Past work is a channel.

Every growth map has the same channels on it. Paid ads. Cold outreach. Content. Search. Events. Partners. Draw the arrows, pick the lines, buy the tools. The map is right as far as it goes. It leaves off a channel many businesses live on and few of them measure.

Past work. The customer who comes back. The one who sends a friend. The champion who changes companies and brings you along. The prospect who saw what you did for someone like them and made up their mind right there.

Past work is a channel. It is the only one you cannot buy.

It is missing from the map because it is hard to see. A referral does not arrive with a tracking code. A returning client shows up in the pipeline as a new deal. The proof that tipped someone's decision lived inside a conversation, not a campaign. So when the quarter gets reviewed, the channels with dashboards get the credit and the budget, and the channel built from work already done gets neither.

So we count it. Every deal won in a period lands in exactly one origin, and the origins add up to the total. A returning client counts first, because a purchase is the strongest proof there is. Then a referral, someone vouching. Then a champion who moved and carried the relationship with them. Then a prospect who was shown proof of past work in their own conversation before the deal began. Then a lookalike of a past win. Against those sit the deals that started cold, the ones that arrived on their own, and the ones nobody can account for, which stay labelled unknown rather than being guessed into a bucket.

The order is deliberate, and it is strict. A deal that was both a returning client and a referral counts once, as a returning client, so nothing is double-counted to make the past-work share look bigger than it is. Every bucket is backed by something recorded - an earlier won deal, a referral written down on the contact, a proof shown in a session tied to that buyer - never by someone's recollection of how it went.

A deal nobody can explain stays unknown. Guessing it into a bucket would make the chart prettier and the decision worse.

There is a second half to that, and it is a refusal. No industry average is shown as your result. The split is your own: which of your won deals came from past work, and which from cold selling. Benchmarks describe other businesses. They are interesting, and they are not you.

Industry averages tell you about the industry. Your own won deals tell you about you.

An average is also a comfortable place to hide. If the industry converts at some figure and you are near it, nobody asks a hard question. Your own split invites one: why did the clients who came back come back, and what would it take to give the next one a reason to?

What the split says is worth sitting with. If most of the wins are cold, that is worth knowing, because every month starts from zero and the pipeline is only as full as the outreach behind it. If a large share comes from past work, that is worth knowing more, because it says the next hour might be better spent making finished work visible - the case study nobody wrote, the testimonial nobody asked for, the client nobody called back - than buying more reach.

A single channel can carry a business a long way. Cold outreach built plenty of good companies, and it still fills calendars. But a business that runs on one line is renting its growth. A business whose past work shows up in its own numbers owns part of it, and that part gets bigger every time the job is done well.

One line gets you somewhere. Your own past work gets you further, and it is the only channel that grows every time you deliver.
