International Synergies Limited

What International Synergies Limited does

International Synergies Limited is a UK-based private company (registered in England and Wales, company number 05586343), founded in 2005, that operates as a specialist consultancy and software provider in industrial symbiosis — the practice of cross-organisational resource reuse. The company employs fewer than 20 staff across offices in Birmingham (headquarters) and Belfast, Northern Ireland, and positions itself as the world's leading expert in the field, claiming 42 million tonnes of CO2e savings facilitated in England alone, with operations spanning 30 countries and 6 continents.

The company's core technology is the SYNERGie® platform, originally launched in 2009, which hosts data on 100k+ resources from 30k+ organisations and includes the ADVISOR reference library of successful reuse solutions. SYNERGie Direct, a mainstream version of the platform, was launched in 2025 for the UK and Republic of Ireland. Revenues are generated through three streams: platform licensing/subscription (SYNERGie Direct), professional services (industrial symbiosis facilitation, net zero strategy consulting, place-based decarbonisation, capacity building), and managed project delivery under public-sector contracts (e.g., West Midlands Resource Reuse Network for WMCA, Resource Matching Service for Northern Ireland for Invest NI). Free resource matching services to SMEs in funded regions produce no direct revenue but expand the platform's data footprint.

Go-to-market is hybrid, combining enterprise field sales, government-funded regional service delivery, event-driven workshops, and European research collaborations such as the Horizon Europe RISERS project (commenced January 2024). The customer base is broadly split between private-sector businesses (manufacturing, water utilities, construction, food and drink) and public-sector/regional bodies. No venture funding rounds, parent company, or revenue figures are disclosed, and the company appears to be founder/management-owned. Notable named customers and partners include United Utilities, West Midlands Combined Authority, Invest NI, Hull City Council, HEY LEP, Balfour Beatty Vinci (HS2), University of Leeds Yorkshire Circular Lab, and the European Committee for Standardisation.
