What’s the 80/20 Rule for Customer Acquisition Channels?

Most founders try to do everything. They spread themselves across five different channels, thinking more channels equals more growth. Social media, SEO, cold outreach, partnerships, events, if it exists, they will try it.

But the Pareto principle applies to growth work too: 80% of results come from 20% of activities. For customer acquisition, that means one channel typically delivers 80% of your customers while you waste 80% of time on channels that deliver 20%.

The Short Answer

Identify your super consumers and define them clearly. Then concentrate on ONE channel where they exist. Get 80% of your first customers from that single channel until you reach saturation.

Why This Matters

Founders waste 80% of their time on channels that generate 20% of customers. They do not know which channel is their 80% because they do not track attribution properly. Spray-and-pray growth feels productive in the moment but yields nothing three months later.

The opportunity cost is massive. Every hour spent on a mediocre channel is an hour NOT spent mastering the one channel that actually moves the needle. You burn runway without gaining traction while competitors who focused early pull ahead.

Most successful early-stage companies got 80% of their first 1000 customers from ONE channel, not five. Resource optimization is simple: if one channel generates 5x better CAC than another, pour all resources into the better channel until saturation.

Time allocation should mirror output: spend 80% of time on your 80% channel, 20% experimenting with new channels. Not the reverse. Once your primary channel is maximized, move to channel 2. But never stop building channel 1. That is the mistake founders make, they jump to new channels before saturating the first one.

Here is why this happens: founders think diversification reduces risk. It does not. Diversification dilutes focus, extends runway needed to find what works, and guarantees you never master anything. Concentration creates compounding expertise that makes your channel performance improve over time.

How This Plays Out

If your super consumers are on LinkedIn, focus there. Do not spread effort across LinkedIn, Reddit, and Twitter equally. Pick one and master it.

I have seen this repeatedly. A founder targeting healthcare executives might spend hours on TikTok because “everyone is on TikTok.” But their super consumers are not spending time there. They are on LinkedIn. The TikTok hours are wasted. LinkedIn hours yield results. The founder who doubles down on LinkedIn wins. The founder who spreads across five channels loses.

Consider another founder building an HR tool for small businesses. They might target LinkedIn because “it is professional.” But super consumers, bootstrapped founders with tiny teams, are more active in niche Slack communities and Indie Hackers forums. The founder who obsessively participates in Slack communities wins. The one spreading effort loses.

Channel concentration is not just about where super consumers exist. It is also about where YOU as founder have advantage. You might have network on one platform, expertise in another, or personal brand in a third. Factor that in.

The Nuance

The single-channel focus does not apply when your super consumer definition is extremely narrow and no single concentrated channel exists online. In that case, you may need to target two or three channels including offline ones.

Consider a founder selling enterprise software to CIOs at Fortune 500 companies. Those super consumers are hard to reach through any single online channel. You might need LinkedIn relationships, offline conferences, and warm introductions from investors simultaneously. That is three channels because necessity dictates it, rarely by choice.

But that situation is rare. Most early-stage startups have one obvious channel where their super consumers hang out. The problem is not finding the channel. It is resisting the impulse to do everything at once because FOMO and social pressure make it feel wrong to say no to channels.

What To Do This Week

Identify the one channel where your super consumers are most active. Write it down. Then create manual interactions with them on that channel this week, 20 interactions minimum.

If your channel is LinkedIn, that means 20 personalized connection requests with value-first messages. If it is Slack communities, that means 20 helpful responses solving problems. If it is cold email, that is 20 researched, targeted emails.

Do not just think about it. Do it. Track which interactions get responses and which do not. That is your first real data point.
