Some other biggest clients of Bain & Company are:

Who Are Bain’s Biggest Clients Based On Size and Revenue?
Bain & Company is one of the Big 3 consulting companies alongside McKinsey and BCG. Its services are highly desired by some of the world’s biggest companies to help increase their revenue and efficiency.
With operations in over 40 countries, offering services across many different industries ranging from aerospace to agriculture, Bain’s list of services is focused on:
- Strategy
- Marketing
- Organization
- Technology
- Mergers & acquisitions
But these days, Bain also provides support with Human Resources and, of late, Diversity, Equity, and Inclusion initiatives. (Source)
Like other consulting firms, Bain is naturally very discreet about its clientele. Even on their website, the company uses fake names to protect its client confidentiality.
However, a company with such a big footprint leaves signs that analysts keep track of, and today, my research has found some of the biggest companies that rely on Bain’s service.
Here are 6 of Bain’s biggest clients ranked by their size according to the latest full-year stats:
1. Meta
Meta, or the company formerly known as Facebook, is one of the biggest companies in the world by market capitalization and revenue ($116 Billion in revenue). With almost 4 Billion monthly users, it is one of those giants with the most number of customers. (Source)
The tech giant’s current total assets sit at $206.69 Billion, with a market capitalization of $777.53 Billion. (Source)
The total number of employees working at Meta is around 86,482 men and women serving in different departments.
Lately, along with a host of other tech companies, Meta has had to downsize their operations and enact layoffs of many employees due to their gamble on the Metaverse not taking off.
Sources indicate that it was Bain & Company who advised Meta to shift the focus away from the Metaverse. As such, the company might have saved Meta from further losses. (Source)
2. Wells Fargo

3. Bayer AG
Bayer AG, a multinational German pharmaceutical and biotechnology corporation, is one of the major competitors in the global pharmaceuticals market. (Source)
The recent stats show that Bayer’s revenue is 50.739 Billion Euros, and this makes it another big client of Bain & Company. (Source).
The company’s market cap is 45.74 Billion Euros, with 125 Billion Euros in net assets and a workforce of over 100,000 professionals globally. (Source)
Bain offers these services to Bayer AG:

Its revenue has skyrocketed to a staggering $31.35 Billion ($20176 Billion market cap, almost 80,000 employees). (Source)
The COO of Salesforce, Brian Millham, expressed that a “change and reshape” of the company may be needed to drive efficiencies. “The structure of the organization — if we feel like it needs to change and reshape — we’re going to make those moves to drive the efficiencies.”
He also specifically mentioned that the company has hired Bain & Co., and it is reviewing its operations from now on (Making it yet another big client). (Source)
5. Baker Hughes
Another longtime and big client of Bain, Baker Hughes, uses tech to make energy safer and cleaner. It also provides products and services for:

It offers banking, commercial banking, investing, and other related services to its clientele with the help of its 35,000 dedicated employees. (Source)
However, in 2004, the financial services firm Charles Schwab was struggling, and the stock price had plummeted. But just four years later, Schwab had regained its position as an industry leader.
How did that happen?
Well, a key part of the turnaround was the introduction of Schwab’s Net Promoter system, which was created by Fred Reichheld, a Bain Fellow. (Source)
In this case, Bain’s services helped a huge banking conglomerate from bankruptcy.
As you can observe, the big guns choose Bain to be their consulting advisor for success. I have managed to find and list a few of them above. Hopefully, you now have some understanding of Bain’s own success and how it helps its clients to stay at the top of their game.
