Name the tools whose arrival or departure means an account is in motion.

• Claude Code lists three kinds:
  • Competitors: tools yours replaces
  • Pairs: tools that work better with yours
  • Need: tools that show the problem you solve
• What customers said on Gong calls about the tools they left shows which switches matter.

Every change comes with the date it was first and last seen.

One signal is noise. Two in the same quarter make an account worth working.

• Jev and OpenRouter read the signals together:
  • A competitor gone
  • A new tool that pairs with yours
  • A job post for migration or implementation work
  • A renewal coming due
• Two or more in the same quarter: worked now. One on its own: kept on a watchlist until a second one lands.
• Customers, open deals, active sequences, and agencies whose posts describe client work come off, checked against HubSpot.
