“An award-winning data software company that develops next-generation product data management tools“

Makersite is an award-winning data software company that develops next-generation product data management tools for the global manufacturing industry.  The platform is the only cloud-based platform combining data aggregation and live applications for agile product life cycle management.

Makersite empowers companies to manage product sustainability, cost, and compliance. The state-of-the-art approach to product data management has allowed companies of all shapes and sizes to take advantage of what it has to offer. For larger enterprises, the reduction in complexity and increase in agility is the main aim, while for small businesses, the search for cost effective solutions is the main driving force. Through a cutting-edge technology, big data, and breakthrough algorithms, companies can track a product’s emission footprint throughout the entire supply chain, including Scope 3 emissions, bringing carbon accounting to the next level.

Makersite uses artificial intelligence and graph technology to build digital twins of manufactured products. This approach enable teams to measure impacts and collaboratively identify optimal mitigation strategies and new sourcing opportunities in real-time and make better products, faster. Engineers and product teams can develop more compliant, safer, cost-effective, and environmentally friendly products faster, and get results up to 50x faster than traditional methods.
