What OnGres does

OnGres (legal entity: ONGRES S.L., headquartered in Alcobendas, Madrid, Spain) is a private, founder-led company that specializes exclusively in PostgreSQL database infrastructure, consulting, professional services, and R&D. Founded by Álvaro Hernández and co-founded by César Calvo, the firm operates across five cities in four countries — Spain, the United States, Argentina, Chile, and Brazil — and serves enterprise customers including the European Central Bank. The company positions itself as the only firm focused exclusively on Postgres that combines open source products with enterprise-grade professional services, and operates as a Kubernetes Certified Service Provider (KCSP) under the CNCF.

Its core technology portfolio centers on two open source products: StackGres, a cloud-native Postgres platform for Kubernetes that supports roughly 200 extensions with dynamic filesystem loading and unloading and is distributed via a self-serve YAML or web UI flow; and PostgresqlCO.NF, a free configuration management tool with a REST API, multilingual documentation (English, French, Japanese, Chinese, Russian), and broad community adoption. The team comprises Postgres DBA experts (many of whom speak at global Postgres conferences), DevOps engineers, and Java developers with deep Postgres expertise, including contributors to the official Postgres JDBC driver. R&D has been partially funded by a €586,703 CDTI grant (2023) targeting PostgreSQL-on-Kubernetes optimization including autoscaling, sharding, and task automation.

The business model combines community-led open source distribution (the StackGres extension repository serves 1.5 million extensions per month totaling 1TB of data) with enterprise-grade professional services. Revenue streams include Support with SLA up to 24x7, Data_DevOps managed services, Consulting, Training, Migrations (specializing in Oracle-to-Postgres with near-zero downtime), Health-Check assessments (starting at $3,500), and Kubernetes implementation services. Distribution combines self-serve open source downloads, direct enterprise sales, and cloud marketplace partnerships with Google Cloud, Microsoft Azure, Nutanix, and Pythian.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• Timescale: Timescale builds a Postgres extension and managed cloud service for time-series and analytics workloads. It overlaps with OnGres in the Postgres extension ecosystem (Timescale is one of StackGres' most downloaded extensions) and offers a competing managed Postgres service.
• YugabyteDB: YugabyteDB is an open source distributed SQL database with a PostgreSQL-compatible API. It targets the same cloud-native, distributed SQL workloads as StackGres and represents an alternative path to scalable Postgres-compatible deployments.

Broad incumbents

• Azure Database for PostgreSQL: Microsoft Azure's managed PostgreSQL service (Flexible Server, Hyperscale) is a broad incumbent alternative to OnGres' StackGres and managed services. The partnership with Azure creates a co-sell channel but also positions Azure as a competitive offering.
• Citus (Microsoft): Citus provides distributed PostgreSQL, now part of Microsoft and shipped as Hyperscale (Citus) on Azure Database for PostgreSQL. It competes with StackGres in enabling scalable, distributed Postgres deployments and is a direct alternative for enterprise customers evaluating Postgres-on-cloud solutions.
• Google Cloud SQL for PostgreSQL / AlloyDB: Google Cloud's managed PostgreSQL offerings, including AlloyDB, compete with OnGres for cloud-native Postgres deployments. As a formal OnGres partner, Google is also a channel but its native services set the price floor for managed Postgres.
• AWS RDS for PostgreSQL / Aurora: AWS offers fully managed PostgreSQL via RDS and Aurora with built-in HA, backups, and 24x7 support. It is the default incumbent competing with OnGres' managed Postgres services and StackGres for enterprise workloads.

Direct peers

• EnterpriseDB (EDB): EDB is the largest pure-play Postgres company, offering EDB Postgres distributions, enterprise support, migrations, and training. It competes head-to-head with OnGres' StackGres and professional services across nearly the same Postgres-specialist buyer.
• Crunchy Data (Crunchy Bridge): Crunchy Data is a Postgres-focused company offering enterprise Postgres distribution, Crunchy Bridge managed Postgres, and 24x7 support. It overlaps with OnGres on cloud-native Postgres, managed services, and enterprise support contracts.
• Percona: Percona provides open source database services and software for PostgreSQL (and MySQL/MongoDB), including managed services, consulting, and training. Its Postgres support and migration services directly overlap with OnGres' Support, Data_DevOps, and Migrations offerings.
• Pythian: Pythian is a data and analytics services firm with a strong Postgres practice, offering consulting, managed services, and migrations. As a formal OnGres partner, it is both a peer in Postgres services and a collaborator on joint customer engagements.
