Company profile

researched Aug 2026

BloomAPI, Inc. is a Seattle-based healthcare communication software company that operates the BloomText platform. BloomText is a HIPAA-compliant texting and messaging service that lets clinics and care organizations exchange text messages, images, documents and links with patients, clients and family members by SMS or email without requiring recipients to install an app or create a password. Additional product capabilities include internal team messaging with read receipts and notifications, document and insurance-card scanning, file sharing, broadcast SMS messaging to contact groups with real-time send controls, a shared patient inbox, group texting and video calling. Every account is provided with an automatically signed Business Associate Agreement, and the mobile app is designed to keep protected health information inside the application rather than on staff phones, with single-button removal of staff members.

The company's original product addressed medical-records transfer. Software installed in a doctor's office connected to the practice's electronic medical record system, retrieved requested records and transmitted them to patients, other physicians or insurers, replacing fax and postal mail. The company positioned this as building connections into EMR systems that could also serve as an application platform for other healthcare vendors, which is the origin of the "API" in its name. It cited industry spending of roughly $2.5 billion per year on records transfer and high failure rates for faxed records.

BloomText is marketed for specific care settings including ABA therapy, addiction treatment, dental, home health, home care and mental health, and the company publishes comparison and compliance-education content covering alternatives such as Microsoft Teams, Slack, WhatsApp, iMessage, Zoom, Google Voice and healthcare-specific messaging vendors.

Founding story

Michael Wasser founded the company in Seattle after selling his prior software company, Raveld, to Apptio. Working in the industry, he concluded that a communication link was missing because many electronic medical-record systems cannot exchange data with one another, leaving clinics dependent on error-prone faxes that frequently fail to reach the intended recipient.

Business model

BloomAPI sells its BloomText messaging platform directly to healthcare organizations as software, offering published plans and pricing alongside a free tier that includes a signed Business Associate Agreement and requires no credit card to start. A third-party profile lists subscription and fee-for-service revenue streams. Apps are distributed through the Apple App Store and Google Play as well as Mac and Windows desktop downloads, and the company publishes developer documentation and an API reference.

Paid plans are published on the company website with a free tier that includes a signed BAA and no credit card requirement; a third-party profile lists subscription and fee-for-service revenue streams.

Traction

As reported on the company website, BloomText has been used by 21,000 users covering 295,000 patients, with 28 million messages sent and 30,000 video calls. The Android app lists more than 5,000 downloads. In July 2017, the earlier records product had 300 doctors in its network, was transmitting records for more than 1,000,000 patients, and the company employed five people.

Latest developments

The BloomText Android app was last updated in August 2026 with fixes and improvements, and the company website carries a 2026 copyright notice for BloomAPI Inc. The site reports cumulative usage of 21,000 users, 295,000 patients, 28 million messages sent and 30,000 video calls. A third-party profile lists Tyler Brown as chief executive officer with Michael Wasser as founder and board advisor.

Full profile — market position, technology, go-to-market, geography, history

Market position

The company competes in the healthcare secure-messaging and patient-communication category, positioning BloomText against clinical messaging vendors such as TigerConnect, OhMD, Spruce, Klara, Rhinogram, pMD, Doximity Dialer, Hucu.ai, QliqSOFT and Celo Health, as well as general-purpose tools including Microsoft Teams, Slack, Google Workspace, WhatsApp, iMessage, Zoom, Signal, Google Voice, Textline and Connecteam. A third-party directory categorizes it under communication and healthtech with fewer than 10 employees.

BloomText emphasizes that patients and family members can receive and reply to secure messages by SMS or email without downloading an app or maintaining a password, while protected health information remains contained within the platform rather than on staff devices. Accounts include an automatically signed Business Associate Agreement at sign-up and a free entry tier. In its earlier records-transfer business, the company distinguished itself from competitors that improved or outsourced faxing by running software inside the physician's office that automated and digitized record transmission between systems in higher-quality formats.

Technology

BloomText is delivered as web, iPhone, Android, Mac and Windows applications with an API and developer documentation. Messages can be delivered by SMS or email to recipients without an app or password, and features include read receipts, notifications, document and image capture, file sharing, broadcast SMS with pause and rate controls, and video calling. Data is encrypted in transit and users can request data deletion. Analytics use Google Analytics with anonymized IP, Amplitude and an internal analytics system. The company's public GitHub organization contains Go, JavaScript, Shell, C++ and Objective-C repositories including datasource loaders for a public data API, Postgres CSV bulk-loading tools, Let's Encrypt automation for Google Cloud load balancers, Node.js FreeRDP bindings and forks of React Native audio, image-picker and notification libraries. The earlier product installed software in physician offices that interfaced with legacy electronic medical record systems to extract and transmit records while enforcing privacy permissions.

Go-to-market

The company uses self-service online sign-up with a free, no-credit-card entry point and a signed BAA issued immediately, supplemented by scheduled demos, published pricing and a cost calculator. Content marketing includes a blog, product guides, a HIPAA texting glossary, explainer pages on BAAs, PHI and broadcast texting, and head-to-head comparison and HIPAA-compliance pages targeting named alternative messaging tools. Mobile and desktop app store distribution supports adoption by clinical staff. In its earlier records business, funding was directed at building a Seattle-based engineering, operations and sales team to meet demand from small and medium-sized clinics.

Healthcare organizations and clinical practices and their staff, including radiology, family medicine and acute care providers, plus segment-specific offerings for ABA therapy, addiction treatment, dental, home health, home care and mental health providers. End recipients include patients, clients and family members. The earlier records-transfer product served small and medium-sized clinics, physicians, insurers and patients.

Geography

The company is headquartered in Seattle, Washington, with addresses listed at 1904 3rd Ave Ste 228, Seattle, WA 98101 and 300 Lenora Street #963, Seattle, WA 98121. Its early records network spanned 300 doctors across the United States, and staff were based in Seattle's Belltown neighborhood.

History

The company was founded by Seattle entrepreneur Michael Wasser, who turned to healthcare after selling his previous software company, Raveld, to Apptio. BloomAPI went through the Y Combinator accelerator and officially launched its medical-records product around late 2016, reaching 300 participating doctors and about five employees in Seattle's Belltown neighborhood by mid-2017, when it raised $2.4 million. The corporate entity remains BloomAPI, Inc., while the current product and brand are BloomText, a HIPAA-compliant texting platform. A third-party company profile lists Michael Wasser as founder and board advisor and Tyler Brown as chief executive officer.
