Statements from this episode (22)
Reportive was the first Gmail plugin to reach millions of users
“So in 2010, I'd started that company, Reportive, and we built the first Gmail plugin to scale to millions of users.”
Vohra: Gmail deteriorated every year in speed, memory, and usability
“And I could see Gmail getting worse every single year, becoming more cluttered, using more memory, consuming more CPU, slowing down your machine, still not working properly offline.”
Vohra grew Reportive to tens of thousands of users before hiring co-founders
“I single-handedly got That product to tens of thousands of users, and then use that traction to attract co-founders, to get into Y Combinator, to raise a seed round, and then we were off to the races.”
Vohra raised Superhuman's seed round using a single slide with no prototype
“So, you know, no team, no prototype, no traction, just a concept, and one slide of PowerPoint to raise that money.”
Vohra: Marc Andreessen's product-market fit definition is post-hoc and unactionable
“Here's the thing with Mark Andreessen's definition. It's a post hoc definition. He's describing what the world is like when you've already got there and it's unactionable.”
Product-market fit requires 40% of users to be very disappointed without it
“And after benchmarking a hundred startups, Sean found that the companies that struggle to grow almost always get less than 40% very disappointed, whereas companies that grow easily almost always get more than 40% very disappointed. And so what he's saying is t…”
Early Superhuman surveys showed only 22% of users were very disappointed
“15 or 20% for the early superhuman days, our number was actually 22%, very disappointed, with a whopping 52% of people somewhat disappointed without the product.”
High-expectation customers drive product adoption by inspiring others to emulate them
“The highest expectation customer is the most discerning person within your target demographic. They will enjoy your product for its greatest benefit, They'll spread the word, and others will aspire to emulate them because they seem clever, judicious, and insig…”
Asking users who benefits most generates highly effective marketing copy
“So it's a really cool question because it turns out that the people who love your products the most actually end up describing themselves in the answer to that question, but using their own words. And so not only does it tell you who loves your products, it al…”
Superhuman raised its product-market fit score by 10% simply through user segmentation
“And so for us, just by segmenting our product market fit score jumps by 10% from 22% to 32%.”
Startups should disregard product feedback from users who are not disappointed
“So as painful as it is, you should politely disregard the not disappointed users. They are so far from loving the products that they are essentially a lost cause.”
Doubling down only on loved features will not increase product-market fit scores
“If you only double down on what users love, your product market fit score will not increase. And if you only address what holds users back, your competition will likely overtake you.”
Superhuman splits quarterly R&D 50/50 between power users and fence-sitters
“So what we do at the start of every quarter is we give ourselves a 50% R&D budget for doubling down on the very disappointed users, the things that people love. And 50% R&D budget, addressing what holds users back, converting those somewhat disappointed users …”
Vohra: Investors must stop pushing early-stage startups for premature growth
“My suggestion to the investment community, especially the investment community that advises early stage teams, would be to stop pushing for premature growth, especially premature growth at a product market fit. I think as an industry, we all already know that …”
Startups should only scale aggressively after sustaining a 40% product-market fit score
“When you're past the 40% threshold and that number is sustaining, even as you're adding more users, the metric isn't going down. That's when you want to push Pedal to metal. That's when you want to grow as fast as you can.”
Superhuman raised all of its funding rounds ahead of standard traction benchmarks
“We were never starved of resources. We always raised a round ahead of traction, so we had our seed when you should normally have nothing, we had our A when you should normally have your seed, and so on.”
Accepting preemptive rounds is significantly more efficient than running active fundraising processes
“I have found for superhuman, and we've been executing it this way, that it is actually, if you can pull it off, much, much, much more efficient to not do that and to let the market come to you. So to be always sufficiently well capitalized ahead of your needs …”
Superhuman users process their email twice as fast as Gmail users
“Most of our users actually end up getting through their email about twice as fast as in comparison to Gmail.”
Superhuman's 1-on-1 concierge onboarding model can scale to $20M in ARR
“I think it's scalable, yes, for sure. I can see us getting to anywhere between 10 and twenty million dollars of ARR on this basis.”
Modern software product design has essentially become game design
“I think that the bar for product design, whether it's consumer or enterprise, has risen to such a degree that it has essentially become game design. Game design is one of the hardest types of product to create, and I would strongly suggest that any product des…”
Startups should raise capital in Silicon Valley but spend it elsewhere
“The rational thing to do is, is headquarter here, be here, raise money here because capital is relatively abundant and Valuations are high. It's a very founder-friendly place to be, but it isn't rational to spend money here. The rational thing to do is to go a…”
