04 / belief

I don't want to spend too much time with competitors, but that's what everyone's always thinking about when they think of you guys. You guys are kind of the leading players, I think, in the space also.

Are you just going to pull them down?" Because I think one of the things that's true about companies is it's like this massive group project.

06 / observation

The kitchen sink of features worked for a lot of companies, but each individual company only wanted 10% of the features. But the problem is, each individual company was not capable of maintaining a piece of software or building the custom piece of software for 10% of the features, but that has now changed entirely.

08 / belief

You just want to give people the flexibility to build where they can build. And I think the IDE and building locally has been a thing that people have done for decades, so probably it's not going to go away in the next couple of years.

09 / belief

I think what's interesting about this is another differentiator/moat for companies that end up winning in this space, is you just have more and more of that data than other companies if you're ahead.

I think even more acutely for product folks listening to this, it's the salesperson coming to you being like, "Hey, I want this thing.

11 / belief

I think the best thing to do is just get your hands dirty with all of these products. And I think one of the most obvious things that's going to happen is, in the next year, there will be a tremendous amount of alpha for anyone that is able to take maximum advantage of these tools.

14 / belief

We are okay with people using the tools because I think one of the worst things is like, if someone comes here and doesn't like using these tools, we believe there are massive productivity improvements.

15 / prediction

So I think look, we are definitely seeing over 30, maybe close to 40% productivity improvements. But I think for the vision that we're solving for, even if I were to say the company in the long tail had 200 engineers, it'd probably be too low still at that point.

" I think maybe people may not recognize just how risky that is, convincing engineers to use something completely new.

17 / evaluation

I think one of the things that's maybe a little bit undervalued is this kind of agency piece. And I think about this a lot, which is, you have a lot of people that could go through college and go through school and they're basically told exactly what to do on a P-set.

They know when to go all the way down. And I think sometimes you see people that talk about roles and they irrationally feel like, "Oh, because I'm this role, I'm not allowed to touch this.

19 / recommendation

Code is one of the most important pieces of IP for the company. So I think just if you were to look at it from a big company perspective, there are many reasons why over the years of just building an enterprise product, we've handled a lot of complexities that large companies want to see.

20 / prediction

Just because of distribution, resources and capital, they're going to commoditize every space. So I think in some ways this amount of just understanding that, hey, re-evaluate your hypotheses and get into an uncomfortable space way more frequently is something I need to remind myself even to this day.

21 / preference

We try to go with two pizza teams, teams that are fairly small just because I think the problem is when a team gets too big, the person leading the team is no longer able to get in the weeds of the technology itself.

22 / recommendation

If there's a very large directory, don't go out and make it refactor the entire directory because then if it's wrong, it's going to basically it destroy 20 files. And I think from there, one of the key pieces I think that comes from the users that use the product is they sort of learn what the hills and valleys of the product are.

23 / evaluation

At the time, we were free cash flow positive. But I think what we felt was once these generative models started to get very good, we sort of felt a lot of what we built was not as valuable.

24 / commitment

There was a crazy stat that I think people would find surprising, but we've saved over half a million dollars of SaaS products we were going to buy because our go-to-market team has now built apps instead of buying them.
