20 years of building.
A lifetime of intent.

With over 20 years of professional experience, I've spent my career learning how businesses actually work — from the inside. As a Director at an established energy consultancy, I've built and led teams, grown operations from the ground up, and developed a sharp commercial instinct across one of the UK's most dynamic sectors.

Outside of that, I've been quietly building something of my own. The Millers Group is the SPV I founded for my family — a structured vehicle for long-term investing across early-stage startups, property, and SEIS & EIS opportunities. It's how I put my convictions to work beyond the day job.

I'm also currently going through the process with Connectd to become a registered board advisor — bringing my commercial experience to bear for the founders and businesses that need it most.

The Millers Group is the platform for everything I'm growing into: an active investor, a straight-talking mentor, and a business growth partner for those ready to move forward.

"I don't believe in waiting until everything is perfect. The best time to plant the right seeds — personally, professionally, financially — is always now."
— Jason Miller, The Millers Group

Three areas.
One consistent intent.

Everything I do is built around one idea: helping people and capital move in the right direction.

01

Investing

Deploying capital thoughtfully across a range of opportunities — with a focus on early-stage businesses and structured vehicles.

  • SEIS & EIS investment opportunities
  • Consortium and co-investment deals
  • Property investment
  • SPV structure & family wealth planning
  • Core financial instruments guidance
02

Mentoring

One-to-one support for those who want a trusted, experienced voice in their corner — without the corporate red tape.

  • Early-stage career development
  • Professional clarity & direction
  • Navigating career transitions
  • Building confidence & executive presence
  • Founder support & accountability
03

Business Growth

Strategic thinking for small businesses and startups that need more than good intentions — they need a clear plan and someone who's done it.

  • Business strategy & growth planning
  • Commercial awareness & market positioning
  • Energy sector consultancy
  • Introductions to investors & networks
  • Accountability & execution coaching

Empowering people to
grow with intention.

The Millers Group exists to close the gap between ambition and action. Too many talented people stall — not because they lack ideas, but because they lack structure, support and the right connections.

Whether that's an investor looking to deploy capital more strategically, a young professional who needs a mentor who truly listens, or a small business owner trying to move from survival mode to scale — we meet people where they are.

This is a long-term endeavour. Built with integrity. Driven by genuine curiosity about what people can become when they're properly supported.

Integrity Long-term Thinking Genuine Connection Purposeful Growth

The right fit matters.

I work with a small number of people at a time — so the match needs to be right for both of us.

01

Startup Founders

Early-stage founders who need a credible voice, investor introductions, and someone to pressure-test their thinking before they go to market.

02

Early-Career Professionals

Ambitious individuals in the first decade of their career who want to accelerate their growth with guidance that's honest, practical and personal.

03

Small Business Owners

Business owners who've outgrown the startup phase but need clearer strategy, better structure, and a sounding board who understands commercial reality.

04

Fellow Investors

Investors interested in consortium opportunities, SEIS/EIS co-investment, or simply exchanging ideas with someone who approaches capital thoughtfully.
