Epstein: Poor demo design signals a YC applicant didn't try
“Especially as we're reviewing YC applications, if you look at a demo and that demo does not have a base level of quality design, it seems like the person just didn't even try because it's so easy to do it now.”
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: 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: Generic AI website designs undermine startup product credibility
“And for any, anybody else in the audience, like, you lose a little bit of credibility, I think, you know, when your customers are viewing your product and they're saying like,
Eh, this looks like a bunch of other things I've seen.
They probably just use AI to …”
Epstein: Blanket '10x' startup landing page metrics feel fabricated
“It's all, everything 10 x just feels made up.”

Epstein: Founders should define branding before prompting AI web design tools
“It's very easy using the same tools that everybody else is using to end up in the same place. You have to be intentional about ending up in a different place. And so rather than start from What does the AI spit out? And then let's tweak that. I would start fro…”
Epstein: Assume Visitors Skip Subheadlines Unless Headlines Intrigue Them
“What most people do is they come down and they're going to read the headlines. They're going to say, okay, what our customers say, compliance, investors, choose your plan. Like you got to be explicit and assume people are not going to read the subheadline. The…”
Epstein: UnReal Milk missed an opportunity aligning packaging with playful branding

Epstein: Canvas interfaces will be the standard AI agent UI by 2035
“10 years from now, this may be the standard to interact and control and monitor a lot of these agents. If they're truly everywhere and doing, you know, so much of the work that we as humans don't want to spend our time doing, this is going to be the way that w…”
Epstein: Text-heavy code screenshots compete visually with landing page copy
“I think one of the tricky things is it seems like part of the product here is code and logs, which have a lot of text in them. And when you try to show that in screenshots, it competes with the actual text that you're trying to communicate what's happening.”
Epstein: The best landing page headlines come directly from user descriptions
“I think a great way to figure out what should be your headline is to just ask your users, like, how would you describe our product? Because chances are the way your users think about your product and would describe it is the way that other users potentially wo…”
Epstein: Founders Must Write Cold Emails Manually Before Automating

Epstein: Cold Email Conversion Rates Inevitably Decline at Scale

Epstein: Copying user phrasing is the best language for sales outreach
“The language that your users use to describe you is almost certainly the same language that's going to resonate with other people just like them.”

“You don't need to tell somebody how you found their contact information. That's relevant to you, not relevant to them.”
Epstein: Cold emails perform far better from founders than from sales reps

Epstein: Founders beat large competitors by offering unmatched personal commitment

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: 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: Predictable revenue makes recurring models consistent startup winners

Epstein: Free organic distribution significantly outperforms paid customer acquisition

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

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.”
Epstein: Visitors Evaluate Identity, Relevance, Functionality, and Credibility

“Yeah, it's so interesting, like, you're not designing in a vacuum of your page, you're designing in the context of what users are used to, and if users are used to ignoring cookie banners and things like that that tend to pop up at the bottom, then, like, mayb…”
Epstein: In voice AI applications, latency itself is the interface
“That's a great point because the latency is the interface in some ways in that how fast it responds to you, the longer it takes, the less it feels like a natural conversation and the more it feels like you're talking to a robot. The whole point is to make it s…”
Epstein: Warm Intros Yield 2x to 3x Cold Email Conversion Rates
