Data Driven Investors: Why Tau Ventures Invested In Calmwave

Via Data Driven Investor, Written by Amit Garg


Excited to announce our investment in the $4M seed for CalmWave alongside Bonfire Ventures, SeaChange Fund, Hike Ventures, AI2 Incubator, and the co-founders of PagerDuty.


CalmWave helps hospitals systems to manage and reduce alarm fatigue experienced by healthcare workers working in critical care. Tau Ventures is an AI-first fund in Silicon Valley investing primarily in mature seed, typically when there is a pipeline of customers. CalmWave fits right into our thesis and as we followed their progress, what we found especially compelling was their (1) opportunistic product in a ripe SaaS market (2) an execution-focused team, and (3) strong traction.

1) The Need


Even before the COVID pandemic added stress and strain to hospital critical care units, ICUs were overwhelmed by alarms creating sensory experiences that nurses likened to professional football stadiums, casinos, and carnivals, – not somewhere that you want to care for a critically-ill patient or recover from a life-saving surgery. ICUs have recorded decibel peaks above 85 dB and can have a critical alarm every 90 seconds. This might be acceptable if those alarms were all actionable, but instead, 85-99% of those alarms are false positives, amounting to what one nurse described as “little more than anxiety-inducing wild goose chases”. This cacophony of alarms, leads to alarm fatigue – a desensitization to alarms which leads to unsafe patient environments (e.g. clinicians miss or delay response to alarms) and clinician burnout.


Alarm fatigue in healthcare settings has been well documented academically and came to the forefront of institutions in the past decade. As SaaS companies become more and more prominent, especially within the healthcare industry, hospital systems have become more accepting and accustomed to such products, making the market ripe.


2) The Team


The cofounders knew each other from their previous startup PagerDuty. CEO Ophir Ronen is a serial entrepreneur currently in residence at the Allen Institute. He previously started Internap Network Services as well as EE HQ, which was acquired by PagerDuty in 2015. The principal data scientist, Justin Kearns, holds 22 patents and has significant experience in AI and signals processing. Keith Boudreau is the chief engineer in charge of the fullstack development. Christian Bauer is the principal UX Architect and has been recognized by several national awards for his AI-powered healthcare and fintech UX architectures.


3) The Product


CalmWave is building an AI-powered, enterprise-grade operations management platform for hospitals. They’re beginning with an alarm operations, which will allow users to get a continuous window into two key indicators that are otherwise lost in a sea of false alarms. First is a patient acuity score and unified view of patient alarm patterns, the second is the resulting workload on a provider. Potential customers can use these metrics to drive better, more efficient staffing, informed decisions about level of care and discharging patients, and adjustments to alarm thresholds to decrease false positives.


We are honored and excited to be part of CalmWave’s journey, using technology to solve a big healthcare problem.
