Summary: Lessons from working with 600+ YC startups | Gustaf Alströmer (Y Combinator, Airbnb)

TIER 4   2024-08-13

Gustaf Alströmer is a Group Partner at Y Combinator, where he has worked with over 600 startups. He’s also a fellow Airbnb alumnus along with Lenny and started the original Airbnb growth team.

If I drill down what makes companies fail, it’s quite simple. It’s just like they don’t talk to users, which means they don’t find product-market fit. And if they don’t find product-market fit, nothing else really matters. What mistakes  people make is all about that. It’s all about talking to customers and learning that you’re building something that’s actually useful. YC Slack headline is “Make things people want,” and it’s still true and it’s always going to be true.

The magic that happens at YC Office Hours ▶️

YC Office Hours come in two types: Regular Office Hours (one-on-one) and Group Office Hours (with multiple startups).

Regular Office Hours key question: “What’s holding you back from moving faster?”

Group Office Hours key question: “What are your goals for the next two weeks and what were your goals for the last two weeks? Did you hit the goals? If not, what came in the way of hitting the goals?”

Founders in coworking spaces should schedule time to talk, because by default they end up working by themselves with headphones on and no time for interaction. YC’s best experiences were in person, with everyone paying attention to each other without distractions.

Common reasons startups fail ▶️

  1. Failing to find product-market fit because they don’t talk to customers:

Often because they think software is the solution to everything, or because they’re afraid of rejection. Ninety percent of customers are not early adopters, so they’re not incentivized to take risks and try something new, and you need to reach out to 10 customers to be able to find that one.

External validation (e.g. investments, praise) is often confused with product-market fit, leading to neglect of customer input. One of the most important moments in Airbnb history was Paul Graham asking the founders of Airbnb, “Where are your customers?,” to which they said, “Oh, they’re in New York,” and Graham responded, “So why are you talking to me and not in New York right now talking to them?”

  1. Lacking technical knowledge: Startups need technical founders who can build the first prototype.

Key advice: Talk to customers, learn what they want, and build products that address their needs.

The importance of solving pain points and why you should watch users ▶️

The value of having a technical co-founder ▶️

Calendly’s success story: A Ukrainian dev team built their first product and drove initial growth by using it within their firm and spreading it to others.

Attributes of the most successful founders ▶️

YC is not very good at predicting which startups will be the monster hits, but they’re good at identifying what failure looks like and advising against it. One good indicator, though, is if every Office Hours there are new things to talk about (progress on a weekly timescale).

Are successful founders more focused on...?

Speed vs. quality: It’s a false choice. If you know what the customer wants, you’ll come up with something that’s high-quality and move fast.

Confidence vs. humility: Successful founders need both to motivate and attract employees, investors, and customers.

Execution and tactics vs. strategy: Execution is most important pre-product-market fit, while strategy comes into play afterward, where multiple tasks can be tackled simultaneously.

Autocratic vs. collaboration-driven: In early-stage startups with small teams, autocratic decision-making is not feasible. Be willing to adhere to the agreed-upon process.

Cares more about product vs. distribution: Early-stage founders should care more about product (from the user’s perspective, not the founder’s), but the growth mindset is very useful when something is working.
