20+ companies started evaluating enterprise martech tools last week

Most won't get the deals because they have no idea these companies are actively buying

So necessary in the age of AI to have a tool that can monitor this for you, which is why I built Signal Sleuth

AI models are still only good at producing the 80% that require 20% of inputs. Yes sure you can cook up a MVP or mockup or first draft quick. But that...

AI models are still only good at producing the 80% that require 20% of inputs.

Yes sure you can cook up a MVP or mockup or first draft quick.

But that gap to something seriously good and valuable is still huge.

Sonnet 3.7 is the first time I feel a model is significantly dumber than its predecessor. Still using Sonnet 3.5 every day.

Eeeek, just hit send on probably the most vulnerable newsletter I've ever written.

It’s about what happened when I didn’t get diagnosed with ADHD…

…and what I learned instead about my brain, memory, spiraling thoughts, and the seesaw between focus and self-criticism.

Writing this stuff takes me so much time and energy, and I do sometimes wonder why I do it haha. But, something in me just keeps going.

Because this newsletter actually grew out of a deep frustration with myself:

• Why is my energy so low?
• Why is it so hard to focus?
• Why can’t I stick with new projects?
• And what’s up with this relentless, self-critical voice in my head?

I didn't need more hacks and couldn't stand the inspirational mindset fluff. I was looking for answers.

So I started reading. Learning. Testing. Writing.

About the brain. The body. The breath.

About nervous system regulation, neuroplasticity, and performance.

And I started sharing what I learned—one idea at a time.

Fast forward 3 years—92 editions and 2,700 subscribers later—and Stretch is still my favorite thing I create.

Today's edition was especially cathartic to write. It helped me make sense of my brain in a way I’ve struggled with my entire life.

And if it helps even one other person feel a little more seen or a little more understood? It's worth the time and energy x 100! (Except I just noticed 3 people have unsubscribed in the last 10 minutes haha oh man that does always sting a bit - I really shouldn't look at those stats 😂)

(PS the newsletter also includes a link to a free breath exploration workshop I'm running on April 10, so check it out if you're curious - it'll be a mix of experience and education, oriented toward day-to-day application)
