Performance marketing × AI systems

I grow consumer apps with paid media, and build the AI that makes it faster.

Paid acquisition across Meta, Google, TikTok, Apple Search Ads and programmatic. I build agents with Claude Code and MCP that watch the spend, catch what dashboards miss and tell you what to do next.

Paid Media Pacing Agent

Every morning a paid media manager checks dozens of campaigns for the same handful of problems. This agent does it in seconds and ranks what to fix by the money at risk. Pick a scenario and run it.

Estimate. Token counts are typical for this agent; API list prices as of Nov 2026 (source). The Meta and LinkedIn APIs and MCP itself don't charge per call. A Claude subscription covers the same runs for a flat monthly fee.

Project 02 · LiveSubscription LTV & payback

What can you afford to pay for an install?

A subscription app only wins on paid if a user's lifetime revenue beats what it cost to get them. Move the levers and watch LTV, payback and your maximum CPI change. Example inputs, not any company's real data.

24-mo LTV / install–
LTV : CAC–
Payback–
Max CPI at 3x–
Cumulative net revenue per installCPIBreak-even

Model: paid users = installs × trial rate × trial-to-paid. Each month a share churns. Revenue is net of the app store fee, over a 24-month horizon.

Project 03 · LiveAttribution lab

Same installs, five different stories.

7,000 sample installs, five channels, five ways to hand out credit. Pick a model and see how each channel's installs and CPA change. Then switch on the geo-lift test to see which channels actually drove installs.

    Five hooks, one offer. Which ad actually wins?

    Five ads for Stridewell, a fictional fitness app at $12.99/month with a 7-day free trial. Same offer, same audience, $6K each on Meta over two weeks. Only the hook changes. Rank them by a different metric and watch the winner change. Sample results.

    Where should the next dollar go?

    Every channel gets more expensive as you scale it. Split a monthly budget across four channels and watch total installs and blended CPI respond. Then let the optimizer find the mix that buys the most installs. Sample response curves.
