Close is a bootstrapped profitable 100% remote ~100 person team of thoughtful individuals who prioritize taking ownership and making a meaningful impact. We’re eager to make a product our customers fall in love with over and over again.
We 💛 small scaling businesses. Since 2013 we’ve been building a CRM that focuses on better communication without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern thoughtfully designed all-in-one communication-focused CRM.
Our backend
tech stack consists primarily of Python Flask web apps with our
TaskTiger scheduler handling many of the backend asynchronous task processing chores. Our data stores include MongoDB PostgreSQL Elasticsearch and Redis. The underlying infrastructure runs on AWS using a combination of managed services like EKS MSK RDS and ElasticCache and non-managed services running on EC2 instances. We have CI/CD pipelines that build Docker images run automated tests and deploy to Kubernetes clusters. We also use these images in our local development environment allowing coding locally against all of our services. We have a well-documented
public API that is consumed by our front-end JavaScript app as well as numerous integrations. Our infrastructure is heavily automated using Terraform Ansible and other AWS tools.
