GREEN BEAR · JÖRN GREEN
Evidence for decisions too expensive to leave to assumptions.
I help funded B2B technology companies resolve commercial and operating uncertainty before they commit another quarter of runway, engineering capacity or investor attention.

WHEN TO BRING ME IN
The useful trigger is not “we need advice.” It is “this decision is getting expensive.”
The customer decision
We have a product, but we do not know which customer, problem or proposition deserves the next quarter.
The evidence decision
We have activity, pilots or investor interest, but not enough evidence to justify scaling or raising.
The execution decision
We know what should happen, but ownership, cadence and follow-through are not strong enough to make it move.

SEE WHAT THE WORK PRODUCES
The work becomes artifacts leadership can use.
Green Bear engagements do not stop at advice. They produce decision artifacts that make assumptions, evidence, risk and commitments visible.
DECISION BRIEF
What should we do now?
The decision, options, confidence level, evidence strength and decision rule in one usable brief.
EVIDENCE ASSESSMENT
Which claims are safe?
Claims separated into strong, moderate, weak and insufficient evidence before they become commitments.
PORTFOLIO RISK MAP
Where is the real constraint?
Company-level uncertainty, evidence quality, bottleneck and recommended next move made visible.

Field guides on leadership, operating systems, decision-making and emerging technology.
Inspect the work before you commit.
A Fit Call is useful when the decision is already clear enough to discuss. If you are still assessing the approach, start with the evidence below.
See a sample Decision Brief
See how a consequential choice is made explicit: options, evidence strength, confidence and the next move.
Read an operating case
See how commercial uncertainty was separated from activity in a live fleet-intelligence engagement.
Find the right intervention
Compare the Review, Sprint and Embedded engagement before deciding whether a conversation is useful.
What decision is becoming too expensive to leave unresolved?
Bring the decision. A Fit Call determines whether the right next step is a review, sprint, embedded engagement or no engagement.
