WatchWire, now operating as “WatchWire by Tango,” is a leading provider in the sustainability, energy, and emissions data management market. The company has evolved rapidly over the past two decades, with major expansion following its 2023 acquisition by Tango, a global leader in real estate and facilities management software.
Founded in 2000 in New York City, WatchWire began as a consultancy but pivoted to platform and product development, bootstrapping its early growth.
The company developed proprietary methods for ingestion and analysis of non-standardized utility and sustainability data, addressing market gaps in ESG and emissions compliance.
From 2021, WatchWire accelerated growth with strategic debt financing, leading to a 40% pipeline increase and double their close rate for deals by investing in product-led growth and new talent.
WatchWire raised a $2.5 million investment facility from TIMIA Capital in 2021, which facilitated its expansion and eventual acquisition.
Financial details of the Tango acquisition remain undisclosed, but the company transitioned from a lean, bootstrapped operation to become part of a 300+ person organisation under Tango and Berkshire Partners’ ownership.
The platform automates the collection of energy, water, waste, and emissions data, providing real-time and interval reporting, project tracking, budgeting, ESG and carbon tracking, and regulatory compliance support.
Features include integrations with ENERGY STAR, LEED, GRESB, and CDP, visual analytics, bill simulations, customizable dashboards, private labeling, audit-grade reporting, and M&V for efficiency projects.
Provides APIs for custom integrations and robust tools for exporting, consolidating, and analyzing sustainability data at scale.
Tango’s acquisition in 2023 was transformative, combining WatchWire’s data expertise with Tango’s workplace management and wider facilities lifecycle offering, broadening the market, especially in the owner/landlord and regulated municipal segments.
The combined company has developed integrations with space management, desk booking, lease administration, and expanded product modules such as visitor management and portfolio strategy.
Since the acquisition, WatchWire has enhanced its automation, self-service analytics, SMB support, and real-time energy monitoring modules.
WatchWire historically operated as an entrepreneurial, PE-backed company with a strong emphasis on agility, innovation, and customer consultation.
The combined company now serves more than 500 organizations in 140+ countries, including global real estate portfolios, Fortune 500 brands, municipal agencies, and education/healthcare sectors.
WatchWire’s community has grown with the acquisition, offering joint webinars, newsletters, user groups, and proactive customer success/support teams to engage and educate users on industry, regulatory, and platform developments.
