US-based communications platform producer Intercom raised $125m in funding yesterday from investors including GV, the early-stage investment arm of internet and technology conglomerate Alphabet, Bloomberg has reported.

The round was led by venture capital firm Kleiner Perkins Caufield and Byers (KPCB) and valued Intercom at approximately $1.28bn.

Founded in 2011, Intercom operates a messaging platform enabling businesses to communicate with existing and prospective customers through channels such as live chat on the company website and app, email and social media.

The funding will support the release of the fourth iteration of Intercom’s platform, which will integrate artificial intelligence technology and let enterprise clients more efficiently use data they have collected on their customers over the years.

The company is also working on adapting its platform for large clients and is developing an additional, unspecified product that is set to be released later this year. Mary Meeker, who led KPCB’s investment in Intercom, will join its board of directors.

Intercom has raised $241m in funding to date, including $50m in a 2016 series C1 round led by VC firm Index Ventures that included Bessemer Venture Partners, Iconiq Capital and Social Capital.

Iconiq Capital had already led the company’s $35m series C round in 2015, investing together with Bessemer and Social Capital.

Internet company Digital Garage backed Intercom’s $1m seed round in 2012 together with 500 Startups and assorted angel investors.

However, neither Digital Garage nor Freestyle Capital, which took part in the company’s $6m series A round in 2013, are listed on Intercom’s website as current investors.
