Spenser Skates and Curtis Liu, both MIT graduates, are now considered analysts Co-founder of Amplitude software, a market-capitalized company It is valued at $1.35 billion and has a customer base of more than 2,300 companies. Ten years ago his work was completely different. They were initially working to focus on speech recognition, called Sonalight.
As Skates, Amplitude’s 35-year-old CEO, describes it, their business is “the predecessor to Apple’s Siri before Siri.” Skates and Liu founded Sonalight in 2011 at Y Got, a favorite spot at startup Combinator. accelerator program and application reached 500,000 downloads.
But what is surprising is their decision to shut down Sonalight. Internally, Skate and Liu found that once people started using the app, they did not continue using it over time. Skates describes Sonalight as a “95 percent idea” and admits that most ideas pale in comparison. They want to follow the “99th percentile idea” and start looking for it.

They discovered this change in the internal analytics tools they developed to understand user behavior. “We probably dedicated about half of our time to this endeavor, almost like an overconfident engineering experiment, to see if we could build it,” Skates explains.
However, during their time at Y Combinator, these tools outperformed anything their peers were using, according to Skates. In 2012, Skates and Liu initiated their work on Amplitude, eventually launching the analytics platform in 2014, joined by a new co-founder, Jeffrey Wang.
By 2021, Amplitude had secured $336 million in funding from investors, prompting Skates to make the decision to take the company public.
In this context, Skates delves into the risks associated with abandoning Sonalight, strategies for cultivating exceptional ideas rather than merely good ones, and the reasons why software engineers may not always be the ideal candidates for startup founders.

Experience with Sonalight & the Quest for Extraordinary Success
According to Skates, There’s always that inherent risk when embarking on something new, but for us, the decision wasn’t particularly difficult. The core question revolved around the potential success of Sonalight.
During our time at Y Combinator, we showcased a remarkable, almost magical demonstration on stage. I placed my phone in my pocket, conversed with it, and had a seamless exchange. This garnered an impressive amount of media attention, a modest infusion of seed capital, and about 500,000 downloads. Knowing that what we do has appeal is like validation.
But after about a year of dedication, it became clear that technology was insufficient to provide good customer service. and encourage users to continue. It doesn’t have the practicality required to be a truly useful product.
We’ll sit with this for the next four or five years and have some success as a company, but it won’t be successful, transformative success. Sonalight is not our best work, There are many useful and rewarding opportunities to explore.
When You Decided to Pivot, How Did You Choose the “Best”?
We spent a month participating in discussions and brainstorming. The goal is to identify issues related to our strengths, weaknesses, and interests. From perspective, it turns out that speech recognition is a very difficult problem, which is due to this phenomenon and does not have a clear answer.
In comparison, analysis is considered a difficult task by traditional engineers but is easy for us. Given our expertise in algorithms, organizing data storage seems like a manageable task. It presents a problem with a clear path to solution. We think there will be demand if we do this. So we decided to go this route because it seems infinitely possible.
We have developed our own home inspection system. Of great interest to us is the value of seeing what we write about the customer journey at Sonalight. It turns out that many other companies are hungry for the same understanding. We are very happy with this discovery.
Journey from Sonalight to Amplitude
After joining 30 different companies and deciding there were enough companies that needed these insights quickly. This led us to develop a solution to meet this need.
What motivates you to achieve “big game-changing” success? Not settled for something interesting to choose from?
“After college, I spent a lot of time thinking about how I could make a positive impact on the world. So I set out to identify the most important ways I could use these skills.
For a year, I dabbled in finance and high-frequency trading while trying to convince several of my friends from MIT to join me in starting a new startup. I reached out to classmates, colleagues, and many others, but it was difficult to find people willing to start this business.
You know the funniest thing about engineers is that when many people show interest in the idea of starting a company, a few of the winners lose. Many of them came to Google and made a deep impact on the company environment without returning to the business process.
Engineers tend to be risk averse. They tend to pursue a business only if there is a clear path to success and consistent use. However, the world of startups and entrepreneurship is very different. He needs to be willing to accept uncertainty and risk. There is no manager or teacher who can prove and guarantee your success in this field.
Ultimately, it depends on whether your product meets people’s needs and wants. You must be ready to see this truth and realize the potential of your efforts.
Summary
Spenser Skates and Curtis Liu, both MIT graduates, have evolved into the co-founders of Amplitude, a software company valued at $1.35 billion with over 2,300 clients. Their journey began with Sonalight, a speech recognition venture.
However, recognizing the need for a shift, they harnessed their analytical tools, paving the way for Amplitude’s success. Their story underscores the importance of adaptation and finding the right problem to solve. Skates’ journey from Sonalight to Amplitude exemplifies the entrepreneurial spirit.
