What is it
What Is the AWS Customers List?
The AWS customers list is a verified, regularly refreshed database of paying enterprise organisations running production workloads on Amazon Web Services, with named CTO, VP Engineering, Cloud Architect, and Platform Engineering decision-makers at each account. Every record on the BizzContacts AWS list is tagged with the specific AWS services in production (EC2, S3, Lambda, RDS, Redshift, EKS, Bedrock, SageMaker, etc.), AWS support tier (Developer, Business, Enterprise On-Ramp, Enterprise), AWS Partner Network partner where publicly disclosed, and the AWS regions deployed.
The list feeds outbound prospecting for AWS Marketplace ISVs, DevOps tooling vendors, observability and APM vendors, cloud security and CSPM vendors, AI and ML platform competitors, FinOps and cost management vendors, data engineering tools, and competing cloud platforms (Microsoft Azure, Google Cloud, Oracle OCI). Records ship with company firmographics, named decision-makers, and audit-trail metadata.
02Definition
Why an AWS Customer List Matters in 2026
Amazon Bedrock, generative AI agents, Amazon Q, and the continued GPU capacity expansion are reshaping the adjacent cloud stack at every AWS account. AI infrastructure, AI agent frameworks, AI security and governance, GPU-as-a-service, and vector databases are all categories where AI-native point solutions are competing aggressively at AWS customer accounts.
AWS spans an exceptionally broad service catalog but depth varies by service. EC2, S3, and Lambda are dominant. RDS competes with specialist databases. SageMaker competes with Databricks ML, Hugging Face, and Vertex AI. Bedrock competes with OpenAI, Anthropic direct API, and Google AI. Each depth gap is where specialist vendors regularly win at AWS customer accounts.
BizzContacts isolates the AWS install base as a separately filterable cohort so vendors can run focused outbound into CTOs, VP Engineering, and Cloud Architects without diluting their TAM with Azure or GCP targets.
03Adoption
Companies Running AWS
AWS concentrates at organisations with significant cloud workloads, modern application architectures, and engineering-led infrastructure decisions. Software and SaaS, financial services and FinTech, media and streaming, gaming, e-commerce and DTC, life sciences and genomics, automotive and mobility, telecommunications, public sector, and healthcare technology all show heavy AWS adoption.
Customer skew spans every segment from startups on the AWS Activate program through global Fortune 100 with eight-figure annual AWS bills. The BizzContacts list focuses on the paying enterprise tier (Business support and above) where outbound vendor sales have predictable ROI.

Software and SaaS account for approximately 38% of AWS enterprise customers, the densest single-industry concentration.
Generative AI workloads (Bedrock, SageMaker) are the fastest-growing AWS service category by net new spend in 2026.
AWS GovCloud and FedRAMP-authorised regions have driven explosive AWS growth in the US public sector and federal contractor space through 2026.
Life sciences and genomics have become a defining AWS vertical, with HealthOmics and HPC-on-EC2 anchoring multi-petabyte genomics pipelines.
06Geo coverage
AWS Adoption by Country
AWS has the most extensive cloud region footprint of any provider with 33+ regions across six continents.
The United States accounts for approximately 45% of AWS enterprise customer organisations, the densest concentration globally.
AWS GovCloud (US) workloads are growing fastest in the federal contractor space, with FedRAMP High and IL5/IL6 authorisations expanding the addressable market.
Latin America (Brazil, Mexico) growth is driven by the Sao Paulo region buildout and FinTech adoption.
AWS Wavelength Zones for 5G and edge workloads are driving telecom adoption in the US, UK, Japan, and South Korea.
07US footprint
AWS Customers by US State
US AWS deployments cluster in California, Virginia, Washington, Texas, and New York with strong representation across all 50 states.
California's AWS density is driven by Bay Area SaaS, LA media and gaming, and San Diego biotech.
Virginia hosts the AWS US-East-1 region (Northern Virginia) plus the densest US federal AWS cluster on AWS GovCloud.
Washington state hosts the AWS US-West-2 region (Oregon proximity) plus Amazon itself, Microsoft, T-Mobile US, and Costco.
Florida and Georgia host fast-growing FinTech and AdTech AWS clusters anchored by Miami crypto and Atlanta payments.
08Segmentation
AWS Customer Size Distribution
AWS covers every customer size from startups through global Fortune 100. The BizzContacts paying-enterprise list focuses on Business and Enterprise support customers where outbound has predictable ROI.
Lower mid-market and upper mid-market customers (100 to 1,999 employees) are the densest paying AWS cohort and the highest-velocity outbound segment for AWS Marketplace ISVs and adjacent tooling vendors.
09Buyer titles
Decision-Makers at AWS Customer Accounts
AWS buying decisions cluster around engineering and infrastructure leadership, with FinOps and security as supporting roles. CTOs and VP Engineering are the most common executive sponsors at SaaS customers; Cloud Architects and Platform Engineering Directors are the day-to-day platform owners.
The Director of Platform Engineering and Principal Cloud Architect are the highest-conversion outbound entry points at AWS customer accounts. They own service selection and platform extension decisions and have strong influence on adjacent tooling purchases. CTO and VP Engineering work best for strategic transformation pitches.

How we build the data
How the AWS Customers List Data Is Sourced
The BizzContacts AWS customers list is built from a multi-channel research pipeline focused on confirming AWS service footprint, support tier, region usage, and Partner Network relationships, plus tagging each record with verified engineering and platform decision-makers.
A record is shipped only when at least two independent sources confirm the AWS deployment and the decision-maker contact is verified by the research desk within the trailing 30 days.
Customer voice
What Outbound Teams Say About BizzContacts AWS Data
We sell DevOps tooling. Most data vendors give us CTOs at random tech companies. BizzContacts gave us the actual Director of Platform Engineering at 1,800 AWS-paying accounts. Reply rate jumped from 1.4% to 7.9%.
Service-level tagging for Bedrock customers was the differentiator. Our AI governance tool only fits accounts with GenAI in production. BizzContacts isolated them precisely.
Enterprise support tier filtering meant we only pitched accounts with $1M+ annual AWS spend. Our average deal size doubled.
