What happened

Hightekers, a workforce services group founded in London and Paris in 2016, closed its purchase of Serviap Global on 25 November 2025. On 28 April 2026, the group announced that the EOR businesses of Hightekers, Eos Global Expansion and Serviap now operate as one company under the Rivermate name. The Serviap and Eos names were to be dropped and their staff, clients and day-to-day operations carried over, while Hightekers kept its own name for freelancer management. Serviap co-founder Victor Anaya now runs Latin America for Rivermate.

Former Serviap clients can put these questions to their Rivermate contact, and our guide to EOR contract clauses lists the terms to check.

Has your service agreement been assigned to a Rivermate entity, and what do its change-of-control and assignment clauses let you do?
Will your current fees hold until renewal, and will renewal keep your Serviap terms or move you to Rivermate’s published rates?
When will your account move to the group’s single platform, and when will you receive an updated privacy notice if worker data moves to a new controller or system?

The infrastructure page does not say which of the 11 have a group-owned legal entity, and none of the deal announcements said where Serviap employed workers through its own entities. The entity named on each worker’s employment contract and payslip is the legal employer, so ask Rivermate whether that entity belongs to the group or to a partner. Our guide to owned entities versus partner networks explains what that split means for buyers.

Keeping Anaya in charge of Latin America suggests continuity for former Serviap clients. Check that the same in-country payroll and HR specialists still handle your workers, and if they do not, compare options in our Brazil EOR guide and Colombia EOR guide.

Mexico clients should check whether Rivermate is registered with REPSE

In Mexico, Serviap’s home market, the 2021 subcontracting reform bears directly on EOR. Published in the Official Gazette (DOF) on 23 April 2021, it amended the Federal Labor Law. Article 12 now bans the subcontracting of personnel, while Article 13 allows specialized services or works if the provider is listed in a public registry kept by the labor ministry (STPS), known as REPSE. Under Article 15, registration must be renewed every three years.

Law firms Ogletree Deakins and Garrigues note that the services must fall outside the client’s corporate purpose and main activity. They add that a client can be held jointly liable for a non-compliant provider’s labor and social security obligations, and that payments for non-compliant subcontracting cannot be deducted or credited for tax.

An EOR employs people who work for another company, which in our view sits close to the personnel subcontracting that Article 12 bans. Rivermate’s Mexico EOR guide, last updated on 12 October 2026, raises REPSE only for employees who work on-site at the client and says those cases need extra review. It gives no registration number.
