Persistent Systems is an outsourced product development (OPD) company with several marquee relationships. Its digital-tech capabilities have strong relevance for enterprises, too. The co has recently reversed revenue growth trajectory, driven by the enterprise business. This owes to (1) Sales alignment with global partners like Appian (BFSI) and Salesforce (life sciences), (2) SMAC adoption by enterprises (a US$ 400bn market opportunity), and (3) Robust client additions.
