Before the agency, there were five years of things that did not work.

Marcos Ruiz lost tens of thousands day trading - including a single Brexit trade that wiped his account in one move. He made and then mostly lost a significant sum in crypto, walking away with around $10k. He tried an Amazon PPC agency. Trading bots. Ecommerce. None of it took.

He sat in a $1,700 a month studio in New York with about three months of runway and did something most people do not do after years of losses: he took an honest inventory of what he actually had.

What he found was a marketing degree, eleven years of being deeply embedded in Twitter, and firsthand experience working inside an info marketing business - watching how a personal brand converts attention into revenue. He had been building a rare skill set without recognizing it as one.

He started writing blog posts for $20 each on Upwork. Today, The Birdhouse - his personal branding agency - crossed $1.7M in revenue in 2025 and is currently operating at multiple six-figure monthly recurring revenue.

From Gigs to Agency

The climb from Upwork to agency was not a plan. It was a series of delivery moments that kept raising the stakes.

His first ghostwriting client paid around $1,000. The second came from a cold Twitter DM, also at $1,000 per month. A referral brought in $4k per month, and he delivered hard enough that the client asked to go to $8k. Then, one client's revenue scaled from $97k to $140k per month - driven by Twitter alone - while Marcos was still capturing only $8k of that.

That gap is where the model came from.

He hit his first $10k month three months after launch. Six months in, he was at $30k. The business was no longer a freelance operation - it was an agency that needed systems to run without him doing every piece of it himself.

Building the Product: Voice, Data, and Scale

The early product was Marcos and a Google Doc. Making it into an agency required solving two things: how to replicate someone's voice at scale, and how to know which content actually drives revenue.

The voice problem was the central objection. Every ghostwriting client says the same thing: no one can make it sound like me. His answer was a structured onboarding process - a 60 to 90 minute session designed to extract a client's stories, language patterns, worldview, and sentence rhythms. Combined with a creative brief and avatar breakdown, this became the foundation for every client relationship. It made the process teachable, and therefore scalable.

The data problem required patience. From the beginning, he tracked every piece of content the agency published - not just impressions, but whether it generated leads and sales. That database has compounded over time into tens of thousands of tracked content pieces across more than 100 niches. It is now the agency's closest thing to a competitive moat. AI can generate content. It cannot tell you which hook converted a cold audience into paying clients last month in a specific niche, because that data is proprietary.

The Business Model: Why They Get Paid on Results

The Birdhouse runs two departments with deliberately different structures.

  • The Info department works with founders and online educators on a monthly retainer plus revenue share. When a client collects cash from booked calls, the agency takes a share. When that cash grows, the share grows - without the fulfillment cost rising proportionally.

  • The Executive department works with founders and senior executives on flat retainers, building authority and audience without a revenue share component.

The revenue share model is the expansion engine. Traditional agencies have to raise prices or upsell to grow accounts. The Birdhouse's Info accounts expand automatically when results improve. When a client scales from $30k to $90k per month in collected revenue, the agency's earnings triple. Net revenue retention is built into the contract rather than requiring a separate sales conversation.

"If your work creates measurable revenue, price against the outcome, not the deliverable."

The Stack

The infrastructure centers on one principle: every client, channel, and dollar lives in a documented system - not in someone's head.

  • Airtable is the operating core. The team built Birdhouse OS on top of it: a custom system tracking every client, every channel's content, setter activity, cash collected, churn, and payroll. A separate Airtable base handles the sales CRM.

  • Make.com automates onboarding flows, Slack alerts, and a 90-day client feedback loop that sends forms automatically when accounts hit milestones.

  • Claude integrates into content workflows with custom skills the team built for hook generation, tweet writing, carousel headlines, and competitor analysis - all trained on their internal database.

  • Hypefury handles publishing. Canva and Figma manage design. Beehiiv powers the newsletter. Webflow hosts the site. Fathom records and summarizes every sales and client call.

  • They recently launched Birdhouse Labs - an internal AI team building proprietary tooling, including a client onboarding platform on Vercel and Supabase.

Year one ran on Google Docs and spreadsheets. That stopped working around client ten, when basic questions - like what content is actually driving revenue - required an hour of digging to answer. The move to Airtable with hard data definitions changed how decisions get made.

Growth: His Own Brand as the Demo

Most of the agency's growth has come from two sources: referrals, and Marcos's own content.

The referral dynamic is straightforward. Deliver a strong result in a niche, and the next two or three clients often come from that same network. The agency has now served more than 100 niches, which means there is almost always a relevant case study to lead with in any sales conversation.

The content side is more intentional. The Birdhouse is a personal branding agency, which means Marcos's own X and LinkedIn accounts function as a live product demonstration. He posts three times a day on X and daily on LinkedIn. By the time a prospect books a call, the content has already done most of the selling - prospects have read the threads, checked the engagement, and formed a view on whether the brand practices what it sells.

The highest-converting content format, by a clear margin: specific monetary results with timelines. A post stating that a client went from zero to $40k to $50k per month in 60 days outperforms any strategic or educational content. The buyers are founders who make decisions based on measurable outcomes, not concepts.

Four Things He Would Tell Someone Starting Out

  • Audit your unfair advantages before picking what to build. The skill most worth building on is usually something you have done so long you stopped counting it as a skill. Start there, not with whatever is currently trending.

  • Distribution matters more than product, and your own brand is the lowest-cost distribution channel available. An audience built while you have nothing to sell is the asset that makes every future launch cheaper and faster.

  • Concentrate before you diversify. The Birdhouse did not add Instagram until X, LinkedIn, and email were already systematized. Adding channels before mastering existing ones spreads attention without compounding results.

  • Track which content drives revenue, not engagement. A post with 50 likes that books two sales calls is worth more than a viral thread that books zero. That distinction only becomes visible if you measure cash against content from the beginning.

Where He Is Headed

The goal from here is scaling The Birdhouse to eight figures.

Marcos documents the process publicly. You can follow his thinking and see the work in practice on YouTube, where he publishes regularly on personal branding, agency operations, and building a business around your own content.

Picking your own 3PL feels smart. It's usually how you end up locked into the wrong one. There are 2,800+ out there, and the best fit is rarely the best pitch.
