Best Mercor alternatives in 2026

Quantiphi has worked only on AI, machine learning and data since it started in 2013, and it now employs somewhere between 3,000 and 4,000+ people, depending on which directory you trust. That makes it the biggest company on this page by a wide margin. Its staff augmentation product, Elastic Staffing, was built with AWS for teams that need generative AI or ML specialists faster than a normal hiring cycle allows. In one company case study, a U.S. energy supplier brought in eight specialists through the program and reported savings of more than $570K (per company website; independently unverifiable). The firm is headquartered in Marlborough, Massachusetts, and Google Cloud named it 2025 AI Partner of the Year for North America.

How it differs from Mercor: A multi-thousand-person AI and data bench with a named staffing program run with AWS. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Quantiphi is better for enterprises that need several AI specialists at once from a single AI-only supplier.

Tensorway was set up in Alicante, Spain in 2019 to do one thing: AI engineering. Its delivery practice draws on more than two decades of software engineering. Its staff-augmentation service supplies ML engineers, AI agent developers, data engineers and other specialists who work inside the client's own Slack, Jira and repositories. Most engagements start as a squad of two to five people and change shape as the work moves from research to production, with a part-time fractional expert as an option when a full seat is too much. The company's case studies include a multi-billion-euro Swedish private equity fund, where an AI-agent system reportedly cut deal-sourcing time by 80% and screens more than 5,000 opportunities in hours (per company website; independently unverifiable).

How it differs from Mercor: Senior AI engineers run the screening, and knowledge transfer to in-house staff is part of every engagement. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Tensorway is better for product teams that want senior AI engineers inside their own workflow and want the know-how to stay.

deepsense.ai started in Warsaw in 2014 and has spent its whole history on machine learning, which shows in the depth of its MLOps and computer-vision work.

While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Sigmoid is better for CPG and retail data teams that need ML and data engineers billed monthly.

Data Science UA began in Kyiv in 2016 as an effort to bring the country's AI talent together, starting with the first data science conference there. The community still matters: the company cites a network of more than 30,000 AI engineers, and that network is the source for its recruiting and staff-augmentation business. Clients can hire people outright or have Data Science UA employ and manage a team in Ukraine, which one Clutch reviewer valued because it removed office and people management entirely. Its legal headquarters is listed in London.

How it differs from Mercor: Recruiting from Ukraine's largest AI community, with managed teams as an option. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Data Science UA is better for companies building a Ukrainian AI team they will eventually own.

It also builds FLIP, a low-code DataOps platform, which tells you its people know data integration well.

How it differs from Mercor: Three delivery models under one contract, from Austin, Argentina and India. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Kanerika is better for enterprises modernizing data platforms that want onshore, nearshore and offshore staff from one firm.

Vstorm has built AI systems since 2017 and now concentrates on LLM agents, with about 25 AI engineers on its bench and 40+ staff in total, mostly in Wrocław and remote across Poland. Its website names three situations it fixes, and one is an existing team that has stalled; there, Vstorm adds senior engineers who specialize in agent design, reliability and integration. Its longest package embeds a manager, a tech lead and engineers for three months or more. Deloitte and EY have both recognized the company, according to directory listings.

How it differs from Mercor: Senior agent engineers who join an existing team to fix reliability and integration. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Vstorm is better for teams whose agent prototype works in a demo but fails in production.

The company says it doubled revenue in its most recent year and runs a fellowship to train new MLOps engineers.

How it differs from Mercor: Open-source MLOps specialists with security-cleared engineers for government work. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Fuzzy Labs is better for UK data science teams, including public sector, that need MLOps engineers working alongside them.

Jaclyn Rice Nelson and Noah Gale started Tribe AI in 2019 to help companies hire contract AI talent, and TechCrunch reports it ran bootstrapped for six years before raising venture money in 2024. The business has since grown into a full AI services firm, but its talent model still rests on a network: Tribe says more than 600 AI engineers and product leaders work with it as per-project consultants. Engineers now work as forward-deployed teams inside the client organization, against its real systems. Built In lists about 35 employees, which fits a firm whose bench is mostly contractors.

How it differs from Mercor: A curated network of senior AI practitioners deployed inside the client's organization. While Mercor excels at AI interviewing that can screen very large candidate pools quickly, Tribe AI is better for companies that want senior AI engineers and product leaders for a defined initiative.

Addepto has worked on AI and data in Warsaw since 2017, with a strong client base in industrial and automotive companies. KMS Technology, an Atlanta engineering firm backed by Sunstone Partners, acquired it in December 2025.
