Prompting humans and machines. Be the best version of yourself.

[Caleb Peffer (Hiring!) @CalebPeffer]

Excited to announce @firecrawl's $14.5M Series A 🔥

We've grown 15x in the past 12 months. The demand for clean web data in AI is real.

Here's the story of how we built the web data layer for AI - starting from a side project to powering how 350k+ builders get web data 🧵

[Caleb Peffer (Hiring!) @CalebPeffer]

@WillManidis supply and demand.

10x easier to learn, 10x less valuable when AI can do it for you

[Caleb Peffer (Hiring!) @CalebPeffer]

@scaling01 I don't think anthropic is profitable

[Caleb Peffer (Hiring!) @CalebPeffer]

prompt hack for negotiation - try to see what the person across the table sees

if you're sending a customer a proposal:

🚫Don't: Claude, give me feedback on this customer proposal

✅ Do: Claude, a vendor just sent me this proposal - what should I be concerned about?

@garrytan Firecrawl is building the thalamus

[Firecrawl @firecrawl]

Firecrawl ranked 1st place for agentic search on Devtool Arena.

We meant it when we said Firecrawl was built for AI agents.

See the full results: https://t.co/vQrPJKfSnP

[Caleb Peffer (Hiring!) @CalebPeffer]

Something is cooking

[Firecrawl @firecrawl]

The web wasn't built for AI agents. So we built Firecrawl.

- /search finds fresh, relevant sources from the web
- /scrape turns any URL into clean context for AI
- /interact automates clicks, pagination, and logins

Join 1,000,000+ developers connecting intelligence to the web.

this is smart. save your context - maybe one day you'll be able to sell it

Or it will be too valuable to sell

The Context Acquisition Company (CAC).

We are a holding company acquiring services firms for their tokens in order to build domain specific agents/ models to deploy into our platform businesses and beyond.

There's $1T hidden in the computers. We're gonna get it out.

[Caleb Peffer (Hiring!) @CalebPeffer]

Do the math folks!

[Nicolas Camara @nickscamara_]

One html page on avg produces 36k tokens. With proper md conversion you cut that down to 2.8k tokens. That’s 92% cost reduction

While I agree that some cases HTML is better, by no means it’s a cost viable option for 99.9% of users

You literally save $1,079* if u fetch 10k pages

Most VC backed startups die. The ones that win change the world

Many - but not most - bootstrapped businesses survive. almost none change the world

your choice, anon

[Julien Active @Julien4Future]

@CalebPeffer Survivorship bias. For every unicorn, dozens of VC-backed startups burned billions extracting from LPs. I build for sustainable margins, not Series D valuations.

[Caleb Peffer (Hiring!) @CalebPeffer]

@JYukariHero VCs do remember, they have every failure on their balance sheets

and they still make money. thats the point.

[Caleb Peffer (Hiring!) @CalebPeffer]

Depends on what your definition of "best" is: a Base hit, or a "slam dunk home run change the world outlier"

if you want #2, venture is typically the best option

if you wanna build a good enough business than bootstrapping is better

[Caleb Peffer (Hiring!) @CalebPeffer]

People talk about chasing profitability like it's "prudent" thing to do

Its not. it just means you're company is focused on extracting, not innovating

That's why the venture model has consistently changed the world - and bootstrapping hasn't

I love this idea from @jasonfried

"Your only competition is your costs."

Keep costs low, keep the team small, make stuff you want to use. You don't need the whole world:

“A business is very simple. You got to make more than you spend. If you're making more than you spend, then your competition is your cost.

That's what you're really in business against, how much it costs you to stay in business.

It's not all the other alternatives that are on the market.

You can't control what they're going to put out there, what they're going to price it at, all the things they're going to do. They're going to do what they're going to do.

What I can control is how much it costs me to run my business, how much I sell my product for, and as long as I make more than I spend, I get to stay in business.

And isn't that what this is all about, staying in business?

That's what it's all about because I like this. I want to keep doing this. I can't keep doing it if I don't stay in business.

I can't keep doing it if I make less than it costs me to make the things that I make.

So I'm always thinking about the only competition I really have on an annual basis is to make sure that we make more as a company than it costs us to run the company.

That's my real competition.”
