Kinomatic, an Arroyo Grande, California company that uses artificial intelligence and virtual reality to plan joint replacement surgery, announced a $4m seed round on 18 June 2026. Waterline Ventures led the round. No other investors were named and no valuation was disclosed.
The company said the money will pay for hiring in critical roles, a new office and further development of its AI-enabled surgical planning platform, with a focus on long-term, opioid-sparing outcomes.

What Kinomatic does
Kinomatic, founded in 2021, focuses on total knee and hip replacement patients. Its platform combines custom 3D pre-operative modelling, VR surgical simulation, post-operative recovery optimisation, long-term outcomes tracking and concierge care.
According to the announcement, it analyses more than two million data points and over 1,000 measurements per patient to choose from more than 30,000 possible implant configurations. HIT Consultant reported the same figures. The aim is a surgery tailored to the patient rather than a standard implant and approach, with attention to recovery and to reducing the need for opioid painkillers.
The company reports seven-fold revenue growth over four years, a five-fold expansion in provider relationships and a Net Promoter Score of 85. These are the company's own figures.
HIT Consultant says the funds will expand engineering roles, open a new centralised office and speed development of what it calls an AI-native surgical planning and VR simulation platform. The press release says the platform also covers long-term outcomes tracking, meaning patients are followed after surgery, and that Kinomatic partners with leading surgeons across the country. It did not name them. HIT Consultant quoted Lea saying, "Longevity is no longer a fringe concept."
A new chief medical officer
Alongside the round, Kinomatic announced that Dr Andrew B. Wickline, an orthopaedic surgeon, has joined as chief medical officer. He said: "For too long, recovery has been the forgotten phase of joint replacement."
Chief executive Shaun Lea said: "Patients expect more than just 'good enough' from their care."
The company did not give a headcount or the number of patients it has treated.
The investor
Waterline Ventures is a healthcare-focused venture firm, according to HIT Consultant. Its managing partner, Robbie Greenglass, said the platform is built around the patient and gives surgeons data and tools they did not previously have.
The announcement does not name any other participants in the seed round, and does not say whether Kinomatic had raised money before. Because of that, no funding history is given here.
What to watch
Kinomatic's plan for the money is modest: key hires, an office and platform development. The company has not said how many surgeons or hospitals use the platform.
Neither the announcement nor HIT Consultant's report supplied clinical data on opioid use after surgery, which is the outcome the company says its approach targets.
The company is based in Arroyo Grande, California, and was founded in 2021. It did not say how much it had raised before this round or how many people it employs.
