Zelo

In 2017, ZeLo was founded by two lawyers who felt that traditional legal models were ripe for disruption. After working at one of Japan's largest law firms, the founders developed a firm belief that the inefficient "hourly billing model" would be fundamentally challenged by the advent of new technologies. To remain competitive, law firms would have to eliminate repetitive tasks through the use of AI, thus allowing fewer, more highly-skilled lawyers to better serve their clients. To this end, the founders have leveraged artificial intelligence (through the LegalForce Platform) to automatically and instantly perform repetitive tasks-allowing its lawyers to focus on high-value services. The "proof" that their vision has succeeded is borne out by the rapid growth of the firm - which now includes nearly 30 lawyers and paralegals and more than 100 retainers.
