Who We Are

We are a team of experienced, almost veteran, strategy consultants who have previously worked at the Big 4 and Big 3 consulting firms, large investment banks, hedge funds and private equity firms. We have helped more than 800 startups and small as well medium-sized firms develop comprehensive, robust, well-researched and realistic business plans for their business for the last 10 years. And in all those times we met all kinds of entrepreneurs. Highly motivated founders with a unique business idea but nothing more than that – no prior experience running a business, no financial skills, no marketing expertise. Just a light bulb moment and lots of energy! We have helped them get from the ideation stage to an investor’s stage! And then there are others who have a fully validated business concept, a prototype and some traction. All they need is a little guidance and lots of money.

There’s also a third category that we come across more than 40% of the time. People who know exactly what their business is, who their customers are, and what their 5-year business roadmap is. They simply need a business plan that lays it all perfectly in a professional manner that most banks, investors, PE firms and VCs prefer but either don’t have the time to do it or just do not know how to write it. No matter which category you fall into, we are here to help you.

An Initiative By ONS Business Consulting

ONS Business Consulting formed Stellar Business Plans as an initiative towards streamlining their business planning service. Due to the critical nature of this offering and the volumes of requests ONS receives, the team deemed it best to form an entirely separate and independent team focused solely towards writing business plans. This ensures our clients get the best and smoothest service possible.

Our Mission

Our mission is to provide unparalleled support to entrepreneurs and startups looking not just for consultants or contractors but partners who would give them the strategic direction they need at such an early stage of their business lifecycle. And we want to do this in the most cost-effective and efficient manner possible.

Our Promise

We want to transform the way business consultants work with clients. We can’t stress enough on the importance of having the right partners work alongside you from Day 1 if you really want your startup to be the next unicorn. Which is why we have formed not a team of writers and designers but investment bankers and corporate finance professionals who have worked in the midst of all the ‘action’ leverage from their extensive experience.
