Built by two people who've sat on both sides of the table.
Hopper is a tool for rehearsing the interviews, negotiations, and high-stakes career conversations you can't afford to fumble. Practicing alone in front of a mirror doesn't work. Paying for coaching you can only do once or twice doesn't scale. You need reps, and you need them on demand.
Why we built this
Between us, we've interviewed and been interviewed hundreds of times. We've watched qualified people lose roles they should have won, almost always on the moments that happen inside the conversation rather than on the resume.
The variance usually isn't about knowledge. It's about reps. Pilots don't fly a 737 their first day on the job. They spend hundreds of hours in a simulator first. The conversations that decide your career deserve the same treatment.
Hopper is that simulator. Run the moment that matters as many times as you need to, until you stop being surprised by it.
Who we are
Enrique Rubio is the founder of Hacking HR, a global learning community for HR professionals. He's spent his career on the hiring side of the table, designing interview processes, coaching managers, and watching what separates the candidates who land roles from the ones who don't.
Ernesto Humpierres is a technical founder and product builder. He's been the candidate, the hiring manager, and the one rewriting the job description at 2 a.m. He builds Hopper because the tool he wanted didn't exist.
What Hopper is
Hopper is an AI-powered rehearsal environment for interviews and high-stakes career conversations. You bring a job description or describe the moment you need to practice. Hopper builds the scenario, plays the interviewer or counterparty in real-time voice, and gives you a structured report afterward covering what landed, what didn't, and where to focus next time.
Hopper is not a job board. It's not a recruiter, a resume builder, or a substitute for a coach who knows you personally. It's a place to get the reps that make all of those other things work better.
How we think about your data
The conversations you rehearse on Hopper are some of the most personal information you'll ever give a piece of software. Your weaknesses, your salary expectations, your fears about whether you can land a particular role. We treat them that way.
We don't sell your data, and we don't use your interview content to train third-party foundation models. Every service that touches your information is listed in our privacy policy at /privacy.
