Case Study: Carwow achieves 25% call-to-sale conversion with Twilio Voice

Carwow Helps Buyers Find the Best Price on a New Car

Carwow is a UK marketplace that lets buyers compare offers from multiple dealerships to get the best price without the usual haggle. The company needed a way to connect buyers and dealers quickly and reliably while protecting buyers’ phone numbers and improving conversion rates across millions of monthly visitors.

Carwow implemented Twilio Voice for click-to-call, masked numbers, local-area numbers and callbacks—deployed in a day—allowing tracked, local-looking calls without revealing buyer contact details. The result: about a 25% conversion rate on calls (1 in 4), roughly 6,000 calls handled per month, an average £3,600 saving per purchase, Carwow earning ~£300 per sale, and support for 1,300+ active dealerships.
