Why We Exist

Assembling a deal team for smaller transactions shouldn't be this hard

When you’re buying or selling an SMB or lower middle market business, the stakes are real — but finding the right service providers is still fragmented. Buyers and sellers often rely on referrals, cold outreach, or generalist marketplaces or directories to find attorneys, diligence firms, tax advisors, and other specialists.

One marketplace. Vetted providers. Built for your deal size.

DueDilio replaces that fragmented search with a curated network of M&A service providers vetted for relevant deal experience, credentials, and client references.

Submit once, receive multiple proposals from qualified providers matched to your project

Coverage across the deal lifecycle from buy-side and due diligence through sell-side and post-acquisition support.  

$149 one-time lifetime access with no subscription or per-project platform fees

Our clients include searchers, independent sponsors, PE firms, family offices, business owners, and intermediaries working on SMB and lower middle market transactions.

What We Believe

The principles behind the platform

Every decision we make — from how we vet providers to how we price access — traces back to a few core beliefs.

Curation over volume

We don’t accept every provider who applies. A smaller, carefully vetted network is more useful than an open directory where anyone can list themselves.

Smaller deals deserve real infrastructure

SMB and lower middle market transactions carry real complexity, but participants often have fewer resources. They deserve a professional marketplace built for their deal size.

Transparency builds trust

Our pricing is simple and upfront: $149 for lifetime client access, with no subscription or per-project platform fees. Clear expectations matter when real transactions are on the line.

We're a people business

M&A is personal, even when the platform is self-service. Every project involves real money, risk, and consequences, so the marketplace is designed around trust, fit, and accountability.

Founder

Roman S. Beylin

Founder

I spent more than a decade in finance, including equity research at Fidelity Investments and institutional equity sales at CLSA Americas, before moving into entrepreneurship. After co-founding and exiting an alternative data business, publishing The Business Inquirer, and buying and selling several small businesses myself, I kept running into the same problem: finding qualified M&A service providers for smaller transactions was unnecessarily difficult. I founded DueDilio in 2021 to solve that problem.

Today, I’m based in Miami and continue to build DueDilio around the needs of SMB and lower middle market buyers, sellers, and intermediaries.

What Clients Say

Trusted by dealmakers across the market

“My firm engaged DueDilio for an accounting review of our portfolio company financials. We were quickly provided with a few candidate firms who provided proposals — all of which were well qualified. Our experience was very positive.”

Richard G.
Boutique Private Equity Firm

“DueDilio was tremendously helpful in sourcing a financial diligence and legal advisor for a small acquisition. They sent quotes promptly, with a wide range of service providers, and also provided helpful big-picture advice on how to find the right fit. I strongly recommend DueDilio — I met providers I wouldn’t have found otherwise, and they were great fits for my deal.”

“DueDilio made finding a business advisor easy for me and saved me a ton of time. I was presented multiple proposals within 24 hours and was able to select an experienced advisor I would not have found otherwise.”
