Why we picked it
The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

- Talk about their life, not your idea.
- Ask about specifics in the past, not opinions about the future.
- 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

A tight, practical breakdown of what a concierge MVP is actually testing, using the Food on the Table example step by step. It makes the key point that the personal service is not the product, it is a learning activity aimed at your riskiest assumptions. Read it when you want the concept explained clearly without a book-length commitment.

The two ways to fake a product while you test real demand. Do the work by hand in the open (concierge), or hide the manual work behind a front so users think it is automated (Wizard of Oz, the way Zappos started). Clear examples of when each one fits.

- Concierge is transparent, Wizard of Oz is hidden.
- Both let you sell before you build.

Why we picked it
This is the cleanest short explanation of the two manual-first MVPs and, more importantly, how they differ, which is where most founders get confused. Concierge means you are the visible front end doing the work by hand, Wizard of Oz means you have a real interface but a human quietly runs the back end. It walks a single concrete product example through both, so you can see which one actually answers the question you are trying to answer.

Mind the Product
by Amanda White

- Concierge MVP: no interface yet, you personally take inputs and deliver the result by hand, and the user knows it is manual.
- Wizard of Oz MVP: a real front end that users think is automated, while humans do the work behind it, useful for testing whether people will use the interface itself.
- Pick based on what you need to learn: concierge tests whether the service is wanted, Wizard of Oz tests whether the product experience works before you build the automation.

Kromatic works with corporate and startup teams on lean experiments, and this piece is precise about the difference and the failure modes of each. It helps you avoid the common trap of building fake automation when a simple human-facing service would answer the same question faster. A solid second read once the basic distinction has clicked.
From
Kromatic
- Do not build fake automation if a manual service will do.
- The user's awareness is the whole difference between the two.
- Design the test around a single assumption you can falsify.

It frames customer discovery as testing your assumptions against real people rather than defending a plan. A short, foundational read on why you are doing this at all.

The permission slip to recruit users by hand, do things manually, and deliver 'insanely great' experiences to your first few customers. The cheapest, most honest way to validate demand is to go get it one person at a time.

- Recruit your first users manually, don't wait for them to come.
- A tiny group of users who love you beats a big group who like you.

If you do not want to read the whole book, this is Ries in his own words defining the MVP in a few pages. His guiding rule is to strip out anything that does not add to the learning you are after, which is exactly the logic behind delivering the outcome by hand first. It is a fast way to get the concept straight from the source.
From
Eric Ries (Medium)
by Eric Ries
- Remove any feature or effort that does not add learning.
- An MVP is about validated learning, not a finished-looking product.
- Early adopters expect a rough experience, so start with them.
