The session began by introducing the concept of problem-solution fit and emphasizing three core validation activities: problem validation, solution testing and behavioural alignment. Participants were encouraged to speak directly with target users to determine whether the identified problem is sufficiently frequent, urgent or costly; use early mock-ups or prototypes to test whether the proposed solution performs better than existing alternatives; and determine whether the proposed solution fits naturally into customers’ existing behaviour and practices.

The webinar then explored the types of evidence that indicate progress toward problem-solution fit. These included clear confirmation from customers that the identified problem reflects their real experience, engagement from early adopters who are willing to test prototypes or minimum viable products, and stronger commitment signals such as positive feedback or willingness to pay.

Participants were introduced to the idea that an early-stage start-up is essentially an experiment searching for a workable business model. The session therefore emphasized testing ideas before committing significant resources. Different areas of business risk were introduced through the dimensions of desirability, feasibility, viability and impact, encouraging participants to begin by determining whether customers actually want and value the proposed offering.

The webinar introduced an experimentation process in which participants identify and prioritize their riskiest assumptions, break their ideas into smaller testable hypotheses, conduct experiments, examine the resulting evidence and continuously revise their business model. The presentation emphasized that experimentation can reduce risk and uncertainty and support a more informed decision on whether to pivot, persevere or pause an idea.

A practical B2B experimentation sequence was presented, beginning with customer interviews and problem definition, followed by qualitative validation and early “smoke tests,” and progressing toward stronger commercial commitment through letters of intent or paid pilot testing. Participants were encouraged to establish clear success and failure criteria before undertaking each experiment.

The session used a refrigerated food and beverage distribution and logistics concept as a practical case example. Participants were shown how assumptions about high distribution costs and the potential benefits of improved cooling and logistics could be tested through customer interviews, market-interest testing, low-fidelity prototypes and commitment from potential customers.

The example then progressed through problem-validation interviews, a solution-validation test and a behavioural or commercial commitment test. Suggested evidence included customers ranking the problem among their most significant operational challenges, asking about pricing or trial participation, and signing letters of intent or providing inventory for a test.

The webinar concluded by reinforcing several key messages: entrepreneurs should speak directly with customers, use evidence rather than assumptions, use experimentation to reduce uncertainty, and approach entrepreneurial decision-making with the mindset of a scientist.
