The data other
platforms can't give you.

Not all data is created equal

Most targeting data tells you what people might want. Ours tells you what they actually spend money on.

Search & social ads
Intent signals, clicks, views
You know what people are interested in β€” not what they actually buy.
Loyalty programmes
Your own customer data
Only covers your existing customers. Blind to competitor shoppers.
Data brokers
Modelled & inferred data
Probabilistic. Often inaccurate. Privacy concerns.
Herm.io
Verified purchase transactions
What shoppers actually buy, across all brands. Zero-party, privacy-first.

Insights from real transactions

Our first-party purchase data gives you a genuine picture of shopper behaviour β€” verified, not modelled.

πŸ›οΈ

Purchase history

See what shoppers actually buy β€” which brands, how often, how much. This is transaction data from connected accounts, not modelled or inferred.

πŸ”€

Brand switching patterns

Track how shoppers move between brands in your category. Identify who's at risk of switching away from you β€” and who's ready to switch toward you.

πŸ“Š

Category spending trends

Understand how spending shifts across fashion, cosmetics, electronics, food, and more β€” by market and by season. Spot opportunities before your competitors do.

πŸ’°

Periodic spending analysis

See how individual shoppers' spending changes over time β€” total spend, category spend, and frequency. Identify high-value shoppers before they become obvious.

Your brand dashboard

Segment, target, launch, and measure β€” all from one interface. No integration required.

Segment by brands shopped

Unique to Herm.io

Create audience segments based on which brands shoppers have actually purchased from. Target your competitor's loyal customers, or find shoppers who buy complementary products.

Segment by periodic spending

Unique to Herm.io

Filter shoppers by how much they spend β€” overall and within specific categories β€” over any time period. Find high-spenders in your category who haven't tried your brand.

Real-time offer performance

Live dashboard

Track views, claims, and redemptions as they happen. See which segments respond best to which reward types, and adjust your strategy without waiting for a report.

Self-serve or assisted

Flexible

Build segments and create offers yourself in the dashboard, or let our team configure campaigns for you. Most brands start assisted and move to self-serve as they scale.

Better data doesn't mean less privacy.

Shoppers share their purchase data with us because we never share their identity with you. You see anonymised segments β€” shopping patterns, brand preferences, spending behaviour β€” but never names, emails, or personal details. When a shopper engages with your offer, the transaction happens on your website. You own the relationship. We protect their privacy. That's why the data stays high quality β€” because shoppers trust the platform enough to keep it connected.

A growing audience across Europe

We're currently live in three European markets with thousands of shoppers actively building their profiles. New members join daily, and every connected purchase adds more transaction data to our platform. As our audience grows, so does the precision and reach of your targeting.
