Market consolidation in the TEM space is taking place and will accelerate. Why? Here are some reasons:

• Completeness of Product/Service
  The market is moving beyond being a national market to a global market, away from billing validation to full telecom lifecycle, from fixed to mobile…..
• Flawed Business Model
  Most vendors have their resources onshore and deploy a premise based model with high levels customization (no SaaS). Their ability to scale is limited and they face high CapEx and OpEx to maintain their service. 
• Limited Differentiation & Competitiveness
  Most US TEM players have limited differentiation and find themselves in a very competitive market place leading to high customer churn and high customer acquisition cost.
• Retreat of Venture Capital and Private Equity

Given the above considerations this implies a lot of the TEM vendor will simply not reach profitability leading to a shake out and companies looking for economies of scale.
