Raiku

Raiku offers Blackline, a service that runs customers' trading strategies on the same hardware as Raiku's custom Solana validator, which builds the blocks. The website states that trades in Raiku-produced blocks are captured 3.5 times sooner than in other validators' blocks, and says Raiku does not set prices or guarantee outcomes.

Blackline is built for a small number of trading firms and asset managers active on Solana. The input does not describe pricing or the revenue model. The website also lists advisers and announced validator relationships with Kiln, Everstake, Staking Facilities, Blockdaemon, Chorus One and H2O Nodes.

Raiku was founded in 2024 by Robin A. Nordnes, who is Founder and CEO. The company has raised $13.5M; Pantera Capital led the seed round, and Figment Capital and Big Brain Holdings co-led the pre-seed. The company's registered country is the United Kingdom, and the website lists two open application roles, Engineering and Marketing & Growth, both remote.
