The Thesis: From Running an Agency to Owning a Portfolio

Peter Kang ran his agency's finances on an Excel spreadsheet for fifteen years. Custom macros, manual data entry, a file built by a friend from his Lehman Brothers days. When he and co-founder Sei-Wook Kim finally outgrew it, they didn't just upgrade their accounting software. They upgraded their entire business model — from running one agency to acquiring a portfolio of them. Barrel Holdings now operates six specialized agency businesses, employs over 150 people across 200+ active clients, and recently published a book codifying the playbook. The Excel file is gone. The compounding has just started.

Kang and Kim met at Columbia in 2003. Three years later, they founded Barrel — a generalist web design shop in New York. For the first fifteen years, Barrel operated like most small agencies: linearly, tied directly to the founders' labor and relationships, revenue bouncing between good years and flat ones. Every dollar earned required another hour sold. The founders owned a business, technically, but what they really owned was a job.

The first holdco move isn't buying a company. It's installing a CEO in your own company.

This is the compression point. Barrel was doing competent execution work, generating revenue, but building no structural advantage. What changed wasn't the quality of the work — it was the architecture of the business. The transition from "agency founder" to "portfolio operator" didn't start with an acquisition. It started with Kang learning to step away from the work he'd done for two decades.

Timeline

Era 1: Execution — One Agency (2006–2020)
2003Kang and Kim meet at Columbia University.
2006Applied Structure #1 Barrel founded as a generalist web design and development shop in NYC. Neither founder has agency experience. Kang's only corporate reference: a year at Lehman Brothers before it ceased to exist.
2006–2015Gradual growth. Mile wide, inch deep — consumer brands, B2B tech, financial services, home services. Kang runs finances on a custom Excel spreadsheet for 15 years.
2016–2020Applied Structure #1 Barrel narrows to Shopify Plus for CPG brands. Specialization enables value-based pricing and advisory positioning. Clients engage Barrel for strategic guidance, not just builds.
Aug 2020Applied Structure #12 Kang starts Agency Journey blog — monthly public documentation of the business. No content strategy, no funnel design. Just a discipline of writing what's happening.
Era 2: Ownership — Building the Portfolio (2021–2024)
2021Applied Structure #9 Barrel Holdings formed. Vaulted Oak launched as first portfolio company — a Shopify/WordPress maintenance agency with longtime employee Jason Fan as co-founder and operator. The holdco structure is born.
2022Applied Structure #18 BX Studio launched — a Webflow agency. Hits 100% YoY growth by 2025. Wins Webflow Enterprise Agency of the Year. Q3 2022 marks first profitable quarter for all portfolio companies simultaneously.
2023Bolster co-founded — a branding/Framer agency with Henry Alcock-White. Early traction: 219% revenue growth in 2024. (Later shut down in 2025 when market didn't support it.)
2024Applied Structure #4 Kang and Kim step away from Barrel's day-to-day entirely. Lucas Ballasy — who joined as a junior designer nearly a decade prior — takes over as CEO. This is the holdco working as designed: operators run businesses, founders allocate capital.
Era 3: Capital Formation — Acquisitions (2025–ongoing)
2024Applied Structure #10 Prima Mode added — a health & beauty Amazon agency. Portfolio now spans Shopify, Webflow, WordPress, and Amazon.
Mid 2025Applied Structure #9 AO2 Management acquired — first major external acquisition. Full-service Amazon agency. Founder Nathan Neeley transitions out; Jessica Wright promoted to CEO. Portfolio crosses 150 employees, 200+ clients.
Oct 2025Bolster shut down. Framer agency market didn't achieve sustainable traction. Kang writes about it publicly. Not every bet works.
Late 2025The Holdco Guide published on Amazon. 150+ copies in weeks — modest by publishing standards, strategic by deal-flow standards. Every reader is a potential seller. Exploring Reg D fundraise for future acquisitions — first consideration of external capital.

Holding Company: Separating Ownership from Operation

The architectural decision wasn't acquiring agencies — it was separating ownership from operation. Barrel Holdings owns the portfolio; individual agency leaders run their businesses with autonomy. Kang and Kim retained equity at the holding company level while creating equity incentives for portfolio company leaders.

The holdco provides centralized finance, legal, HR, and sales/marketing support — what Kang calls an "operating ecosystem." For a $2–4M agency founder drowning in admin, this is material. The holdco becomes the buyer of choice not because it pays more, but because it offers relief from the operational burdens that made the founder want to sell.

The 2024 numbers tell the diversification story. Barrel — the flagship — dropped 23% from client churn. In a single-agency model, that's a crisis. In a holding company, BX Studio's 72% growth and Bolster's 219% growth offset the damage. Holdco EBIT still grew 47%. The portfolio absorbed a hit that would have devastated a standalone agency.

Creator-as-Platform: Content as M&A Pipeline

Most holding companies hire investment bankers to source deals. Kang writes blog posts.

