What FoodMarble does

FoodMarble Digestive Health Ltd. is an Irish health-technology company founded in 2016 by Aonghus Shortt (CEO), Peter Harte (CTO), and Lisa Ruttledge (COO), with the company's origin tied to Shortt's partner Grace Whittle's experience with IBS. The company developed and markets the AIRE 2, described as the world's first personal digestive breath tester — a portable Bluetooth-enabled device that measures hydrogen and methane levels in exhaled breath to help individuals identify food intolerances and manage conditions such as IBS, SIBO, and IMO. A companion iOS/Android mobile application tracks breath scores, meals, symptoms, sleep, and stress, with added features including personalized breath-score tracking, FODMAP Recommended Daily Allowance (RDA) visualization, barcode food scanning, and weekly summary reports. The underlying technology is supported by over a decade of scientific research and has been independently validated through peer-reviewed studies at Harvard, Johns Hopkins, and McMaster University, published in Gastroenterology (2025), Clinical & Translational Gastroenterology (2025), and Digestive Diseases & Sciences (2024), with reported 100% diagnostic agreement against clinical breath-testing devices.

The company monetizes primarily through direct-to-consumer sales: the AIRE 2 device is priced at $269 on a special discount (regular $299), and the Food Intolerance Kit (lactose, fructose, sorbitol, and inulin FODMAP sachets bundled with a 6-Week Discovery Plan) is priced at $39. Distribution runs through the foodmarble.com e-commerce storefront, Amazon marketplace, and a separate FoodMarble Health portal (foodmarble.com/gi) serving physicians and clinical users. The company ships globally to 30+ countries including the US, UK, EU member states, Canada, Australia, and New Zealand; US customers can use HSA/FSA payment, and free shipping is offered. Marketing relies heavily on earned media (BBC, CNN, Forbes, Financial Times, Wall Street Journal, Vogue coverage) and content marketing, with the AIRE 2 having received a Red Dot Design Award.

FoodMarble is privately held, headquartered at the Guinness Enterprise Centre in Dublin, Ireland, with 11-50 employees. The leadership team includes co-founders Aonghus Shortt (CEO), Peter Harte (CTO), and Lisa Ruttledge (COO), alongside Dr. James Brief (Chief Medical Officer, gastroenterologist) and Dr. Claire Shortt (Chief Scientist). The company has accumulated more than 80,000 users and over 9 million breath tests, and has raised approximately $8.7M across multiple rounds from SOSV (HAX), Breed Reply, Delta Partners, Enterprise Ireland, HBAN, and Business Venture Partners.

Core offering

FoodMarble designs and sells the AIRE 2, the world's first personal digestive breath tester — a portable, pocket-sized device that measures hydrogen and methane levels in breath via a proprietary sensor array. The device pairs over Bluetooth with a companion mobile app (iOS/Android) that logs breath scores, meals, symptoms, sleep and stress, and runs users through a structured 6-Week Discovery Plan to identify FODMAP food intolerances (lactose, fructose, sorbitol, inulin) for people managing IBS, SIBO and chronic bloating.

Product overview

FoodMarble offers a unified digestive health tracking system consisting of the AIRE 2 breath testing device as the core hardware product, paired with a companion mobile application that tracks breath scores, meals, symptoms, sleep, and stress. The Food Intolerance Kit is an add-on module containing FODMAP test sachets (lactose, fructose, sorbitol, inulin) that work with the device for targeted food intolerance testing. A protective carry case is included with the device. Users progress through a 3-stage program: Baseline (establishing baseline readings), Reset (reducing trigger foods), and Discovery (testing specific FODMAPs). The system enables at-home hydrogen and methane breath testing to help users with IBS, SIBO, and food intolerances identify their personal food triggers.

Direct peers

• Lumen: Lumen makes a handheld breath analysis device (measuring metabolic markers via CO2) paired with a mobile app — the closest direct competitor to FoodMarble in form factor, GTM (D2C + app), and target use case of personal metabolic/digestive insights.
• QuinTron Instrument Company: Established manufacturer of clinical hydrogen and methane breath test analyzers used by hospitals and SIBO testing labs. A direct competitor in breath-based digestive diagnostics, though operating in the clinical/B2B channel rather than consumer.
• Cairn Diagnostics: Specializes in clinical breath-based diagnostic testing services (e.g., SIBO, lactulose testing) for gastroenterology practices. Competes with FoodMarble in the same clinical breath-testing workflow, but on the service/provider side rather than consumer hardware.

Broad incumbents

• Bedfont Scientific: UK-based medical device manufacturer with a broad breath analyzer portfolio spanning smoking cessation, COVID screening, and gastrointestinal diagnostics. Comparable because of its hydrogen/methane breath testing products, though it serves the clinical channel broadly.
• Levels Health: Continuous glucose monitor (CGM)-based metabolic health consumer platform. Comparable as a consumer health-tech hardware + subscription data product serving biohacking-adjacent consumers with personalized insights, overlapping with FoodMarble's gut-health-meets-data positioning.
• Oura: Smart ring with subscription app for sleep, recovery, and metabolic health. Comparable in D2C health hardware + app + subscription model and in the premium consumer health-tech segment, though focused on wearable biometrics rather than breath diagnostics.
• Whoop: Subscription-based wearable health monitor for recovery, strain, and sleep. Comparable as a premium consumer health-tech brand with a hardware-plus-recurring-revenue model and similar global D2C distribution playbook.

Emerging players

• Oshi Health: Virtual-first gastroenterology care platform combining telehealth, dietary coaching, and at-home diagnostics for IBS/IBD patients. Competes with FoodMarble for the digestive-health patient journey, but delivers care through a service model rather than hardware.
• Vivante Health: Digital digestive health platform offering GI care programs to employers and health plans. Comparable in addressing the same IBS/SIBO patient population and employer-channel economics, though delivered through a coaching/clinical model rather than a device.
• Ayble Health: Digital therapeutics platform for GI conditions using AI-driven personalized nutrition for IBS patients. Targets the same user (chronic digestive sufferers seeking trigger identification) with a software-first approach that could complement or compete with FoodMarble's hardware.
