When a Single Banker Can Move Markets—and a 200-Person Bank Can Do It with Half the Headcount
When we founded Finalis, we asked a radical question: what if the next elite investment bank wasn’t a skyscraper of analysts—but a lean, AI-enabled network of independent dealmakers working from anywhere?
That future is arriving faster than anyone imagined.
Thanks to breakthroughs in AI, cloud-native tools, and regulatory infrastructure, we’re entering the era of the “Investment Bank of One.” But here’s what’s important: the same infrastructure that enables a solo banker to thrive also supports growing, complex organizations. In fact, Finalis today powers investment banks ranging from one-person boutiques to firms with over 200 employees.
This isn’t about being small. It’s about scaling smarter.
From Institutions to Individuals—and Back to Institutions, Rebuilt
Across the knowledge economy, a structural inversion is underway: power is shifting from institutions to individuals.
Historically, top talent operated within large organizations. The investment bank was a classic pyramid—senior dealmakers atop a base of junior analysts, with layers of management in between. But that model was built for an era before cloud infrastructure and AI.
Today, that pyramid is collapsing. What’s emerging in its place is a new archetype: the Thin Company.
A Thin Company is lean in headcount but thick in leverage. Rather than scaling with humans, it scales through networks, automation, and intelligent infrastructure. Finalis members are living proof: some operate as one-person banks. Others run 30-, 50-, or 200-person firms—without the overhead and hierarchy of traditional shops.
This shift enables what we call the diamond org chart: fewer junior layers, a strong center of highly capable professionals amplified by AI, and modular teams that form around deals—not org charts.
Finalis isn’t just a tool for soloists. It’s a system for any banker or firm that wants to scale without scaling inefficiency. You bring the relationships and the insight—we handle compliance, infrastructure, and leverage.
In this new model, the individual doesn’t work for the institution.
The individual becomes the institution.
Finalis members are living proof: some operate as one-person banks. Learn more about how Finalis supports solo bankers.
Better Margins, Not Just More Headcount
Let’s zoom in on the economics. Traditional investment banks operate at relatively low gross margins. Based on public comps:
These numbers reflect labor-intensive structures and legacy tech debt. Most traditional firms scale by adding headcount, not leverage—leaving margin on the table. Most firms scale by hiring—adding humans to deliver more output. But with Finalis, firms scale by leveraging infrastructure.
Today, Finalis-affiliated firms—whether 1 person or 200—use the same tech stack, compliance engine, and AI-enabled deal tools. The result: materially better unit economics. We’ve seen firms maintain gross margins exceeding 70%, even as they grow revenue across geographies and sectors.
What Is a Thin Company—and Why Is It Winning?
A Thin Company is built to scale investment banking output—without the traditional headcount or overhead—by using automation, APIs, and platform leverage. Rather than staffing up, it taps into networks, automation, and flexible collaborators.
This model is being supercharged by AI tools that make one person 10x or 100x more productive.
- In tech, solo-founded startups now represent 35% of new ventures.
- AI-driven companies with under 50 employees are reaching $200M–$500M ARR.
- Tim Cortinovis, Sam Altman, and others have predicted the emergence of one-person unicorns.
The same playbook is coming to investment banking.
Breakaway Bankers: Precedent in Wealth Management
This trend mirrors the “breakaway advisor” wave in wealth management. Over the past decade, thousands of financial advisors left firms like Merrill Lynch and Morgan Stanley to go independent, enabled by platforms like Dynasty Financial Partners and LPL Financial.
According to one study:
- 100% of breakaway advisors on Dynasty’s platform reported being happier after going independent.
- 91% saw a net worth increase.
- All agreed they had greater equity upside.
These advisors didn’t go it alone – they plugged into support systems that gave them infrastructure without bureaucracy. Investment banking is now following that same path.
Channeling Your Inner Paul Taubman
Paul Taubman famously left Morgan Stanley to build PJT Partners from scratch—and now runs a multi-billion-dollar advisory powerhouse.
Here’s the thing: there are already multiple future Paul Taubmans already on the Finalis platform. Ex-bulge-bracket rainmakers building lean firms and scaling their franchises with none of the institutional drag.
