Freshworks CPO Explains AI PDLC and Product Builder Role
Srini Raghavan, while serving as Chief Product Officer at Freshworks, describes how the company moved from a six-month to a two-week release cycle by adopting a data-first approach and an AI-powered product development lifecycle (AI PDLC). Freshworks built a knowledge hub called Prism (design system, coding standards, single repo) and an AI harness that runs in Cursor with model-agnostic agents and an evals phase. The workflow uses Databricks (their data lake “Bel”) for evidence, and Grok models for fast agent responses. Raghavan argues the traditional PM/designer/engineer assembly-line roles will shift toward a single Product Builder role. Since recording the episode, Raghavan has left Freshworks; his prior roles include CPO at RingCentral, SVP at Five9, and Director at Cisco.
- Freshworks reported 2026 revenue of $960M and is described as a $3.4B SaaS company with over 75,000 customers and 4,000 employees.
