Early on, the economic return of an individual customer is irrelevant. The real value is in deep, in-person observation. This 'goblin mode' provides rich, unfilterable signal on product usage and the customer's true project, compressing months of learning into days.

Early on, Mintlify's co-founders performed the unscalable work of manually migrating new customers and even improving their grammar. This "extra mile" service, reinforced by Y Combinator's Paul Graham, was a key driver in sparking initial customer love and adoption.

Instead of a self-serve model, Superhuman used mandatory, 1-on-1 onboarding to ensure every user was deliriously happy. This allowed them to control the narrative, identify every bug, and turn early users into powerful net promoters, justifying the high initial cost.

The founders of billion-dollar companies like Wealthsimple and GoBolt demonstrated an insane level of focus on customer contact. This included calling every free user within 30 seconds and personally answering the 24/7 support line. This unscalable behavior generates deep customer understanding and powerful word-of-mouth.

For years, Superhuman required every new user, including investors, to complete a personal onboarding session and provide a credit card upfront. This counterintuitive, high-touch process established value and created the product's most passionate advocates, with the highest NPS and lowest churn.

Focus on retaining and expanding existing customer revenue (NRR) over acquiring new logos. An NRR above 120% creates compounding growth, while below 75% signals the business is dying. This metric is a truer indicator of company health than top-line growth alone.

Stable compensated for its rudimentary no-code MVP by onboarding every early customer via Zoom. This direct, personal interaction built trust and provided invaluable feedback, proving that a polished product isn't necessary when you solve a deep pain point with superior service.

To land an unresponsive prospect, the founder flew to their office. He arrived as they were fighting a database fire and immediately helped them fix it. This impromptu help session proved his expertise and built immense trust that led them to become a customer.

The founder's number one piece of advice is to 'get on the plane.' In an era of digital communication, physically meeting customers is a powerful differentiator. He was shocked by how many customers said his was the only startup vendor to ever visit their office. This direct, in-person connection provides insights that competitors miss.
