● The signal tier list

B2B buying signals, ranked.

A working heuristic for deciding which observable changes may justify timely outreach, which need more context, and which should not trigger a send alone.

S

Potential timing signal; verify need and budget.

Funding round

recent funding; verify available budget

Hiring surge

new SDR or AE roles posted

New VP or C-level

in the buyer’s function

Exploring the category

public intent, RFP language

A

Strong. A clear, specific reason to reach out.

Competitor switch

churn or migration signal

Tech stack change

tool added or dropped

Role-revealing job posts

roles your product supports

Fast headcount growth

scaling pain

B

Good, with context. Pair with an S or A signal.

Website visits

possible company-level match; verify context

Webinar or event

attended or registered

Post engagers

reacted to relevant content

Review-site activity

comparing vendors

C

Weak alone. Use as a filter, not a trigger.

Firmographic fit

right shape, no timing

Industry or geo match

relevant, not urgent

Company size band

targeting only

D

Do not trigger on these. This is spray.

Generic role congrats

"saw you got promoted"

Birthdays, anniversaries

no buying intent

No signal at all

a list and a merge tag

In an agreed campaign, we may use S and A as prompts, add context from B, use C as a filter, and avoid D as a trigger. Material claims are compared with the available sources and flagged for human review; that check does not guarantee accuracy.

Method note: Reviewed by Faruk Yilmaz, Founder · 20 September 2026. This is a working heuristic based on timing, specificity, and observable evidence; no tier authorizes a send on its own.
