About Client:

Bisonai aims to provide infrastructure services for companies to easily build Web3, the internet of the future, with blockchain technology. Our company was founded by 2 engineers with years of experience in different technology sectors. Bryan (CEO) is a robotics engineer and worked at Kakao Brain for several years, the artificial intelligence technology research and development subsidiary of Kakao. Martin (CTO) has an AI + ML background and worked at Hyper Connect, a global technology company based in Seoul that provides video and AI-powered social discovery products. At Bisonai, they are aiming to innovate in blockchain technology.

The blockchain sector

is abundant with innovation, but not without its risks. Led by the cryptocurrency industry, but it is still immature and regular users still face the reality that their assets could be lost or the blockchain that they’re built upon could fail.

With our years of experience in established IT sectors, Bisonai are excited to bring our experience to the blockchain sector and see the immaturity in the space as an opportunity!

Firstly, we aim to provide blockchain consulting as well as a solution-based SaaS business in the form of B2B in order to understand the needs of the market and build a mature technology base.

we are a CIC (Company in Company) of the organization Krust Universe.

Krust operates on the Klaytn blockchain mainnet and has an excellent in-house development team in Korea.

We have a clear goal to spin-off when we establish a clear business model and attain cash flow. Many startups have a lack of resources to keep up with the pace of technological advancement. However, with the support of Krust and leeway to work with fantastic partners on exciting projects, we see great opportunities ahead with Krust’s wholehearted support to focus on the essence.
