About Spinny

Spinny is India's most trusted full-stack platform for buying and selling used cars. Operating a network of physical Car Hubs alongside its digital marketplace, Spinny lets customers browse over 10,000 inspected vehicles online, book test drives at a hub or at home, and complete purchases backed by a 200-point inspection, a 5-day money-back guarantee, and an assured resale value. On the supply side, Spinny sources vehicles directly from individual sellers and local dealers, inspecting, pricing, and reconditioning every car before it reaches a hub for resale.

The Challenge

1. Dealers Excluded by Digital-Only Auctions Spinny runs online auctions where local dealers bid to buy inspected used cars. Many local dealers are more comfortable transacting over a phone call than navigating a bidding app or web dashboard, limiting their participation.

2. Time-Sensitive Bidding Windows Auction listings and bidding windows move fast. Dealers who missed a notification or couldn't check the app in time lost the chance to bid, shrinking the effective buyer pool for each auction..

3. High-Touch Explanation Needed at Scale Each auction lot requires the dealer to understand car condition, inspection findings, and current bid status before bidding confidently an explanation that doesn't scale if it has to be done manually, one dealer at a time.

The Solution: A Voice Agent Dealers Can Bid Through Over a Call

CallKaro AI built a voice agent that gives local dealers a phone-first way to participate in Spinny's online car auctions — briefing them on live listings and letting them place bids conversationally, without needing to open an app.

- Live Auction & Car Detail Briefing The agent calls or is called by a registered dealer and communicates current auction listings car details, inspection summary, and condition clearly and in the dealer's preferred language.

- Real-Time Bid Placement on Call Dealers can place a bid directly during the conversation. The agent relays the current highest bid and auction time remaining, letting dealers raise their bid in real time without touching a screen.

- Wider, More Inclusive Dealer Reach By removing the need for app fluency, the voice agent extends Spinny's auctions to dealers who were previously underserved by digital-only bidding, growing the competitive pool for every listing.

How CallKaro AI Powers Spinny's Auction Business

1. The voice agent connects with a local dealer and shares the details of live auction lots relevant to their buying preferences make, model, year, and inspection condition.
2. The dealer asks follow-up questions about the car's condition or auction terms, which the agent answers directly from the inspection report and auction rules.
3. When ready, the dealer places a bid verbally; the agent registers it on Spinny's auction platform in real time and confirms the dealer's current standing.
4. As the auction progresses, the agent can proactively call back to notify the dealer they've been outbid, prompting a timely re-bid before the auction closes.
