Incumbently vs TheirStack Job posts are half the story.
What each tool sees, how early it spots a switch, and what it costs. Facts about TheirStack come from its own site and docs.
TheirStack reads job posts, and it does that well. But a job post says what a company wants, not what it runs. Incumbently confirms the tool in infrastructure, catches when an old tool is removed, and adds buyer contacts. TheirStack's docs say it does not infer when a company stops using a tool.
- Confirms tools in DNS records, subdomains and certificate logs, not just job text
- Logs removal and switch events with dates
- Includes buyer contacts, with no hand-off to another tool

A company switching tools leaves signals in a rough order. Here is which steps each tool can see, based on the sources it uses.
What a switch alert looks like. With what changed and when.

- Oct 11help-new subdomain appears in certificate logsCert
- Oct 19New Head of Support, used Databricks at last jobHire

- Watch Snowflake and see every customer it has
- Get an alert the week one of them starts switching
- Open the case file to see each signal and where it came from
- Draft the first email straight from the alert
An honest split.
- You need to know what a company runs today, not only what it is hiring for
- You want alerts when a competitor's customer starts leaving
- You want contacts in the same workflow
TheirStack fits if you want the cheapest raw job-post data or a large job-search API.
Incumbently vs TheirStack, answered.
Its docs say it does not infer absence, so it won't tell you when a company stops using a tool. Incumbently logs a removal when the tool's infrastructure goes away.
Yes. It has a free plan and an API from $49 a month (checked November 2026). Incumbently costs more because it adds infrastructure proof, switch alerts and contacts on top of job data.
Yes. Job posts are one of 75+ signals. We pair them with infrastructure records so a hiring hint becomes a confirmed change.
