TriggerMesh, a startup building on top of the open-source Kubernetes software to help enterprises go “serverless” across apps running in the cloud and traditional data centers, has raised $3 million in seed funding.

The round is led by Index Ventures and Crane Venture Partners. TriggerMesh says the investment will be used to scale the company and grow its development team in order to offer what it bills as the industry’s first “cloud native integration platform for the serverless era.”

Founded by two prominent names in the open-source community — Sebastien Goasguen (CEO) and Mark Hinkle (CMO), based in Geneva and North Carolina, respectively — TriggerMesh’s platform will enable organizations to build enterprise-grade applications that span multiple cloud and data center environments, therefore helping to address what the startup says is a growing pain point as serverless architectures become more prevalent.

TriggerMesh’s platform and serverless cloud bus is said to facilitate “application flow orchestration” to consume events from any data center application or cloud event source and trigger serverless functions.

“As cloud-native applications use a greater number of serverless offerings in the cloud, TriggerMesh provides a declarative API and a set of tools to define event flows and functions that compose modern applications,” explains the company.

One feature TriggerMesh is specifically talking up and very relevant to legacy enterprises is its integration functionality with on-premise software. Via its wares, it says it is easy to connect SaaS, serverless cloud offerings and on-premises applications to provide scalable cloud-native applications at a low cost and quickly.

“There are huge numbers of disconnected applications that are unable to fully benefit from cloud computing and increased network connectivity,” noted Scott Sage, co-founder and partner at Crane Venture Partners, in a statement. “Most companies have some combination of cloud and on-premises applications and with more applications around, often from different vendors, the need for integration has never been greater. We see TriggerMesh’s solution as the ideal fit for this need which made them a compelling investment.”
