From Knowing to Doing

Most FinOps teams have a sense of where the savings are. The real challenge is getting the right decisions made, by the right people, at the right time – and sometimes, getting anyone to act at all. That’s where we come in.

Immediate
Savings

The savings that require the least effort and no technical changes come first. Results show up in weeks, not quarters and they fund everything that follows.

Lasting Change

Cost management becomes part of how your teams work. We help you build the data foundation, documented procedures, and decision-making habits that stick and prepare your organization for the next wave of AI and automation.

Governance

Simple frameworks for commitment decisions, cost accountability, and cross-functional alignment between Finance, IT, and Business.

Transparency

See who’s spending what, where, and why across business units, platforms, and cost categories. Give leadership a clear metric to assess whether cloud costs are a problem worth addressing.

What our clients have to say

"We had the technical knowledge but not the FinOps depth and resources. One decision, made confidently, cost us €2.4M. Having Kostner identify it in week one changed how seriously we treat this."

"We could not have accomplished what we did in such a short time without Kostner's support. And the best thing is that we are now fully capable of handling this internally going forward."

"We assumed this would take months to show results. We saw savings in the first billing cycle. It more than covered the engagement cost."

"We vibe-coded a FinOps tool based on FOCUS-data and quickly saw the gaps to Kostner’s high quality data with external benchmarks. This is something we cannot replicate, as we cannot replace the experience they transfer from other companies."

How We Work

One profitable step at a time.

Each step pays for the next — so you avoid overengineering, stay safe, and build the internal evidence your team needs to secure resources and authority for what comes next.

Month 1

Assess and save

We start with a structured assessment of your cloud environment — where costs sit, what can be saved immediately, and what requires more effort. Quick wins are identified and executed during this month. Results show up in your billing data, not just in a slide deck.

Month 2-6

Build the practice

This is where we help you shape a FinOps capability that lasts. We formalize policies and procedures, build the management reporting your leadership needs, and make sure your team has a clear roadmap, with savings initiative at every step. Every cycle ends with results your team can point to.

Ongoing

Own it and keep going

The engagement succeeds when your team can run this without us. In practice, there’s always a next layer of savings and improvements. We work alongside your team to transfer knowledge and build confidence for what comes next.

We work with enterprises managing million-euro cloud portfolios who want sharper cost control without adding headcount.

Why Kostner

We have a single KPI: helping your organization reduce and take control of its IT costs.

DIY

Your team is smart but without dedicated FinOps depth across enough engagements, the path to expertise is long. Every month spent figuring it out is a month of missed savings. And your cloud provider is the only one who benefits from you taking longer.

Big consultancy

Impressive slide decks, but the implementation is still yours. The team assigned often lacks hands-on FinOps depth and general consulting experience doesn't translate to knowing which levers to pull in your specific environment.

Kostner

We bring experience across 100+ enterprise engagements, proven tooling, and fast execution. We identify opportunities and execute on them together. We don’t leave until your team has the skills, data, and processes to run this without us.
