Built for merchants, not data scientists

What is Flexsee?

Flexsee is an AI predictions platform for e-commerce and marketing. It connects to Shopify, Klaviyo, and Meta Ads so you can predict high-value customers, personalize recommendations, seed lookalike audiences, and track ROAS from one guided workflow.

Your store already knows who is likely to buy next — Flexsee makes that signal show up in the tools where you actually run campaigns.

Works with your stack

“We built Flexsee because exporting CSVs before every Meta launch is not a growth strategy — it's a chore.”

Connect once. Predict on your own orders. Activate where you already market.

Predict, activate, measure

The full loop — from signal to and results — without the spreadsheet middleman.

Predict

Train machine learning models on your catalog, orders, and onsite behavior. Surface who is likely to buy next, which products to recommend, and which customers belong in high-intent segments.

Activate

Push predictive audiences to Meta as custom audience seeds for lookalikes. Send personalized product blocks to Klaviyo flows. Launch and manage campaigns from the Flexsee dashboard when you are ready.

Measure

Track ROAS and campaign outcomes tied back to the audiences and offers you launched. See whether predictive targeting beats broad lists over time.

How it works

  1. 1

    Connect Shopify

    Install the app and sync products, customers, and orders. Add the optional web pixel for richer onsite signals.

  2. 2

    Train models

    Flexsee builds prediction models on your store data — no data science team required. Accuracy improves as order volume grows.

  3. 3

    Export audiences

    Send predicted high-value segments to Meta, recommendation payloads to Klaviyo, and audiences to Mailchimp. Use the API for custom stacks.

  4. 4

    Run & optimize

    Launch campaigns, monitor ROAS, and refine who you target based on what actually converts.

Who Flexsee is for

If you have a Shopify store and spend on paid or owned channels, you are exactly who we had in mind.

  • Shopify brands — spending on Meta or email and wanting audiences built from purchase behavior, not guesswork.
  • Growth teams — done with the pre-campaign CSV export ritual. Connect once, export when predictions refresh.
  • Developers — wiring predictions into custom flows via the Flexsee API.

Manage everything in one place

Connections, trained models, audience exports, and campaign tooling live in the Flexsee dashboard. Pricing and feature tiers are on the homepage.

Frequently asked questions

What is Flexsee?
Flexsee is an AI predictions platform for e-commerce and marketing. It connects to Shopify, Klaviyo, and Meta Ads to predict high-value customers, power product recommendations, and sync audiences for retargeting.
How does Flexsee work with Shopify?
Flexsee syncs products, orders, and customer data from your Shopify store, optionally enriched with onsite behavior via the Flexsee web pixel. You train prediction models on that data, then export audiences and recommendations to Meta Ads and Klaviyo.
Does Flexsee replace Klaviyo or Meta Ads?
No. Flexsee is the intelligence layer: it predicts who to target and what to recommend, then sends those signals to Klaviyo for email flows and to Meta for custom and lookalike audiences. You still run campaigns in those tools.
Is Flexsee free to try?
Yes. Sign up at dashboard.flexsee.ai with no credit card, connect Shopify, and start on the free tier before upgrading for more prediction volume.
How is customer data handled for Meta audiences?
When exporting to Meta, Flexsee sends hashed identifiers (such as email or phone using SHA-256) as required by Meta Custom Audiences. You control which integrations are enabled and can disconnect them anytime. See our Privacy Policy for full details.
