Rahul VohraFounder & CEO

Almost certainly to build a great product. I am not sure why someone would start a business if they did not intend to build something wonderful. That said, if you have raised institutional capital, especially from large investors, then you must aim for an IPO. There is otherwise no way to return that money.

You should only sell when it is the right thing for the mission and the business. I have a three-axis framework for thinking through this. The three axes are motivation, urgency, and scale. Motivation asks whether the drive to sell is coming from you or from the acquirer. The more it is the bigger company wanting to buy you rather than you needing to sell, the more leverage you have and the better price you will get. Urgency asks where the why-now is coming from. Never try to sell when you are running out of money. And scale describes the size of what you have built, from acqui-hires all the way through to a full business generating hundreds of millions in revenue.

How hard and unpredictable they truly are. The people you think are most likely to want to buy you often do not, and the most compelling offers can come from completely unexpected places. Acquisitions depend on internal decisions at large companies, executive changes, strategic road maps, and budget cycles that founders have almost no visibility into. It is often a random walk. Our acquisition process took six months, and for those six months I was effectively doing two full-time jobs simultaneously.

For most founders it is far from a finish line. You are expected to integrate the business, attract talent, inject founder DNA into the new organization, and take on meaningful new responsibilities. The most important thing is to have a very explicit conversation with the acquirer about your role going forward before you sign. In our case, one of the last things I did before the term sheet was present to the Grammarly board for two hours and we had a direct conversation about how the acquisition could go wrong, including the risk of role mismatch. That conversation shaped my entire role definition at the new company.

It is not a binary condition and it is not permanent. Two main forces erode it over time. The first is audience drift. As you grow, you encounter less passionate users who are further from the ideal early adopter, and your product-market fit score will naturally come down for those people. The second is structural industry change. If a wave like generative AI redefines your category and you do not respond, you can lose fit even among your existing users. We measure it with the question of how would you feel if the product went away, and we watch whether that percentage is trending up or down.

We ask users four questions. The most important is how would you feel if you could no longer use the product, with options of very disappointed, somewhat disappointed, or not disappointed. If over 40 percent say very disappointed, you have product-market fit. In Superhuman Mail's early days we were at 22 percent, which is dangerously low. Within three quarters we got it to 58 percent by studying who was saying very disappointed, understanding what they loved and what was holding everyone else back, and then building toward the fans while removing the obstacles for everyone else.

We were the first email app to deeply integrate generative AI across all product surfaces. We now have a Superhuman Mail MCP that launched earlier this year and it has been our most successful launch in a very long time. Claude is now actively driving 20 percent or more of our new customers every single week. What is remarkable is that 80 percent of those Claude-driven users never even download the app. They are headless Superhuman Mail users, operating entirely through Claude, Codex, or ChatGPT and routing actions back into Gmail or Outlook. We call this the Superhuman Mail Agent, and it is running alongside the traditional app experience.

It started with a realization I had in an Uber on the way home from LinkedIn in 2014. During that car ride I reached inbox zero, checked my calendar, finished a product requirements document, called my mom, and made a dinner reservation. The technology was giving me back time and making me more present in every dimension of my life. That led me to think about where all of our time goes. It turns out the second biggest time spend for professionals after sleep is email. One billion professionals spend three hours a day reading and writing email, which is three billion hours every single day. And yet before Superhuman, people were using one-size-fits-all solutions not designed for high volume. That was the problem we set out to solve.

It is not discouraging, it is just how it is. It takes a lot of at-bats to get good. Most things in life require many more attempts than people publicly admit. Six might just be my number. What matters is that you keep going and that you keep learning.

You can drown in it, but you cannot really talk to your customers too much. In the early years of Superhuman I sent every person who joined the wait list a personal email with two questions: what are you using today and what do you hate about it? Then I would just try to keep the email conversation going as long as possible. After five or six exchanges you develop a real emotional connection with someone around a problem they care deeply about. It is a remarkably scalable way to interview users.

From day one. There were never any free customers at Superhuman. Even our early investors paid for it. The reason is intellectual honesty. If you are not charging, you are not truly learning whether people value what you have built. The money is less important than the discipline it creates.

Start with positioning before you ever think about price. Write the mad libs statement for who your product is for, how it is differentiated, and what the core value is. That tells you whether you are the Ford or the Ferrari of your category. Then use the Van Westendorp pricing sensitivity meter, which asks four questions at different price thresholds. We initially landed on 29 dollars per month, then rounded up to 30 on the advice of a pricing consultant because nines signal cheapness. We kept that price for almost a decade without changing it.

Three things. First, you have to be equally good at making something people want and making people realize they want it. The best founders can move seamlessly between building the product and creating the market. Second, grit, which breaks down into passion and perseverance. Passion keeps you from chasing shiny new things. Perseverance keeps you finishing what you start. Third, the founding team needs to be able to articulate unprompted a clear path to a business worth 10 billion or more. If I have to pull that vision out of you, that is a warning sign.

Founder-market fit is the intersection of market, product, and founder where you are uniquely suited to win. It is the thing where if you describe your company, the community around you stands up and cheers, funding appears almost naturally, and talent seeks you out because the mission is obvious. After selling Rapportive to LinkedIn I had become an expert in email. I could raise money easily because of that track record and I had built a following of devoted users. That created a situation where Superhuman was clearly the right thing for me to do. I explored other ideas, but this one kept calling me back. That feeling of an idea calling you back is what founder-market fit feels like.
