## About Us [Close](https: close.com ) is a bootstrapped profitable 100% remote ~100 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 ❤️ 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 all-in-one AI-powered and communication-focused CRM. Our app’s frontend is a single-page TypeScript web app mostly written in React (originally built with Backbone.js). Our mobile app is built using React Native. We bundle with Vite and target only modern browsers. We test with Vitest React Testing Library Playwright and Chromatic (VRT). Our UI updates in near real-time and is styled via CSS modules and takes advantage of fun technologies like Websockets and WebRTC. We care about performance (e.g. route-based code splitting or skeleton UI) maintainability and testability of our frontend code. Our product development process is inspired by [Shape Up](https: basecamp.com shapeup). We sweat the UI UX details and work collaboratively with the Product team throughout the design process. This means diving into lo-fi wireframes and communicating continuously when those ideas are brought to life using Figma and code (Storybook). Our frontend app is built on top of our REST API & GraphQL endpoints. Our backend [tech stack](https: stackshare.io close-crm close) consists of Python Flask MongoDB Postgres Elasticsearch and Redis. We run our services in Docker on AWS. We ❤️ open sourcing our code and ideas on [our GitHub](https: github.com closeio) and on [The Making of Close](https: making.close.com) our behind-the-scenes Product & Engineering blog.
