Measurement isn’t hard because conversion rate is a complicated metric. It’s hard because the workflow is fragmented.

In a real ad campaign measurement workflow, you’re usually dealing with three problems at once:

1. The inputs are scattered across warehouses, files, and internal systems

2. Making them usable means figuring out how they connect (schemas, joins, definitions, mismatched labels)

3. Even after you get the answer, it’s rarely shareable in a way other people can explore without recreating your setup

So a “quick” question turns into glue work: stitching sources together, getting the right environment running, and then redoing it all whenever someone wants a different slice.

A concrete example: ad campaign measurement across systems

In the walkthrough video below, we show one simple but common scenario.

The exposure and conversion logs live in Snowflake. The campaign context—labels, channels, and creative groups—lives in Google Drive. And the question we want to answer requires both:

Where are we seeing strong conversion performance, and when does frequency start hitting diminishing returns?

How Memex Web approaches it

Memex Web is built to solve this end-to-end: connect the sources, make sense of how they fit together, run the analysis in a real environment, and publish it as a shareable app.

Here’s the flow:

1) Connect your sources (without over-scoping access)

In the demo, we connect Snowflake in a couple clicks. Then we connect Google Drive, but with an important detail: to follow security best practices, we scope access to only the file we need (Campaign Metadata), rather than granting broad Drive access.

2) Describe what you want in natural language

Next, we use Genius mode to get a strong first pass, and we describe the app we want to build:

“Show conversion rate by frequency bucket, with filters for channel, publisher, and creative group.”

From there, Memex handles the heavy lifting: it writes the code, joins the datasets, and produces an interactive app you can review and tweak.

3) Run it in a managed environment

Instead of running locally or managing infrastructure, the app executes in Memex’s secure serverless compute. No provisioning. No dependency setup. No “it only works on my laptop.”

4) Publish it so others can explore it

Once the preview looks good, you can publish the app with one click. If you need restricted access, publish as a Private App. If you want easy sharing, publish it publicly—either way, others can explore the exact same analysis without setting anything up.

Why this matters

The goal isn’t just to answer one question faster. It’s to make ad campaign measurement repeatable: connect sources once, build the app, and share it so the next question doesn’t restart the whole process.
