Calltek, Inc. is a US-based omnichannel contact center providing white-labeled customer care, technical support, and field services to clients across North America. The company operates with a team of 600 agents across delivery locations in the United States and the Philippines, supporting businesses in telecom, technology, and service-heavy sectors.

Allied Global, founded in 2005 and headquartered in Guatemala, is a leading multilingual contact center and business process outsourcing firm. With a global workforce of over 6,500 employees and 13 delivery centers across 6 countries, Allied serves clients across industries with tailored CX and tech-enabled support services.

Calltek appointed Novistra Capital as exclusive financial advisor to identify a strategic partner that could support its next phase of growth while maintaining operational integrity and service excellence. Novistra led a discreet, founder-sensitive process, leveraging its deep domain knowledge in the CX and contact center sector.

The goal was to find a long-term partner aligned with Calltek’s customer-centric culture, white-label delivery model, and international service ambitions. Novistra guided the transaction through all phases—valuation alignment, structuring, and diligence—ensuring a smooth outcome.

Calltek received a majority investment from Allied Global, creating a compelling partnership that combines Calltek’s white-labelled service expertise with Allied’s global scale and multilingual delivery platform. The investment supports expansion across new verticals, enhances delivery capabilities, and positions both firms for continued growth in a rapidly evolving CX market.

This transaction strengthens Novistra’s track record in mid-market cross-border BPO and CX transactions, particularly in the Americas and Southeast Asia.
