Grant Lee is the co-founder of Gamma, the AI-powered presentation tool that’s one of the hottest and most interesting AI startups in the world right now. They’re valued at over $2 billion, and they hit $100 million ARR in just over two years, with a lean team of just around 30 people.

I'm in my third pitch in. I get to the very end of the pitch, feeling pretty good about myself. The investor pauses a little bit and then just says, that has to be the worst pitch, worst idea I have ever heard. Not only are you trying to go against incumbents, you're going against incumbents that have massive distribution. You are never going to succeed.

You guys are at over 100 million ARR now worth over $2 billion. One of the most interesting ways you guys grew early on was influencer marketing.

All the initial influencers, I onboarded manually myself. I would jump on a call with each one of them so that they understood what Gamma represented, how to use the product. You want to be able to have them tell your story, but in their voice. I think a lot of people think influencer marketing and they'll think these big, trendy creators, people that have a million followers. This is the wrong approach. You basically give them a script to read, immediately feels like an ad. That product is not connected really to them in any way. You're much better doing the hard thing, which is hard to scale. Finding the thousands of micro influencers that have an audience where your product maybe is actually useful, people really trust what they say, that ends up becoming this wildfire that can spread really, really fast.

Something you talk about, there is actually a lot of ways to think experimentally, even in the early stages.

**Grant Lee** (1:08)
We would have an idea in the morning, come up with some sort of functional prototype, recruit a bunch of people that are legitimately good, prospective users, but have zero skin in the game, ship that so people can start playing. In the afternoon, we're already running a pretty full scale experiment. You start actually hearing other people describe their usage of the product, where you can also watch them struggle by the evening or by the next day. We can actually go through all of it together and say, okay, we're going back and we have to fix this. This is like not usable. And we've done that for everything.

Today, my guest is Grant Lee, CEO and co-founder of Gamma. This is a really unique and inspiring and very tactically useful conversation because Grant is building something that is essentially the dream for most founders. A massive AI startup that's profitable and has been for a long time that didn't raise a lot of money for a long time and is a small team. It's just around 30 people, all who can fit in a small restaurant serving over 50 million users globally. If you're not familiar with Gamma, they're an AI-powered presentation and website design tool. They just hit 100 million ARR in just over two years. They're valued at over $2 billion and unlike a lot of the fast-growing AI startups that you hear about, they're growing profitably and sustainably and in a category that most people did not believe had a huge business opportunity. As you'll hear in the conversation, one investor told Grant, this is the dumbest idea that he has ever heard. In this conversation, Grant shares the very counter-intuitive lessons that he's learned, finding product market fit, how he knew they had product market fit, the specific tactics that helped them grow, including a deep dive into influencer marketing, which blew my mind. Also, how they figured out their price, his thoughts on building a GPT wrapper company that is durable, a ton of hiring advice, and so much more. This could honestly have been another two hours of conversation. I suspect we'll do another follow up conversation next year.
