## About this market
Project-based AI marketing, as documented here, means a scoped build dropped into an existing marketing stack. OstraconAI's Singa pipeline enriches, scores and routes inbound leads into HubSpot on n8n and Gemini, went live in week three, and cut manual lead sorting from 45 minutes a day to single-digit minutes; its Olo-apteekki web app generates campaign banners from real product images, taking a set from 20–30 minutes to near-instant. Found built Secret Sales a neural network predicting each product's 30-day sales value, rolled out on a slice of budget first and credited with 28% higher ROAS than the account's other Shopping campaigns; its project work also includes bespoke SEO and CRO test-and-learn projects. Ekimetrics is the measurement option, with marketing-mix modeling for Eurostar as its named case.

For a marketing team buying a project, the sorting question is who runs the build once the project closes. Most of these systems sit on tools you already pay for—HubSpot, n8n, Clay, Google's ad platforms—so ask who owns the workflows and accounts at handover, and who adjusts the prompts or retrains the model when the market moves. The curator notes that Found's data and AI work is credited to its sister company Braidr, that several OstraconAI headline figures are forecasts rather than measured results, and that Ekimetrics's detailed cases are anonymous; ask each for a measured result from a finished project, not a projection.

### How much does an AI agency cost for ai marketing?

### How is the project-based model verified?
