"Before Lupa Hire, we struggled to find a vendor who could match both the volume and the quality we needed to build out our senior development team in Mexico. Lupa gave us real visibility into the pipeline and consistently sent us candidates who actually fit, not just resumes, but people who understood product engineering. It's made a real difference in how fast we've been able to grow the team."
“With Lupa Hire, we rebuilt our entire tech team in less than a month. We’re spending half as much on talent. Ten out of ten”
"We hired 2 of our key initial developers with Lupa Hire. The consultation was very helpful, the candidates were great and the process has been super fluid. We're already planning to do our next batch of hiring with Lupa. 5 stars."
“We’ve worked with Lupa Hire on multiple roles, and they’ve delivered time and again. From sourcing an incredible Senior FullStack Developer to supporting our broader hiring needs, their team has been proactive, kind, and incredibly easy to work with. It really feels like we’ve gained a trusted partner in hiring.”
"Lupa Hire goes beyond typical headhunters. They helped me craft the role, refine the interview process, and even navigate international payroll. I felt truly supported—and I’m thrilled with the person I hired. What stood out most was their responsiveness and the thoughtful, consultative approach they brought."
"What Growth99 loves about working with Lupa Hire is how well they understand our needs. They don't just fill one role; they help us build out a whole team that fits together."
“The quality of candidates is great. Your pricing is reasonable. People are great to work with. I can't imagine a better experience.”

Book a Consultation Call
I help companies hire exceptional talent in Latin America. My journey took me from growing up in a small town in Ohio to building teams at Capital One, Meta, and eventually Rappi, for which I moved from Silicon Valley to Colombia and had to recruit a local tech team from scratch. That’s where I realized traditional recruiting was broken, and how much available potential there was in Latin American talent. Almost ten years later, I still work closely with Latin American professionals, both for my company and for clients. They know US business culture, speak great English, work in the same time zones, and bring strong skills and dedication at a better cost. We have helped companies like Rappi, Globant, Capital One, Google, and IBM build their teams with top talent from the region.
