Simplify's Take

What believers are saying

  • Holycode says it served 200-plus startups by August 2026, signaling repeatable demand.
  • Miami expansion under Terry Fehlmann targets low-code, SaaS, AI, and university spin-offs.
  • Full-service portfolio spans nearshoring, product development, ERP, and low-code, increasing wallet share.

What critics are saying

  • US expansion from Miami faces entrenched rivals like Thoughtworks, EPAM, and Globant.
  • Holycode depends on founder-led execution; Terry Fehlmann's US push concentrates go-to-market risk.
  • A prolonged startup funding drought would shrink Holycode's client base and erode utilization.

What makes Holycode unique

  • Since 2014, Holycode serves startups from MVPs to IPO with nearshoring, ERP, and low-code.
  • EtonDigital merged into Holycode Products in April 2025, deepening product-development talent.
  • Holycode Labs launched in Miami in 2024, targeting DACH, UK, and US clients.
