How does Blues make money?

Blues's business model is based on enterprise or commercial offerings; public pricing is included only where disclosed.

Blues makes money from Notecard hardware, connectivity, Notehub usage, enterprise plans, and support. Its pricing page says Notehub does not charge a monthly subscription fee for the base usage model and charges based on Events flowing into Notehub, while newer Notehub tiers and enterprise features are sales-led.

Growth is driven by physical product companies turning hardware into connected services without building a cellular stack from scratch. Buyers include embedded engineering, product, cloud, operations, and finance teams.
