Online performance · since 2013
Online marketing
that adds up.
Online marketing only works when it's thought through economically. We run SEO, SEA, CRO, tracking, and AI as an integrated system — operated hands-on by the managing director, with measurable impact rather than reporting cosmetics.
By the numbers
No staged cases.
Four figures from daily operations.
Ranges from active mandates, not best-case showcases.
More budget isn't a strategy. Control is.
What we do
Services. One shared data foundation.
SEO, performance marketing, conversion optimization, web development and tracking use one shared data foundation. That keeps economic impact visible.
Organic reach that works in Google as well as ChatGPT, Perplexity and Claude. Sustainable, compounding.

Learn more ↗Conversion and web optimization as one connected craft. Hypothesis-driven, architecturally considered.
Learn more ↗Proprietary software
We don't use standard tooling. We build the tools ourselves.
Three proprietary tools are productively in use at Calvarius: Delta for feed management, picazzoo for AI creatives, GonzalAds for Meta campaign steering. Plus the ability to build custom SaaS components in a fraction of the previous time.
Proprietary tool
Delta — product data as a lever.
In e-commerce the performance question is almost always a product-data question. DELTA is our feed-management layer, built exactly there — versioned, platform-specific, no external license fees.
Proprietary Tool
Delta —
Product Data as a Performance Lever.
Most performance problems in e-commerce aren't channel problems — they're data problems. Delta is our feed-management layer: product data from PIM, ERP, and shop flows into a controlled pipeline, gets normalized, optimized, and prepared per platform — without Excel ping-pong and without a mapping layer on the client side.
- Clean, scalable product feeds — no SKU limit.
- Platform-specific optimization instead of one-size feeds.
- Versioned, auditable, without external license fees.

Companies we work with
Our work is rarely loud, but measurable. A selection of companies we have supported in recent years:
Engagements range from operational execution to strategic sparring and coordination of external partners.
Proof
Three numbers that precisely describe our daily work.
No staged hero cases. Three figures that show what we stand for — verifiable through work with active clients.
Most of our mandates run for over five years. That's the economically most meaningful metric in an industry where agency switches often happen annually.
Over ten years of operational experience in performance marketing — before PMax, before iOS 14.5, before AI-driven platforms. We know the disruptions of recent years because we've lived through them.
We work with B2C and B2B companies across a range of industries — with a clear focus on e-commerce, complemented by SaaS clients.
How we think
Four principles you can hold us to.
No values posters, no mission statements. Just operating rules that make a difference every day.
We don't work in silos. SEO, SEA, CRO and tracking run on a shared data model — every action knows the others.
No client project starts without an audit. If the data isn't sound, every strategy is guesswork — and we'll say so.
No hand-off to juniors after the pitch. André Freier sits on every client account himself — by default, not as a premium upgrade.
We don't earn more when you spend more. That keeps the incentive on outcomes, not on media volume.
We don't earn more when you spend more — and that's by design.
Engagement
Let's talk about your performance.
If you want to know where your online marketing is currently leaving potential on the table – and how to change that in a structured way, we're happy to talk.
On equal footing — without sales pressure.
