Overview
Firstbase (firstbase.io) is a startup operating platform that helps entrepreneurs anywhere in the world incorporate and run a US business. Founded in 2019 and part of Y Combinator's Winter 2021 batch, its flagship product, Firstbase Start, automates US company formation, letting founders incorporate an LLC or C-Corporation in any state. The platform bundles incorporation with ongoing back-office services so non-US and US founders can launch and operate without navigating fragmented providers.
Products
Beyond formation, Firstbase offers registered agent services in all 50 states through its own licensed entities, plus compliance management (annual reports and franchise tax filings), bookkeeping, and tax support. Its Firstbase Agent feature handles ongoing state compliance automatically. The company reports facilitating tens of thousands of incorporations from nearly 200 countries.
Funding
Firstbase has raised around $65 million across multiple rounds, including a $50 million Series B in March 2022 led by Kleiner Perkins, with participation from Andreessen Horowitz (a16z), Alpaca, and others.
