What is it
What Is the PostgreSQL Customers List?
The PostgreSQL customers list is a verified, regularly refreshed database of companies (typically 50-200,000+ employees) running PostgreSQL in production across managed services (Amazon RDS for PostgreSQL, Aurora PostgreSQL, Google Cloud SQL, AlloyDB, Azure Database for PostgreSQL Flexible Server, Neon, Supabase, Crunchy Bridge, Heroku Postgres, EDB Postgres) and self-hosted deployments, with named VP Engineering, CTO, Director of Database Engineering, Director of Platform Engineering, Director of Backend Engineering, and developer-led decision-makers at each account. Every record on the BizzContacts PostgreSQL list is tagged with the specific PostgreSQL deployment model and managed service, PostgreSQL version where derivable, PostgreSQL extensions in use (pgvector for AI/RAG, TimescaleDB, Citus, PostGIS, PostgREST), AI/RAG application status (pgvector customers building RAG), underlying cloud provider, ORM choice where derivable, and PostgreSQL ecosystem partner integrations.
The list feeds outbound prospecting for modern Postgres-anchored services (Neon for serverless Postgres displacement of RDS, Supabase for developer-led Postgres + auth + storage, Crunchy Bridge for managed Postgres expertise), PostgreSQL performance optimization (Datadog Database Monitoring, pganalyze, EDB Postgres performance tools, Percona Monitoring and Management), Postgres backup and replication (pgBackRest, WAL-G, Barman commercial support), Postgres extension commercial support (TimescaleDB, Citus enterprise, pgvector services), AI vector databases competing with pgvector (Pinecone, Weaviate, Qdrant, Chroma), Postgres migration services (Oracle-to-Postgres, SQL Server-to-Postgres, MySQL-to-Postgres for cost and feature reasons), modern ORMs for Postgres (Prisma, Drizzle ORM, SQLAlchemy, ActiveRecord, Diesel), modern application platforms paired with Postgres (Vercel, Render, Railway, Fly.io), database observability (Bytebase, Liquibase, Flyway for schema migrations), and competing OLTP databases targeting PostgreSQL evaluation. Records ship with company firmographics, named decision-makers, and audit-trail metadata.
02Definition
Why a PostgreSQL Customer List Matters in 2026
The pgvector AI/RAG application boom (pgvector adoption exploded in 2024-2025 as enterprises evaluated AI vector databases), the serverless Postgres rise (Neon's growth as the modern Postgres alternative to RDS), Supabase's developer-led adoption competing with Firebase, the Postgres-from-Oracle migration trend (driven by Oracle licensing costs), and the rapidly expanding Postgres extension ecosystem reshape the adjacent tech stack at PostgreSQL customer accounts in 2026. AI vector databases adjacent to pgvector, modern Postgres-anchored platforms, Postgres observability, Postgres migration services, and Postgres extension commercial support are the highest-velocity adjacent buying categories.
PostgreSQL's bundled coverage is exceptional for open-source relational database with rapidly expanding capabilities through extensions (pgvector for AI, TimescaleDB for time-series, Citus for distributed scale-out, PostGIS for geospatial). Depth gaps where specialist vendors regularly win include dedicated AI vector databases with deeper vector capabilities (Pinecone, Weaviate, Qdrant), modern serverless Postgres with branching (Neon), developer-led Postgres-anchored backend (Supabase), advanced Postgres observability, Postgres-specific FinOps for managed services, Oracle and SQL Server migration tooling, and competing OLTP databases.
BizzContacts isolates the PostgreSQL install base as a separately filterable cohort so vendors can run focused outbound into developer-led VP Engineering, CTO, Director of Database Engineering, and Director of Platform Engineering decision-makers without diluting their TAM with broader non-Postgres database audiences.
03Adoption
Companies Running PostgreSQL
PostgreSQL concentrates in developer-led companies (50-200,000+ employees) across B2B SaaS and software (the dominant vertical), FinTech and financial services, healthcare and HealthTech, e-commerce and DTC, gaming and gaming companies, media and entertainment, advertising and AdTech, telecommunications, government and public sector, education and EdTech, transportation and logistics, real estate and PropTech, manufacturing, energy and utilities, and other software-led industries. PostgreSQL is the default modern application database choice at developer-led organisations driven by its ACID compliance, SQL standards compliance, rich extension ecosystem, JSON support (rivaling NoSQL document databases), and absence of vendor lock-in (open source license).
