Companies & Work



Pulley is the cap table and equity management platform that helps founders and employees make smarter decisions about their equity.

For early stage companies, Pulley helps founders get started on hiring and fundraising, avoid expensive equity mistakes, and save thousands on legal fees. With Pulley, you can compare different funding scenarios, raise capital, and set up equity grants for employees.

Our tools help companies answer important questions such as:
1. How much of the company will I own after my next round?
2. How will pro-rata rights impact my ownership in future rounds?
3. How do I explain the value of equity to candidates?

Equity is a company's single most important asset. Pulley gives companies insights into their equity, so they can make smarter decisions around hiring and fundraising, while proactively staying ahead of tax filings and accounting.
