HYPER-LOCAL, HYPER-CLOUD

AI agent work should live in private notes, drafts, and cheap experiments stay on the laptop, and once it's useful to someone else, work moves to shared docs, repos, or company memory.

AI'S VALUE CAPTURE PROBLEM

Imagine an AI claims assistant watching every override an insurer makes. It does not just learn policy text. It learns when the company bends the rule for a broker, when a fraud pattern gets escalated, which underwriter gets trusted, and which ugly edge cases become paid claims. That is the enterprise AI value-capture problem here. The most sensitive company knowledge may live in exception logs and decision traces, not PDFs. For founders selling AI into serious workflows, customer-owned memory, audit trails, and training controls are not compliance garnish.

THE REIGN OF THE MIGHTY CREATOR

Brands used to brief a campaign, buy distribution, and control the message. This piece is about what happens when that center breaks. Creators are becoming the people who make the format, hold the audience habit, and decide how a product enters culture. That is different from an influencer post. An influencer rents attention for a launch. A creator can make the product part of a recurring world people already follow.

HOW TO WRITE AN EMAIL

Emails need to be clear so readers can understand the point in seconds, decide quickly, and forward the message without extra explanation. A good email makes the reader understand the point fast without trying to sound smart, warm, or impressive. Don't use emails for long back-and-forths - call or chat when speed matters more than recordkeeping, then send a short email summary with the decision. Make the next step obvious, so the receiver knows what to do.

COMPANY CULTURE AT SCALE

Mercury has kept its company culture strong as it scaled by following four high-level ideas. Be weird: the core of a strong company culture is how authentic and real everyone is. Keep doing things that scale. Be very careful with hiring executives and leaders because culture is a very top-down phenomenon. Embed company culture into processes to organically help perpetuate the culture.

THE TASK ECONOMY - DATA WILL BE THE NEXT $1 TRILLION CATEGORY

The Task Economy is the defining market for the future of AI. The barrier to automating every task with agents is covering the full distribution of all of the apps, all of the environments, and all of the tasks that correspond to everything in the economy. This will require a massive data build-out across every professional domain, academic discipline, and consumer use case. Labs, AI app companies, and enterprises will all fight to rapidly scale this data infrastructure across the full surface area of economically useful work. The ones that succeed will continue to improve frontier capabilities and gain market share.

WHAT A FOUNDER WHO SOLD HIS LAST COMPANY FOR $780M IS UNLEARNING

The founder who sold Vungle to Blackstone for $780M explains why his second-time playbook is a tax, after watching Blazel's token bill pass $70K in a single month and its AI-agency business race toward an easy but fatal $10M ARR. He kept the agency just long enough to harvest labeled human edits, fine-tuned a model on them, and pivoted to a platform before the cultural switching cost made the pivot impossible. The expensive lesson underneath it comes from Vungle serving two markets at once while AppLovin picked one, and today Vungle is worth $4B against AppLovin's $150-250B.

AGENTIC AI ADOPTION IS ON FIRE AT UBER

Agent AI adoption is changing how Uber builds. 99% of the company's engineers use AI tools. More than 70% of pull requests are attributed to agents. The biggest lesson that the company has learned is that the best AI opportunities are discovered by sitting next to the people doing the work, understanding every friction point, and building with them, not for them.

TIRED VS. WIRED: OUR DEEP DIVE ON WHY SOFTWARE SPEND IS UP RECORD AMOUNTS … YET HALF OF SAAS IS STILL DYING

Software spend is accelerating. However, valuations are collapsing for many software leaders. The software market has split in two: one group is tapping AI budgets and accelerating, and the other is running the same playbook from 18 months ago. This post breaks down where the line between these two groups falls and what moves a company from one side to the other.

THE EXECUTIVE AI LEVERAGE REPORT

53% of finance-room executives name proving ROI as the main blocker to further AI spend, 62% expect measurable return within six months, and 17% already fund AI partly from money that would have gone to headcount. Founders in the same network price 50% on usage and 18% on outcomes against 25% on seats, but they still sell through CIOs and business units while the CEO signs and finance carries the proof burden, which is where deals stall. If your product needs eighteen months to show value, you're selling to a buyer who wants evidence in six.

GROWTH FOUNDERS: HIRE A NEAR-PEER

Near-peers are people so good that the founder would be fine reporting to them if the roles were reversed. Their strengths perfectly complement the founder's strengths. Near-peers turn the founder's vision into daily operating decisions. This lets the founder focus on what only the founder can do, while the near-peer handles the rest.

IF NOTHING ELSE – SEGMENT CHURN. YOU'LL SEE PATTERNS AND LEARNINGS YOU WOULDN'T OTHERWISE

Segmenting churn into categories allows founders to separate different churn problems and solve them individually. Keeping big customers happy is different to keeping small businesses from seeking a cheaper tool. Instead of excluding trials and POCs, segment them out and figure out how to convert better. Also, segment NPS and CSAT per segment - double down on the happiest segments and the segments growing the fastest.

WHEN YOU BECOME THE PRODUCT

Successful creator businesses often evolve from selling content to selling access to the creator's judgment and expertise. Structure access through content, workshops, communities, and premium advisory services rather than offering unlimited founder availability. Founders who want to build a sellable company must gradually shift trust from themselves to the team, brand, and systems.

YOUR CHURN THRESHOLD IS A PRICING DECISION

Churn models ship with a default 0.5 threshold. This analysis prices that default at about $86 per customer in avoidable spend, $8.6M across a 100K-subscriber base. Missing a churner costs about 13x more than over-treating a loyal customer, so the profitable threshold sits well below 0.5 and the default is quietly setting your retention budget. Library defaults across an analytics stack are business decisions nobody consciously made.

ARE AI EMPLOYEES MORE EXPENSIVE THAN HUMANS?

Token prices fell from $60 per million to $0.60 in three years, and AI bills still exploded. A four-person startup ran up a $113,000 monthly bill from a single provider. Uber torched its entire 2026 AI budget in four months. Consumption is the reason. An agent re-reads context and checks its own work, burning 60 to 140 times the tokens of one reply. Track cost per completed task, not per seat, and keep the model layer swappable, because cheaper tokens do not mean a cheaper bill.

ENGINEERING THE OPERATING MODEL

Software architecture determines how software behaves. The engineering operating model determines how engineering behaves. Engineering organizations exist to create customer and business value through software. This means the job of engineering leadership is to maximize the value engineering teams create.

THIS IS THE NEW SAAS PLAYBOOK

Salesforce shipped Agentforce, the fastest-growing product in its history, and scaled it to $1.2B in ARR. The stock hit a 52-week low anyway. That paradox is the whole shift. When anyone can rebuild your headline feature in a weekend, the software surface stops being a moat, and value rotates to what you can't clone, the proprietary data loops, the right to move money or push code, and being the tool an agent chooses to call. Outcome pricing seals it, turning vendors into insurers who underwrite every result instead of billing for seats. So what do you own that stays scarce once building is free?
