Company profile
researched Aug 2026Filament Labs is an Austin, Texas healthcare software company founded in March 2013. Its flagship product, Patient IO, is a care plan delivery and patient engagement platform that lets health professionals build fully customizable, personalized care plans and deliver them to patients outside the clinic. Patients, family members and caregivers receive treatment-specific tasks, reminders and educational content on their smartphones, and the platform synthesizes care plans from multiple providers into a unified set of daily tasks.
On the provider side, a web dashboard lets clinicians track an entire patient population, review submitted health information in real time, and receive user-configurable alerts when patients deviate from their care plans so attention can be focused on higher-risk patients. The company positions the product around adherence to complex treatment regimens and the tracking of patient health behaviors between visits. Patient IO exposes a full set of APIs intended to make it integrate with existing care management software, electronic health record systems and population health programs, an architectural decision the founders described as strategic given that clinicians do not want an additional standalone dashboard. Following the 2014 seed round, the company said it would extend the platform with mobile-web and email touch points to reach patients without smartphones.
Founding story
Filament Labs was founded in March 2013 by CEO Jason Bornhorst, previously #2 and director of product management at mobile travel app maker Mobiata, which was acquired by Expedia in 2010; Chief Product Officer (later described as CSO) Colin Anawaty, who created the Plerts emergency service that was acquired by Rev Worldwide in 2010 and who previously worked on mobile financial products and mobile entertainment apps; and CTO Brian Gambs, whose background includes HealthShare and WebMD and an earlier company sold to SunGard Data Systems. They were joined by Head of Mobile Sebastian Celis, a former Mobiata and Expedia iOS lead. The founders' first product was a health and wellness app built with Aetna within four months, following a relationship begun at a 2012 SXSW panel; the company later pivoted to Patient IO.
Business model
Filament Labs sells Patient IO as a SaaS patient engagement platform to healthcare providers and provider organizations. The product is offered with a full set of APIs so it can be embedded in existing care management software, electronic health records and population health programs rather than sold only as a standalone dashboard. Distribution partners such as athenahealth provide access to large provider networks, and early customers including Corinthian Health Services and Arcadia Home Care & Staffing both deployed the platform and invested in the company.
Software-as-a-service subscription platform sold to healthcare providers, with API access enabling integration into third-party care management, EHR and population health systems.
Traction
Patient IO had been deployed to approximately 4,000 patients as of April 1, 2014, with another 4,000 planned for June 2014, and was live across Corinthian Health Services' 20 clinics. By the time of the athenahealth investment the platform was deployed at 27 clinical sites and the team had grown to 11 people, most of them developers. Gust listed 5 employees and a "Full Product Ready" stage.
Latest developments
Filament Labs joined athenahealth's More Disruption Please accelerator, receiving a $3.32 million investment from athenahealth along with mentorship and office space, and agreeing to integrate Patient IO with athenaNet to serve athenahealth's patient engagement, chronic care management and population health needs. At that point Patient IO was deployed at 27 clinical sites and the team numbered 11 people.

Market position
Filament Labs is one of a number of digital health startups using smartphones to connect patients and clinicians during the final stage of care delivery. Its investor Mercury Fund characterized the mobile healthcare space as noisy and driven by consumerization of information technology, and described the company as focused on user experience. Gust listed the company in the Healthcare Services industry at the "Full Product Ready" stage.
Filament Labs positions Patient IO as API-first, designed to be integrated into electronic health records, population health programs and existing care management software rather than operating as another standalone clinician dashboard. The company states it offers a full set of APIs unlike other care plan solutions, and that the platform was built in collaboration with patients and providers to fit existing healthcare workflows, with an emphasis on user experience and on unifying care plans from multiple providers into a single patient task list.
Technology
Patient IO is a cloud-based SaaS platform combining smartphone delivery of treatment-specific tasks, reminders and educational content with a provider-facing web dashboard for population tracking, real-time review of patient-submitted health information, and configurable alerts for care plan deviation. Its API-first architecture is intended for integration with EHRs and care management software, including athenaNet, and the roadmap included mobile-web and email channels for patients without smartphones.
Go-to-market
The company sells directly to healthcare providers and provider organizations such as infusion clinics and home care agencies, and expands through platform partnerships — notably athenahealth's More Disruption Please accelerator, which opened access to a network of 72,000 healthcare providers via integration with athenaNet. Early customers doubled as investors. As it expanded within the athenahealth program the team, which was mostly developers, was adding sales, engineering and customer success roles.
Health professionals and provider organizations managing patients between visits, including infusion clinics, home care and medical staffing agencies, health systems using EHR or population health programs, and patients with complex or chronic treatment regimens along with their families and caregivers.
Geography
Headquartered in Austin, Texas, with office space provided by athenahealth at its Seaholm Power Plant location in Austin. Customer deployments cited are in the United States, including Texas-based Corinthian Health Services and Arcadia Home Care & Staffing.
History
The company was founded in March 2013 in Austin, Texas and went through the Techstars Austin accelerator, raising $160,000 in connection with the program. An earlier product was a health and wellness application built with Aetna and launched alongside other venture-backed companies; the company subsequently pivoted to Patient IO. In May 2014 Filament Labs announced a $1 million seed round led by Mercury Fund, at which point Patient IO had been live for two months across Corinthian Health Services' 20 clinics and had reached roughly 4,000 patients as of April 1, 2014. Company leaders spoke at Austin startup events including a Startup Grind Austin fireside chat with co-founder Colin Anawaty in November 2014. The company later joined athenahealth's More Disruption Please accelerator, which included a $3.32 million investment from athenahealth and integration of Patient IO with athenaNet.
