Problem

Sira addresses the administrative burden of running hourly, deskless teams across multiple job sites. These businesses often rely on paper, spreadsheets, text chains, and as many as seven disconnected tools for scheduling, time tracking, payroll, HR, compliance, and communication. The result is fragmented data, missed punches, compliance risk, language and technology barriers, and managers spending valuable time on repetitive coordination rather than managing people.

The killer use case is automating attendance and shift coverage: verifying timesheets, chasing missed clock-ins, and finding replacements when workers are late or absent. Sira’s YC profile estimates that a business can spend up to six hours a week verifying timesheets for a team of 15, while Sira reports that 63% of deskless workers still use paper timesheets. The economic payoff is reduced administrative labor, fewer payroll errors, and more reliable coverage across sites.

Product / Service

Sira is an AI-powered workforce-management and HR platform delivered through voice agents, text messaging, and a simple worker app. It contacts workers to correct missed clock-ins, fill open shifts, and answer questions; onboards new hires by collecting information and documents over text; builds schedules from management rules; and brings payroll, billing, HR, forms, expenses, and time tracking into one system.

The product is designed to meet workers where they are rather than require extensive software training. Geofencing can clock employees in and out when they arrive at or leave a job site, while AI helps enforce breaks, flag anomalies, complete payroll review, and communicate in multiple languages. For managers, the benefit is a virtual, always-on operations assistant that reduces manual corrections and coordination; for workers, it provides schedule notifications, one-tap clock-in, time-off requests, and direct access to answers.

Market

Sira competes in AI-native workforce management and HR software for hourly, deskless teams, positioning itself as an AI-native alternative to general-purpose systems such as Rippling and Gusto and workforce-specific tools such as 7shifts. Its initial focus is on overlooked small and medium-sized businesses in security, construction, landscaping, cleaning, and parking, where work is distributed across sites and traditional office-oriented HR software is a poor fit.

Sira is an early but commercially launched company rather than a confirmed pre-revenue concept. It was founded in 2025, entered Y Combinator’s Summer 2025 batch, and announced a $3.4 million seed round led by Y Combinator with Reach Capital, 1984 Ventures, and angel investors. The company reported more than 30 businesses using the product, over 600 hourly workers managed, and more than eight hours saved weekly; public materials reviewed do not disclose revenue, so the strongest evidence of traction is customer adoption, usage, and reported administrative savings rather than a reported sales figure.
