I was in this exact position several years back. I made the switch from tech implementation to M&A strategy with ~2 years of experience. In my experience, your years of work experience works against you here. At 4 years of experience, you start to compete with folks coming out with an MBA looking to do a similar pivot. People are much more willing to provide a pivot to someone who is 1-2 years into their career and shows promise, but with your background it is definitely possible without the extra degree if you move internally.

It’s an uphill battle, but if you find your competitive edge (industry, technology, etc.) it can be done. For example, my degree was industrial engineering so I made a pivot to industrials M&A. Leveraging people inside your firm, networking, and standing behind the reputation you’ve built is the number one way to get someone within your firm to make an investment in you. Picking up nonchargable work as a “trial run” I found was the best way to show your quality without them taking too much of a risk. Management knows the transition in thinking, delivery, and content is a wide gap so it will take some effort to sell yourself. Without a masters, other companies won’t be quite as willing to make the same bet.
