+Gruntwork Account Factory allows you to vend new AWS accounts with best practice account baselines.
+
+For enterprise customers new accounts can be created with their own delegated infrastructure repositories. This allows developer teams to self-service deploy their own infrastructure within the bounds of IAM roles controlled in your central repository.
+
+Account Factory is built into Gruntwork Pipelines. New account requests are tracked in git as IaC, triggering Terragrunt plans and applies to provision and baseline the new account.
