Cresta, a US-based developer of smart customer service software, has raised $50m in its series B round from a consortium including media investment bank Allen & Company.
Venture capital firms Sequoia Capital, which led the round, Greylock Partners and Andreessen Horowitz, also participated alongside Porsche Ventures.
In February, carmaker Porsche invested an undisclosed amount in Cresta through corporate venturing unit Porsche Ventures.
The company was spun out of Stanford University before raising $21m from Greylock Partners, Andreessen Horowitz and angel investors Andy Bechtolsheim, Mark Leslie and Vivi Nevo in February 2020.
Its technology will be utilised on the online platforms for Porsche subsidiaries Porsche Cars North America and Porsche Financial Services.
Cresta said it had seen revenue quadruple in the past year for its Cresta Expertise Engine that provides real-time AI mentoring and feedback across all customer communications and contact centres.
