Vektor’s premise is that Decentralized Finance should be more accessible to those who want to participate yet lack the technical skills to do so.

We are building a product to help these investors and institutions discover, assess, and execute transactions and trading strategies on DeFi, without having to navigate the complexities. All the data aggregation, transaction construction, smart contract handling, and execution overhead is handled by the product, while still non-custodial, leaving the investment professional to do what they do best.

We’re a fully-remote, VC-backed startup that was selected by Y Combinator for their summer ‘21 batch.

Join us and help us build the tool that brings the next trillion dollars to DeFi.
