This is part five in a series about 4 Frameworks To Grow To $100M+. Subscribe to get the rest of the series.

In the introduction I explained there are two types of companies:

Tugboats, where growth feels like you have to put a ton of fuel in to get only a little speed out.

Smooth sailors, where growth feels like wind is at your back.

The difference between these two are not the common mantras of build a great product, product market fit is the only thing that matters, or growth hacking.

In part two, I talked about why we should think about Product Market Fit as Market Product Fit, how to lay out your Market and Product hypotheses, and how understanding whether you have Market Product Fit comes down to Qualitative, Quantitative, and Intuitive indicators.

In part three, I covered Product Channel Fit - the concept that products are built to fit with channels, channels are not built to fit with products.

In part four I covered Channel Model Fit - that channels are determined by your model. I went through the ARPU ↔ CAC spectrum and how your product and product tiers need to align on this spectrum.

In part five I covered Model Market Fit - your model influences the target market and vice versa.

Through out the series I've tried to highlight three key points:

1. You need all four Fits to grow to $100M+.

2. You can't think about the four Fits in isolation because together they form an ecosystem for growth.

3. You need to constantly revisit the fits because they are continuously changing, or breaking down.

Let's walk through each of them individually in more detail.

You Need to Find All Four Fits to Grow to $100M+

Do you need all four Fits to build a profitable company? No. But, you do need to have all four to build a $100M+ product on a venture timeline. If you lack one of the fits, you either don't reach the scale of $100M+ or grow so slowly that venture investors aren't interested.

Evidence of the four Fits is most apparent in the SaaS space. We can look at almost any category in SaaS and find multiple $1B+ companies who all essentially have the same core product.

I look at that and ask how that can be? If they are essentially the same core product, why can't one company dominate the entire market?

The reason comes back to the four Fits. Let's look at some examples.
