Close is a bootstrapped, profitable, 100% remote, ~90 person team of thoughtful individuals who value autonomy and impact. We’re eager to make a product our customers fall in love with over and over again.

We ❤️ startups & SMBs. Since 2013, we’ve been building a CRM that focuses on better communication, without the hassle of manual data entry or complex UI. Our goal: double the productivity of every sales rep.

Our backend tech stack currently 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. All of our compute runs through CI/CD pipelines that build Docker images, run automated tests and deploy to our Kubernetes clusters. Our backend primarily serves a well-documented public API that our front-end JavaScript app consumes. Our infrastructure is heavily automated using Terraform, Ansible and other AWS tools.

Our product development process is inspired by Shape Up. We❤️ open sourcing our code and ideas on our GitHub and onThe Making of Close, our behind-the-scenes Product & Engineering blog. Check out our projects like SocketShark, TaskTiger, LimitLion and ciso8601.
