About Xoul
"We built Xoul because we couldn't find a baby app that assumed two parents existed."
Founded 2024, Austin TX. Bootstrapped. Two founders who were awake at 3am and had the same problem.
Alejandro Taubas
CEO & Co-Founder
My daughter was born in late 2023. Six days in, the paper notebook by the crib — the one we'd been told to keep — was illegible. I couldn't read my own 2am handwriting. My partner's 4am entries were abbreviated in ways neither of us could decode the next morning. The iMessage thread we'd started to coordinate overnight shifts had 200 messages in it and the feed log was somewhere in the middle.
I'm a software engineer. I've been building mobile and web software for over a decade. I spent three nights trying apps from the App Store and couldn't find one that assumed two people lived in the same house. Every app was built for a single caregiver logging on behalf of the family. That's not how our nights worked.
I built v1 over a weekend in early 2024 — a shared timeline, timestamps, volume fields, caregiver attribution. My partner used it the same night. The iMessage thread went quiet. I showed it to Maya, who'd been thinking about the same problem from a product design angle and had been through the same 3am coordination breakdown with her first kid. She improved the hand-off view significantly. We decided to build it properly.
We incorporated in early 2024. Launched v1.0 in March 2025. We're two people, bootstrapped, working out of a co-working space in South Austin about two miles from where my daughter was born. That proximity is intentional.
The team
Two founders, one shared problem
Maya Chen
CTO & Co-Founder
Maya leads engineering and product architecture. She came to Xoul from a background in consumer mobile, with prior time building data-minimization tools for small health-adjacent teams. When Alejandro showed her the v1 prototype, she had one note: the hand-off summary was too dense. She redesigned it from scratch. Her first kid went through the 4-month sleep regression while they were building the sleep window feature — which is why that part of the product is more honest than most.
"We didn't want to build a data monetization engine. We wanted to build a household tool. The subscription model is how we stay honest about that."
— Alejandro Taubas, CEO & Co-Founder
Honesty
What Xoul is not
We think being explicit about limitations builds more trust than overpromising. Here's what Xoul isn't — and why that matters.
Not a medical device
Xoul does not diagnose, screen, or treat. Nothing in this app replaces a conversation with your pediatrician.
Not a sleep coach
Xoul shows you estimated sleep windows based on logged patterns. It does not prescribe sleep training methods or tell you to let your baby cry it out.
Not a single-parent default
Xoul is built for households with 2+ caregivers sharing logs. That's the design wedge — not a statement about family structure.
Not a milestone tracker
Xoul's core is routine logging (sleep, feed, diaper, flags). It is not a developmental milestone checklist or well-baby chart.
Not HIPAA-covered
Xoul is a personal organizer for your household. We design with data minimization in mind, but we are not a covered entity under HIPAA.
Austin, TX roots
Xoul is a two-person team based in Austin, Texas. We work out of a small co-working space in South Austin, about two miles from where Alejandro's daughter was born. The proximity is intentional — we want to stay close to the households we're building for.
We are bootstrapped. We have not raised outside capital, and we're not planning to in the near term. At $5.99/month, we need a few hundred paying households to sustain two engineers in Austin. That feels like an honest bar.
What's next
We're working on a web view for caregivers who prefer to log from a desktop or tablet. After that: a caregiver hand-off notification system (push notifications summarizing what happened in the last 4 hours, sent when you take over a shift).
We don't have a public roadmap. What we do have is a shared log that works at 3am. We'll keep building from there.
