Salary benchmarks
Our take
So far, the increasing institutional interest in the value of crypto-assets has been stymied by a lack of scaled, efficient, and secure infrastructure that these institutions could use for trade. Talos addresses the problem of digital asset trading between institutions, helping them to securely sidestep these obstacles into a fresh market with potentially huge returns.
The company provides a range of end-to-end, highly configurable tools to populate and facilitate the institutional crypto-asset market from just one platform. Talos' approach is helping to lower the bar for wide-ranging adoption of cryptocurrency, supporting the full lifespan of digital assets trading. That said, because the company is developing an entirely new asset class market, progress is accelerated, and competition may have a chance to overtake.
Promising for Talos was the interest of prominent investors, including PayPal and Fidelity, during their Series A and B funding rounds. The funds were used to create an institutional-grade service that would help shape and spearhead this developing market. More recently, the company has formed several significant partnerships, including with BlackRock, and acquired D3X Systems, the integration of which will enable its clients to design, validate, implement, and manage highly customised portfolios.
