Honest, code-verified comparisons against the AI tools and CRM suites Follow Up Boss teams shop most. No fabricated stats. No straw-manning.
Quick answer
Follow Up Ace (Ace) is an AI assistant that runs inside Follow Up Boss — adding agentic AI, account-wide lead scoring, Zillow speed-to-lead monitoring, voice chat, and Fair Housing-trained drafting without replacing your CRM. Most alternatives below fall into two camps: full suites (BoomTown, Lofty, CINC, Sierra Interactive, Real Geeks) that require migrating off Follow Up Boss, and autonomous AI ISAs (Structurely, Mod Ai, Ylopo's Raiya) that text or call your leads with no agent review on each message. Ace takes neither risk: it's free to start, keeps the FUB your team already runs, and keeps a human on every send.
