What is Formstack?
Formstack is a no-code platform for building online forms, generating documents and collecting eSignatures, so organizations can turn paper and email processes into digital workflows. Its form builder handles everything from lead capture to applications and patient intake, with routing, conditional logic and payment fields. The company was founded in 2006, is based in Denver and says more than 32,000 organizations use its products. Teams use it to replace PDFs and email back-and-forth.
In June 2025 the company rebranded as Intellistack and launched Streamline, an AI-driven process automation product, but Formstack products remain on sale under their own name. The Formstack Suite bundles Forms, Documents and Sign, and Salesforce-native versions are available for teams that work inside Salesforce. Formstack is popular in healthcare, higher education and financial services, where HIPAA options and security controls matter.
