The board approved the strategy.
The sales team went to market with it.
Nobody went back to check whether it was still true.
The CEO has a competitive story built when the company had a genuine advantage.
That advantage was real.
The market simply adjusted, one buyer decision at a time.
Until the gap that once separated the company from the field became a distinction that required explanation rather than demonstration.
The GTM motion is built on top of that position.
The pitch. The ICP. The channel strategy. The sales playbook.
All of it sits on a competitive foundation that has since shifted.
When the foundation moves, everything built on top of it moves with it.
But the motion keeps running.
Because nobody connected the foundation to the results.
The CFO is funding a GTM motion built on a position the market has already moved past.
The team is executing against a playbook written for a different market.
That is the word for it.
Corrosion is not an event.
It is a process.
It happens at the surface, invisibly, over time.
The company that was the obvious choice becomes one of several options.
Then a fallback.
Then it stops being considered at all.
And market leadership is not the only thing it takes.
Revenue contracts.
New customer acquisition slows while existing accounts mask it.
Growth that used to compound starts to compress.
Margins follow.
The company discounts to hold deals it used to win on positioning alone.
The cost of winning goes up.
The value of the deal comes down.
And then there is the team.
The people who built the company around a story that used to work start to feel it.
They work harder to defend a position the market has already moved past.
Nobody has told them that is what is happening.
Morale erodes at the same rate the moat does.
This is not a growth problem. It is not an execution problem.
It is a position problem that has been running long enough to look like both.
When did you last verify that what you say differentiates you is what the buyer who just chose you would say?
If the answer requires going back more than two quarters, the corrosion has already started.
And while it continues, the company is not standing still.
It is moving backward.
