00 ·About · Applied AI Studio · NYC
Practice over theory. Production over prototype. Operating systems, not opinions.
Praxis is an applied AI studio building production workflows for small and mid-market companies. Founded by Marc Kleinmann, based in New York.
Praxis is an applied AI studio for small and mid-market companies. Marc Kleinmann runs Praxis, as founder and sole operator, from New York, under the legal entity v1r2al Inc.
Praxis builds production AI systems. A workflow gets designed, built, and run on the client's own stack, then handed to the client's team to operate. One accountable builder carries that from the first conversation to the handoff. The public example is the breach-scan automation built for a cybersecurity legal practice, where a daily review that cost each attorney two hours became a fifteen-minute read.
Marc founded Praxis after a decade building consumer and creative businesses, including VIRTUALhaus, a 3D marketplace for building products. AI entered his practice in 2019 on that work. Praxis is where that turned into a focused applied-AI practice for operators.
01 ·The Practice
Every engagement ships a runnable system.
A Starter build drops in a workflow we have already built and proven. A Standard build fits one to how you actually work, discovery included. A Pro buildspans several tools and teams. Every build ends on the client's stack with the same output: working software, written runbooks, accountable handoffs, and a managed monthly that keeps it running.
The work sits at a rare intersection. Deep specialization in the Claude ecosystem (Cowork, Claude Code, MCP, Skills, Subagents, Projects, Agentic OS) gives Praxis architectural depth most generalist AI consultants can't match. Wide assembly range across n8n, Apify, Gemini, and creative AI for image, video, and voice means the solution gets built from the right tools, not the only ones the consultant knows. A decade of founder experience behind every build means the question driving the work is always does this change how the business operates?, never does this check a box?
Praxis is founder-led on purpose. SMB owners spending $5K to $35K on a single engagement need to know who's on the other end. One accountable builder, one decision point, one handoff, no subcontractor chain, no account manager layer. The brand and the founder are currently indistinguishable, and that is the point.
02 ·The Name
Pi · Praxis monogramPraxis comes from the Greek πρᾶξις. The act of doing.
Aristotle separated three modes of human activity. Theoria is thinking about. Poiēsis is making for its own sake. Praxis is the mode for people who combine thought and action into practice. That is the work.
There is a second thread. We are in the era of practicing AI, not planning it. The technology is mature enough to build on. Every month, "strategic AI roadmap" becomes less useful than one actual system running in production. Praxis names that moment.
03 ·The Founder
Marc Kleinmann.
Founder of Praxis. Decade of founder experience across consumer and creative businesses. Now specializing in applied AI for SMB owners and operators, working out of New York on the ET timezone.
The work is hands-on. We design the system, wire the automations, write the runbook, train the team, and make sure the thing runs without us. That last part is the job: a system the team operates after the engagement ends.
04 ·How we work
Six principles that hold across every engagement.
01Applied over theoretical.
Every engagement ships a system, not a strategy deck. The output is measurable change in how the business operates.
02Depth plus range.
Deep on Claude so the architecture is right. Range across n8n, Apify, Gemini, and creative AI so the solution gets built from the right tools for the workflow, not the only ones we happen to know.
03One builder, one accountable partner.
We own strategy, design, build, and handoff. No subcontractor chain. No account manager layer. The same person who sold the engagement ships it.
04Fixed price by default.
Three named sizes (Starter build, Standard build, Pro build). Price you know before signing. The scope work happens before the engagement, not during it.
05Stack-native.
Every system is built on your stack, integrated with your tools, and operated by your team. Praxis does not run hosted infrastructure on your behalf. The handoff is real.
06Craftsman, not crusader.
Praxis does not run on decade-stakes urgency rhetoric. Calmly confident: this is the work, here is what gets shipped, here is what it costs.

06 ·Common questions
What Praxis is, who runs it, and what it builds.
What is Praxis?
Praxis is an applied AI studio for small and mid-market companies, based in New York. It designs, builds, and ships AI workflows that run inside a business, on that business's own stack. The legal entity is v1r2al Inc.
Who runs Praxis?
Marc Kleinmann. He founded Praxis and is its only operator. The same person scopes the engagement, builds the system, and hands it over, working from New York on Eastern time.
What does Praxis build?
Production AI systems that the client's own team operates after the handoff, along with the runbooks that keep them running. The published example is a breach-scan automation for a cybersecurity legal practice, where a two-hour daily review per attorney became a fifteen-minute read. Praxis also publishes The Company Builder's Manual, a weekly newsletter for operators, at manual.praxisx.co.
There are several companies called Praxis. This is the one at praxisx.co.
This Praxis is the applied AI studio run by Marc Kleinmann in New York, legal entity v1r2al Inc. It is not praxis-ai.com, the digital-twin company. It is not praxis.co, the venture ecosystem. It is not Praxis Labs, praxiscompute.com, or the Praxis city project. It is not the Praxis teacher-certification exams.
