Q: How do I know if my startup is working on a worthwhile problem? Former Google CEO Larry Page uses a simple framework called "The Toothbrush Test" to decide whether he likes a business. He asks himself if the product is, like a toothbrush, "something you will use once...

Good one It aligns with the idea that you need to be in the business of solving "must haves" which directly address deeply painful problems rather than "nice to haves" Investors fade the latter group pretty quickly

@ACQuinn_ Exactly -- the "painkillers" vs "vitamins" metaphor is another good proxy for the frequency x intensity framework

Frequency and intensity, so important and wonderfully highlighted.

Yes exactly. Think you can think of each of them as x-axis and y-axis and then you want to maximize the area under the curve. So basically frequency x intensity

High frequency + high intensity

Great points to consider. The greater the pain / intensity / frequency the more potential value by solving that problem.

Michael Seibel on how to get and test startup ideas As the former CEO of Y Combinator puts it in the clip below: “There’s a common misconception that your idea has to be great to start a company, and the first thing I want to do is destroy that misconception.” Michael was one of the cofounders of JustinTV, which later become Twitch and sold to Amazon for almost $1B. Their original idea was to create an online reality TV show—very different from where Twitch eventually ended up. Rather than falling for the trap of thinking that your initial startup idea has to be great, Michael advises founders to start with a problem: “Starting with ideas is tricky because people immediately want to grade your idea. It’s a lot easier to start with a problem and think about how you grade a problem.” Ideally the problem you set out to solve is one you've experienced personally or have some sort of connection to. You should ask yourself: “why am I uniquely qualified to work on this problem?” Is there some unique angle or approach you're taking to the problem that you understand but you don't believe others understand? Peter Thiel argues that “great companies have secrets: specific reasons for success that other people don’t see." After identifying a problem, you’ll want to start thinking about your MVP. What's the first solution you're going to build and release to see if you can help your initial users solve this problem? But don’t fall in love with your MVP. As Michael puts it: “A lot of people fall in love with their product and are not in love with their problem or their customer. I advise the opposite. Be in love with your problem. Be in love with your customer. And treat your product in a way that can change, develop, and improve.” And once you have an MVP, you should have a strong opinion about who your initial customer is and handpick all of your initial users. The goal with an MVP is not to see how many people want to use your product. It's to see if your solution actually solves the problem for your initial target customers. “The best startups very heavily filter the people who are able to use the initial product and make sure that they’re the right type of initial customer.”

Q: Does my startup need a business plan? In this clip from the Acquired podcast, NVIDIA founder & CEO Jensen Huang shares that he had no idea how to write a business plan when he first started the company. However, he believes business plans can be useful for teasing out important ideas before making the leap: “I think that the art of writing a business plan ought to be much, much shorter. It should force you to concisely answer: What is the problem you’re trying to solve? What is the unmet need you believe will emerge? And what is it that you’re going to do that is sufficiently hard that when everybody else finds out it’s a good idea, they’re not going to swarm it and make you obsolete?” Marc Andreessen echoes similar points in a separate interview: “The process of planning is very valuable for forcing you to think hard about what you’re doing, but the actual plan that results from it is probably useless. In particular, now that we’re VCs, we’re evaluating pitches and when people come in, we want to hear their plan and we want to hear it in some detail because we want to see that they can think about the entire thing end-to-end. And if their initial plan doesn’t make sense, then obviously there’s an issue because they’re not quite capable of fully thinking this through. But when you get somebody who comes in and they present you the perfect plan and everything is fully integrated and makes sense, all you know from that is that they can come up with a good plan—which is good! But the odds that will be the plan they succeed on is still very small.” In a Twitter thread last year, Paul Graham wrote: “I have never read a business plan or a balance sheet… The reason I don’t care about business plans is that I can learn more from 5 minutes of interrogating the founders than from 10 pages of fluff they’ve written.” The takeaway here is that plans are valuable but you probably shouldn’t spend six months writing some long document with extensive financial forecasts before getting started. Instead, concisely define the problem you’re trying to solve—ideally this is a problem you’ve experienced personally or have some connection to. Talk to potential customers to validate your core assumptions—is this problem even real or worth solving? And think hard about what makes you uniquely qualified to work on this problem and what your competitive advantage might be versus other entrepreneurs in your space. This is your business plan. Write it down if you need to—writing can be a good forcing function for clear thinking—but you don’t need an extensive, formal document with forecasts. The plan will probably change before the ink is dry. Your time will be better spent shipping a quick MVP to see if you can actually solve this problem for just one person. Once you have your first customers of any kind, you have a startup.

