Corp Dev Reads Desperation, Not Talent or Tech

Founders in trouble are often dismayed by how fast corp dev people can sense their desperation. You'll be less surprised if you remember this is all they *can* sense. They can't judge technology or talent. All they can judge is...

Relying on a Better Filter Improves My Decisions

I'm not a great judge of character, but fortunately my mistakes are nearly all in the same direction (accepting the bad rather than rejecting the good). So all I need is a second pass by someone with a tighter filter,...

Investors Will Dilute to Join YC for Mutual Gain

If you want proof of what a good deal YC is for founders, I just told a UK startup I've invested several million pounds in that I'd be happy if they wanted to do YC. I'd get diluted alongside them,...

Prioritize Startups Now; Future Cohorts Secure Growth

As long as all newly founded startups prefer your product, don't worry about competitors who can convince larger customers. You'll own all future cohorts of companies, and that's more than enough. Plus in practice you'll eventually convert the old cohorts...

Selling to Startups Beats Investor‑Favored Big‑Company Deals

A startup told me that one of their investors didn't like it that they were selling to newly founded startups, and wanted them to sell to bigger companies, who have more money. If investors tell you this, write them off...

Describe Startups with Verbs, Not Nouns, for Clarity

When describing a startup it's usually better to use verbs rather than nouns. Say what you do rather than what you are. Not because it sounds more dynamic, but simply because it's clearer.

Money only Threatens You when It Buys All Ads

Don't fear competitors who've raised a lot, unless you can say precisely how all that extra money is going to make them beat you. E.g. if ads are the only way to acquire users, and they can buy all the...

Startup Rebounds: From Stalled Growth to Resurgence

A year of smoothly exponential growth, and then suddenly it stops working. That has to be demoralizing. But the startup toughs it out, and five months later growth is back. https://t.co/tQM44KNJXY

Fund Startup Ops with Bond Interest, Not Dilution

I talked to a startup today that had been forced to take so much from investors and whose expenses were so low that they could put the money in bonds and fund their operations off the interest. I told them...

Fundraising Slumps No Longer Mean Failure

I met with a startup in the current batch who seemed demoralized because fundraising was going badly. Later I learned they'd already raised a million dollars. Fundraising going badly is not what it used to be.

Compressing Data for LLMs Equals Understanding and Innovation

I talked to a startup yesterday that had been forced to compress certain information to fit it into an LLM context window. But compression is understanding, and in the compressed form the information could be used for other, new things.

I met a startup today whose founders had previously worked at Coinbase and Scale. And Brian Armstrong of Coinbase had himself worked at Airbnb. I bet 3 "generations" is not the record though. Anyone know of a longer chain?

The reason (good) investors are more optimistic is that, for them, the outcomes are weighted. If you're just measuring percent correct, you win by predicting startups will fail. But if the outcomes are weighted, you look for big wins even...
