Where Commercial Strategy
Meets Engineering
Since 2016, we have delivered the technology that companies run on. Our work began with real-time platforms for technology companies in Berlin and Lisbon, including one of the first products for hosting large events online. Over time, our focus moved to the core of the business: the systems that generate revenue, serve customers and keep operations running.
In 2022, that experience became CoderStein. Today we partner with growing companies across the USA and Europe to design, deliver and operate software, AI and automation. We measure every engagement the way our clients do: by the value it creates for the business.

Frequently asked questions.
Have a specific architecture or procurement question? Email max@coderstein.dev and we will respond within one business day.
How do you approach AI adoption without risking sensitive company data?
Our approach is governance-first. Before deploying any AI agent or workflow, we set strict data-access limits, configure zero-data-retention enterprise APIs, and add human approval for sensitive actions. When required, models and automation run inside your own private cloud.
Will you try to sell us software licenses or tools we don't need?
Never. Our engagements often consolidate platforms rather than add them. If an overlapping tool or unused license adds cost without return, we recommend removing it. Every recommendation is vendor-neutral, documented and approved in writing.
We already have an internal RevOps or engineering team. Can you work alongside them?
Yes. Co-managed delivery is one of our core strengths. We integrate with your existing tools, communication channels and planning cadence, extending your team's capacity rather than replacing it.
Are we locked into a long-term contract?
No. Most clients begin with a 1-week diagnostic audit or a fixed-scope engagement (typically 3–8 weeks) with clear milestones. Ongoing support runs on a monthly retainer with a simple 30-day notice period.
How do you support US and European time zones?
Headquartered in Lisbon, our working hours cover the full European business day and overlap with US East Coast and Central mornings. Meetings take place in your morning, and delivery progresses while your team is offline.
How do you protect our systems, and who owns the intellectual property?
We work under mutual NDAs and GDPR-aligned data processing agreements, with MFA-enforced named accounts and least-privilege access that is removed at completion. At handover, 100% of the code, workflows, documentation and IP belong to your organization.
