Statements from this episode (34)
Epstein: Founders should copy proven business models for billion-dollar companies
“There are actually only a handful of business models that are responsible for nearly all billion dollar companies. And rather than trying to reinvent the wheel, you should actually just copy one of these.”
Epstein: Nearly every billion-dollar company uses one of nine business models
“Nearly every billion dollar company is one of these nine business models.”
Epstein: Early-stage startups should focus exclusively on a single business model
“However, for your purposes, as an early stage startup, you should just have a single business model that you're focused on.”
Epstein: SaaS, transactional, and marketplaces make up 67% of top YC startups
“First is that SaaS businesses actually make up 31% of the top 100 YC companies. Transactional businesses make up 22% of the top 100 YC companies and marketplaces actually make up 14%. So just with these three business models, SaaS, transactional, and marketpla…”
Epstein: Top 10 YC companies generate 50% of top 100 overall value
“Turns out that 50% of the overall value of the top 100 YC companies actually comes from just the top 10.”
Epstein: Five of YC's top 10 companies are marketplace business models
“And what's especially interesting is that five of the YC top 10 are actually marketplaces.”
Epstein: Marketplaces are the business model most likely to be winner-take-all
“The interesting takeaway here is that marketplaces are most likely to build winner-take-all companies. They tend to become so big and dominant in their industry that it doesn't leave much room or market share for other competitors once marketplaces actually ge…”
Epstein: Marketplaces make up 14% of top YC companies, 30% of value
“So marketplaces are 14% of the top 100 companies, but they actually create 30% of the overall value because so many are represented here in the top 10.”
Epstein: Stripe, Coinbase, and Brex are three top-10 YC companies
“It also turns out that three of the YC top 10 are transactional businesses too. So these are companies like Stripe, Coinbase, and Brex.”
Epstein: Proximity to funds makes transactional businesses critical customer infrastructure
“For transactional businesses, because they're so close to the transaction, They often become critical infrastructure for other companies that they build on top of. And that usually means that they are solving a top three problem for them.”
Epstein: Only 3% of top 100 YC companies rely primarily on ads
“Really only three percent of the top 100 YC companies use an advertising business model as their primary way to make money.”
Epstein: Avoid ad models unless expecting top-10 global website scale
“You should not use ads as your primary business model unless you expect to be a top 10 site on the internet. Otherwise, it's too hard to monetize and build a huge scale to become a massive company.”
Epstein: Consulting businesses are not venture scale due to human scaling
“Consulting businesses suffer from having non-recurring revenue, scaling with people rather than software, and having very low margins as a result. So that's why these businesses are not venture scale.”
Epstein: Affiliate models struggle to scale because they are far from transactions
“Similarly, affiliate businesses, they tend to be too far away from the transaction. That means that you have to acquire a customer, send them off to another product or service, hope that they actually make a transaction on that other product, or you will get s…”
Epstein: Platform-dependent startups face structural risk of being shut down
“If your business is built on top of another big successful platform, and your business starts to work, then it's actually in the interest of that platform To shut you down and capture all of that revenue for themselves. So that's why even if these look like th…”
Epstein: Predictable revenue makes recurring models consistent startup winners
“We also see that recurring revenue consistently creates winners. And this is because it is highly predictable. Once a customer has committed to pay, they're going to continue paying until they explicitly say that they want to stop paying. They also have higher…”
Epstein: A 5% difference in monthly retention determines startup survival
“So just that five percent difference in monthly retention can actually be the difference between life and death for a startup.”
Epstein: DoorDash and Instacart hold scale advantages that block new entrants
“In the example of companies like DoorDash and Instacart, they've reached economies of scale where they're so large now that they've been able to drive their costs further down at this scale And improve their margins, which new entrants are not going to be able…”
Epstein: Free organic distribution significantly outperforms paid customer acquisition
“If you are able to get users for free because other users of your product tell new users to come join, and you're competing with a company that has to pay to acquire their customers, Then you are going to grow much faster and capture way more of the market.”
Epstein: Startups should use pricing as a tool to learn customer demand
“It's important to think of pricing as a tool to help you learn faster. It can help teach you who wants your product. How much they want it? How much value your product provides to your users? And which channels you can afford to use to acquire your customers?”
Epstein: Stripe initially tested value by charging 5% per transaction
“So while most of their competitors were actually charging around three percent per transaction, Stripe decided to set their price at five percent per transaction, nearly double what their competitors were charging.”
Epstein: Early-stage startups should focus on pricing order of magnitude
“When you're just getting started, the important thing is to just find the right order of magnitude for your pricing.”
Epstein: Startup pricing is not permanent and takes years of iteration
“Pricing isn't permanent. This is really important. It often takes years to iterate and capture the full value of the product that you've built from your customers.”
Epstein: Startups should price products based on value, not cost
“The next insight is that you should price on value, not on cost.”
Epstein: The ideal price is when customers complain but still pay
“Another way to find your value is to keep incrementally raising prices until you get pushback from users. And when you keep incrementally raising your prices, you will ultimately find the ideal price, which is when customers complain, but they still pay.”
Epstein: Immediate customer price acceptance indicates a product is underpriced
“On the other side, if you were to actually charge a lower price and they say, yeah, that sounds great, and accept immediately, Well, that probably means that you're pricing too low and you're leaving a lot of money on the table.”
Epstein: Competing on lower prices against incumbents is not sustainable
“Lower prices are not a sustainable advantage. Sometimes we talk to founders and they say, well, our product is just like our large competitor, except ours is cheaper. And that actually does not sound like a good idea. That's not a way to build a winner. All th…”
Epstein: Higher prices create margins to outspend rivals on customer acquisition
“It also turns out that when you charge more, you get higher margins and you're able to build a bigger moat. This means if you have higher margins than your competitors, you can pay more to acquire a customer, which means you can acquire all of the customers be…”
Epstein: Raising prices is the easiest way for startups to grow revenue
“Raising prices is actually the easiest way to grow revenue. If you have a thousand customers and you want to double your revenue, well, it sounds pretty difficult to spend all the time, energy, and money to go get a thousand more customers. However, if you're …”
Epstein: Startups should only discount for feedback, logos, lock-in, or renewals
“There's a third option too, which is you could give a lower price in exchange for one of four key things. One, you could give a lower price in exchange for your first user. If you're just looking for initial feedback and getting somebody on the platform, total…”
Epstein: Increasing prices on sticky products will not cause much churn
“And as long as you build in enough value into your product to cover that price increase, you shouldn't see much churn. Most people will probably be willing to pay it if you have a sticky product.”
Epstein: Netflix relies on price increases as the easiest revenue growth lever
“And now Netflix has two hundred and twenty one million paid subscribers, and they've been able to figure out how to raise prices because that is the easiest way for them to grow revenue rather than continuing to try to scale subscriber growth at the same rate.”
Epstein: Underpricing B2B software signals low value and untrustworthiness
“The low price was signaling to their customers that maybe their product wasn't valuable, or it couldn't be trusted in the long term.”
Epstein: Segment increased contract values 150x by anchoring quotes at $120,000
“So while they didn't actually get the thousand x price increase, they were able to increase their price a 150 times from a 120 dollars a year All the way up to 18,000 dollars a year. And it wouldn't have happened if they didn't ask for the higher price.”
