The Broker-Dealer for Boutique Investment Banks
Finalis provides the FINRA-registered broker-dealer infrastructure, outsourced compliance support, and deal platform that boutique investment banks need to run a compliant practice. You maintain your brand and deal sourcing; we handle the infrastructure.
What Boutique Investment Banks Actually Need From a Broker-Dealer
Most boutique firms find the better path is affiliation and outsourced compliance.
Affiliating with a FINRA-registered broker-dealer gives your practice the regulatory infrastructure it requires. Without forming a separate entity, maintaining net capital, or hiring a compliance staff you have to manage.
Finalis was built for independent investment banking deal practices.
Broker-Dealer Infrastructure Purpose-Built for Deal Professionals
“The broader Finalis community is powerful. Finalis has basically created a collaboration space for individual firms, which gives us the collective power and resources of a much larger institution.”
A Network Built for Deal Volume
With 900+ affiliated members across M&A, capital raising, private placements, and sector-specific advisory practices, the Finalis network brings together active independent deal professionals working through a single broker-dealer platform.
That matters when you need co-advisors, referral relationships, or syndication partners on a live transaction.
In 2025, Finalis members closed $122M* in total success fees across M&A and private placement transactions. These are active deal professionals running live mandates, which means real co-advisory and referral capacity exists across the network.
*Calculated July 29, 2026. Gross success fees are earned by Finalis Members for deals closed on the Finalis Platform in the defined period (without subtracting FINRA/SIPC and Finalis fees).
Frequently asked questions
What is broker-dealer affiliation for a boutique investment bank?
+
Broker-dealer affiliation is an arrangement where a boutique investment bank or its principals register as representatives under an existing FINRA-registered broker-dealer, rather than forming and operating their own. The affiliated broker-dealer provides the regulatory infrastructure, including FINRA registration, compliance oversight, and supervisory procedures, while the boutique firm runs its practice independently.
Why do boutique investment banks affiliate with a broker-dealer instead of forming their own?
+
Operating an independent broker-dealer requires FINRA membership, a full compliance function, a chief compliance officer, net capital maintenance, and ongoing regulatory filings. For a deal-focused boutique, that overhead competes directly with time spent sourcing and executing transactions. Affiliation gives a boutique firm access to that regulatory infrastructure, managed by a team that handles it full time.
What does Finalis provide to boutique investment banks?
+
Finalis provides FINRA-registered broker-dealer backing, Series 79 and Series 82 exam sponsorship, a structured deal compliance workflow, engagement letter review using AI-assisted tools that flag issues before they reach compliance, AML and KYC support, an integrated virtual data room, and access to a network of 900+ affiliated deal professionals. These are built into a single platform designed around the investment banking deal lifecycle.
How does deal compliance work for boutique investment banks affiliated with Finalis?
+
When a deal is submitted through the Finalis platform, it enters a structured compliance workflow. Engagement letters are reviewed using AI-assisted tools that flag issues before they reach compliance, catching common errors at the draft stage. Compliance reviews the transaction for applicable FINRA requirements, and clearance is provided before the deal proceeds. Documentation is handled within the platform, creating the books and records trail required under FINRA rules as the deal moves forward.
Can a boutique investment bank keep its own brand when affiliating with Finalis?
+
Yes. Affiliating with Finalis means registering as representatives under Finalis Securities for regulatory purposes. Your firm's name, brand identity, market positioning, and client relationships remain entirely yours. Finalis provides the regulatory infrastructure your practice operates within.
What FINRA exams do boutique investment banking professionals need?
+
Investment bankers advising on M&A transactions typically need the Series 79. Professionals conducting private placements typically need the Series 82, though a Series 7 may be required depending on transaction type and scope. Finalis sponsors registration for affiliated members across these examinations and provides support through the process.
How does Finalis support cross-border transactions for boutique investment banks?
+
Foreign investment firms and U.S.-based boutique banks working on cross-border transactions can access U.S. investors through SEC Rule 15a-6 chaperoning. Finalis provides chaperoning services for compliant engagement with U.S. investors.
How is affiliating with Finalis different from building an in-house compliance function?
+
Building an in-house compliance function means hiring a CCO, establishing written supervisory procedures, maintaining net capital, and managing ongoing FINRA filings and regulatory examinations. For most boutique investment banks, that overhead is disproportionate to the practice size. Finalis affiliation provides access to a built compliance infrastructure. A dedicated team manages the regulatory requirements, which lets your principals focus on deals.
