Follow-up: Mickey later scaled this same product from $40K MRR to $1M ARR and rebranded off getlate.dev to Zernio — see i-make-1m-year-selling-access-to-apis-i-dont-own for the $1M update (ads-from-day-zero, enterprise churn moat, building a team early).

TL;DR

Mickey, a Spanish founder, grew Late, a unified social media API, from $0 to $40,000 MRR in just seven months using only one marketing channel: Google Search. By combining organic search engine optimization (SEO) targeting bottom-of-the-funnel keywords with Google Search Ads, Mickey captured high-intent commercial traffic instead of attempting to build a viral social media following.

The Founder’s Story

Before launching Late, Mickey spent over five years launching and scaling startup projects in Spain. He co-founded an online education company called Academy, raising venture capital and scaling it to over 100 employees.

A year prior, Mickey decided to focus purely on B2B SaaS. He recognized a clear gap in the developer market: there were no developer-friendly, well-documented, and affordable APIs for social media automation. Most existing solutions were overpriced or lacked modern developer integrations. To fill this gap, Mickey built Late as an API-first social media scheduling engine and focused immediately on structured, intent-based distribution.

The Building Process

Late is a developer-focused, unified API that wraps around official social media platform endpoints (Facebook, Instagram, Twitter, LinkedIn). By purchasing maximum tier developer plans, Late provides developers with unlimited, frictionless access to all official features through a single, clean API integration.

Mickey built Late’s core application rapidly. He manages and updates his codebase using Cursor (Cloud Code) to code and iterate quickly.

Launch & Marketing Strategy: Google Search Domination

Mickey completely ignored short-form video (TikTok) and personal branding, focusing instead on capturing pre-existing commercial intent via a two-pronged Google Search playbook:

1. Organic Bottom-of-the-Funnel (BoFU) SEO:

Targeting High-Intent Commercial Keywords: Mickey used Ahrefs to target highly specific search terms with low keyword difficulty and modest monthly search volume (300 to 800 searches), such as “social media scheduling API” or “Twitter automation API.”
In-Depth Technical Guides: Mickey published 10 to 15 high-quality, long-form guides in the app’s first week to establish instant topical authority.
Manual Link Building: Mickey drove authority to his pages by manually reaching out to relevant blogs for backlink placements.
Result: Organic SEO generates over $8,000 MRR in highly profitable recurring revenue.

2. Google Search Ads (The Guaranteed Revenue Engine):

Keyword Matching: Mickey bids on the exact same bottom-of-the-funnel commercial keywords targeted by his organic SEO.
Custom Landing Pages: Every single ad group has a unique landing page specifically tailored to the user’s search query (e.g., custom pages for “Instagram API”).
Automated Bidding: Bidding parameters are set to optimize around a target Cost Per Acquisition (CPA) of $120 (their exact CAC target).
Value-First Ad Copy: Focusing on outcome-based copy rather than stating technical features (e.g., “Scale 30 days of social media in 1 hour”).
Result: Paid search generates $15,000 MRR with a $8,000/month ad spend (2.5x Return on Ad Spend).

Mickey’s 5-Step Google Acquisition Playbook:

Find Aligned Keywords: Map out commercial, high-intent keywords that align directly with your core product offering.
Push High-Quality Content Early: Publish 10 to 15 in-depth guides or free tools in week one to build SEO momentum.
Launch Search Ads: Target those same keywords, writing value-oriented copy and setting custom landing pages for each ad group.
Optimize and Double Down: Pauper low-performing keywords and scale high-ROI ad groups, testing copy and layouts via PostHog.
relentless CAC Benchmarking: Keep Customer Acquisition Cost (CAC) under 30% of the customer’s first-year revenue (or 20–40% of LTV).

Technology Stack

Coding IDE: Cursor (Cloud Code)
SEO Analysis: Ahrefs (“eightrefs”) ($200/month)
Analytics & AB Testing: Plausible (“data fast”) & PostHog
Advertising Platform: Google Ads ($8,000/month spend)

Paid Search Economics: Spends $8,000/month to generate $15,000 MRR (2.5x ROAS).
“Google search is not dead, but informational queries are dead… bottom-of-the-funnel commercial intent queries are still highly active and profitable.”
“Stop trying to be everything to everyone… picking one growth channel, getting really good at it, was 100 times better than being mediocre at 10 channels.”
