Discover why Spline is different

Underpromise and overdeliver

Quantitative Offerings

Spline's data offerings are created with no human input and optimized frequently, resulting in the most accurate relationships of all possible data. Our data represents the whole market, not just one niche corner.

Provable Results

Spline openly measures and benchmarks its curve performance against actual market movements and trade prices. If we aren’t able to prove that our product is better, we shouldn’t be trying to sell it.

Transparent Philosophy

Customers have a direct view into the data constructing Spline’s curves and bond pricing, and the performance of our products. The cost of our products and the processes for testing them are also no secret.

Inventive and Creative

Spline’s products represent new ideas or substantial improvements over legacy resources in the municipal market. Our goal is to better our customers' ability to compete and improve the investing experience

Automation

Spline allows you to automate your processes with the help of our API. The API is included with the business or greater plans.
