ONS Business Consulting

About Us

A dynamic strategy consultancy providing expert solutions to complex situations

ONS was formed in 2012 as a boutique strategy consulting firm helping companies with their M&A, financial planning, and business development projects. Incorporated by expert finance professionals who previously worked at big corps like Deloitte, McKinsey, JPMorgan, Citi, etc, ONS’s aim was to deliver projects of the highest quality and intellect keeping in mind our client’s objectives.

What’s unique about us is our ability to envision each project as our own and deliver accordingly. We believe content is king. And thus, we make sure all our deliverables are written in the most compelling manner whether it is a sales presentation or buy/sell-side pitchbook.

In 2015, we expanded our offerings to help budding and innovative entrepreneurs build and pivot their startup ventures. We do this by providing assistance with their business plan and strategy, building a feasible business model, conducting in-depth research of the target market, and finding the right investment for their company. To date, we have worked with more than 400 startups and helped many of them raise $580mn in investment so far. These include companies from various different industries including financial services, technology, real estate, fashion, aviation, music, F&B, energy, and many more.


We were 4 when we started our journey and have reached a team size of 13 with two office locations – London and New York – two of the world’s fastest-growing cities. Our focus is geared towards maximum client satisfaction and that is something we strive and have managed to achieve with great success so far.

We understand how time consuming and utterly daunting some tasks can be. Like an analyst trying to prepare a winning pitchbook with tight deadlines and 100 other things to do, a CEO of a one-man company struggling to write a comprehensive business plan while simultaneously running a business or a company looking to get expert opinion on their business’s valuation. And that’s where we come in.

As M&A experts we help our clients build pre and post-merger valuation models, conduct financial due diligence and help identify potential acquisition targets. Some of us in the team have been entrepreneurs ourselves having had successful exits and can leverage our experience in order to help startups build pitch decks that leave a lasting impact on their investors.
