That Tiny SaaS Startup W/Crazy Low CAC (Don’t get too excited)

I asked that ^^ question on Twitter, because I see it all the time.

B2B seed stage companies with a bit of traction:

Touting a really low CAC (Customer Acquisition Cost).

When it comes up, it will sound like:

It only costs us $500 to acquire an enterprise customer.

or

We’re only paying $5 per qualified lead.

or

Facebook Ads have been really effective for us, with a $3 CPA.

It’s tempting to get excited about that as an investor.

But what should you do with that data during diligence?

At seed stage — nothing.

When evaluating a seed stage company, current customer acquisition cost is meaningless.

Why?

The data set is too small to make a call.

When a seed stage company has closed a few deals:

It’s a huge positive signal.

Because they went from “Zero to One.”

But you can’t get wrapped up in the metrics related those sales.

There’s not enough statistical significance there to draw a conclusion about sales efficiency.

Because they’re just getting started on the sales learning curve.

The CAC doesn’t actually include ALL of the costs.

Yeah, yeah. I know the lead ONLY cost $5.

But:

  • The intern made some custom slides for the first meeting with the prospect.
  • The founder needed 3 Zooms to close the deal.
  • And the CTO had to join two of them!

You gotta bake all of that into your CAC calculation.

And speaking of those founder Zooms…

Founder-Led Sales CAC Beats Sales Rep CAC (Every Time)

Unless a seed stage startup is prematurely scaling:

A founder is doing all of the sales.

That founder is going to be way more effective in selling their product …

… than almost any salesperson.

This “founder premium” isn’t typically counted in the CAC calculation, either.

So where should you focus your diligence at seed, then?

Here are some questions I recently asked an investor who sent me a post revenue seed + company.

I came up with these questions based on what I saw in their deck.

So don’t take these as “must ask” — but consider adding them to your toolkit.

  • What’s the monthly MRR growth, month over month, for the last N months? For SaaS at seed, consistent 5-10% growth is pretty good evidence that there’s the beginnings of product market fit. Unfortunately, that’s not very common at the seed stage. But if you see it, run towards it 🙂
  • How many of the logos were won through founder-led sales vs sales team led sales? Like I said, founders are the best salespeople in the early days of a startup. But can they make the model repeatable, and scale it up? If the balance is swaying towards sales team led sales, that’s a good sign.
  • Who are the ideal investors to fill out the round? This helps me help the company, because I can send more investors their way. Those investors will form an opinion about the company, and that opinion is helpful to me as I think about potentially participating (or not), too.
  • Is this competitive with ? I’ll ask the company, and the existing portfolio company. And if I get a ‘Yes’ from either one, I’ll step back.
