SELECTED WORK · GREEN BEAR CONSULTING
Real assignments. Clear decisions. Evidence that changed the work.
I work with technology founders and leadership teams when the technology is promising but the commercial direction, priorities or operating model are not yet clear. These are recent assignments delivered through Green Bear Consulting.
FRACTIONAL OPERATING ASSIGNMENT
Action Engine / Aspen
Fractional Strategic Operator · AI, fleet intelligence and commercial validation · 2026
Action Engine had strong capability in geospatial data, telemetry and AI, but too many possible product directions and insufficient evidence about which problem customers would act on.
- Reframed the proposition from broad data-quality checks towards AI-assisted fleet investigation, prioritisation and action.
- Identified fleet operations and telemetry overload as a stronger commercial direction than generic platform positioning.
- Built a 90-day validation model with explicit assumptions, evidence thresholds and continue, pivot or stop decisions.
- Connected customer evidence to product priorities, demos, pipeline stages and commercial decisions.
- Worked directly with the founder and across product, engineering, UX and commercial stakeholders.
Outcome: clearer commercial direction and stronger operating discipline. Repeatable paid demand had not yet been established when financial constraints ended the engagement.
DEEP-TECH COMMERCIALISATION
NuNet / Undergryd
Fractional Strategic Operator · Agentic AI commercialisation and capital readiness · 2026
NuNet was developing ambitious infrastructure spanning decentralised computing and AI-agent orchestration. The challenge was turning broad technical possibility into a focused product, a credible commercial path and an investable case.
- Made the critical customer, product, market and investment assumptions explicit and testable.
- Explored agentic-AI infrastructure as a possible first commercial wedge.
- Connected product choices, go-to-market strategy and investor requirements into one evidence-based logic.
- Helped shape Undergryd’s emerging position as an open control plane for AI agents.
- Identified unresolved mandate, ownership, IP, resource and decision-right questions that blocked operationalisation.
Outcome: greater strategic and commercial clarity, including a grounded decision not to continue investing effort without the mandate and evidence required for execution.
FOCUSED COMMERCIAL REVIEW
HemmaPro
A focused assessment of a two-sided marketplace: its commercial model, customer demand, marketplace dynamics, assumptions, risks and priorities.
- Separated activity and encouraging signals from evidence of repeatable demand.
- Identified the assumptions and marketplace risks requiring validation.
- Converted the diagnosis into concrete recommendations and a structured path forward.

WHAT CLIENTS AND COLLABORATORS SAY
Independent perspectives on the work.
Jörn has been fantastic to work with. He brings a wealth of knowledge, expertise and insight along with an always-positive attitude, you will never have a bad day working with Jörn.
He throws himself into the work. On go-to-market he doesn’t stop at the surface-level playbook; he digs into the commercial model underneath it, who actually buys, why, what has to be true for the numbers to work, and then turns that into a sequence you can actually execute against.
What I value most is that he’s honest. Jörn will tell you what he really thinks about your positioning, offer or your assumptions, kindly, but without softening it into something useless. That’s rarer than it should be, and it’s exactly what you want from someone advising on GTM.
Any team building toward a market should want Jörn in the room.
Jennifer Bourke · Founder, ZERO ARC AI · Worked with Jörn on the NuNet/Undergryd team
Jörn has joined our team as a fractional operator, focusing on developing and exercising go-to-market strategies of the deep-tech product that we have developed over years. He is a seasoned strategy and operations advisor without reservations putting his energy, passion and expertise into the engagement and understanding it deeply.
At NuNet, in a few first moths of collaboration, Jörn helped us with creating clarity around commercial direction, validating assumptions through evidence, and connecting product, GTM and investor logic in an early-stage, ambiguous environment which is changing fast and in rather unpredictable manner.
From a founder’s perspective, it is a pleasure to work with Jörn. He is able to express his professional advice and opinions in a straightforward and honest manner, kindly but firmly. I am looking forward to further collaboration.
Kabir Veitas · Co-founder & CEO, NuNet.io
Jörn took the time to understand HemmaPro in depth and produced a thorough strategic assessment of our commercial model, marketplace challenges and priorities. He was able to identify important assumptions and risks, while turning them into concrete recommendations and a structured path forward. I particularly appreciated his ability to look beyond the product itself and challenge how the business could establish stronger commercial evidence.