Over 65 episodes and five years, Agency Journey became a trust engine. Kang writes with uncommon transparency — sharing revenue figures, margin compression, strategic pivots, failed agencies, even personal finance snapshots. The series attracts agency founders who see themselves in his journey, feeding three critical pipelines: M&A deal flow (sellers approach him), talent recruitment (leaders want to work with him), and industry positioning (he's seen as a peer, not a buyer).

We're still amazed that we 'get to' do this as our full-time job.

Alongside the blog, Kang and Kim launched AgencyHabits — templates, proposals, pricing frameworks, and operational playbooks drawn from the portfolio. Not gated behind a $10K mastermind. Open, practical, and functioning as both marketing and genuine industry contribution.

The content assets don't generate significant direct revenue. They generate deal flow, trust, and positioning — which is more valuable. Newsletter subscribers organically become M&A leads. Every reader of The Holdco Guide is a potential seller, partner, or collaborator. Kang now runs paid ads targeting agency founders against his most strategic posts.

The Compounding Effect

Barrel Holdings Value Flywheel
BARRELHOLDINGSAgency Journey BlogSTRUCTURE #12M&A Deal FlowSELLERS APPROACHPortfolio GrowsSTRUCTURE #9Cash Flow Funds NextSELF-FUNDEDOperating EcosystemSHARED SERVICESMore Content / ProofRESULTS → STORIES

Each rotation strengthens the next. Kang writes transparently about the portfolio (Agency Journey). Transparency attracts sellers who trust him over faceless acquirers (deal flow). Acquisitions grow the portfolio (Holding Company #9). Portfolio cash flow funds the next acquisition without outside capital. Each new agency adds operational lessons and shared services capacity (operating ecosystem). Better results produce better stories to write about. The cycle accelerates.

The Holding Company (#9) is the architecture. Creator-as-Platform (#12) is the deal-flow engine. Diversified Revenue (#10) is the risk mitigation — when Barrel dropped 23% in 2024, the portfolio absorbed it. Premium Service (#1) in each specialized agency ensures margins high enough to fund the whole system from cash flow.

Transferable Lessons

01Specialize the First Business Before Building the Second

Barrel spent 15 years narrowing from generalist to CPG/Shopify before Kang and Kim tried building a portfolio. The first business had to work — operationally, financially, reputationally — before the holding company could layer on top. Most agency founders who try to "go holdco" skip this step.

The pattern: Master one business completely. Then build the structure that lets you own multiple businesses. The order matters.

02The First Holdco Move Is Hiring Your Replacement

The decisive move wasn't acquiring agencies — it was stepping away from Barrel's day-to-day in 2024 and installing Lucas Ballasy as CEO. This is the test of a real holding company vs. a founder who owns multiple businesses. The structure has to function without the founders in the operating seat.

The question: Can your business run without you? If not, you don't own a company — you own a job. The holdco model starts when the answer becomes yes.

03Content Transparency Beats Investment Bankers for Deal Flow

Kang's five years of monthly writing — sharing revenue numbers, margin compression, failed experiments — builds trust with agency founders who might sell. When a $2M agency owner reads five years of Agency Journey, they're not meeting a faceless acquirer. They're meeting someone who's lived their exact problems.

The application: Whatever your M&A or partnership pipeline needs, consider whether radical transparency about your own business could be the most effective top-of-funnel. People work with people they trust. Trust compounds with consistency.

04Have the Discipline to Shut Things Down

Bolster, the Framer agency co-founded in 2023, was shut down in late 2025. Kang wrote about it publicly. Starting an agency from scratch proved harder and less predictable than acquiring one with existing clients and revenue — a lesson that influenced their shift toward acquisitions.

The signal: Willingness to close a portfolio company after two years signals operational seriousness, not failure. Most holding company narratives become hagiography. The honest ones include the shutdowns.

05Cash Flow Is Capital

Barrel Holdings operates without outside capital as of early 2026, funded entirely by portfolio cash flows. They target agencies with $800K–$1.5M in EBITDA — businesses that are cash-flow positive from day one. This isn't the PE playbook of leverage and flip. It's the patient capital playbook of compounding.

The principle: You don't need institutional capital to acquire businesses. You need a first business that generates more cash than it consumes. The surplus is your acquisition fund.

06What Wouldn't Transfer

The 18-year runway. Kang and Kim bootstrapped Barrel for 15 years before forming the holding company. Co-founder stability — 20+ years of partnership with complementary skills is rare structural capital. NYC client ecosystem — proximity to CPG brand headquarters created deal-flow density most markets don't offer. The writing discipline — 65 monthly posts requires a genuine habit most operators find uncomfortable.

The honest caveat: They also flirted with the PE-backed rollup playbook — SBA 7a loans, buy with 10% down, scale fast, flip. Kang pulled back after realizing it didn't fit their values. The recalibration toward long-term cash flow over quick exits was a meaningful pivot, not the original plan.
