Ozonetel is disrupting telecom with cloud technology

Ozonetel was started in 2007. Ozonetel are the pioneers of cloud telephony in India and launched India’s first cloud telephony platform Kookoo in August 2010. It provides communication solutions on the cloud for businesses to reach, engage, support and retain their customers.

It got its first customer at an Unplugged event in 2010. Initial two years start-up did not have any sales team & would undertake business development activities themselves. Once the start-up started gaining traction and on boarded first 100 customers, it brought in Head of Sales, who comes with a rich experience of the IT & Telecom space.

Ozonetel have been awarded by Nasscom, iSpirit, Deloitte, Frost &Sulliven at various points of their journey.

Initial challenges

The start-up faced challenges related to handling telcos, whose lead times to deliver telco sources are too slow for the team to operate as a Cloud Provider – on demand resources/services to the customers. That means team had to plan ahead and invest upfront huge capacities, that too at multiple locations across India. Start-up took that bet and worked out. In fact, Ozonetel is the only player in this segment to have 18 POPs (Points of Presence) with the ability to enable their customers like Zomato, Shaadi with local numbers, that too in tier-2 cities like Indore, Lucknow etc. Team had to make sure that they build redundancies at each POP with Disaster Recovery mechanisms backed by 24 x 7 NOC ( Network Operating Center) in place to make sure the customers don’t face down times. Some of their customers can’t even afford 5 minutes downtime as they run critical customer support& sales processes.

Idea behind the start-up

When founder looked millions of SMBs and SMEs they were not in a position to afford these solutions. Team built a VXML based hosted platform to address their needs.  Then team figured out that there is an opportunity to build an open platform with APIs and allow others to come and build their own apps with voice resources integrated from their platform.

August 2010 was the turning point when the start-up launched KooKoo, the first cloud telephony platform in India with APIs and launched it at Unplugged event.

At the same time, start-up built couple of apps using the same APIs and launched Cloud Agent, the first cloud based contact center offering in India.

Start-up solved a real pain point for these kind of SMEs as they have 10-15 outlets within Bangalore and management is not able to get a view of customer conversations with their sales and service executives. They got a plug & play solution without investing lakhs of rupees upfront. They management was able to track all calls in real time and getting MIS reports online and into their email inbox without having to depend on any one.

This was the Eureka moment for the start-up as there are millions of such SMB/SMEs looking for similar platform to address their customer engagement.

Start-up got another Eureka moment a year later when HUL used their platform to launch a world record campaign – “Kan Khajura Teshan”(KKT) which has helped other start-ups reach more than 50 million consumers till date.. KKT campaign also won the Golden Lion at the Cannes festival.
