The story
Hammr is a YC W23 vertical SaaS company building an all-in-one back-office platform for construction contractors — payroll, prevailing wage, certified payroll, time-tracking, scheduling, HR and benefits. Positioned as a replacement for ADP/Paychex/UKG/QuickBooks in construction, it competes on construction-specific workflows (Davis-Bacon, union rates, multi-rate pay). Embedded finance surface is limited today: payroll tax filings and benefits are packaged, but no evidence of card issuing, banking, lending, or a named payroll BaaS partner.
