Last-mile delivery is the hardest, most expensive part of the supply chain. We make the last 30 seconds before departure count.
Dallas-based. Angel-backed. Building the re-optimization engine that regional carriers needed two decades ago.
Why Caleb Built Parcelarc
Caleb Harmon spent four years embedded with regional carrier operations teams across the DFW logistics corridor — first as a logistics consultant, then as head of operations for a regional parcel company serving the Dallas metro. What he watched happen every day at 6:45pm was the same: the route plan met reality, and someone had to manually rebuild routes against a clock.
The tools existed for upfront route planning. Nothing existed for the post-cutoff re-sequencing problem. Carriers were solving a real-time problem with static planning tools and phone calls to drivers.
Parcelarc was incorporated in early 2024 with a single thesis: the re-optimization problem deserves its own engine. Not a feature bolt-on to a routing product — a dedicated system built to ingest live constraints and push updated sequences in under 30 seconds.
The company raised an angel round in 2026 to build that engine, ship the driver app, and prove the model with regional carriers in the DFW market before expanding regionally.
What We Actually Believe
We don't ship dashboards that look impressive at demos but don't move operations. Every feature gets judged by one question: does a dispatcher spend less time doing this?
The product is designed for someone staring at a screen at 6:50pm with 8 minutes until vehicles leave. Not for the quarterly business review. Not for the investor tour.
Every algorithm decision is tested against real operational scenarios from the DFW carrier ecosystem. No lab benchmarks without field validation.
We use ranges and "designed for" language because we haven't run controlled trials across every carrier configuration. We're transparent about what's measured and what's modeled.
The DFW Hub Is Not Coincidence
Dallas-Fort Worth is one of the largest freight hubs in the country. More than 70% of the US population is within a 2-day ground delivery radius of DFW. That density creates specific last-mile problems — and a concentrated community of regional carriers who are building solutions to solve them in real time.
Being based here means our team has direct access to carrier ops teams, depot managers, and dispatch software vendors. We're not building from theory. We're building from conversations at 6pm on the loading dock.
