Nobl9 has secured $21 million in Series B funding round, led by Series A investors Battery Ventures and CRV.

Series A investors Bonfire Ventures and Resolute Ventures also participated, along with new investors Harmony Partners and Sorenson Capital. Proceeds from the Series B will fund programs focused on customer deployment success, software engineering team expansion and marketing programs.

Along with the funding round, the company announced the general availability of its Nobl9 Service Level Objective (SLO) Platform.

According to the company, the Nobl9 SLO platform is the first SLO-centric operations platform purpose-built to drive widespread adoption of SLOs.

Users can easily balance infrastructure reliability with the rapid release of software enhancements, while optimizing productivity and controlling infrastructure costs. The launch comes after a beta program that began last year.

The company already has more than 50 organizations on the platform from diverse market verticals including financial services, communications, ecommerce and media. Users include Adobe and Brex.

Marcin Kurc, co-founder and CEO of Nobl9, said: “End-users want reliable software that meets their expectations for availability and performance. CEOs realize software reliability is central to business performance and profitability. Our platform is exactly what those enterprises need to build the feedback loops that are critical to sustainably running reliable, modern software.”
