Why Njinju Labs exists
Every product we build was born from a problem we lived firsthand — in the lab, in the field, and in everyday life.
As a university professor, I saw firsthand that faculty searching for the best graduate students and postdocs had no reliable platform to do so. Meanwhile, the most qualified candidates — lacking exposure — watched their dreams stall. We are building the platform that closes this gap.
Joint inversion of gravity, magnetic, and MT data is among the most powerful tools in subsurface imaging — yet no affordable and user-friendly, researcher-built software exists for it. GeoJointinv was created to fill that void, built by someone who does the research, not someone guessing at it.
Sleep consistency and food waste are silent crises affecting millions. SleepKith and SaveExcess are our answer — practical, zero-friction tools that make a measurable difference in daily life without requiring expensive hardware or subscriptions.
How we're structured
Each department operates independently but shares the same mission — build tools that solve real problems.
Our products
“Consistency is everything. SleepKith makes it measurable.”
For anyone who wants to sleep better, consistently. Log sleep and wake times, build a Sleep Score, and track your streaks — no wearable required.
For food donors, volunteers, and people who hate waste. Connect surplus food with people who need it — in real time, before it goes in the bin.
“Every meal rescued is a small act of change for the community.”
Land your PhD or postdoc in geoscience.
Tell us your research interests, and GeoSciMatcher finds the professors whose work aligns with yours — pulling from real federal funding data and publication records. Pro users get AI-written cold emails tailored to each professor, a saved shortlist, and a full PDF report.
For exploration geophysicists and researchers. Professional desktop software for joint inversion of gravity, magnetic, and MT data — built from peer-reviewed research, designed for real workflows.
“Built by a geophysicist who does joint inversion research — not a software company guessing what you need.”
AI-powered operations
Njinju Labs is building two AI agents that operate as full employees — handling intelligent workflows across both departments so humans can focus on what matters.
Nora handles intelligent matching, user support, and operations for AcadMatcher and consumer apps. She processes graduate profiles, surfaces the best professor-student matches, and manages onboarding flows — available 24/7.
Rex is the AI specialist for the geoscience division. He assists GeoJointinv users, supports training enquiries, matches geoscience students with mentorship opportunities, and helps researchers navigate joint inversion workflows.
Geoscience Dept. · Research & Training
Structured training for geoscientists at every stage — from graduate students to senior exploration teams.
About Njinju Labs
Njinju Labs LLC was founded by a university professor and geophysical researcher who saw critical gaps in the world — in how academics connect, how food gets wasted, how geoscience software falls short — and decided to build the solutions.
With peer-reviewed research publications, live apps on both major app stores, and deep domain expertise in joint inversion, Njinju Labs sits at a rare intersection that no other company occupies.
In geosciences, most Ph.D. students take 3+ years to achieve their first publication. Dr. Njinju mentored a student from Africa and guided them to publish in under 2 years — cutting the timeline nearly in half.
This is the standard of mentorship that drives everything we build at Njinju Labs.
