Monetize 2026: The Stripe conference for leaders shaping AI pricing (Sponsor)

  • Michele Catasta, President and Head of AI, Replit

Headlines & Trends

Startup Founders Are Working Harder Than Ever to Keep Up With Their AI Agents (6 minute read)

Founders have long put in long hours in the name of building the next big thing, but AI agents are pushing this to the next level. AI agents' growing capabilities and the speed at which the models powering them are evolving are causing founders to work more and more as they fear missing out on precious hours of work. This is causing erratic sleep schedules, a struggle to focus on anything but work, and the feeling that, while the pace is unhealthy and unsustainable, they just can't stop.
Will the DOJ's investigation into a16z spook other VCs? (7 minute read)

The DOJ has spent close to a year on an antitrust probe of Andreessen Horowitz, and the subject is board seats like the ones your own investors hold. Regulators are looking at partners sitting on boards of AI companies that now compete, with Ben Horowitz at Databricks and Martin Casado at Fivetran named as examples. If firms respond by giving up seats or declining them, board composition, information rights, and term sheets change for anyone raising now. Nobody outside the probe knows what the underlying allegations are.

Strategies & Tactics

Building a semantic layer: What it is and how we did it at PostHog (7 minute read)

A semantic layer is a dictionary of definitions that agents and humans read from. It doesn't copy data, replace a warehouse, or move a single row of data. It sits on top of the data that exists and describes it. The semantic layer gives everyone a single place to read definitions from so that the team is on the same page. This post tells the story of how PostHog built a semantic layer into its context warehouse.
Build vs Buy When Building Just Got Cheap (17 minute read)

For most of the last two decades, building a custom alternative was rarely worth it. That's now changed - building something fitted specifically to your company is now cheap. However, what hasn't changed is risk, security, and total cost of ownership. The reasons to not build auth in-house are still the same as they always were.

The X Ads MCP (1 minute read)

The X Ads MCP allows users to create ads directly from where they already use agents. Users can connect Grok, Grok Build, Claude Code, or other AI agents directly to their X Ads accounts and manage campaigns through normal conversation. Agents can pull real campaign data, analyze the results, and tell users what's working and what's not. The AI can create and manage campaigns, search interests and locations for targeting, add or remove targeting, create ad posts, promote existing posts, check campaign performance and reach, and update and activate campaigns. There are 23 X Ads tools available through the MCP.
Skills for your whole team are here (2 minute read)

Notion skills teach agents how teams work so they don't have to start from scratch. Users can ask Notion Agents to turn teams' work into skills that can be shared. Skills are Notion pages. Users can add processes, examples, references, and preferred formats, then share them like any other page.

Why your local LLM feels dumber than it is (15 minute read)

Plenty of teams save money running open AI models on their own hardware, shrunk to fit. Someone on a forum tested those shrunken versions of one model and logged 44.8 terabytes of results. Same model, same question. Right answer on one graphics card, wrong answer split across two, right again across four. One common compression setting quietly broke the model's ability to call outside tools, while a slightly bigger one worked fine. A feature that flakes in production but sails through your demo may be a settings problem, not a code problem. Answers also drift deep into long documents.
How the GTM playbook has changed in 2026 (13 minute read)
