Proofed Acquires EditorNinja

Strengthening Its Position as the World’s Leading Editorial Desk for Business

Proofed, the largest editorial services provider for content teams, today announced the acquisition of EditorNinja, a subscription-based editing service for content marketers and agencies. The acquisition aligns with Proofed’s focus on scaling support for content teams and expanding its capabilities as the leading editorial partner (providing a human-in-the-loop) for both human-generated and AI-generated content.

“At Proofed, we’re obsessed with one thing: helping business teams publish their best content at scale,” said Adam Harvey, CEO of Proofed. “Absorbing the EditorNinja brand means customers will continue receiving the dependable service they’re used to—now paired with Proofed’s deeper human editorial bench, market-leading AI editing tools, and the strategic support that defines us as the world’s leading editorial desk for business.”

Under the agreement, existing EditorNinja clients will gain:

  • A larger, specialist editorial team with expertise across more industries and formats
  • Enhanced editorial workflows and platform features, including upcoming AI-assisted capabilities
  • A human-in-the-loop model built for modern content teams, supporting both AI-generated and human-written content
  • Stronger account-level support, including dedicated account management

The client transition is expected to be completed by Q1 2026, with a phased approach designed to ensure continuity, consistency, and a smooth onboarding experience.

“I’m thrilled about Proofed’s acquisition of EditorNinja,” said John Doherty, Founder of EditorNinja. “I’ve looked up to Proofed for years, and I’m incredibly confident that EditorNinja customers will thrive with the expanded capabilities, team, and support that Proofed can provide.”

For Proofed, the acquisition represents a natural extension of its mission and long-term strategy. Both brands serve content-driven businesses, but with different operating models and customer profiles. Together, they strengthen Proofed’s ability to partner with content teams of all sizes, from lean marketing functions to global enterprises.
