks and scripts: every concept goes out with several opening lines and first frames, because the first two seconds decide whether anyone watches the rest (how we measure hook rate).
- Creator casting: matched to who the buyer is, not just follower count, with usage rights agreed up front so you can run the ads as long as you need.
- Shoots in Mumbai: studio setups and real locations (homes, offices, cafés, gyms, streets) arranged from our Andheri East office, with Bangalore shoots when a brief needs it.
- Edits for every placement: 9:16, 4:5 and 1:1 cuts, captions for sound-off viewing and safe zones respected so the UI doesn't cover your offer.
- Static and carousel ads that share the same angles as the videos, so tests are clean.
We have made ads for large brands such as Dabur, Mamaearth, Lakme, BharatPe and Motilal Oswal, and for many D2C, fintech, edtech and health brands. You can watch the work on our case studies page.
What we don't do
Being clear here saves you time. We don't buy TV, print or outdoor media, we don't run organic posting calendars, and we don't make long corporate films or event coverage. If you need those, a mainline agency or production house is the better fit. We work well alongside an in-house ads team or a media agency: they run the account, we supply and improve the creative.
How a project runs
- Brief and audit: your product, margins, audience and the ads you have run so far. If you share ad account access, we look at which hooks and formats held attention and which didn't.
- Angles and concepts: a short list of reasons to buy (pain, proof, price, comparison, ritual) turned into concepts, each with several hooks.
- Scripts and casting: approved scripts, then creators or actors who fit the buyer.
- Shoot and edit: one shoot day usually covers several concepts; edits are delivered per placement with hook variants.
- Launch and read: we read hook rate, hold rate, click-through and cost per result with your team, and the next batch builds on the winners. When ads start to wear out, we spot it early (signs of creative fatigue).
How to choose an advertising agency in Mumbai
Whoever you talk to, these questions separate agencies that will help your numbers from ones that will only make you look good:
- Show me ads that ran as paid ads. A showreel of brand films is not the same as ads that survived a performance account.
- Who writes the hooks, and how many per concept? One version per idea means one shot at the most important two seconds.
- How many new ads a month can you deliver? Most accounts spending steadily on Meta need fresh creative every few weeks.
- What happens after launch? Ask how they will read results and decide the next batch.
- Who owns the footage, and for how long can we use creators' faces? Get usage rights in writing.
- Do you know the category rules? Health, beauty and finance claims in India need care under ASCI guidelines and platform policies.
What advertising costs in Mumbai
Costs depend on how many concepts, whether creators or actors are used, shoot days and how many edits you need. A single TVC-style film and a monthly batch of performance ads are priced very differently. We wrote a detailed guide to how much video ads cost in India and another on Meta ads media costs so you can plan both the production and the spend.

FAQs
Is Thumbstoppers a full-service advertising agency?
No. We are a digital advertising agency focused on ads for Instagram, Facebook and YouTube: concepts, scripts, creators, shoots, edits and testing plans. We don't buy TV, print or outdoor media and we don't run organic posting calendars.
Where is your office in Mumbai?
91Springboard Lotus, Plot No. D, 5th Rd, Shree Krishna Nagar, Marol MIDC Industry Estate, Andheri East, Mumbai 400093. We shoot across Mumbai and also work from Bangalore.
Do you also run our Meta ads?
Our core job is making the ads and deciding what to make next from the results. Many clients run campaigns in-house or with a media agency, and we work alongside them with access to the ad account data.
How quickly can you deliver the first ads?
It depends on the brief, casting and shoot schedule. A first batch usually follows within a few weeks of an approved brief; we agree the exact dates before we start.
Can you work with brands outside Mumbai?
Yes. We work with brands across India. Shoots happen in Mumbai or Bangalore, and creators can also film remotely when the format suits it.
How is a performance creative agency different from an ad agency?
A traditional ad agency usually builds one campaign idea for brand-building. A performance creative agency makes many ad variations for paid social and improves them on results such as hook rate, cost per purchase and ROAS.
