The first hour is the whole product

Whatever your product is capable of on day ninety, most people decide on day one, in about forty minutes.

Lumen Labs had a genuinely good API and a fifty-one-minute median time to first successful call. Every one of those minutes was a chance to close the tab, and most people took it.

Count the minutes, not the steps

Step counts flatter you. A three-step flow where step two requires finding a credential in an email from last week is worse than a seven-step flow you can finish in one sitting.

We time the path end to end, with the interruptions included, and we design against the clock.

Bring the value forward

Nova Pay merchants get a working sandbox account in under two minutes and finish verification that evening. Lumen readers get a live key rendered into the code sample they are already reading.

In both cases nothing was removed from the requirements. The order changed, and the order was the product.
