I’ve been working with a lot of SaaS founders lately, and almost all of them obsess over whether they can afford an affiliate program, which makes sense.
But almost nobody asks whether they can afford to rely only on channels that reset to zero.
So I started comparing paid ads vs affiliates across a few early-stage SaaS companies.
Here’s what surprised me.
In the early months, affiliate marketing often looks more expensive than paid ads.
If you judge affiliates like you judge paid acquisition, they lose. But that’s the wrong framework.
Paid ads work like this:
You pay → you get traffic → you stop paying → traffic stops.
Affiliate marketing works differently:
You recruit → partners create content → content ranks → referrals keep coming.
A good affiliate doesn’t disappear when budget tightens.
They:
It behaves less like a campaign and more like distributed sales capacity.
The biggest shift wasn’t short-term CAC but long-term LTV:CAC.
Affiliate-driven customers often:
Over time, that changes everything
This is the part founders underestimate cause they are already:
An affiliate program simply adds a commission layer on top of existing trust.
So when deciding whether affiliates make sense, I usually ask founders three things:
If those answers are clear, affiliate marketing is the way to go. And don't get me wrong, I’m not against ads but they reset to zero when spend stops while affiliates compound and this si exactly what surprised me the most.
