THE END OF INTERCHANGE

The interchange fees that make up much of the cost of the credit card system are eventually going to go away. The interchange fee model is vulnerable to disruption from stablecoins, bank-to-bank direct payments, Pay by Bank platforms, and cryptographic identity layers in ACH. It is still an open question whether stablecoins or retrofitted ACH/bank rails will win, how fraud and reversibility concerns will be addressed, and what the timeline is for meaningful interchange compression.

THE TOP REASONS I SAW CROS FLAME OUT THIS YEAR

CROs can't just be managers with playbooks. To be successful, they need to be closers who learn, leaders who show up, and executives who stay when it gets hard. They need to personally close deals and be familiar with products, as well as understand their partner channels. A good CRO visits their major teams in person because they know that culture gets built in person and trust is earned face-to-face.

THE LAWYER MOST B2B STARTUPS DON'T REALIZE THEY NEED UNTIL FAR TOO LATE

Startups that bring on contract counsel generally see their overall sales cycle reduced. Founders signing at least two enterprise contracts a quarter should consider bringing on contract counsel. It will save the startup money and often help close deals faster. Having counsel will help startups avoid ending up with terms that let customers take advantage of them or create problems later down the line, like during an acquisition.

DESIGNERS OF PROBLEMS WORTH SOLVING

The best founders aren't solving obvious problems - they're designing problems worth solving. The distinction matters because finding meaningful problems may be more important than solving them. The approach involves reframing situations through expansion and elevation until the problem aligns the founder's purpose with how society and technology are changing. This lens helps identify founders who have the agency for entrepreneurship, even if their ideas seem "unfundable" by consensus standards.

SOFTWARE APPLICATIONS FACE A NEW INTERMEDIARY

Many years ago, Amazon tried to build its own device to escape Apple's control. AI companies now see personal devices as a way to escape the App Store tax and to own the user relationship. These companies don't want to live at the mercy of operating systems they do not control. Creating their own devices will allow them to own their own destiny rather than ask Cupertino for permission.

SOME THOUGHTS ON "HEAD OF NARRATIVE"

This essay explores why tech companies are suddenly paying $300k+ for "heads of storytelling" and whether it actually works. Anthropic is offering up to $400k for a "Head of GTM Narrative." The author's skepticism comes down to one thing: companies are extensions of their founders. Public perception of Anthropic is downstream of Dario, regardless of what a narrative lead says.
