What is Kombo?
Kombo expands its unified HR API into Payroll data models, opening a new data category for integration builders.
Kombo is a unified HR integration API shipping on a weekly changelog cadence, covering ATS, HRIS, LMS, and — as of August 30 — Payroll data models. Recent releases have a dual rhythm: graduating integrations from beta to General Availability in bulk while simultaneously adding new ones (Atlas, Skello, Zellis, Talent360). Integration depth is also growing, with Workday performance overhauls, Lever high-performance sync modes, and Greenhouse scorecard sync all landing in August.
What is Soon?
Soon is rebuilding its auto-scheduler and AI assistant on a steady SMB-to-enterprise track.
Soon ships small, focused workforce-management releases roughly every two to four weeks. Recent work centers on the auto-scheduler (Activity Scheduler V2 with intraday and baseline-aware logic) and the AI assistant (v2 with real-time schedule insights), alongside table-stakes enterprise features like SCIM directory sync, SLA/AHT lines on workload graphs, and a file-upload path for converting outside schedules into Soon schedules.

Kombo

Kombo expands its unified HR API into Payroll data models, opening a new data category for integration builders.
◆ Current state
Kombo is a unified HR integration API shipping on a weekly changelog cadence, covering ATS, HRIS, LMS, and — as of August 30 — Payroll data models. Recent releases have a dual rhythm: graduating integrations from beta to General Availability in bulk while simultaneously adding new ones (Atlas, Skello, Zellis, Talent360). Integration depth is also growing, with Workday performance overhauls, Lever high-performance sync modes, and Greenhouse scorecard sync all landing in August.
◆ Where it's heading
The product is expanding its data model surface area (Payroll is the newest) while tightening the reliability of existing connections. AI-assisted formula generation for custom field mapping reduces the configuration burden for complex data transformations. The trajectory is toward a comprehensive HR data fabric that covers the full employment data stack rather than just ATS/HRIS connectors.
◆ Prediction
Payroll data model launch typically precedes specific payroll integrations — expect Gusto, ADP, or Paychex connectors in the next 30-60 days. Advanced Mappings AI assistance will likely expand to more formula types and field contexts as adoption grows.
Soon
0.0HR
Soon is rebuilding its auto-scheduler and AI assistant on a steady SMB-to-enterprise track.
◆ Current state
Soon ships small, focused workforce-management releases roughly every two to four weeks. Recent work centers on the auto-scheduler (Activity Scheduler V2 with intraday and baseline-aware logic) and the AI assistant (v2 with real-time schedule insights), alongside table-stakes enterprise features like SCIM directory sync, SLA/AHT lines on workload graphs, and a file-upload path for converting outside schedules into Soon schedules.
◆ Where it's heading
Three threads run in parallel. The scheduling engine is being matured — V2 of both Activity Scheduler and the Intraday Solver — to handle real contact-center constraints. The AI assistant is being made reliable enough to lean on for live schedule queries. Enterprise readiness is being filled in (SCIM, account setup, deletion flows). Each release is small, but the direction is consistent.
◆ Prediction
Expect the AI assistant and the scheduler to converge — natural-language scheduling moves rather than just queries. Continued enterprise-feature buildout (audit logs, SSO refinements, role granularity) is likely as Soon competes for larger contact-center accounts.
