Simplify's Take

What believers are saying

  • August 2026 Shadow-Planner Alert expands incident communications beyond core MSP services.
  • July 2026 ColorTokens and BDO partnerships widen cyber-assurance and breach-containment revenue.
  • June 2026 Mitel healthcare recognition and multiple NHS contracts deepen vertical penetration.

What critics are saying

  • December 2025 Worldleaks breach exposed Wavenet’s internal files, damaging trust and renewal rates.
  • January 2025 post-Daisy integration triggered UK job cuts, signaling duplication and culture clashes.
  • Macquarie-backed consolidation leaves Wavenet dependent on flawless cross-sell execution; one stalled integration threatens the rollup thesis.

What makes Wavenet unique

  • January 2026 merger made Wavenet the UK’s largest independent MSP.
  • July 2026 NCSC Assured Service Provider status validates regulated cyber services.
  • September 2026 public-sector wins at NAO, HS2, and NHS prove procurement strength.
