About Luna Sol Group
A focused firm for consequential operating decisions.

Why Luna Sol exists
Recommendations do not create value. A business capable of running them does.
Luna Sol is built for the gap between an approved idea and an operation capable of delivering it.
Engagements begin with the executive commitment, make the evidence boundary explicit, and finish with owners, controls, and a cadence the team can sustain. The firm was founded in 2023 and has operated as a full-time advisory practice since January 2026.
Operating principles
A direct engagement model, designed for accountable action.
These principles govern how work is scoped, tested, implemented, and represented in public.
01
Truth before prescription
Reconcile the dashboard with workflow evidence and frontline reality before recommending action.
02
Decisions before activity
Define what leadership must choose, the evidence required, and the consequence of delay.
03
Mechanisms before theater
Build workflows, controls, ownership, and cadence that operators can use under pressure.
04
Capability before dependence
Leave the team able to run the system without permanent reliance on the advisor.
Four advisory areas
One operating thread, from performance pressure to durable control.
Each capability begins with a decision and ends with a mechanism the team can run.
01
Performance transformation
Resolve the operating mechanism behind unstable service, cost, quality, or throughput.
02
Operating model and scale
Build the workflows, accountabilities, and controls required to carry growth safely.
03
Transformation execution
Turn an approved strategy into sequenced work, accountable decisions, and verified operating value.
04
Digital operations
Translate operating mechanisms into technology-enabled workflows and decision products.
Industry focus
Depth where execution is the customer promise.
Luna Sol leads where the operating record is credible and adds specialist depth when the decision requires it.
01
Logistics and last mile
Network flow, service, capacity, partners, and unit economics.
02
Mobility and transportation
Dispatch, compliance, safety, and multi-market control.
03