Customer skew is broad with strong presence at all sizes. PostgreSQL is the default database choice at venture-backed B2B SaaS startups (often via Heroku Postgres, Neon, Supabase, or Render). Enterprise PostgreSQL adoption is exceptionally strong driven by Oracle-to-Postgres migrations (avoiding Oracle licensing costs) at financial services, healthcare, government, and other enterprise verticals. Amazon RDS for PostgreSQL is the largest single managed offering. Aurora PostgreSQL is the largest enterprise AWS choice. Cloud SQL is dominant on Google Cloud. Azure Database for PostgreSQL is dominant on Azure.

B2B SaaS and software account for approximately 28% of PostgreSQL customer count, the densest concentration globally driven by PostgreSQL being the de facto standard application database for venture-backed SaaS.
FinTech adoption is exceptionally strong for PostgreSQL driven by Oracle replacement (avoiding Oracle licensing costs) and ACID compliance for financial workloads.
Government and public sector adoption is exceptionally strong driven by no vendor lock-in (open source license), with USPS, NYC, EU government, and many federal agencies running PostgreSQL.
AI and ML companies are an exceptionally fast-growing PostgreSQL vertical with pgvector adoption for RAG applications. OpenAI, Anthropic, and other AI labs use PostgreSQL.
IoT companies use PostgreSQL with TimescaleDB extension for time-series telemetry, with TimescaleDB providing 10-100x query performance improvement on time-series workloads.
06Geo coverage
PostgreSQL Adoption by Country
PostgreSQL is truly global open-source database with the strongest community-led adoption pattern of any major database.
The United States accounts for approximately 45% of PostgreSQL customer count, the largest single market.
India is exceptionally strong at ~9% of customers reflecting India's vibrant B2B SaaS export ecosystem and developer community.

15Quick answers
PostgreSQL Buyer Intelligence: Quick Answers
Short, direct answer blocks optimised for AI search engines and featured snippets.
Q: How many companies use PostgreSQL?
A: Approximately 200,000+ enterprises and growing companies run PostgreSQL in production worldwide (across self-hosted and managed services). PostgreSQL is consistently the most-loved database in the Stack Overflow Developer Survey. BizzContacts verifies 23,500+ records.
Q: What is the largest managed PostgreSQL service?
A: Amazon RDS for PostgreSQL is the largest managed Postgres service globally. Amazon Aurora PostgreSQL is the largest enterprise managed Postgres choice on AWS.
Q: What is pgvector?
A: pgvector is the PostgreSQL extension for storing and querying vector embeddings, enabling AI/RAG applications natively in PostgreSQL. pgvector adoption exploded in 2024-2025 as enterprises evaluated AI vector databases.
Q: What is Neon?
A: Neon is a modern serverless PostgreSQL service with branching (similar to Git branches for databases), built from the ground up for the cloud as an alternative to RDS. Acquired by Databricks in 2025.
Q: What is Supabase?
A: Supabase is an open-source Firebase alternative built on PostgreSQL, providing Postgres database + authentication + storage + realtime + edge functions as a complete developer-led backend platform.
Q: How does PostgreSQL compare to MySQL?
A: Both are open-source RDBMS. PostgreSQL has stricter SQL standards compliance, richer data types (including JSON, arrays, custom types), more advanced query planner, and stronger ACID guarantees. MySQL has historically had wider adoption at scale (Facebook, YouTube) with simpler operations.
Q: How does PostgreSQL compare to MongoDB?
A: PostgreSQL is relational SQL with strong JSON support (JSONB). MongoDB is document-first NoSQL. PostgreSQL wins on ACID transactions, SQL ecosystem, and combining relational + JSON in single queries. MongoDB wins on flexible schema and document-first developer experience.
Q: How does PostgreSQL compare to Oracle Database?
A: PostgreSQL is open-source with no licensing costs. Oracle is commercial with significant licensing costs. PostgreSQL has reached feature parity with Oracle for most workloads. Oracle-to-Postgres migration is a significant trend driven by Oracle licensing cost avoidance.
