Alto Merges into Revelo as Demand for AI Devs Accelerates

U.S.-based hiring platform Revelo has acquired Alto amid surging demand for professionals skilled in training large language models.

Launched in 2015, Alto transitioned from a remote-first staffing company into a comprehensive tech talent platform.

“The merger helps us to scale our mission,” said Juan Salas, co-founder and CTO at Alto.

“We built Alto on the belief that Latin America could be a driving force in the AI revolution. I’m proud of what we created, and excited to see that vision continue through Revelo,” Salas said, confirming that both he and his co-founder, Pablo Baldomá Jones, would gain a role in Revelo.

“Together, we’re building an end-to-end solution that removes the friction from hiring in Latin America,” Baldomá Jones said.

When asked how many Latin American professionals they had placed with U.S. companies, Baldomá estimated “the figure could be somewhere between 800 and 1,000.” Alto’s client list includes 24 Hour Fitness, Anytime Fitness, and BBVA.

During the interview, both co-founders acknowledged the sharp increase in demand for AI talent.

“The demand for AI-literate developers — especially those who can contribute to complex post-training work on large language models — is accelerating.”

The acquisition significantly expands Revelo’s presence in the region and marks its fifth deal in just 30 months, underscoring its rapid growth strategy. Revelo stated that, following the acquisition, the total number of professionals on its platform has reached 400,000.

According to Revelo, companies are competing to secure talent capable of enhancing large language models for advanced tasks such as coding.

Hiring related to large language model training accounted for 22% of Revelo’s revenue in 2024, according to Spanish news outlets, and analysts believe this share is likely to increase.

This growth is driven by companies developing their own AI models and seeking specialized engineers and datasets to train them. They require human input to interact with machines and validate the generated code.

“It is simply impossible to hire developers at scale without the help of platforms like Alto,” Salas said, with Baldomá Jones adding that hiring Latin American talent involves extensive backend processes such as identifying and vetting candidates.

Salas dismissed the notion that automation in software development would diminish the demand for IT talent. Instead, he emphasized that companies are actually scaling up their operations and increasing their need for skilled professionals.
