A System on the Brink

The 2026-2027 Petpocalypse is coming

Tens of millions of new pets acquired worldwide in the first year of Covid. The largest surge in recorded history
10% of vet clinics were corporate-owned in 2015; today, >60%. Costs increased by 63%, owners unable to afford care 264%*
There is a global shortage of vets; particularly specialists (∼500 cardiologists worldwide)
Around 40-50% of pets develop chronic conditions by age 6-7
2026-2027: the Covid cohort turns 6-7
Tens of millions will enter chronic disease
The veterinary system fractures

* UK, mirroring global pattern. 264% increase measured by Blue Cross emergency applications.
** Our founder's father lived 39 years with an undiagnosed cardiac condition that would have been fatal — passing every check-up because no one listened to his heart for longer than 30 seconds. Sonus exists so others don't have to
Sonus Health is the clinical infrastructure layer for a capacity-constrained veterinary system

One specialist. Many clinics. Every pet. In 30 seconds.
Sonus turns specialist care from scarce labour into scalable clinical infrastructure. Enabling vets and nurses to deliver specialist-guided assessments in-clinic and at-home
Vets, nurses, or owners hold a smartphone against the animal. End-to-end proprietary audio AI extracts hospital-grade physiological data in 30 seconds
The platform creates a unified pet health record. Specialists require only minutes to sign off on the final report. Sonus then automatically follows up with owners, increasing conversion

Sonus increases clinic revenue and improves patient outcomes – without increasing headcount
Operational in CVS Group clinics
Instant preliminary results
Powering the modern veterinary operating model

500 cardiologists worldwide. Sonus turns each into many.
Accelerate the shift to roaming (peripatetic) specialist models corporates are actively pursuing by enabling scarce, high-cost specialists to cover many clinics
Support the shift to nurse-led clinics, triage and escalation by giving nurses specialist-guided assessment capabilities
Increase follow-up conversion and clinic revenue through automated reports, reminders and owner communication
Open new recurring revenue streams via remote and longitudinal monitoring at home, improving patient outcomes

Sonus powers the strategy large vet groups are already pursuing: specialist leverage, nurse activation, cost-effective care

CVS Group Numbers
Sonus' reports correlated perfectly with my findings - a great tool for between checks, for me to monitor my patients as diseases progress, and for our nurses to use when they suspect a murmur or arrhythmia

How clinics deploy and monetise Sonus

A clinic or group subscribes, unlocking scanning, reporting and monitoring tools on flexible credit-based plans
Clinics invite the owner, upload the health record and set up a paid care plan for the animal, charging the client directly at a 30–50% margin
Vets or owners scan at home or in-clinic, yielding instant HR, HRV and murmur results that also appear on the clinic internal dashboard
A board-certified specialist cardiologist report is delivered within 24 hours and automatically integrated into the patient's health record
Report findings trigger owner explainers, reminders, clinic follow-up and repeat scans, driving ongoing care and follow-up revenue

Sonus gives clinics a scalable platform for cardiac screening, reporting and follow-up – increasing access to specialist care while creating a monetisable workflow

End-to-end proprietary
Automatic auscultation automates the process of a doctor analysing body sounds using a stethoscope. In our case, without the doctor or the stethoscope – only a smartphone

Sonus combines end-to-end proprietary Digital Signal Processing and Machine Learning, built on 5+ years of fully in-house data and R&D

To our knowledge, we are the only company in the world that has achieved automatic auscultation using smartphones

Appendix A: Health metrics captured

Sonus captures everything a cardiologist can measure during auscultation in-clinic
Anywhere, anytime – even if the patient is asleep at home

Immediate preliminary results
Instant top-level results after each scan, including heart rate (HR), heart rate variability (HRV) and murmur indications (e.g. MMVD)
Report request for full results
The clinic then buys a specialist report reviewed by a board-certified cardiologist, who evaluates the AI output and recording via a custom dashboard. The report assesses all health metrics listed below
Report delivery in 24 hours
The report is delivered on-platform, taking into account all current and historical patient context (age, weight, clinical background, breed, meds) in its assessment of murmurs, arrhythmias, therapy response, disease progression

Full list of metrics and conditions captured
Core cardiac metrics
  • Heart rate (resting, exertional, situational)
  • Heart rate variability (HRV) and autonomic balance
  • Beat-to-beat variability patterns
  • Persistent bradycardia or tachycardia
  • Rate control adequacy over time
Heart rhythm & electrical stability
  • Normal sinus rhythm
  • Respiratory sinus arrhythmia (benign vs pathological)
  • Premature beats / ectopy (isolated or recurrent)
  • Atrial fibrillation (presence, rate control)
  • Sinus node dysfunction indicators (pauses, bradycardic trends)
  • Irregularly irregular rhythms
  • Changes in rhythm over time (longitudinal trend detection)
Heart sounds & structural indicators
  • Presence or absence of heart murmurs
  • Murmur intensity and progression
  • Timing of murmurs (e.g. systolic, post-S1)
  • Early signs of valvular disease (e.g. MMVD)
  • Murmur changes suggesting chamber dilation or disease progression
  • Differentiation of cardiac vs non-cardiac sounds
Disease detection & progression
  • Myxomatous mitral valve disease (early detection → progression)
  • Hypertrophic cardiomyopathy indicators
  • Dilated cardiomyopathy–associated changes
  • Advanced heart disease stability vs deterioration
  • Progression risk signals (e.g. falling HRV, rising resting HR)
  • Longitudinal disease trajectories rather than single snapshots
Therapy monitoring & response
  • Antiarrhythmic therapy effectiveness
  • Rate-control adequacy in atrial fibrillation
  • Atenolol and beta-blocker response
  • Detection of worsening after medication changes
  • Post-operative cardiac recovery
  • Stability on chronic cardiac medication regimens
Event-based and situational monitoring
  • Syncope / fainting episodes
  • Collapse during or after exertion
  • Intermittent events not reproducible in clinic
  • Physiological changes during real-world episodes
  • Situations where ECGs or Holters fail
Risk reduction & clinical workflow
  • Post-discharge deterioration
  • Unexpected progression between visits
  • Anaesthetic risk clearance support
  • Reassurance in normal or benign cases
  • Identification of when escalation or referral is truly needed
Appendix B: Lives saved
60+
Cat and dog lives saved in three months, by identifying life-threatening conditions that may otherwise have gone undetected

Shasha (pictured)
"This cat has been losing consciousness. Two 24 hours Holters missed every episode. Around forty Kardia ECGs were reviewed, but every faint produced indecipherable data."
Shasha, a 3-year-old Persian cat was repeatedly losing consciousness at home. Emergency, specialist and cardiology work-up, including repeated ECGs in-clinic, and Holter and Kardia monitoring at-home, failed to identify the cause
Shasha was put on meds for her heart, but deteriorated dramatically within 48h. With loss of consciousness continuing, her team reached out to Sonus to capture her heart during fainting episodes
Within two reports, we determined Shasha’s heart rhythm was stable during episodes but rather identified respiratory sounds indicating the issue was an upper-airway obstruction, not the heart. This had been missed as Shasha was routinely given a calming drug for clinic visits, masking her breathing issues that owners had mistaken for purring
Sonus reframed the case, redirected care, and avoided escalating the wrong diagnostic path — preventing a fatal outcome
