Ecotek is a technology consultancy and outsourcing firm established in 2018 as an extension of Ecopark Group's smart city planning initiative. Our expertise has enabled us to lead the group's efforts in providing smart city solutions for its 35,000 residents and over 1 million annual visitors across the country. Through our collaborations with international partners, we have developed a robust city operating system that connects data, people, and governance at a new level. In 2021, Ecotek launched Ekko (https://ekko.vn), a financial wellness service designed to enhance the financial lives of employees by transforming the way they receive their pay. Our innovative service empowers employees to access their salaries on demand via our app, thus enabling greater control and financial stability. Our research with existing partners indicates that on-demand salary access is a vital factor in attracting and retaining talent, particularly within the manufacturing and service industries. Ultimately, our goal is to reduce the reliance on predatory lenders and debt traps, which can have significant implications for the overall health of the economy.
