A founder-focused ghostwriting agency turns client expertise into Twitter content and recurring retainers.
now about $70K/month at ~60% margins (founder-reported)
"If I just make somebody more money than they pay me, then I'll have a client forever" — Birdhouse sells Twitter as a monetization channel, not a follower count.

Birdhouse is a Twitter ghostwriting agency led by Marcos. It writes tweets and threads, repurposes client videos and podcasts, and adapts formats such as articles, replies, and live Spaces to each client’s niche. Marcos focused on coaches, consultants, and education companies because those businesses can monetize attention quickly. He started with Upwork projects, then used early work as proof in direct messages. After landing a $1,000 monthly client, he gathered a testimonial about seven free-trial subscribers and used it to approach software founders. A $3,000 monthly coaching client became a turning point: weekly viral content drove sales, creating a strong renewal case and referrals. Marcos says Birdhouse grew from zero to $65,000 per month in one year and now runs at about $70,000 a month with margins around 60%, delivered by two senior writers, one junior writer, an ops manager and a sales rep. He also describes sending 100–200 cold DMs daily, publishing two or three tweets a day, and building inbound and warm outreach alongside cold prospecting. He positions the offer as monetization, not follower growth, which is why retention holds.
For a Twitter ghostwriting service aimed at coaches and software founders, start where buyers already look for freelance help. Marcos found his first clients on Upwork, which gave him paid work and a platform to earn a review before asking strangers to trust a new agency.

Data credibility: Founder Marcos states the $65K/month-in-one-year figure, the current ~$70K/month, ~60% margins, team size and early client prices himself in a Starter Story interview. All figures are self-reported and unaudited; the $20K–$30K a client made from one thread is his own estimate.
Marcos says his first clients came through Upwork, and he later describes landing a $1,000-per-month client after a few weeks of outreach.
Birdhouse’s loop connects client results, proof, and better-qualified leads. Marcos said a $3,000-per-month coaching client began getting viral content each week, and the posts drove sales.
A new ghostwriting agency can spend weeks sending messages before a prospect responds. Birdhouse’s story points to a way through that quiet period: keep prospecting measurable, improve the offer from real conversations, and deliver enough work to create proof.
