PEAK 15 Systems in Carlsbad's La Costa corridor develops cloud-native SaaS software purpose-built for multi-day tour operators, adventure travel companies, and destination management organizations. The platform unifies itinerary design, CRM, reservation management, and double-entry accounting in a single database, so a supplier rate change on one departure cascades through invoices, packing lists, and guest communications — end-to-end automation on the same El Camino Real tech corridor that houses Storm Brain's digital-marketing operation. Founded in 2006 and acquired by Fullsteam Operations in 2022, the company serves leisure-travel agencies and group-travel providers across North America and Europe from its 92009 headquarters near the Omni La Costa Resort. Revenue-cycle modules auto-generate supplier invoices and staged customer payment schedules, the same financial-operations layer that Carlsbad accounting practices such as Rockwater Associates reconcile for travel-industry clients. The reservation engine handles multi-leg itinerary pricing with variable-rate supplier contracts, auto-calculating per-passenger costs, commissions, and markup across inbound, outbound, group, and FIT departure types.
