Pear Bio analyzes patient tumor samples and data with a proprietary computational biology platform to deconvolute complex cancer biology and drive patient-centric functional precision medicine and drug discovery.
Our ultimate goal is to optimally allocate approved treatments to cancer patients who will benefit from them, while creating novel therapies that are purpose-designed for patients who dont respond to available treatments.
The platform uses microphysiological systems and 3D computer vision to measure cancer progression over time. Pear Bio cultures patient tumor samples with matched blood into 3D immune-microtumors to test potential treatment options and combinations ex vivo. A proprietary computer vision/DL pipeline finds image-based spatial biomarkers in time-course 3D microscopy data of patient 3D immune-microtumors. Each treatment option is compared using these image biomarkers to predict which treatments have high potential efficacy for each patient.
Patient data and excess tissue/blood feed into a multi-omics pipeline, which allows us to find novel druggable targets in patients who dont respond to approved therapies. These targets are then developed into our in-house drug discovery pipeline, which eventually feeds back into clinical care through our predictive biomarker platform.

A Tamarin é uma plataforma premium de saúde clínica e comportamental focada em resolver o maior gargalo financeiro do emagrecimento moderno: a adesão ao tratamento.
Enquanto dados reais mostram que até 68% dos pacientes abandonam o GLP-1 no primeiro ano, a Tamarin une a prescrição médica com o acompanhamento diário do nosso assistente virtual.
Nós transformamos prescrições de alto custo e alta evasão em mudanças de vida sustentáveis, garantindo manutenção de resultados clínicos para os pacientes e proteção do ROI de saúde para nossos parceiros corporativos.
Saúde que cabe no seu dia. Resultados que duram uma vida.
O começo:
Em 2021, um endocrinologista disse a Mel que ela estava mentindo. Que era impossível treinar como ela treinava, comer como ela comia, e ainda ganhar peso. Ele não perguntou sobre a tireoide. Não perguntou sobre perimenopausa. Não investigou se a exaustão, o peso e os marcadores metabólicos estavam conectados. Ele já tinha o diagnóstico antes dela terminar de falar: esforço insuficiente.
O sistema está errado. Os tratamentos que abordam os mecanismos metabólicos por trás do peso, da energia e da saúde hormonal existem. São aprovados pela ANVISA. O acesso a eles permanece fragmentado, caro, e, quando uma mulher finalmente alcança um médico, condicional a ela convencê-lo de que já se esforçou o suficiente.
Quando Mel finalmente recebeu o tratamento certo, sua tireoide estabilizou pela primeira vez em vinte anos. O peso mudou. A energia voltou. Isso não é uma história de falha pessoal. É uma falha estrutural.
Por que Tamarin?
Em 1970, restavam menos de 200 micos-leões-dourados no Brasil. Hoje, mais de 4.800. A espécie não se recuperou por resiliência. Recuperou-se porque um programa coordenado, brasileiro, de décadas, baseado em ciência, finalmente aplicou a intervenção certa na escala certa. O esforço individual já estava esgotado. O que mudou o desfecho foi estrutural.

The attention economy is the greatest commercial force on the planet. 50 million creators, athletes and talent sit on the highest-trust audiences in history and their fans signal purchase intent every single day in comments, DMs and community posts.
The problem is infrastructure. Tracking that intent manually is impossible. Billions are left on the table.
Converting it into structured, scalable commerce requires capabilities most attention-driven businesses cannot build alone, no matter whether you are a creator with a million followers, an athlete with a global fanbase, or an agency managing both.
GYST fixes this. Our AI reads audience signals across social platforms simultaneously, identifies validated commerce opportunities in under 30 seconds, and deploys autonomous agents to execute the full commerce loop, from product concept, supplier sourcing, store build, marketing, payment and fulfilment.
The creator or athlete approves. GYST handles everything else.
For merchants and commerce partners, GYST surfaces creator audiences that are already generating purchase intent around your product category and connects that demand directly to your existing infrastructure. We bring you buyers, not browsers.
Our intelligence layer sits upstream of every commerce platform, integrating with TikTok, Instagram, YouTube and more, making existing infrastructure more valuable rather than replacing it. We are the OS, not the storefront.
Agentic commerce grew 6,900% last year. The pipes for the attention economy havent been built yet. Thats why GYST is here.
