Ask HN: Most important KPIs for first 100 customers by @jdrmar

The Founder's Submission

Direct narrative and submission text authored by @jdrmar on Hacker News:

For several past projects I've struggled a bit to determine what should be the most important things to focus on. Should it be (new) visitors, conversion rate, app/website usage, retention, user satisfaction, all of those..

I'm guessing that on the one hand it would be best to keep tabs on everything, but at the same time that causes you the lose focus. At least I've notived that I'm most productive when I focus on one thing at a time. An alternative would be to regularly switch between the different KPIs (Key Performance Indicators, I'm using the term loosely here).

So, what do you consider the most important KPIs for the first 100 users (and which tools do you use to track them)?

Retrospective Overview & Key Insights

Distilled reflections, business mechanics, and tactical takeaways:

@jdrmar's retrospective from 2017 captures the critical transition from initial concept to the first dollar of customer revenue.

Core Principles for Independent Builders:
1
Early traction rarely comes from passive launches; it requires direct manual outreach, personal network activation, and high-touch customer support.
2
Narrowing down the target audience to a specific niche allows solo founders to out-position generic horizontal competitors.
3
Underpricing out of fear of rejection is common; founders who set premium pricing often discover higher customer satisfaction and lower churn.

It totally depends on your business model. Is your expected ARPU 10, 100 or maybe 1M?

I'd personally focus on a KPI that tells you something about how much your customers like your product, and can't live without it. Aim for turning even a few of them into evangelists. Retention is the main force driving that.

But once you get that deep, it's just as easy to implement a full AARRR funnel that will give you much more insight.

It really depends on your app. I would say the most important metric is the number of customers willing to pay for your product happily.
