Driving better services and better journeys
Grant Klein Advisory brings 30 years of hands-on experience across the UK, Europe and North America to help transport organisations deliver better services, smarter investments and happier customers.

Designing services that work in the real world
We specialise in crafting new customer offers that blend business savvy with technical know-how – especially in complex, multi-stakeholder environments.
We don’t just design services; we help you to embed them into the fabric of cities and regions. That means integrating with other modes of travel, promoting active mobility, and helping clients build smart, sustainable systems that work for real people in real places.
We thrive on ambiguity. If your challenge is fuzzy, we bring structure. If your options are unclear, we help you choose wisely.

From AI and governance innovation to bold new service designs, we’re here to help you shake things up.

Helping teams navigate complexity
We’re especially strong at the public-private interface, offering strategic advice that’s fast, focused and free from hidden agendas. We don’t hang around to upsell – we help your team shine and move on.
Our work often crosses into adjacent sectors – environment, education, national security and international aid – because transport is part of a bigger societal puzzle.
Whether you’re a startup or a government department, we help you make sense of the mess and move forward with clarity.

Where strategy meets partnership
We’ve worked with FTSE250 execs, international corporations and senior government leaders. Our sweet spot? Helping these worlds collaborate better so both achieve their goals.

Decisions that drive progress
Transport is changing fast with tight budgets, climate goals to meet and rising customer expectations. We help you make smart, evidence-based decisions that balance risk and reward.
Make your next decision a smart one.
