Pen
What are we building?
Pen is a digital clinic that standardizes care, starting with hair loss treatment in Latin America.
Access to treatment today is fragmented — patients rely on inconsistent advice, slow processes, and unclear next steps. Pen creates a clear, structured path from evaluation to care.
Users complete a guided intake and receive a structured evaluation with clear next steps — including eligibility, risk level, and treatment options.
Pen is the first product built on Soficca, which builds the decision layer for healthcare.
We start with one highly protocolizable use case — and expand into adjacent conditions such as sexual health.

Hair loss care today is unclear, inconsistent, and hard to access.
Pen creates a clear path from evaluation to treatment.
Access is limited
There are few digital, private, and structured options available.
Most don’t know where to start
Treatment is often fragmented, slow, or based on inconsistent advice.
50%
of men experience significant hair loss by age 50.
In Latin America, millions of men experience hair loss — yet most don’t have access to clear, structured treatment.
Hair loss is common, but care is fragmented
A better way to treat hair loss — private, structured, and fully online
A better way to treat hair loss → private, structured, and fully online
100% online & discreet → no waiting rooms, no friction
Clinician-reviewed → safe, consistent, and scalable care

Your case is evaluated with a structured system and reviewed by licensed clinicians.
Treatment & ongoing care
Receive your treatment and track your progress over time.
Structured evaluation
Answer a guided intake and get a clear assessment of your condition.
From evaluation to treatment — clear, fast, and built for continuous care.
How it works
A structured path from intake to treatment, powered by Soficca

Guided intake
Users complete a structured intake covering symptoms, medical history, and relevant treatment context.
Decision system + clinical review
Soficca structures the case, evaluates eligibility and risk, and helps define the right next step for clinician review.
Treatment and follow-up
Users receive a structured treatment path, ongoing follow-up, and progress tracking over time.
More than an app — a system that improves over time
Pen is the patient-facing application through which Soficca delivers structured care.
Most health products solve a single moment. Pen is built to become more useful with every interaction — capturing structured patient context, decision history, treatments, and outcomes over time.
We start with one focused use case, then expand into adjacent conditions using the same decision logic, workflows, and longitudinal patient context.
That is how Pen grows into Soficca — the decision layer for healthcare.
A real decision output
Every case resolves into a structured, traceable decision report.
Illustrative example based on Soficca’s decision report structure.

How AI strengthens the system

Soficca combines structured clinical logic with AI-assisted data processing to make care more efficient, more consistent, and more personalized over time.
AI helps organize patient inputs, detect patterns, and improve follow-up — while clinical decisions remain structured, traceable, and clinician-reviewed.
As the system grows, Soficca uses longitudinal data to improve workflows, identify adherence risks, and support better recommendations across adjacent conditions.

Why Latin America
The category is proven in the US, but still fragmented across Latin America.
Pen starts in markets where men’s health demand is high, digital care remains underbuilt, and structured treatment pathways are still rare.
We begin with high-potential countries such as Mexico and Colombia, then expand into adjacent markets as the same decision system scales across the region.
High demand
Underbuilt category
Regional scalability
Hair loss and adjacent conditions are common, but care remains fragmented.
Hair loss and adjacent conditions are common, but care remains fragmented.
Most options are still generic, offline, or limited to a single condition.
How we go to market
Pen starts with a focused use case, a small number of high-potential markets, and a tightly controlled clinical workflow.
We begin by validating demand, messaging, retention, and operational quality around hair loss treatment. Instead of scaling broadly from day one, we use a structured rollout to learn what works with real users in real markets.
As those learnings compound, Pen expands into adjacent conditions through the same decision logic, care workflows, and longitudinal patient context.
Over time, what starts as a focused product becomes more than a clinic: the brand, data layer, and infrastructure grow stronger together — making Pen more effective as a product and Soficca more valuable as the decision layer behind it.


A business model designed to improve with scale
Pen begins with a focused subscription model built around treatment, follow-up, and continuity of care.
As retention improves, operations become more efficient, and adjacent conditions are added through the same infrastructure, the economics strengthen across the system.
Over time, higher retention, better sourcing, and more structured workflows make Pen more valuable as a product — and Soficca more defensible as the decision layer behind it.
Founder's perspective
Soficca © 2026
I believe the future of healthcare will belong to systems that make decisions clearer, care more continuous, and outcomes more measurable.
Pen is where that starts. Soficca is where it leads.
