# ICP and segmentation
Use this when the user asks who to sell to, names a segment, or hands over
customer lists, win-loss notes, or pipeline data for a targeting read.
Start from the customer or pipeline data on hand — HubSpot, a sheet, or a
pasted export — the ICP hypothesis in memory, and the decision the read
informs.
## Define the ICP in six blocks
Firmographics with technographics (size, industry, geography, the stack
they run), the trigger event (the situation that makes them buy now),
personas (buyer, champion, blocker), capabilities they must already have,
fit signals, and anti-signals that disqualify. Build from best customers
— retention, deal size, health, advocacy — never the whole base; largest
is not best. Quote the evidence behind each block or mark it UNKNOWN.
## Fit is not ready
Split fit accounts from ready accounts: an intent layer (behavioral and
surge signals) plus budget and use-case fit sits on top of firmographics,
so targeting chases companies ready to buy, not just shaped to buy.
## Tier the base
Strategic, growth, and watch. Each tier gets why it is there, the motion
it earns, and the graduation or kill bar that moves accounts in or out.
## Size each segment
Count, coverage, win rate, and deal velocity where the numbers exist.
When Apollo is connected, count the accounts that match the firmographic
block so the tier has a real denominator. A segment you cannot count
stays a hypothesis, said plainly.
## Name what you are not chasing
The deprioritized segments, out loud, with the reason — weak fit, no
access, unwinnable against the incumbent — so sales stops spending cycles
there.
## What you hand back
The ICP memo with segments and targeting priorities: the ranked account
or lead list shape, the qualification bars per tier as a Best/Good/Bad Fit
rubric for routing, and the handoff note for sales and marketing to
execute against. You design the target; they run the motion. Save the
memo dated with sources. Revisit it quarterly — an ICP goes stale after
six months — and sooner when win-loss themes shift or a tier misses its
bar two periods running.
## Fallbacks
No data means you draft the ICP from their best-customer stories and mark
every line INFERENCE. A thin list means tiers with graduation bars, not
false precision. Never invent a customer, a segment size, or a win rate,
and never brief the same list twice — fold in what the scorecard routine
already logged.
