## Summary

Retool is the leading low-code platform for building internal tools, used by 5,000+ companies including Amazon, DoorDash, and Brex to build custom internal software 10x faster than traditional development.

## Company Overview

Retool is a low-code development platform that allows software engineers and technical teams to build internal business applications dramatically faster than writing them from scratch. Founded in 2017 by David Hsu, Retool recognized that internal tools—admin panels, operations dashboards, data management interfaces—consume enormous engineering resources yet rarely deliver competitive advantage. The platform enables teams to build these tools by connecting drag-and-drop UI components to databases, APIs, and business logic, reducing development time from weeks to hours.

The platform supports integration with over 100 data sources including PostgreSQL, MySQL, MongoDB, Salesforce, Stripe, and REST APIs, allowing developers to query data and build workflows through a familiar JavaScript environment rather than a proprietary DSL. Retool's components include tables, forms, charts, and buttons that connect to backend queries, while still allowing custom JavaScript when flexibility is needed—striking a balance between ease of use and developer power that purely no-code tools sacrifice. Over 5,000 companies including Amazon, DoorDash, and Brex use Retool for their internal operations.

Retool has raised over $140M and was valued at $3.2B in its Series C round in 2021. The company competes in the internal tools and low-code market against products like Appsmith, Tooljet, and Budibase. Retool's moat is its depth of data source integrations, large developer community, and network effects from templates and components created by its user base that make it the default choice when engineering teams need to accelerate internal tool development.
