Research methodology, written honestly.

Practical notes on interview research — where AI moderation genuinely helps, where it doesn't, and how to think about sample sizes, saturation, and diligence calls.

Methodology

AI-moderated vs. human-moderated interviews: an honest comparison

Where AI moderation genuinely wins — parallelism, consistency, no scheduling — and where a skilled human still beats it. Ends with a decision framework, not a sales pitch.

Sample sizes

How many user interviews do you actually need?

The 5-user heuristic, what saturation really means, why the answer depends on segments and stakes — and what changes when interviews are cheap to parallelize.

Diligence

Expert interviews in due diligence: getting from 10 calls to 100

The traditional expert-network model, its cost and scheduling constraints, and how short AI voice interviews widen coverage before you spend human hours on the highest-value calls.
