Correcto’s mission is bold: empower millions to write better Spanish, with AI that feels natural, smart, and seamless. After raising a $7M seed round and gaining global recognition, the team faced a familiar SaaS challenge: turning downloads into real product usage.

Downloads were growing. Activation wasn’t.

That’s when Correcto shifted its growth focus — from acquisition to activation — and made a strategic bet: insights from Amplitude wouldn’t just track user behavior; they’d help change it.

✅ Result: A 208% increase in activation, stronger retention, and a sharper understanding of their ideal user.

The Challenge: From Interest to Interaction

Correcto started with strong momentum: thousands of Chrome extension downloads, top-tier press coverage, and promising early adoption signals. But as they tracked key metrics, one thing became clear:

Most users were installing the extension — but not engaging with its core value: writing suggestions powered by AI.

It wasn’t a growth problem. It was an activation gap.

Mapping the Activation Funnel with Amplitude

Using Amplitude (via a startup scholarship), the team mapped the full user journey — from install to the first meaningful product action. That meant redefining what “activation” truly looked like.

For Correcto, that metric became:

Activation = a user installing the extension + interacting with at least one grammar suggestion

With this defined, the funnel was rebuilt and segmented. The data exposed a key drop-off: most users completed the install but never triggered a suggestion.

This clarity changed everything.

Experimenting with Onboarding: Friction Down, Value Up

Instead of guessing why users dropped off, Correcto redesigned its onboarding — guided by data and experimentation.

Using feature flags and cohort testing, they optimized:

🎯 Onboarding flow: Fewer steps, more context, and earlier value delivery
✍️ Visual cues: A magic wand icon was replaced with a pen and spark — resulting in higher engagement
✅ Micro-interactions: CTAs were simplified, and nudges aligned with user intent

Every change aimed to answer one question: How can we get users to their first successful interaction faster?

The answer worked. Between July 2024 and March 2025, activation rates jumped from 17.4% to 53.5% — a 208% increase.

Sharpening the ICP: From Broad Reach to Real Fit

Once activation improved, the team took the next step: understanding who activated — and why.

Amplitude’s cohort analysis revealed a high-performing user segment:

Age: 18–24 years old
Location: Colombia
Source: Search campaigns

This group had higher activation, better retention, and stronger product engagement than any other.

So the team doubled down:

Rewriting copy to match their tone and language
Prioritizing organic and paid search channels
Improving CAC:LTV by focusing on users with real retention potential

A New Growth Model: Retention Over Vanity

Correcto’s early traction was driven by downloads, Chrome reviews, and social proof. But those were surface-level metrics.

To build sustainable growth, they shifted to:

📈 Product usage
🔄 Feature interaction
🔒 30-day retention
🔍 Behavioral analysis over assumption

With Amplitude as the single source of truth, all teams — engineering, product, and marketing — began speaking the same language: impact.

🚀 Key results:

Activation: 53.5%
30-day retention: 64.3%
New cultural habit: asking better questions, testing with intention

Key Takeaways for Product-Led SaaS Growth

Correcto didn’t scale through hacks. They scaled by changing their mindset.

✅ From marketing to product
✅ From acquisition to activation
✅ From tracking behavior to influencing it

This case study proves that with the right tools, the right user insights, and a clear activation metric, product teams can build growth loops that last.
