Solid job data provider with stable APIs and super responsive support **Rating:** 4.5/5.0 stars **Reviewed by:** Sindhu N. | Product Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** February 19, 2026 **What do you like best about TheirStack?** TheirStack has been great to work with, mainly because their communication is really strong. I can text Christian and Xoel on Slack anytime, and they’re always super responsive whether it’s an issue we run into or a new use case we want to talk through. Their APIs have also been very stable. We’ve been using them for over a year and haven’t had any major issues. Any minor issues we did have were handled well, Christian and Xoel always communicated clearly, gave us a resolution date, kept us updated, and provided solutions quickly. Also, they’ve always been flexible and generous with discounts, which we really appreciate. **What do you dislike about TheirStack?** The only thing I’d say is I wish the product was a bit more customized to our use case. Right now, it feels more like a generic API offering, and we’d definitely like to see more data that’s tailored to our specific needs. **What problems is TheirStack solving and how is that benefiting you?** TheirStack is solving the problem of getting reliable job data from the web on a daily basis. We need fresh jobs updated regularly across specific industries for our users, and TheirStack is consistently delivering that for us. ### 2.
