Why a software agency built its own hiring platform
WizzHire started as an internal tool for our own recruitment. Running our own product changed how we build for clients. Here's what it taught us.
Agencies love to say they build products. We wanted to be able to prove it, so we built one, with our own money and our own name on it.
WizzHire started the way most honest products do: as a fix for our own pain. Our hiring was sprawled across job boards, inboxes, and spreadsheets, and every open role meant hours of manual CV reading. We built an internal tool that pulled the whole workflow into one place: posting roles, managing applications, and collaborating on candidates. On top of that we added AI screening that reads and ranks applicants against each role.
Two years of using it in our own hiring later, it had become good enough to release. Today WizzHire is a product in production, and the full story is in the case study.
What it changed for us
The numbers first. In our own hiring, AI screening cut the time we spend per role by around 80%. Roles that used to take weeks of manual review now produce a shortlist in days. Those are our numbers from our own use, and we're careful to say so, because customer-side numbers should come from customers.
Dogfooding is a forcing function. When you run the product you built, every rough edge lands on your own desk. There's no handover, no "the client didn't mention that". If the screening ranks a strong candidate poorly, we feel it in our next hire. Even the "book a call" button on this website runs on WizzHire's scheduling.
It made our client promises concrete. When we tell a client we can take a product from idea to launch and keep shipping after, WizzHire is what we point at. Same team, same process, same care about data handling: candidate data is sensitive, so privacy and EU data hosting were part of the design from the first commit, not an afterthought.
Why this matters if you're hiring an agency
There's a difference between a team that has delivered projects and a team that has operated a product: uptime, support, data protection, the unglamorous iteration after launch. Running WizzHire keeps us honest about what shipping really costs, and that honesty flows back into how we scope and build client work.
If you're curious what that looks like applied to your product, tell us what you're building, or see how we work.
