He left his startup, Built $1M ARR in 10 months

Most people who reach the point Miquel reached do not walk away. He had co-founded a Spanish edtech company, dropped out of university to do it, scaled it to over 120 employees on VC funding, and had a clear path forward. But after three years, he made a decision that looked strange from the outside: he left to start over.

Not to rest. Not to consult. To build something new, smaller, and entirely on his own terms.

The result is Zernio, a social media API that lets developers build social integrations in minutes instead of months. It covers posting, analytics, direct messages, and advertising across 20+ platforms. And ten months in, it crossed $1 million in annual recurring revenue.

This is not a story about luck or timing. It is a story about a very specific set of decisions, made in a very specific order.

Most people assume anime & manga are Japanese industries. But for the first time in history, international revenue has surpassed Japan’s. TOKYOPOP’s been preparing for this moment for nearly 30 years. They have licensing contracts with giants like Nintendo and Disney, with stories told in 50 countries and 30+ languages. That’s translated to $15M in annual revenue. And it’s just beginning.

Miquel chose developers as his customer, and the reasoning was deliberate. He wanted to sell to himself. He already understood how developers think, what they need, and what frustrates them. He did not have to guess.

He also noticed something the market had overlooked: social media tools were built for end users and marketers, not for the engineers who had to actually implement the integrations. Nobody was solving the developer side. That gap was his entry point.

If you are figuring out what to build or sell, this is the most practical filter you can apply. Which problem do you know from the inside? That knowledge is faster, cheaper, and more durable than any market research.

Zernio's first version was built in a weekend. Not a polished, production-ready product. A working prototype that covered five social media platforms and proved the core concept. Getting the right API permissions took another month, with some approvals stretching to six months.

They did not wait for everything to be perfect before going live. They launched simple, then scaled the infrastructure as the product grew. Miquel is candid about this: he says if he were starting over, he would nail the infrastructure earlier. MongoDB became too slow and expensive at scale. Vercel hit limits they had not anticipated. They migrated pieces to Tinybird and Cloudflare queues, which cost time and effort they could have avoided.

The lesson is not to skip infrastructure planning entirely. It is that waiting for perfect conditions before shipping is usually more costly than shipping and adapting. They grew because they moved. The technical debt was manageable. The market opportunity, if ignored, would not have waited.

Zernio runs three tiers: Starter at $19/month, Accelerate at $49/month, and Unlimited at $999/month. The product is fully self-serve. No demos, no sales calls. Developers sign up on a free plan, explore on their own, and upgrade when they need more.

The pricing logic is built around progression. Users start low and grow into higher tiers as their needs expand. The $999 Unlimited plan targets SaaS companies with many end users who need unlimited social account connections. It is not the entry point. It is the destination.

If you are building a product, this model is worth studying. The free or low-cost tier is not charity. It is a conversion funnel. You lower the barrier to try, and let the product do the selling.

From day one, Zernio targeted bottom-of-funnel keywords for both SEO and paid ads. Phrases like "social media API" do not get millions of searches. But the people who do search for them are already looking for exactly what Zernio sells. The conversion rate on those searches is high precisely because the intent is clear.

This is a discipline most early builders skip. They chase traffic volume because bigger numbers feel better. But a thousand visitors who are mildly curious about social media convert far worse than fifty developers searching for a specific API solution.

They have since added YouTube videos, feature launch posts, and creator partnerships. But the foundation was always intent-driven acquisition. Start where the buyer is already looking, not where the audience is biggest.

Miquel calls building a team early his single best decision. In the indie-founder space, this is uncommon advice. Most solo builders treat hiring as something you do after you have validated everything. He treated it as a tool for validation itself.

The team is currently four developers and one marketer. One of those developers works exclusively on customer support. That sounds expensive for an early-stage product, but the return is direct: faster feedback loops, faster iteration, and customers who feel genuinely heard.

Great support at the early stage compounds. You learn faster, fix things faster, and retain customers who might have churned if their issue sat in a queue for a week.

You do not need to build the next Zernio. But there are three questions worth sitting with after reading this:

Which problem do you understand from the inside, not just from research? That is where your best product idea is likely hiding.

If you are running ads or writing content, are you targeting people with intent or people with curiosity? Intent converts. Curiosity mostly scrolls.

If you are building something self-serve, does your lowest-tier price create genuine value, or is it just a watered-down version people use to avoid paying?
