One-on-One Advising

Whether you’ve been in business a while or you’ve simply got an idea, sometimes you need answers. Maybe you need a game plan for bringing your idea to life. Or growing your business. Maybe you just need someone to make the hard parts easy.


DIY Business Plan Kit

A limited budget doesn’t have to mean a limited business plan. Distilling Your Dream is my step-by-step Business Plan Kit that shows you how to get it right using worksheets, templates and an ebook that explains it all — for any industry.


Custom Business Plans

My custom offering has it all: a business plan + one-on-one advising rolled into one. Together we’ll distill your idea into a growing business. You’ll walk away with a plan that attracts both investors and customers.

Ideas are great, but if customers aren’t buying, you’re sunk. I help my clients transform their ideas into a roadmap for building a growing business.

Getting it right from the start is often the difference between success and failure. I help you think through key issues before money and customers are on the line.

Startup founders want it all... with a cherry on top!
Attract Investors
Investors fund people, not ideas. The ability to clearly explain your concept and the reasoning behind it will make you stand out from the crowd.
From My Clients

“True to her firm’s name, Diane distilled my ideas into a highly effective business plan. She was equally adept at helping me develop my narrative and my financial projections. I’m really going to miss working with her.”

Dan Szor

Cotswolds Distillery

“Diane’s unique collaborative approach helped us build a stronger business. She had the experience to quickly recognize our core strengths, and consistently challenged us in an effort to improve our concept. Her guidance was a key reason we were able to secure investors.”

Rusty Sproat

Figo Pet Insurance

“Diane’s business plan secured us a $100,000 business loan within 48 hours. Our plan gave us credibility with our investors and enabled us to then secure $1 million. There is no question we couldn’t have done it without her.”
