FOUNDERS ARE COMING BACK TO RUN THEIR PRE-AI B2B COMPANIES. BECAUSE IT'S THE LAST STAND

Founders are returning to lead their pre-AI B2B companies as AI presents challenges, exemplified by Daniel Dines at UiPath and Aneel Bhusri at Workday. These companies face stagnant growth, evidenced by Workday's decelerating revenue and UiPath's guidance cuts, necessitating foundational rebuilds that non-founder CEOs struggle to execute. While founders' returns stabilize and rebuild the foundation, reigniting growth remains elusive, highlighting the unique role of founders in these transformations.

CYBER RESILIENCE ACT: 11 SEPTEMBER 2026 – KEY STARTING POINT FOR REPORTING OBLIGATIONS

Selling software into Europe now comes with a breach-reporting clock, and it starts this Friday. From September 11, any company selling hardware or software that connects to a network in the EU has to report an actively exploited vulnerability under the Cyber Resilience Act. The first warning is due within 24 hours of finding out, a fuller notification within 72 hours, and a final report within 14 days of a fix. Severe incidents follow the same 24- and 72-hour steps. There is no revenue threshold, so a five-person startup with one EU customer is inside the rule.

HITTING ONCE, HITTING OFTEN: THE ANATOMY OF A GREAT VC CAREER

A comprehensive dataset shows that around 38% of VC professionals have at least one successful investment, but only 3% hit ten or more successful ventures. Success correlates with skill, not luck, as the top 1% of VCs account for over half of all net profits in the industry. This concentration of success suggests that a few individuals drive most of the economic impact in venture capital.

THE COMING PRODUCT RETENTION CRISIS

Consumer attention is hard to win over because people crave novelty. People are so cognizant of AI slop that any sign of AI use can ruin an entire product. The upcoming abundance of products will mean there will be an infinite amount more supply than demand. This means average product retention will collapse.

INTRODUCING FLAT RATE CDN

CDN costs should be predictable, but viral launches, traffic bursts, or misconfigured routes sometimes turn an otherwise normal month into an unexpected bill. Vercel has introduced Flat Rate CDN for Pro teams to provide more predictable monthly bills. It has built-in spike protection and service tiers designed for different traffic profiles. Teams can now choose the CDN capacity that corresponds to their typical usage profile, pay a known amount monthly, and avoid surprise overages from temporary spikes.

THE NEW MOATS ARE THE SAME AS THE OLD MOATS

Consumer AI products built around single-player utility remain vulnerable to rapid switching as model performance changes. Durable advantage still comes from network effects, marketplaces, and platforms that become more valuable as more users join, transact, and coordinate.

FIRING UNDERPERFORMING EMPLOYEES (AT STARTUPS)

You've failed as a manager if someone is surprised they are getting fired for performance. Underperforming employees should have their performance discussed regularly before anything happens. If they still aren't performing after several weeks, have a lawyer create separation documents for them to sign, then offer them severance in exchange for signing the documents. Communicate the decision to the team with respect.

Early investors might not follow into Series A due to fund math, not a lack of confidence.