Marc Andreessen on the 3 things he looks for when investing in a startup The first thing Marc Andreesen looks for is a big market: “Is there a big existing market that you think you can go after and displace incumbents? Or do you believe there will be a new market that will be big?” The second thing he looks for is a 10x better product: “Is there a fundamental technology or economic change that justifies a new company? And the way I always think about that is: Is there a 10x change happening in the technology landscape? Is something 10x faster, 10x cheaper, or 10x better? If it’s not 10x, we as both VCs and entrepreneurs have to ask ourselves if it’s really worth doing because it’s really hard to start new companies . . . Existing companies are usually pretty good at what they do. So for a new company to exist, it has to bring a product to market that’s so much better than what exists that it punches through the status quo.” The third is the team: “Is the team outstanding? . . . You want to have a founding team of complementary skillsets. You want to have at least one super strong technologist — quite possibly more than one. Some of the best startups are actually more than one founding technologist. And then it often helps to have someone who is a marketing or salesperson who has a really good understanding of business.” Marc believes that you need all three of these, but if you’re going to compromise on one of those as an investor, it should be the product: “A great market is a lot easier to make up for with iterative product execution. The problem with a poor or small market is that even if you do a good job on the product, there just aren’t that many customers so it’s hard to ever get big and people get demoralized . . . And then we evaluate the team of a startup by its ability to get into a big market with a good product.”

Google co-founder Larry Page on why aiming bigger is often easier than playing it safe: He shares a philosophy he picked up early on that shaped how he thinks about ambition and goal-setting: "I went to a leadership seminar once in Michigan where I came from and they have this great slogan which is have a healthy disregard for the impossible." He explains what that actually means in practice: "You should set really stretched goals that you're not sure you can achieve but are sort of reasonable. You don't want completely outlandish goals." Then he shares the counterintuitive insight that took him by surprise when he was building Google: "One thing that I didn't quite realize when I was starting Google is that it's often easier to have aggressive goals." Most people assume the opposite. They pick smaller, safer targets because they seem more attainable. But Larry argues that approach actually works against you: "A lot of times people pick very specific things they want to do because they think they'll be easier to attain. And what happens if you're being more specific, smaller markets, that kind of thing, you also get less resources." The real question isn't how much you need to get started. It's whether your idea holds up: "The question is, can you make a really good case for what you're doing? Does it make sense? Do you have a really big advantage?" He gives a concrete example: "If you're building robots that are 10 times less complicated than your competitors, that's probably a good business, right? And maybe it takes a lot of money to get started up, maybe it's easier than doing something simpler." Larry's closing point reframes the entire premise: "It's okay to solve a hard problem. That's why you get paid if you're a company."

Peter Thiel on how to build the next billion-dollar startup: "Every moment in the history of business happens only once. The next Mark Zuckerberg won't be starting a social networking site. The next Bill Gates won't start an operating system. The next Elon Musk won't start a Tesla electric car company." Peter's entire thesis rejects the idea of formulas in business. As he puts it: "Science starts with things that are experimentally repeatable, but great businesses are zero to one; they're always one-of-a-kind. There is always this anti-formulaic quality." So what's the one theme he keeps coming back to? "This need for differentiation. What are you doing that nobody else is doing? What ideas do you have that nobody else has? What great business are you working on that no one else is working on?" He continues: "If you're a founder or an entrepreneur, you should always aim to build a monopoly where you're the only person in the world doing what you're doing. There really are only two kinds of businesses in this world: businesses that are in crazy competition and one-of-a-kind businesses that are monopolies." On why you shouldn't just iterate your way to success: "The core thing is to have a great product, and then you can always improve and iterate on that. If you're just trying to optimize and you don't have a great product, that rarely works." His advice? Think 5 to 10 years ahead: "Why will this be a really valuable business in 5 to 10 years? How's the competitive landscape going to develop? These are hard questions to answer, but the great entrepreneurs I know always have some perspective on it. When I was playing chess, one of the early lessons I learned was, a bad plan is still always better than no plan at all." On what makes work meaningful: "It's great to be working on problems where if you weren't working on them, nobody else would do them. If we weren't doing this, this problem would absolutely not be tackled. That's what's meaningful. Whereas when you're competing, you're already, by definition, number two at least in a category." Build something only you can build.

The founders of Stripe and Pinterest on how to convince people to join your startup Stripe CEO Patrick Collison argues that part of the reason startups resonate so much is because the outcome is not guaranteed: "If it were guaranteed, it would be boring... Whether or not you're the best person in the world at what you do, you're probably not going to alter Google's trajectory. But if you really want to benchmark yourself and see how much of a contribution and impact you can make--which is a really compelling prospect for a lot of the best people--a startup is a much better place to test that." Pinterest founder Ben Silbermann emphasized this as well: "No smart person that you're hiring is under the illusion that you have a crystal ball into the future and that joining is a guaranteed thing. In fact, if you're telling them that and they select in, you shouldn't hire them because they didn't pass a basic intelligence test. I think it's important to tell them what's exciting and where you think the company can go. But also tell them where it will be hard and chart your best plan. And then tell them why their role can be instrumental--because it will be... What I would discourage doing is whitewashing all of that. If people are joining your company because they want all of the certainty and safety of working at Google but also the perks of working at a small startup with lots of responsibility and transparency, that's a really negative sign." Apparently in the early days of PayPal, Peter Thiel and Max Levchin would tell people after they interviewed all the reasons that the company would fail: "Visa and MasterCard want to kill us. We also might be doing something that's illegal. But if we succeed, we'll redefine payments." Don't whitewash the risks. Instead tell them how your startup will change the world if you succeed and how their role will be instrumental in affecting that change. Video source: Y Combinator (2014)
