BUILDING FOR TRILLIONS OF AGENTS

Agents are no longer just chatbots with basic tools. They now have sandboxed environments and can write and run code for any problem they run into, interact with APIs and CLIs directly, and have their own file systems and long-term memory. These primitives offer a glimpse of agents that can handle any task that can be thrown at them. The future will see enterprises with thousands more agents than people in a company. As a result, agents will become the primary users of all software, which means developers should start considering what software to build for these agents.

THE SWORD OF DAMOCLES IN SOFTWARE

GitHub Copilot's early lead diminished as competitors like Claude Code and OpenAI Codex surged past 100,000 users within months. From 2022 to 2025, software companies' net dollar retention gradually declined, with a sharp drop in 2026. Companies with simple, easily replaceable products, such as Asana and Zoom, now face increasing threats, leading to potential contraction.

GET IN THE TOKEN PATH

Every AI workload ultimately boils down to tokens being generated, processed, and consumed by models. The companies that sit closest to the generation and consumption of tokens will be the ones whose revenue scales with AI activity. The winners of the cloud era monetized the core consumption primitive. That primitive is now tokens. Own the meter, and growth will take care of itself.

ON BEING LEGIBLE TO CAPITAL

Fundraising legibility breaks into three stages: exterior status, network positioning, and pitch dynamics. Founders outside the top two tiers (repeat founders, top-company alumni) need to build a public body of work, like open source projects or writing, to generate inbound interest. Warm intros from a handful of well-networked angels matter more than any deck, since being "in-network" means capital-adjacent people already vouching for you before the first meeting. In the room, the founders who close know their market cold and flip the power dynamic by making the VC feel like they are competing for the deal rather than doing a favor.

AVOIDING A CULTURE OF EMERGENCIES

Managers can reduce team emergencies by deeply understanding their team's tasks, setting clear priorities, and developing a strong mental model of the team's role within the company. Good managers proactively address potential issues, make informed decisions, and maintain a long-term focus on productivity rather than short-term gains. Prioritizing team well-being and clarity leads to higher productivity and improved talent retention.

THE HONEST REASON AI WILL BEAT MANY SALES REPS: THEY DON'T REALLY DO A LOT OF THE WORK. BUT AGENTS DO AND WILL

AI will replace the sales reps who weren't really doing the job in the first place. Great sales reps own their scheduling, run real demos, know the product, industry, and competition, and solve the actual problem. They follow up relentlessly and simplify deployment. The good reps will use AI to do even more work even faster. The reps that were coasting will be replaced by systems that do the work better than they do.

THE TASTE RANKINGS: WHICH VCS ACTUALLY HAVE IT

ADIN Research has identified a bug in OpenAI's GPT-4 API that exploits confidentiality issues. There are potential risks for users relying on the model for sensitive data processing. This issue prompts discussions on securing AI applications.

THE COWAN PARADOX

The Cowan Paradox, named after historian Ruth Schwartz Cowan's finding that vacuum cleaners didn't reduce housework but raised cleanliness standards and reassigned labor to fewer people, maps directly onto AI agents in B2B. A Berkeley Haas eight-month field study confirmed it: workers adopted AI, expanded into adjacent roles, stopped separating work from non-work hours, and ended up busier than before.

EVERY BIT OF EFFORT HELPS

Early-stage startup progress rarely feels linear, but the breakthrough usually comes from one more meeting, one more call, or one more feature pushed past the point where most founders stop.

AI MADE RELATIONSHIPS, NOT FEATURES, THE LAST DEFENSIBLE ADVANTAGE

Companies should build history, context, and trust by understanding their customers, measuring the right outcomes, and continuously improving the relationship through every interaction so that switching feels like starting over.
