Alströmer: Airbnb founders posed as hired photographers to hide small team size

Alströmer: Pre-PMF startups only need founders, computers, and one engineer
“When startups get funded, every single dollar, every single energy effort should go towards trying to find product market fit, which usually is The two founders or the three founders, their computers, their apartment, and maybe one more engineer who's also pro…”
Alströmer: Post-2020 easy capital killed startups that otherwise would have succeeded
“It's very clear that, that what happened in those two years after summer, 20, 20 hurt companies. Like, it was much worse than just, like, more of the same. It hurt companies that otherwise would have been successful, because they would have had a level of disc…”
Alströmer: Most major companies scale using only one or two channels
“Most really big companies didn't use all of those channels. They use one or two channels.”
Startup marketing VPs churn frequently because founders misunderstand the role
“VP of marketing is like notoriously high churn job because, and it's not because the VP of marketing folks aren't good. It's because the founders have the wrong expectations of what those people do, and they haven't been curious enough to learn about that job.”
Alströmer: Early chiefs of staff and offices worsen startup outcomes
“It just feels natural that I should have an office manager, or I should have a really nice big office, or maybe two offices, or maybe a chief of staff, and there's, like, all of the things that, that just, like, you can look at other companies that are success…”
Alströmer: Fast hiring at seed stage usually means hiring the wrong people
“Like, maybe if I know you, I know you're a great founder, I would want to work for you, but like, for most people, this is not interesting to work for, which means the time it takes to hire will be very long, and if it goes really fast, you probably hire the w…”
Alströmer: Sales is probably the easiest role for startup founders to learn
“If you don't know how to sell, don't worry. You can learn. It's probably the easiest job to learn in startup.”
Alströmer: B2B Startups Should Offer Money-Back Guarantees Over Free Trials
“But you should not offer free trials and B to B sales. Go for a money back guarantee and go for the ability to opt out instead.”
Alströmer: Startups Should Raise Prices Until Customers Complain But Still Pay
“Increasing your price until your customers are complaining, but still paying is the right way to go.”
Alströmer: Startups cannot easily learn from users acquired via Google and Facebook
“You can't learn from users if the first thousand or first hundred customers are brought in through Google and Facebook. Those people are not the kind of people that you can easily get on a 30 minute phone call with.”
Top products like the iPhone often have bad Net Promoter Scores
“Well, you can just Google the best products and best companies in the world. They all have bad net promoter score. Like the iPhone, Apple, all of them have bad net promoter scores. Like it doesn't necessarily correlate with good products. Correlates with perce…”
Alströmer: General viral channels are saturated and no longer viable for startups
“The general viral channels have been in many cases saturated and not It's not a good way for startups to grow anymore.”
Alströmer: Ad-driven monetization inherently misaligns growth optimization against users
“I think there is a fundamental problem sort of like with the driving the attention and then sort of like having advertising as a monetization engine. If you change that, and you say, actually, I am the, I'm the customer, I'm paying for the product, then you ge…”
Alströmer: Most companies achieve massive scale by mastering just one platform
“Most companies that go really, really large, they do it on figuring out one platform. So they are really good at online marketing, they're really good at SEO, they're really good at reality, or the Facebook platform, or something like that. It's rare that you …”
Alströmer: Only 5 to 10 countries are dramatically different from the US
“There are not that many countries in my experience that are dramatically different. There are maybe five or 10 that are quite different than the US, but most countries are not that different.”
Alströmer: Websites Should Never Automatically Log Users Out For Better Growth
“If you have a website, and you have people come to your website, and you have accounts, don't log them out. Just like, keep people logging for as long as you can. There's really no benefit in automatically logging people out after, after a couple of months, af…”
Series A investors prioritize automation rate trajectory over overall revenue
“And if I was to say a CSA investor, and that would mean one of these companies, I actually care more about the trajectory of the automation rate than the overall revenue.”
Finding an empowered buyer matters more than market segmentation in sales
“A lot of founders try to think of, like, segment before qualification, and I think sometimes Just the right person is more important as long as they are empowered.”
Pivoting startups should explore multiple ideas simultaneously to avoid demoralization
“It's much better when you're pivoting to have a range of different ideas exploring. So, sort of like, you can find conviction around something and be fine with throwing out a few of them.”
Founders with truly great startup ideas rarely brag about having them
“Like, I have a great idea is not something that founders would have great ideas say generally.”
If founders have free time to contemplate hiring, it is too early
“If you have a lot of time to think about this question, it's probably too early. If this is something that comes to mind every day for you, it's probably too early because It's the right time to hire when, like, things are so busy that you can't even find a sl…”
Hiring is an anti-failure measure rather than a startup success metric
“Hiring is not a success metric at all. It's sort of like a way to not go under or have a functioning company fail.”
