Intellistack

Intellistack is an AI-native, no-code process automation platform built for organizations that need to redesign manual workflows, manage contracts end-to-end, and connect data across systems—without writing code. Originally founded in 2006 as Formstack, the company rebranded to Intellistack in 2025 to reflect its expanded focus on intelligent, AI-powered workflow automation. The platform serves industries including healthcare, higher education, financial services, and hospitality.

What It Is

Intellistack delivers two primary product lines: Intellistack Streamline, its flagship AI-native workflow automation platform, and Formstack, a suite of productivity tools covering forms, document generation, and eSignatures. Streamline is positioned as a consolidation play—replacing multiple niche applications with a single, connected platform that uses AI throughout its architecture rather than layering AI on top of existing tools. The company describes this as being "AI-native," meaning AI is designed into the platform from the ground up.

From Formstack to Intellistack

The company was founded in 2006 as Formstack, pioneering online form building before expanding into document generation and eSignature automation. In 2025, the company unveiled the Intellistack brand and launched Intellistack Streamline as its next-generation platform. The Formstack product line continues to operate under the Intellistack umbrella, serving customers who need standalone productivity tools for forms, documents, and eSign workflows. This lineage gives Intellistack a multi-decade track record in workplace productivity technology.

Core Platform Capabilities

Intellistack Streamline focuses on several key workflow categories:

• No-code workflow builder — Visual, drag-and-drop process design with conditional routing and approval logic
• Contract Lifecycle Management (CLM) — End-to-end contract workflows covering generation, redlining, collaboration, and final signature in one platform
• Data fabric and integrations — Connects multiple data sources (including EHR systems for healthcare) to power automated workflows
• AI-powered features — Includes a Playbook Assistant for legal teams and AI-driven redline summarization directly into Salesforce
• Formstack productivity tools — Forms, Documents, Sign, and Salesforce-native products for teams needing targeted productivity solutions

Industries and Use Cases

Intellistack targets regulated and data-intensive industries. Healthcare is a primary vertical, with the platform supporting patient intake, EHR data access, and care continuum workflows. Higher education is a second named vertical, addressing admissions and administrative process automation. The platform also serves financial services, hospitality, and software and technology companies. The company publishes use-case content covering loan applications, contract management, and community data collection.

Update: May 2026 Features Release

The company published a "New Intellistack Features – May 2026" product update, indicating active development and regular release cadence. A Playbook Assistant feature for legal teams was also recently announced, enabling legal playbooks to be surfaced across an organization. These releases signal continued investment in AI-assisted workflow and legal automation capabilities.

Scale and Organizational Footprint

The Intellistack website states the platform is trusted by more than 32,000 organizations worldwide over more than 20 years—a vendor-published claim. The company maintains offices in Denver, Indianapolis, Los Angeles, Menlo Park, Kraków, Sydney, and London, reflecting a global operational footprint. Leadership includes CEO Aled Miles OBE and a Healthcare Advisory Board with members drawn from Providence, NHS England, Ernst & Young, and Welsh Government health leadership.
