Why We Are Building Nobokai Care

The problem

People are living longer, and most want to age at home. The number of Americans aged 85 and over will double by 2040. The people who give that care are too few: home care loses about three in four caregivers every year.

Home care agencies carry this. They are small businesses doing some of the most important work there is, and most can’t afford to staff a phone line around the clock. When a daughter calls at 8pm about her mother and no one answers, she calls the next agency, or her mother goes without care. The staff who stay spend their days on phone calls, schedules, forms and state portals instead of on people.

Hiring alone can’t close this gap, because there aren’t enough people. What we can change is how much each person is able to do. Coding agents made engineers many times more productive. Care teams still run on phone tag and paperwork. We are building the agents for them: voice agents that answer every call and turn it into completed office work, inside the tools agencies already use, with a person approving anything that changes someone’s care.

Why this is personal

Tausif

Care has been the thread in what I build since I was a kid. At 14, I built an internet-connected pill dispenser for my grandma so she could take the right medicine at the right time. In high school I prototyped ProCure, a QR-based prescription system for patients, doctors and pharmacists in Bangladesh. It never went past a prototype, but it showed me that much of care breaks down in records and handoffs, not at the bedside.

Since then I’ve worked on assistive technology: smart skin patches in a miniature robotics lab at Vanderbilt, and a passive bedside monitor for elderly patients as my senior design project. I also built voice agents at the edge, including an open-source ESP32-S3 voice-agent board I designed end to end, now used in AI toys. When we saw how understaffed home care agencies are, everything I had worked on pointed at the same problem: voice agents, technology people depend on, and care.

At Vanderbilt, I built AI tools alongside nursing faculty, researchers, students and caregivers, with collaborations at Vanderbilt University Medical Center. Through regular consultations with nurses and nursing students, I saw that access to AI alone wasn’t enough. They needed tools that understood their work and followed rules they could trust. I coauthored two nursing AI papers and led AI coaching and workshops.

As a software engineer at Oracle, I worked on OCI infrastructure automation and healthcare projects. Working with home care agencies brought these experiences together: their teams needed tools that knew their people, rules and routines. That is what Nobokai Care is.

Our promise

Care is human work. Sitting with someone, noticing what has changed, comforting a family: that belongs to people. We will take the calls, schedules and forms off their plate, keep a person in charge of every decision about someone’s care, and say clearly when you’re talking to an AI.

We’ll know we’re getting there when no family’s call goes unanswered.
