Case Study
Operator-to-operator teardowns of vertical SaaS category leaders. What worked, what almost killed them, and what you should steal.
What This Covers
Every Guild case study is an operator-to-operator teardown of a vertical SaaS company: the market context, the founding insight, the wedge, the scaling plays, the near-death moment, and what the AI-native era changes about the model.
Why GTM Is Different Here
These are written for people who have to make a decision this quarter, so the emphasis is on the mechanics rather than the narrative. Each study names the archetype the company ran, cites the revenue and adoption figures against public sources, and closes with the plays that transfer to a different vertical. Reading two studies from the same archetype is usually more useful than reading five from the same industry, because the archetype is what determines your hiring plan, your pricing model, and your channel mix.
What To Read First
Pick the archetype that matches your motion on the archetypes page, read the two studies listed under it, then read one study from a different vertical running the same archetype to separate the industry detail from the transferable play.
