Destigmatizing Mental Health in Entrepreneurship

5 days ago | feld.com | Brad Feld

I’m currently at the Global Entrepreneurship Congress 2025 in Indianapolis. Yesterday, at the end of the day, I spent several hours at High Alpha hanging out with my friends and then doing a Give First: The Power of Mentorship book event with them and about 150 people. One of the questions during the book talk was around mental health and entrepreneurship.
Vibecoding Prompts

A long time ago, in a galaxy far, far away, I was a CTO of a large, fast-growing public company. Well, I was a Quasi CTO in the same way the United States and the First French Republic had a Quasi War between 1798 and 1800 (basically, sort of a war; sort of a CTO … but not really.)As I rediscover my second love (my first love is Amy), I’ve relied on several mentors to help guide me. One of them is Michael Natkin, who has been helping me with Cursor in the background at a few key moments.
A Tweet, Vibe Coding, Jj, and Grok Walk Into A Bar

1 week ago | feld.com | Brad Feld

This played out on @bfeld on X, and I thought it was fun enough to replay it here for anyone who is struggling to get their minds around vibe coding and current AI tooling. If you are receiving this via email and the tweets/X’s aren’t showing, click through to the website as I’m still struggling to get Mailchimp working well after my hibernation. Perhaps it’s time to switch everything to WordPress…It started with this tweet (yes, they are still tweets to me).
Give First - Table of Contents

1 week ago | feld.com | Brad Feld

As a voracious reader, I love a good table of contents (TOC) as the roadmap to a book. While fiction is often structured as Chapter 1, Chapter 2, Chapter 3, … Chapter N, some of the best fiction writers are creative with their TOC. Any non-fiction author who doesn’t provide a detailed table of contents TOC is missing an opportunity to help the reader understand the book’s flow before they begin reading it. Below is the Give First: The Power of Mentorship TOC.
Beware the Grinfuckers

I did a talk with a private community of 100 GPs and investors in venture capital called Aces last week. It’s an off-the-record, confidential group organized by a few people, including Max Beaumont, who said I could mention him in this post. Max sent me the following summary. I asked him if I could post it, and he said yes. Thank you again for taking the time to join us yesterday, and for staying well past the scheduled end.. I could tell how meaningful the conversation was for those who stayed..

2 weeks ago | feld.com | Brad Feld

Registration for the Venture Deals Summer 2025 online, self-guided, free course by Techstars and Kauffman Fellows starts today. It’s based on the book Venture Deals: Be Smarter Than Your Lawyer and Venture Capitalist.

Venture Deals is now in its 4th edition and has continued to be a popular and helpful book.

2 weeks ago | feld.com | Brad Feld

On Saturday, May 31st, from 3:30 to 5:00 PM in downtown Denver, I’ll have a public conversation with Phil Weiser about various topics, including technology and innovation in Colorado.

Phil’s blog post Startup Community Leadership discusses many of the things he’s done to positively impact the Colorado startup community.
Turn Every Page - Feld Thoughts

2 weeks ago | feld.com | Brad Feld

I learned how to do deals from Len Fassler. Last week, I got an email from Dustin Kloempken, who sent me a few quotes he wrote down from the Berkshire Annual Meeting. One of them jumped out at me. “Turn every page. One important ingredient in the investment field that very few people do. And those people who did read every page aren’t telling you what they learned. You have to read every page.“In 1996, I was sitting in a law firm conference room in NYC next to Len.

3 weeks ago | feld.com | Brad Feld

I’m going to have a Random Day on 5/28 at The Composition Shop in Longmont. I plan to be there from 11 am to 5 pm with a break for a lunch meeting from 1 pm to 2:30 pm. We will have copies of Give First: The Power of Mentorship in the store on sale, even though the book’s official release date isn’t until June 24th, because my Colorado friends get special bonus early bird stuff. I have nine random day slots (15 minutes each), and I’ll hang out between them for anyone in the bookstore signing books.
Back in Boulder - Feld Thoughts

3 weeks ago | feld.com | Brad Feld

As a proud early Gen Xer, I was in high school when Back in Black came out. It was my favorite song for at least a week, and it’s still in my top 10 (something by Rush likely displaced it.) As a teenager, I knew everything about AC/DC (at least everything you could know before the Internet existed.) I wandered around that week proudly telling everyone who would listen that the song was a brilliant tribute to Bon Scott.
