Growth Is a Search Problem

You start in fog, on a dark map, with an objective and no knowledge of which direction is uphill. The craft has always been a loop: hypothesize, move, observe, update. Hill climbing is one part of that loop. It can take you to a local peak, or up the wrong mountain if the proxy is wrong. One company optimized registered users. Another optimized people who actually came back.

AI changes the economics of the loop, not the geometry of the terrain. Agents can analyze, propose, ship, and interpret. You can now climb the wrong hill much faster. A rigid roadmap assumes the order of tests matches the size of the opportunities. Bandits waste less traffic on losers. A better strategy spends a small slice of budget mapping lever sensitivity first: poke the map, then climb where it makes a difference.

The Job Is Bigger Than the Record

The bullish case for incumbents is that AI makes systems of record more important, not less. Pipe the data into a general agent and skip the AI-native app. Claude becomes the front door. Salesforce still owns the CRM. Incumbents are also moving from storage into action: reviewing contracts, routing tickets, building campaigns.

The argument is partly correct. It is also incomplete. A contract is not the legal matter. A ticket is not the resolution. The job crosses applications, teams, and companies. A general agent can reach across tools, but access is not competence. Latency, inconsistent entities, and information held by other parties still block the full job.

Before 0 to 1 Comes -1 to 0

Most founder folklore starts at launch. The harder stage is earlier: figuring out what is worth the next decade. In isolation it feels like a squiggle. Talent makes it worse, because every capability is one more path that must be ruled out.

The old advice was to raise and throw things at the wall. That is a weaker bet now. Software has already eaten the easy fruit. AI makes it cheaper to build and easier for thin traction to become a local maximum. A low-conviction fundraise can consume years.

Dams, Not Moats

A common claim is that the flood of frontier intelligence will drown the application layer. There will be no moats left to build. That framing is incomplete.

Moats are useless against a flood. What matters are dams and waterways: systems that direct intelligence toward crops, reservoirs, and homes that would not otherwise receive it. Intelligence is a utility with unbounded demand. The world does not want raw models. It wants problems resolved and outcomes achieved.

Eighty Strategies that create Edge

Successful organisms, products, organizations, and networks overcome competitors by developing strengths along specific vectors. Often the advantage comes from an unusual combination of strategies rather than excellence on a single dimension.

This note catalogs roughly eighty such strategies, drawn from both biology and business, and grouped into categories: Accumulation, Price, Time, Uniqueness, Offense, Defense, Deception, Timing, Accreditation, Collaboration, Speed and scale, Ease, and Transformation.

The AI Bubble Is in the Earnings

Most discussions of an AI bubble focus on valuations. The more important risk may be the quality of the earnings those valuations rest on.

Reported profits across parts of the AI stack are being supported by a dense set of interconnected mechanisms. Large fiscal deficits and cheap capital boost demand that can look organic. Circular financing routes investor capital into startups that then buy the same investors’ hardware or cloud capacity. Accounting choices extend depreciation lives, capitalize R&D, and lean on non-GAAP adjustments. Buybacks and high operating leverage amplify earnings growth. Some demand reflects inventory build and defensive capital spending rather than immediate end-user pull. Subsidies and favorable financing terms further improve reported returns.

Lighthouse or Landgrab

AI companies selling into the enterprise face a basic choice between two go-to-market strategies.

Lighthouse applies when the product enables new work with no clear precedent. Buyers are taking a high-risk leap. They need social proof from prestigious customers before they move. Sales are high-touch, founder-led, and slow. Early logos matter because they reduce perceived risk for everyone else.

Own Your Intelligence

Over the next five years, every company will use AI either to run critical operations or as part of the product it sells. In both cases, generic intelligence will not be enough.

Off-the-shelf models are useful because they are general. But the deeper AI is embedded into a business, the more company-specific details matter: policies, workflows, risk tolerance, escalation rules, historical patterns, and customer context. These specifics do not live in a generic model’s weights.

Intelligence Is Becoming Abundant β€” What Happens Next?

Fifteen years after Marc Andreessen declared that "software is eating the world," we are entering the next phase: intelligence itself is becoming abundant and nearly free.

Just as information became abundant through the internet, expertise and judgment β€” the scarce resource that was locked inside trained professionals β€” is now descending the cost curve at extraordinary speed. This descent is happening on two compounding curves at once: cheaper hardware and more efficient models. The result is that high-quality reasoning, once expensive and rationed, is rapidly becoming a commodity.
