About FieldSubBuilt by subs.
Built by subs.
Built like subs build.
We started in the field. We're still building like we're in the field — with crews, office staff, and clients in the loop on every release.
Built by a contractor, for contractors
FieldSub was co-founded by Samuel Matos, who spent 15 years building and running a subcontracting company in the United States. Unlike software built by product teams with no field experience, FieldSub was designed from the ground up by someone who managed crews, wrote estimates from a truck, and tracked jobs across dozens of active projects simultaneously. The platform is the only construction CRM built specifically for Hispanic subcontractors, with Spanish as the primary language — not a translation added as an afterthought.
02
Bilingual is the floor, not a setting.
Spanish-speaking crews are first-class users from day one — translation isn't bolted on.
03
We answer the phone.
Setup, support, and roadmap — humans, not chatbots, on every conversation.
Founder note
"We were rebuilding the same job in three different tools. So we stopped, and built one tool that actually works the way we work."
