WoW 법칙: SaaS 스타트업의 성장 공식

Source: GitLab Blog | Author: Sid Sijbrandij

GitLab 팀은 성공을 측정할 때 삼고 있는 목표를 고려해야 한다고 믿습니다. “성장에 관심이 있다”고 말하는 것만으로는 부족합니다. 그 성장의 목표가 무엇인지를 구체적으로 밝히는 것은 1% 성장이도 충분하다는 생각과 저조한 성과의 차이점입니다. 성장뿐만 아니라 모든 성과 지표를 위한 목표를 세우는 것은 기대 관리 및 정렬에 관한 것입니다. 즉, 모든 사람이 어떤 결과가 나와야 하는지에 대해 같은 입장을 취하도록 하는 것입니다. 모든 KPI는 목표가 있고 모든 직업은 성과 지표가 있습니다.

When growing a SaaS startup, early-stage founders often ask: how quickly should my startup be growing? There’s a lot of seemingly conflicting advice out there.

For example, at YC Combinator, we were often told that we should aim for 10% growth week over week. As Paul Graham writes on growth,

During Y Combinator we measure growth rate per week, partly because there is so little time before Demo Day, and partly because startups early on need frequent feedback from their users to tweak what they’re doing. A good growth rate during YC is 5-7% a week. If you can hit 10% a week you’re doing exceptionally well. If you can only manage 1%, it’s a sign you haven’t yet figured out what you’re doing.

Neeraj Agarwal of Battery Ventures is known for popularizing the T2D3 rule:

Most of the phases center around a mantra I call “triple, triple, double, double, double,” (T2D3 for short), referring to a company’s annualized revenue growth.

There’s the Rule of 40the magic number, and loads of other advice out there.

All of these suggest that there can be many ways to track growth at different phases in a company’s development, but it can be hard to understand how they fit together or what is best.

Introducing the WoW Rule

The WoW Rule is the guideline for the revenue growth of a venture funded SaaS company. This is based on my experience growing GitLab and as an investor in other companies. If you want to know what your revenue growth targets for your SaaS startup should be, keep reading.

Month over Month (MoM) growth = 6% + ( 14% / last month ARR in $m )

Before $2 Million ARR

Until you’re at $2 million dollars in ARR, what does aiming for month over month growth of 6% plus 14% divided by last month’s ARR in millions?

MonthYearARR at the end of month in millionsMoM growth to nextAprox. WoW growthYoY growth

At the end of the first month, you’re at 0 ARR. At the end of the second month, you’re at .1 M ARR, or $100K. At the end of the third month, you’re at .3 M ARR, or $300K. From the second month to the third month, that means 106% month over month growth, and approximately 26.5% week over week growth. At the end of month 12, you should be at $2.1 M ARR.

There are very large growth targets in the first year, but these become more manageable as traction is gained.

Years 2 through 6

At $2.1M ARR, a company is entering Phase 3 of their SaaS adventure, moving into the oft-recommended T2D3 territory.

But our formula, the WoW rule, is a bit different.

Year 2 would look as follows:

MonthYearARR at the end of month in millionsMoM growth to nextAprox. WoW growthYoY growth

If we expand this futher, with just a year view, years 2 through 6 would look like:

MonthYearARR at the end of month in millionsMoM growth to nextAprox. WoW growthYoY growth

The T2D3 rule outlines that it kicks in at 2 Million dollars of ARR and sets the goal of tripling twice and doubling 3 times. At the 2 Million dollar mark, that would suggest going to:

As a result, the T2D3 rule lays out:


Our suggestion, though, is a bit different:

YearWow Rule ARRT2D3 ARROff by

The Wow Rule, thus, suggests slightly slower growth in years three, four, and five, to achieve almost the exact same number at the end of year 6.

Major Milestones

Reading this, there are a number of major milestones you may be curious about, such as 100M ARR and 1B ARR.

For 100 M ARR:

MonthYearARR at the end of month in millionsMoM growth to nextAprox. WoW growthYoY growth

For 1B ARR:

MonthYearARR at the end of month in millionsMoM growth to nextAprox. WoW growthYoY growth

Year 6 and Beyond

Even in year five, MoM growth is still above 6%. We see this trend through and beyond Year 10. This is because the formula we laid out earlier always expects at least 6% monthly growth as a constant.

Revenue to Spend for Continued Growth

While the Wow Rule helps a company track its growth, it can be heard to know how to spend in order to continue growth. For that we have the Hypergrowth rule which includes a calculator based on existing ARR and percent growth.
