What is it
What Is the Heroku Customers List?
The Heroku customers list is a verified, regularly refreshed database of companies (typically 20-50,000+ employees) running Heroku in production, with named VP Engineering, CTO, Director of Platform Engineering, Director of DevOps, and engineering leadership at each account. Every record on the BizzContacts Heroku list is tagged with the specific Heroku products in production (Heroku Platform, Heroku Postgres, Heroku Redis, Heroku Kafka, Heroku Connect, Heroku Private Spaces, Heroku Shield, Heroku Enterprise, Heroku Pipelines, specific Add-ons Marketplace ISV services), company firmographics, industry mix, employee count, Salesforce ecosystem cross-reference (Heroku Connect customers), and Heroku tier where derivable.
The list feeds outbound prospecting for modern PaaS alternatives (Vercel, Render, Railway, Fly.io, DigitalOcean App Platform, Cloudflare Workers, AWS Elastic Beanstalk, Google Cloud Run, Azure Container Apps), managed PostgreSQL alternatives to Heroku Postgres (Neon, Supabase, Crunchy Bridge, Amazon RDS, Aurora, Cloud SQL), modern application platforms, container orchestration platforms (Amazon EKS, GKE, AKS), observability and APM (Datadog, New Relic, Honeycomb, Sentry), CI/CD platforms (GitHub Actions, CircleCI, Buildkite), modern Postgres extensions (TimescaleDB, Citus, PostgREST), AI-native developer platforms (Vercel AI SDK, Modal, Replicate, Anyscale), and competing developer-first PaaS platforms targeting Heroku displacement. Records ship with company firmographics, named decision-makers, and audit-trail metadata.
02Definition
Why a Heroku Customer List Matters in 2026
The modern PaaS competitive landscape (Vercel, Render, Railway, Fly.io explosion), the increasingly active Heroku displacement campaigns from these challengers, and Salesforce's ongoing post-2022-pricing-changes investment in Heroku enterprise are reshaping the adjacent tech stack at Heroku customer accounts in 2026. Modern PaaS alternatives, modern managed Postgres, observability extensions, and AI-native developer platforms are the highest-velocity adjacent buying categories.
Heroku's bundled coverage is exceptional for developer-first PaaS with mature managed databases and Salesforce ecosystem integration. Depth gaps where specialist vendors regularly win include modern PaaS with edge-native architectures and lower per-dyno cost, modern managed PostgreSQL with branching and serverless, advanced observability and tracing, AI-native developer tools, container orchestration at enterprise scale, modern CI/CD with deeper Heroku integration, and direct PaaS competitors with simpler pricing structures.
BizzContacts isolates the Heroku install base as a separately filterable cohort so vendors can run focused outbound into VP Engineering, CTO, and Director of Platform Engineering decision-makers without diluting their TAM with broader hyperscaler AWS/Azure/GCP targets.
03Adoption
Companies Running Heroku
Heroku concentrates in developer-led companies (20-50,000+ employees) across B2B SaaS and software, FinTech and financial services SaaS, healthcare technology, e-commerce and DTC, EdTech and online learning, MarTech and AdTech, gaming and social, on-demand services, travel and hospitality, media and entertainment, government technology, life sciences and biotech, professional services SaaS, and other software-led industries. The platform's developer-friendly experience, git-push deployment, mature managed Postgres, Salesforce Connect integration, and 12-Factor App methodology heritage distinguish it from hyperscaler IaaS alternatives and modern PaaS challengers.
Customer skew is mid-market and growing enterprise (50-5,000 employees, approximately 65% of customer count) with strong presence at SMB and growing startup (20-49 employees) and meaningful enterprise presence (5,000+ employees). Heroku has particularly strong adoption in Ruby on Rails B2B SaaS startups (the original Heroku customer cohort), Salesforce ISV partners (using Heroku Connect), and healthcare technology companies (using Heroku Shield for HIPAA).

B2B SaaS and software account for approximately 35% of Heroku customer count, the densest concentration globally driven by Ruby on Rails B2B SaaS heritage.

Above 5,000 employees, Heroku Enterprise serves specific use cases (Salesforce ISV partners, HIPAA-compliant healthcare) where Connect and Shield provide differentiation.
