In 2006, a software developer named Ade Olonoh kept running into the same wall. Every website he built, every app he shipped, needed a form - a contact box, a signup, a survey. And every time, he had to hand-code it from scratch. So he built a tool that would do it once and never make him do it again. That tool became Formstack, and the small annoyance behind it turned out to be a problem shared by tens of thousands of businesses.
Two decades later, Formstack is a no-code platform that lets anyone - not just engineers - build online forms, generate documents, and collect legally binding signatures, then chain those pieces into automated workflows. It runs inside hospitals, universities, insurance offices, and marketing teams. Its customer list includes the Cleveland Clinic, Netflix, and the NHL. And in November 2021, investors valued the company at roughly a billion dollars.
The boring problem worth a billion dollars
Forms are not glamorous. Nobody wakes up excited to fill out a patient intake sheet or a vendor onboarding packet. But every organization drowns in them, and the work of collecting that data - then routing it, formatting it into documents, and getting it signed - eats hours that no one wants to spend. Formstack's bet was simple: make that busywork buildable by the person who actually has the problem, rather than filing an IT ticket and waiting two weeks for engineering.
That framing is the whole company. A marketer can spin up a lead-capture form. An HR manager can build a new-hire packet that generates an offer letter and collects a signature. A nurse can put together a HIPAA-compliant intake form without touching a line of code. The technical skill is abstracted away; what's left is the task.

How the suite fits together
Formstack started as a form builder, then grew into three products that snap together. Forms captures the data. Documents (originally a separate product called WebMerge) turns that data into a branded PDF or contract. Sign collects the signature. Workflows is the visual builder that connects all three into one sequence - no code, no copy-paste between tools.
The classic example: a new employee fills out one form, the system builds a company-branded offer document, and both the hire and their manager review and sign - start to finish without a human moving files around.
Who actually pays for this
Formstack sells to businesses, not consumers, on a subscription model - tiered plans by user and organization, with enterprise options that add HIPAA compliance and deeper integrations. The customer base skews toward regulated and process-heavy industries: healthcare, higher education, financial services, insurance, government, and nonprofits. These are the places where a form isn't just a form - it's a compliance requirement, an audit trail, a signature that has to hold up.
The strategy is land-and-expand: a team adopts Forms, then adds Documents, then Sign, then Workflows as the value compounds. Once a hospital's intake process or a university's admissions flow runs on Formstack, switching costs are high and churn is low. The product isn't a feature - it's the plumbing.
Where it sits in a crowded market
The form-building space is busy. Typeform owns the sleek, conversational survey. Google Forms and Microsoft Forms own free and good-enough. Jotform, GoFormz, and GoCanvas compete on features and mobile. DocuSign and Dropbox Sign own signatures; Conga and PandaDoc own document generation. Formstack's answer to the crowd is integration: instead of being the best single tool, it aims to be the one platform where capture, generate, and sign live in a single automated flow - with enterprise-grade security and a native tie into Salesforce that lets teams build all of it without leaving their CRM.

The Formspring footnote
Here's the fact that surprises people. Formstack and Formspring.me - the viral 2010 social Q&A site where teenagers answered anonymous questions - came from the same company. In 2009 the team launched formspring.me as a side experiment. It blew up. In 2010 it was spun out as its own company with its own team, and to end the confusion, FormSpring.com renamed itself Formstack. One sibling chased social-media virality; the other quietly kept building business forms. Two decades on, it's clear which bet aged better.
The Indiana story, and the pivot to AI
For most of its life, Formstack was headquartered in Fishers, Indiana - not a coastal tech hub - and built a remote-first workforce with more than half its roughly 250 employees working from home. Growth-equity firm PSG invested in 2018, and the company more than tripled its revenue and made a string of acquisitions before the 2021 round led by PSG and Silversmith Capital Partners. The path wasn't all upward: in May 2023, amid the broader tech downturn, Formstack cut more than 40% of its staff.
In June 2025 came the biggest reinvention yet. The parent company rebranded from Formstack to Intellistack, moved its headquarters to Denver, and launched Streamline - an AI-driven, no-code process-automation platform pitched on a specific idea: build secure, data-rich workflows across the systems you already use, without migrating or hoarding the data. The Formstack products continue to be sold and supported under their own name, now as a line inside a larger company.
What you can actually do with it
Strip away the corporate framing and Formstack is a set of practical shortcuts. Collect patient information without printing a thing. Turn a sales inquiry into a signed contract in a single sitting. Run event registrations, take payments through Stripe or PayPal, sync submissions into HubSpot or Salesforce, dump files into Amazon S3, and connect the rest through Zapier. For a marketer it's conversion tooling; for an operations lead it's a way to delete the phrase "let me loop in engineering." The value it sells isn't features - it's time returned.
