eMembership is a cloud union management platform from Winmill Software, designed from the ground up for labor unions rather than adapted from a generic CRM. Its data model reflects how unions actually work: members tied to employers, contracts, and dues classifications, with remittance arriving from multiple employers at once. Winmill owns and operates the physical infrastructure behind eMembership instead of renting capacity from a public cloud provider. The equipment sits in a colocation facility that holds SOC 1 and SOC 2 audit reports and ISO 27001 certification, and Winmill maintains HIPAA Security Rule and PCI DSS compliance for the eMembership environment. Data is encrypted in transit and at rest. Unions connect eMembership to the tools they already use through an open REST API and prebuilt integrations with QuickBooks, Great Plains, Mailchimp, SendGrid, Twilio, Stripe, PayPal, DocuSign, and others. Staff work in a web application, while members use a native iOS and Android app or a web portal that reads and writes the same database in real time. Functionality is split into 18 modules, so a union licenses only what it needs and adds more later. Two releases ship each year as part of the subscription. Pricing is set by module, never by seat or member count. Winmill has been building software since 1994 and launched eMembership in 2008. Today, 55+ labor unions across North America rely on it.

ContractSafe is AI-enabled contract management software that actually does what it promises, without the six-month implementation, per-seat charges, or admin overhead that makes most CLM tools their own kind of problem. If you've been through that cycle before (a tool that takes months to deploy, requires a dedicated admin, hides pricing behind a sales call, and still leaves contracts expiring without warning), ContractSafe is the way out. Search is Google-fast across every contract and attachment, including full OCR on scanned PDFs. The AI assistant automatically extracts key metadata, categorizes contracts by type, and answers plain-language questions about contract content. Smart Search understands your intent rather than requiring exact keywords. None of it needs configuration or a dedicated admin. It works out of the box. Pricing is published publicly. No "contact sales for a quote," no per-seat charges that penalize you for adding users, no implementation fees. Every plan includes unlimited users, automated renewal and key-date alerts, a dedicated Customer Success Manager, and free onboarding assistance. Higher-tier plans add approval workflows, redlining, and built-in e-signature. Security: hosted on AWS, SOC 2 Type II and ISO 27001 certified, HIPAA and GDPR compliant, with data residency options across the US, Canada, EU, and Australia. Most teams are fully operational within hours of signing up. Free trial, no credit card required.

Okyline is an Executable Data Design (EDD) platform focused on executable validation contracts and operational data quality control.
