This year’s research revealed several key MSP market trends, including:

  • Honorees generated a combined $1.4 billion in vertical market annual recurring revenue in 2020, up from $1.12 billion in 2019. The surge involved organic growth combined with continued merger and acquisition (M&A) activity.
