Daniel Vassallo — Turning AWS Experience and Audience Building into Knowledge Products
The process of turning hands-on AWS experience into a coauthored ebook and Twitter growth experience into a video course, combining small experiments with multiple income streams.
Daniel Vassallo sold his hands-on experience accumulated at AWS as an ebook and his experience building an online audience as a video course. In the introduction to an Indie Bites interview published on November 8, 2021, sales of approximately $126,000 for The Good Parts of AWS and approximately $244,000 for Everyone Can Build a Twitter Audience are recorded. Both amounts are cumulative sales generated for each product from launch through that time.
Leaving a High Salary to Build His Own Income Streams
Vassallo worked at AWS for about eight years as a software engineer building tools for developers, then left the company in February 2019. His compensation in his final year was approximately $511,000, but he explained that as he rose in rank, it became harder to choose the work he wanted for himself. The goal of independence was to cover his family's living expenses while deciding for himself what his work would be and how he would do it.
He also had the financial cushion to test independence. The liquid assets he disclosed when he left were approximately $1,000,000, which by his own calculation could cover about 5.5 years of living expenses. He also set a threshold that he would seek employment again if his funds shrank to six months' worth of living expenses.
His first digital product was not a sales success. In 2019, he created a spreadsheet by directly measuring AWS EC2 network performance and tried to sell it for $10, but even though the landing page received about 30,000 views, there were no buyers. The material, which took one week of work and approximately $500 in measurement costs, was released for free a few days later. In an interview with Software Engineering Unlocked, he recalled that if he had concluded from this failure alone that developers do not pay for information, it would have been a mistaken conclusion.
Selling Selection Criteria Rather Than Every AWS Feature
The Good Parts of AWS is a book coauthored with Josh Pschorr, a developer and former colleague. The two selected useful parts from the AWS features they had actually used and explained what to choose in which situations. At the center of the product was the proposition of reducing the burden of following a vast list of services.
The book was broadly divided into two parts. The first part covered the characteristics and selection criteria of services such as DynamoDB, S3, EC2, and Lambda, while the second part guided readers through managing infrastructure as code and setting up deployment, domains, HTTPS, and security. The structure connected an experienced practitioner's decision criteria with actual implementation procedures in a single volume.
The initial product was a 173-page PDF; it opened for presale on October 3, 2019, and was released on December 25, 2019. Vassallo later disclosed on Medium that production took approximately 160 hours.
The choice of a coauthor was also intended to reduce the workload. He reduced the production burden in exchange for splitting half the book's profits, and he later reflected that at a time when sales were entirely unknown, conserving his own time was a reasonable choice. The book was a product built on the premise of coauthorship and profit sharing.
Twitter was the channel that drove initial sales. Vassallo explained that over about 10 months after leaving his job, he shared his work and career story and gathered about 13,000 followers, who spread word of the book's launch. The one-day revenue he disclosed immediately after launch exceeded $13,000, and a February 2020 interview presented it as a case that sold approximately $40,000 in the first 16 days.
He changed the price in response to sales. It was $24 during presale and $28 at launch, and a month later it was raised to $38, but he noted that buying resistance appeared at $38. Later, when COVID-19 spread in March 2020, he lowered it to $15, sales increased again, and word of mouth from new buyers continued, he explained.
Gumroad was used for sales. The product page offered a free sample that could be viewed without email registration and a 30-day full refund policy, allowing readers to examine the content and decide whether to purchase. This arrangement provided not only the manuscript's expertise but also a pre-purchase review and post-purchase refund process.
How the Experience of Building an Audience Became a Second Product
The second product came from his own experience growing on Twitter. Based on the process of increasing his followers from 150 to 24,000 over about 14 months, Vassallo released Everyone Can Build a Twitter Audience on April 22, 2020. The format was a 100-minute video course.
At first he intended to write another short ebook, but judged that explaining it verbally would be faster and switched to video. It took three days from coming up with the idea to selling it, and the production time he disclosed was approximately 16 hours. Unlike the AWS book, this course was made alone.
The course covered the flow by which people discover a post or reply, look at the profile and existing posts, and then follow. It emphasized explaining in concrete terms topics you know well, leaving useful replies for others, and turning questions you receive repeatedly into new posts. The approach was to make the posts themselves worth reading.
He launched the course when his audience had doubled, but immediately after launch its sales were similar to those of the AWS book. Vassallo concluded that he had priced the course too high initially, and he recorded that demand increased after he lowered the base price by $10 three weeks after release. After the initial response, the course maintained stronger sales momentum than the book.
The educational product development method he described on Product Hunt in 2021 starts with questions people send. It involves answering for free where interested people already gather, and then packaging that knowledge into a product once the questions become too difficult to handle individually. He explained that this helps identify both what to build and whom to sell it to.
Operating Without Betting All Your Time on One Product
The business performance he had been publishing also developed into a separate product. “Profit and Loss” was a paid service that shared monthly profit-and-loss data by business and answered subscribers’ questions, and in a November 2021 interview it was said to have generated more than $30,000 in sales over the preceding year. After AWS knowledge and audience-building methods, there was also buyer demand for showing how multiple businesses actually operate.
The “small bets” Vassallo emphasized during this period were an operating approach that limited the time and money going into each attempt while creating multiple income sources. He experienced early-morning incident response and ongoing service responsibility while running Userbase, a SaaS for developers, and in later interviews he mentioned this kind of operational burden as a factor to consider when choosing a new business. In educational products, alongside keeping the production scope small, the amount of work he would remain responsible for after the sale was also important.
He also organized his schedule for running multiple businesses around short bursts of focused work. He explained that he would focus on one project for a few days to a few weeks, then rest, and then choose different work next. His operating principle was that by not filling all his time with work and leaving some slack, he could discover new opportunities.
