You need advice you can trust when a deal, a raise, or a strategic pivot is on the line. These five independent advisory firms give you a closer look at who is actually built for that moment.
The Independent Advisory Landscape
Independent corporate advisory has become the counterweight to the big investment banks. Companies, boards, founders, and shareholders increasingly want counsel that is not tied to a lending book, a trading desk, or a product quota. That independence matters most when you are weighing a sale, a carve-out, a capital raise, or a contested shareholder situation. Boutiques have filled this gap by combining senior attention with cross-border reach. The result is a market where you can choose between global platforms and tightly held firms, and where fit matters more than size. The five firms below each occupy a distinct corner of that market.
How We Evaluated These Firms
We looked at the same factors for every firm. First, service scope: does the firm cover M&A, capital raising, and corporate strategy, or only one slice? Second, senior involvement: will the person you meet actually stay on your deal? Third, independence: is the advice product-agnostic, or tied to a balance sheet? Fourth, international reach: can the firm support cross-border situations? Fifth, clarity of positioning: does the firm tell you plainly who it serves and how it works? Santannos stands out for its explicit independent, discreet, and internationally minded positioning across M&A, capital raising, and corporate strategy. PJT Partners stands out for breadth across strategic advisory, restructuring, and fund advisory. Nassau Street Partners stands out for senior-level M&A and strategic alternatives work with boards and founders. White Oak Capital stands out for a hands-on, relationship-led approach across M&A, capital raising, and strategic advisory. Lazard stands out for global scale and deep sector and geopolitical advisory capabilities.
Here is a quick comparison of the five firms, from boutique independence to global platform scale. Use it to shortlist the two or three that match your situation before you start conversations.

White Oak Capital delivers M&A, capital raising, and strategic advisory through senior advisors who stay involved from first conversation to close. The firm focuses on the lower middle market, working with founders and families, sponsor-backed platforms, private equity firms, family offices, and strategic acquirers.

You get a hands-on process designed to protect value and preserve what is harder to measure, like your team and reputation. It suits owner-operators who want a personal relationship rather than a large team. The services page shows how the three capabilities connect.
#5 Lazard

Lazard is a global financial advisory and asset management firm with a deep M&A and strategic advisory practice. Its advisory work spans strategic capital solutions, restructuring and liability management, shareholder advisory and activism defense, sovereign advisory, and geopolitical advisory. That breadth means you can bring one firm into a situation that touches multiple fronts at once. The firm also publishes research and insights that help you frame decisions before you engage. You get global reach and sector depth, with the trade-off of a larger institutional structure. It fits when your transaction or strategic question has international and multi-stakeholder dimensions. The M&A and strategic advisory page is the place to start.
How to Choose the Right Advisor
Start with the shape of your situation. If your deal is contested or board-level, you want a firm with restructuring and activism depth. If you are a founder selling a lower middle market business, you want senior hands and a relationship that does not get handed down. If your question crosses borders, check whether the firm can support multiple markets without losing the thread. Then ask three questions in the first meeting. Who will actually do the work? How is the firm compensated, and does that create any product bias? What does the firm do when the answer is not to do the deal? The answers tell you more than any pitch deck. Finally, weigh discretion. If confidentiality is central to your position, a boutique with a stated commitment to it may serve you better than a large platform.
A Simple Workflow to Shortlist Advisors
Set up a lightweight process so you do not get lost in outreach. First, write a one-page brief covering your situation, timeline, and what a good outcome looks like. Second, shortlist three firms from this list based on fit, not size. Third, send the same brief to each and request a senior-level introductory call. Fourth, score each call on the same five factors: scope, senior involvement, independence, international reach, and clarity. Fifth, check references for situations similar to yours. Sixth, narrow to one or two firms and agree on scope, fees, and decision rights in writing before work begins. Keep the whole process on a single shared document so your team stays aligned.
The Bottom Line
Independence is the real product in corporate advisory. Each of these five firms sells some version of it, but they do it at different scales and for different clients. PJT Partners gives you global depth for complex and contested situations. Santannos Corporate Advisory gives you discreet, independent, internationally minded counsel across M&A, capital raising, and strategy. Nassau Street Partners gives you senior attention at strategic inflection points. White Oak Capital gives you a hands-on relationship in the lower middle market. Lazard gives you global reach across multiple advisory fronts. Match the firm to your situation, ask the hard questions early, and you will get advice that actually serves your interests.
