How we work in Logistics
Logistics software has to hold up at operational scale, every day. We embedded engineers into SimpliRoute's route optimization platform, used by 1,200+ enterprise clients, and were in production by day 5; for Mindel we built AI voice agents and refactored the platform behind the 24/7 phone service of GLS and MRW parcel branches in Spain.

We've worked on both sides of real estate tech: the agent tools of a global brokerage and a startup's platform built from zero. For Keller Williams Latin America we modernized the agent portal of a 180,000+ agent network; for Mission, a NY real estate startup, we turned a raw product vision into a full platform and kept shipping month after month.
