She will tell you when the data says the thing you want to build is not worth building. That is the point of hiring her.
She will not run a sprint to validate a decision the founder has already made. That is performance, not research, and the work is most useful when the answer is genuinely open at the start. If the work surfaces that customers do not want what the founder is planning, she will say so plainly, in writing, in the deliverable, even where the founder would rather hear something softer.
She will not produce a 40-page report. The brief is short on purpose, because the brief is the point.
She is also writing publicly about cognition, decision-making, and how humans function in AI-saturated environments. The view that runs through that writing also runs through her commercial work: understanding the brain is the most underleveraged tool in product thinking, and most teams are leaving real value on the table by not using it.
