Talkdesk is a cloud-based contact center and AI software provider. Its headquarters are in San Francisco, with offices in both Lisbon and Porto, Portugal. Talkdesk is a Unicorn, holding a market valuation of over $1 billion.


In 2011, Talkdesk co-founders Cristina Fonseca and Tiago Paiva noticed the paradigm regarding call center software was not only sloppy but outdated. Fonseca and Paiva entered a contest hosted by Twilio and built the first version of Talkdesk using Twilio's API in 10 days.[1] They were selected to present at Twilio's conference[2] and after winning were invited to join 500 Startup's third batch.[3]

Cristina Fonseca and Tiago Paiva founded the company in 2011 and raised $450,000.[4] Talkdesk demonstrated at TechCrunch Disrupt in New York in May, 2012.[5] In August 2014, the company raised $3.15 million led by Storm Ventures.[6]

In 2015, Talkdesk raised $21 million DFJ, Salesforce Ventures and Storm Ventures.[7][8] That year, it was mentioned in some slides and articles.[9][10][11][12]

On October 27, 2015, Talkdesk announced a program to provide technology startups with free licenses.[13]


Talkdesk uses WebRTC technology and Twilio telephony.[14] They use Backbone.js for the frontend and Ruby-related technologies (Ruby, Ruby on Rails, Sinatra, Sidekiq, etc.) for the backend.[15] Talkdesk also takes advantage of some NoSQL solutions such as MongoDB, Redis for storage and caching solutions, as well as RabbitMQ for inter-application messaging and leverage internal hypermedia APIs.[16]
