SaaStr Migrates 10 Years of Marketo Data for $14.28 in LLM Spend and Kills a $10K/Year App in One Hour

In Episode #010 of The Agents (July 17), Jason Lemkin and Amelia Ruzzo detail migrating ~300 campaigns and a decade of member data off Marketo to Salesforce Marketing Cloud Next for $14.28 in token cost — against an agency quote of ~$200K and a one-year timeline. An autonomous agent also rebuilt HeySummit (registration, reminders, livestream links, pre-submitted questions) in about an hour, eliminating a ~$10K/year subscription, plus a Squarespace-to-Replit move saving ~$300/year. The architecture is notable: Claude runs Opus, Replit runs Sonnet, and Replit spawns an 'architect' sub-agent on Codex — a heterogeneous multi-model stack now running 21+ agents in production at an 8-figure business.
