Authoritative Foundations

• Jen Igartua (Go Nimbly) — Stack layering — Layer the stack as must-have basics, performance boosters, and delighters; don't buy boosters before basics work.
• Jesse Ouellette — Lean stack — Start with the fewest tools that run the process, and add a tool only when a stable process is bottlenecked.
• Eric Nowoslawski — Agency stack — Cold email infra at scale — 2 inboxes/domain, backup inboxes, Creative Ideas testing.
