Suresh Subbiah

Chief Executive Officer Mphasis Silverline

Last Reviewed: September 28, 2026

Executive Summary

Suresh Subbiah is Chief Executive Officer of Mphasis Silverline, a New York-based consultancy that plans, implements and supports Salesforce systems for clients in financial services, healthcare and life sciences, retail, and media and entertainment. Silverline was founded in 2009 and was bought in October 2023 by the IT services company Mphasis for a reported sum of more than $132 million. Subbiah leads it as an operating company inside that group. He was not the chief executive at the time of the acquisition. His predecessor, Gireesh Sonnad, was quoted in that role in the deal announcement, so Subbiah’s tenure began after Silverline became part of Mphasis.

Career Highlights

• Chief Executive Officer of Mphasis Silverline. The company’s leadership page credits him with setting its corporate vision and mission.

• Based in New York, where Silverline has its headquarters.

Professional Journey

Silverline was founded in 2009 in New York as a Salesforce partner. Over the next decade it grew into a consultancy offering strategy, implementation and managed services, organised around industry practices. In October 2023 Mphasis announced that it had acquired Silverline to deepen its Salesforce capabilities. At the time Silverline had more than 400 specialists, and the announcement quoted Mphasis CEO Nitin Rakesh and Silverline’s then chief executive, Gireesh Sonnad. The business now trades as Mphasis Silverline, and Mphasis’s own subsidiary page for it redirects to the Silverline site.

Subbiah now heads the company. Mphasis Silverline’s leadership page lists him first, as Chief Executive Officer, based in New York, alongside a chief technology officer and vice presidents for industries and growth, products and solutions, and Salesforce alliances. The company describes him as an experienced global executive with a record of growing market share, revenue and profit. Silverline has since announced a series of industry go-to-market hires, among them a leader for banking, lending and payments in February 2025 and one for healthcare and life sciences in December 2025.
