An advisory
firm, by design.
EV Fleet Services is powered by SolSombra, a boutique sustainability, energy transition and fleet advisory founded by Landon Kahn in 2022. We help teams make operationally sound planning, charging and procurement decisions.
Operational
reality first.
Operations before products
We start with your operational reality, not a product catalogue. Routes, depots, drivers and duty cycles are the inputs.
Transparent recommendations
Recommendations are documented against agreed operational and commercial criteria. Relevant relationships are disclosed at engagement start.
Evidence you can take to a board
Our outputs are designed for governance, financial and operational review. Financial models show their assumptions, sources and limits.
In the room for rollout
We stay with you through execution. Transitions stumble in implementation, not in strategy.

Landon Kahn,
CEO and Principal
Advisor.
Landon founded SolSombra in 2022 and brings 19+ years of experience across sustainability, energy and fleet transition, supported by a global network of EV and fleet experts.
The practice has worked with dozens of organisations, including SMEs, not-for-profits, corporates, ASX100 companies, councils and government teams. Engagements begin with the operating requirement; assumptions, option criteria and relevant commercial relationships are documented so your team can review the advice.