Finalis doesn’t just enable the solo banker. We enable the next generation of elite banks—formed by individuals, powered by software, and scaled through networks.
Why Bulge Brackets Are Losing Talent
The bulge-bracket model is showing signs of strain, and experienced bankers are increasingly peeling off from firms using the model.
Here’s why:
- Overhead and Pay Cuts: Big banks siphon fees to fund costly operations, while independents keep 80%+ of what they earn.
- Bureaucracy: Committees, silos, and risk aversion stifle innovation.
- Lifestyle and Autonomy: The pandemic normalized remote work and non-linear careers, bankers want flexibility.
- Layoffs and Market Cycles: When mega-mergers slowed, even top producers got cut, and many chose not to return to big institutions.
Boutiques offer faster execution, greater freedom, and more persuasive economic incentives for those with strong client relationships.
The Platform Era: Enabling the Investment Bank of One
The missing piece for solo investment bankers has always been infrastructure, until Finalis came into the picture
Finalis is the full-stack OS for independent investment banks—combining regulatory compliance, AI-powered workflows, and a vetted dealmaker network.
We offer:
- Broker-Dealer Affiliation: Operate under our FINRA-registered umbrella without needing your own license.
- End-to-End Compliance: Licensing, record-keeping, filings, and supervision handled automatically.
- Tech Stack: Deal management, white-labeled CRM, data rooms, and workflow tools.
- Marketplace: A network of pre-vetted bankers to co-execute or refer deals.
- Partner Perks: Group negotiated rates for enterprise software, insurance, and data access (e.g. Preqin licenses).
- Revenue Sharing: Members earned an average of $127,500 per referred deal in 2024.
The result? A single banker can now replicate the back office, compliance infrastructure, and collaborative firepower of a legacy firm, with none of the overhead. Standing behind our platform is a team committed to restoring trust and transparency in capital markets—by empowering dealmakers, not replacing them.
Real Stories: Bankers Unbound
This isn’t theoretical.
- A former senior bulge bracket executive launched an advisory boutique under the Finalis platform.
- Finalis now supports 800 investment bankers across 370 firm—many of which operate as nimble 1-3 person teams closing multi-million dollar deals.
- The platform is facilitating multi-million-dollar M&A and capital raise deals, with teams forming and dissolving project by project, much like a film crew.
We’ve reached a tipping point: one-person investment banks are not edge cases, they’re edge leaders.
AI Is the Great Equalizer
Advancements in AI have made this possible, which allow for new efficiency gains in:
- Deal prep: GPT-4 writes pitch decks in minutes.
- Valuations: Automated models ingest data and produce outputs faster than analysts.
- Research: ML engines surface comps, buyers, and insights.
- Execution: Agents can handle diligence, project tracking, and outreach.
Major firms like JPMorgan report 40–60% time savings from AI copilots.
Finalis is seeing similar gains. We call the new model the Diamond Org Chart – not a pyramid of juniors, but a dense center of high-leverage generalists working alongside machines.
What used to require 10–20 people can now be done by just 2–3. Sometimes, even one person is enough.
Finalis: The OS for the $200 Million Banker
We believe the next generation of investment bankers won’t join firms, they’ll build them from the ground up. Finalis exists to power that shift.
We are:
- Democratizing investment banking infrastructure
- Ensuring full regulatory compliance for solo operators
- Enabling faster, more secure deal execution
- Delivering outsized productivity, via AI and cloud tools
Think of Finalis as the operating system for independent dealmakers. We’ve unbundled the 20th-century investment bank and reassembled it in software, so that the next generation of Wall Street doesn’t live on Wall Street at all.
The Future Is Modular, Not Monolithic
The “Investment Bank of One” isn’t a rebellion—it’s a revelation. A new way of working that unbundles Wall Street’s playbook and rebuilds it as software. But it’s not just for solos. It’s for any firm that wants to scale performance, not payroll.
This is the age of the $200M banker. And increasingly, the $2B boutique—powered by platforms, not politics.
As Sam Altman predicted, we’re entering an era of one-person billion-dollar companies. In investment banking, the same force is now in play—with AI, compliance, and platforms making it real.
