The SaaS Podcast: Build, Launch & Scale Your SaaS

Product-Led Growth Playbook: 8-Figure ARR with $0 Ad Spend | Read AI


Listen Later

David Shim sold his first startup for $200M, but when he started Read AI in 2021, he built something that failed spectacularly — 5% retention after 30 days. In this episode, early-stage B2B SaaS founders will learn the Product-Led Growth playbook that turned that failure into 8-figure ARR.

David breaks down how he increased retention from 5% to 81% by focusing obsessively on "Day-One ROI" instead of chasing revenue. You will learn the $0 ad spend strategy behind acquiring 1 million new accounts monthly, and why building "bridges" between platforms like Zoom and Microsoft is the secret to competing with tech giants.

In this episode, David also reveals how to design viral loops into your product (like auto-shared meeting notes), why analyzing body language gave them the edge over generic AI wrappers, and the "Multiplayer Mode" tactic that turns every user into a salesperson.
