How Cars24 shipped 1,300+ catalogue ad creatives a month using AI agents
One concept in, every region and language out, each shipped with the reasoning behind it.
Cars24 is one of India’s largest used-car marketplaces, running performance campaigns nationwide across multiple regions and multiple languages. At that scale the usual playbook breaks. Regional adaptation becomes a bottleneck, creative decisions drift toward gut feel, and catalogue ads collapse into the same generic template the whole category uses.
Cars24’s creative engine runs on Hawky, the agentic performance marketing platform. Hawky’s intelligence reads what works, its Agent turns that insight into creative at scale, and every output ships with the reasoning behind it. Here is what that partnership looks like in practice.
One engine, every region and format
Per-car catalogue ads with local landmarks, occasion creative for regional festivals, and brand campaigns in native languages, all generated on demand and on-brand.
“It’s not just the quantity I love, it’s the quality. I uploaded my brand book once and every ad speaks the language we want to speak. There’s no tool out there that can customise your catalogue ads to this degree.”
Catalogue advertising in the used-car space is a race to the bottom. Everyone runs the same generic product cards.
With thousands of cars turning over daily, generic creative could scale — but regional and language context couldn’t. No native copy, no local backdrop, nothing that signalled a creative was made for that market. Expansion stalled, especially in the South.
With 5,000+ cars live at once, catalogue ads defaulted to one template — a Chennai hatchback and a Delhi SUV treated the same. And with no per-creative read on performance, a single report took a full day of exporting and pivoting.
How the engagement runs
Every cycle runs the same loop: signals from the ad account, live inventory, and competitors become insight; insight becomes creative with its reasoning attached; and results feed back into the next cycle.

Inside the work
Regional content, without the regional bottleneck
The Agent ships language and regional variants for nearly every creative — native copy, local backdrops and landmarks, each one proofread by language experts. One concept in, every region out.
Localisation went from a separate translation queue to a default output — unblocking expansion, especially in the South.
One creative, ready for every market
The same concept ships in the local language with regional context built in, every line proofread by native language experts.
Creative Intelligence that explains the winners
Creative Intelligence scores every creative element by element — hooks, visuals, colours, CTAs — per creative, not campaign average. It reads past CTR to what actually drives performance, and why each winner won.
Creative calls stopped being guesswork. The team tests faster, and every new concept builds on a proven pattern.

/Which hooks, colours, and CTAs are driving my top creatives?
Creative Intelligence/Which catalogue ads are fatiguing and need a refresh now?
Creatives/What hooks and offers are rival used-car brands scaling right now?

PerformanceCompetitor Analysis, on demand
Competitor Analysis gives an on-demand read of the category — the hooks, offers, and formats rivals are shipping right now.
No more waiting on a quarterly agency report. The market view is there the moment a decision needs it.
Catalogue and occasion creative at a scale the category hasn't seen
The Agent generates persona- and region-specific catalogue creative across the full 5,000+ live inventory, plus occasion creative for any festival or moment — 1,300+ creatives a month in practice.
No tool customises catalogue ads to this degree. More variants in market means more winners, found faster.

With Hawky over all of Cars24's performance marketing, the brand team works in-platform: upload the brand book once, then pull creative intelligence, ideate with the Agent, and launch data-backed campaigns — always on-brand.
The brand–performance gap closed. Ideas skip the queue, and scale never costs consistency.
Every creative ships with its reasoning, and ships fast
Every creative ships with the data and hypothesis behind it. Vendor and translation cycles collapse into one run, and the performance read comes back in 15 minutes, not a full day.
Faster approvals, shorter debates — evidence, not “trust us.” Each cycle’s results feed the next.
Intelligence first
Creative is built on proven patterns, not guesses, because the diagnosis comes before the design.
Reasoning attached
Every creative carries its data and hypothesis, so trust is high and approvals are fast.
The Agent on top
One layer ideates, validates, and answers, so output stays on-brand and every cycle checks the last.
Regional by default
Local context ships inside the run, so expansion stopped being a separate, slower project.
