What Zaddons does
Zaddons is a Montreal-based HR technology company that develops a suite of nine modular add-on products designed to embed directly within leading HR and workforce management platforms, including UKG (Dimensions and Pro WFM), ADP Workforce Now, and Shiftboard SchedulePro. Its product portfolio is organized into three categories: Bidding Solutions (Vacation, Schedule, Shift, and Job Bidding), Scheduling Tools (Call List, Fill Open Shift, Schedule Viewer, and Workplan Manager), and Employee Self-Service (Employee Billboard), plus a Full Suite bundle. The underlying technology uses configurable, rule-based multi-step automation engines and open APIs to address scheduling gaps that core HRIS platforms do not natively handle, particularly for organizations with complex union, seniority, and compliance requirements. All customer data remains centralized within the client's HRIS environment, with no separate login or data duplication.
Zaddons generates revenue primarily through a per-employee-per-month (PEPM) subscription SaaS model on annual billing cycles, with quote-based pricing rather than publicly disclosed rates. Implementation and configuration services are delivered through a network of certified partners (Axsium Group, Simms & Associates, Authentic Consulting Group, Improvizations, HR Path, IT Healthcare Leaders), creating a channel-driven GTM motion layered on top of direct enterprise field sales. Distribution occurs through embedded integrations and marketplace storefronts at UKG Marketplace and ADP Marketplace, supplemented by an OEM-style integration with Shiftboard. The company employs 11-50 people and is led by CEO Sébastien Massicotte and President Louis-Sébastien Laprise.
Zaddons serves enterprise and mid-market customers across healthcare, manufacturing, retail and hospitality, public sector, aviation, and distribution, with named customers including a major U.S. airline employing over 30,000 people. The company has raised $3.5 million in a single funding round in June 2024 led by Crédit Mutuel Equity with participation from FRAMEWORK, and has earned recognition including the UKG Collaborator of the Year award (2023), Great Place to Work Certification (2024), and ADP Marketplace partner status.

Zaddons competitors and assessment
Company assessmentDirect peers
- WorkJam: WorkJam provides an employee engagement and shift management platform that integrates with major HRIS/WFM systems (UKG, ADP, SAP) for frontline workforces. It is highly comparable to Zaddons because both target scheduling, shift bidding, and employee self-service workflows delivered as extensions on top of leading HRIS platforms.
- Deputy: Deputy offers shift scheduling, timesheets, and employee self-service software widely used by mid-market and enterprise shift-based employers. It overlaps directly with Zaddons' scheduling, shift bidding, and self-service capabilities, often positioning as an integration alongside UKG/ADP.
- Quinyx: Quinyx is a workforce management platform focused on AI-driven scheduling, shift bidding, and frontline employee engagement for enterprise and large multi-site employers. It competes for the same bidding/scheduling use cases that Zaddons addresses as add-ons to incumbent HRIS suites.
- When I Work: When I Work provides employee scheduling, shift trading, and time tracking primarily for shift-based businesses. Its shift bidding and self-service functionality overlaps meaningfully with Zaddons' Employee Billboard and Shift Bidding modules.
- 7shifts: 7shifts is an employee scheduling and workforce management platform built for restaurants and shift-based operators, offering shift swapping, auto-scheduling, and team communication. While more verticalized in hospitality, the core shift management and employee self-service capabilities are comparable to Zaddons' portfolio.
- Planday: Planday (part of Xero) provides shift planning, scheduling, and employee engagement for shift-based workforces. Its bidding and self-service features overlap with Zaddons' suite, and it serves comparable verticals such as hospitality, retail, and healthcare.
Emerging players
- Shiftboard: Shiftboard is both a Zaddons technology partner (OEM-embedded distribution) and a workforce scheduling platform in its own right, focused on mission-critical industries. It is relevant as a partial competitor for the same enterprise scheduling customers while also functioning as a distribution channel.
Broad incumbents
- UKG Dimensions / Pro WFM: UKG is the dominant workforce management and HRIS vendor that Zaddons extends. UKG represents both the most important distribution partner and the most significant competitive threat if it builds native bidding and advanced scheduling features into its core roadmap.
- ADP Workforce Now: ADP is one of the largest HR/payroll/workforce platforms globally and a Zaddons partner via the ADP Marketplace. Like UKG, ADP is both a critical distribution channel and a potential competitor that could absorb Zaddons-style functionality into its native offering.
- Reflexis (Blue Yonder): Reflexis, now part of Blue Yonder, provides workforce management solutions for retail and shift-based industries, including scheduling, task management, and store execution. It competes for similar enterprise scheduling budgets and customer profiles as Zaddons, particularly in retail and hospitality.
