Warp

Warp is an AI-native payroll, compliance, and benefits platform built for US companies from 10 to 5,000+ employees. Operated by Poaster Technologies Inc. (doing business as Warp, formerly Interstellar Co. at joinwarp.com, now at warp.co), the platform positions itself as self-driving employee management: AI agents autonomously open state tax accounts when new hires are added, resolve compliance notices, reconcile benefits, and process multi-state payroll across 10,000+ tax jurisdictions without requiring HR intervention. Over 1,000 companies run on Warp, with customers including Greptile, Paraform, and Julius AI. The platform covers US payroll, global contractor payments in 200+ countries, benefits administration, IT management, expense reimbursements, and compliance monitoring in a single system. Warp integrates natively with a broad set of business tools. Accounting integrations include QuickBooks, Xero, NetSuite, and Rillet, with automatic journal entries posted after every payroll run. Okta handles SSO and SCIM provisioning. Slack receives payroll notifications, tax alerts, and deadline reminders, with a dedicated Slack Agent Integration at the Pro tier. Checkr handles background checks. The Warp IT add-on covers Google Workspace provisioning, Okta app provisioning, and MDM device management. REST API, CLI, and MCP integration are available starting from the Starter tier, enabling AI-agent-to-agent connectivity and custom workflow automation. Enterprise tier adds webhooks, custom SLAs, and higher API limits. Integration categories span accounting, ATS, background checks, benefits, communication, compensation management, compliance, HRIS, insurance, IT, and SSO. Pricing verified live on warp.co/pricing as of June 2026. Three tiers plus add-ons. Starter at $35 per person per month plus an $89 per month platform fee covers next-day payroll with AutoPay, multi-state payroll and compliance in up to 3 states, automated tax filing and state tax registrations, medical, dental, and vision benefits, 401(k) integration, global contractors in 200+ countries, expense reimbursements, PTO tracking, LMS and training, REST API, CLI, and MCP integration, and background checks with Checkr. Pro at $50 per person per month plus a $129 per month platform fee adds SSO and role-based access controls, Slack Agent Integration, compliance in all 50 states, compensation benchmarking, HSA and FSA, and 24/7 dedicated support. Enterprise is custom-quoted with annual billing only and adds unlimited employees, NetSuite and custom ERP integrations, multi-entity support, enterprise API module with webhooks and SLAs, audit logs and compliance reporting, a dedicated success manager, and custom onboarding and security reviews. Add-ons available on any tier: Warp IT at $15 per person per month (Google Workspace provisioning, Okta app provisioning, MDM) and Time Tracking at $5 per tracked person per month. Security confirmed on warp.co/security: SOC 2 Type II independently audited with continuous monitoring via Oneleet. GDPR-Ready with data processing agreements available. Warp is not the right fit for companies needing full-time international employees rather than contractors: global payroll covers contractors in 200+ countries but companies hiring full-time employees internationally should evaluate Rippling Global or Deel EOR (from $599/employee/month). Teams needing a lighter payroll-only solution at lower cost should evaluate Gusto Simple ($49/month plus $6/employee). The Starter tier limits multi-state compliance to 3 states: companies operating in more states must upgrade to Pro ($50/person plus $129 platform fee) for all 50 states coverage, a meaningful cost increase for rapidly expanding companies. Organizations requiring HIPAA certification beyond a BAA or ISO 27001 should note Warp currently holds SOC 2 Type II and GDPR-Ready status only. Current state Q2 2026: Warp launched Warp Fabric, connecting HR data across the broader business operations stack. The pricing structure was reorganized from Pro/Premium to Starter/Pro tiers with new add-ons for IT management ($15/person/month) and Time Tracking ($5/tracked person/month). MCP integration is now available starting from the Starter tier alongside REST API and CLI access. The company rebranded from joinwarp.com to warp.co. SOC 2 Type II independently audited with continuous monitoring via Oneleet. G2 rating 4.4/5 across 32 verified reviews.
