Angel investments
Companies we’ve backed
Alongside TLR Ventures’ core investment thesis, we also back founders directly through personal angel investment, choosing companies built on the same principles we look for everywhere else: strong fundamentals, real conviction, and a genuine shot at solving a meaningful problem.
These are early bets made with the same discipline and hands-on belief that define everything TLR does, just at an earlier stage and a smaller scale.
Alethios
Making health research accessible to everyone.
Alethios builds software that lowers the barriers to running and participating in high-quality decentralized health research, giving researchers AI-powered tools to design studies, recruit participants, and collect real-time data, while making it dramatically easier for everyday people to take part in the studies that advance human health. By replacing the slow, high-friction processes of traditional trial sites with a digital-first approach, Alethios is helping researchers reach faster results and a participant pool that better reflects the population at large.
Precision Livestock Technologies
Bringing computer vision to the feedlot.
Precision Livestock Technologies applies machine vision to cattle feeding operations, replacing unreliable manual observation with continuous, real-time monitoring of feed bunks and feeding behavior, giving operators the accuracy and insight to run their feedlots with data instead of guesswork. The platform turns what used to be a subjective, labor-intensive process into a continuous stream of actionable data, helping operators catch problems earlier and run more efficient, more profitable operations.
HealthRhythms
Turning a smartphone into a mental health early-warning system.
HealthRhythms uses passive smartphone sensor data (movement, sleep, and activity patterns) combined with AI to assess and predict a person’s mental health status in real time, giving providers and health systems the ability to identify and intervene in mental health challenges long before a crisis point. Rather than relying on a patient to self-report or wait for a scheduled appointment, HealthRhythms continuously tracks the everyday signals that reveal how someone is actually doing, closing a gap that has long left mental health care reactive instead of proactive.
WavelyDx
Diagnosing ear infections, right from home.
WavelyDx turns a smartphone into a diagnostic tool for one of childhood’s most common ailments, using soft acoustic chirps to detect ear fluid and flag a likely infection in minutes, helping parents skip unnecessary trips to the doctor while getting a clear answer on when care is actually needed. This technology gives families a fast, at-home way to make an informed decision about the next step. The result is a decrease in unnecessary clinic visits, costs, and time away from work.
Yuppasoft
AI-driven optimization for institutions that run on complex scheduling.
Yuppasoft builds AI-powered software that solves complex resource-allocation problems, starting with academic scheduling for universities and school districts. The software is helping institutions build more efficient, more equitable schedules that maximize both resource use and student access. By automating a process that’s traditionally manual, time-consuming, and prone to error, Yuppasoft frees up administrators to focus on the decisions that actually require human judgment.
