Simple<\/a>, an AI-powered health coaching app that helps people lose weight. Then, in 2023, he added its standout feature: an AI coach named Avo, which helps give tailored advice to users\u2019 needs and progress.\u00a0<\/p>\n\u201cWe wanted to help people lose weight without the guilt or grind that is innate to the toxic diet culture,\u201d he said.\u00a0<\/p>\n
Having built the company to a current $160 million in ARR with 700,000 subscribers, he said, Simple announced on Wednesday that it closed a $35 million Series B funding round led by actor Kevin Hart\u2019s HartBeat Ventures. The company has raised $45 million in total funding.\u00a0<\/p>\n
Prytkov had an early co-founder who has since left the company, leaving him at the helm solo.\u00a0\u00a0<\/p>\n
Avo today handles more than 100,000 coaching conversations a day and processes nearly 300,000 daily meal logs, Prytkov said. Users fill out a form to help them build a personalized program, then they are introduced to the AI coach. It collects information, like meal logs, from user input, and it runs assessments that score habits and nutritional quality, he said.\u00a0<\/p>\n

\u201cThe coaching is delivered through a chat powered by LLMs that adapt tone and content to each person, with memory for long-term context and constitution-based fine-tuning,\u201d Prytkov added.\u00a0<\/p>\n
Obviously, the app is a direct competitor to Noom, perhaps the most popular behavioral dieting app in the industry, with millions of users. And it competes with WeightWatchers and MyFitnessPal. Prytkov said it is different from its competitors because it does not offer generic lessons or generally track calories, nor has it ventured into supplying GLP-1 medications.<\/p>\n
\u201cWe provide personalized coaching, not just tracking,\u201d he said. \u201cAvo adapts daily plans across nutrition, fasting, movement, and habits, as it provides real-time meal feedback and tailored check-ins.\u201d\u00a0<\/p>\n
It does, however, help complement GLP-1 users and their medication, acting as a \u201cbehavior engine\u201d that helps sustain routines after the meds stop. <\/p>\n
Although the coaching premise of the app has remained unchanged, the rise of LLMs has been a boon to personalization. \u201cAI has changed both the product and the model,\u201d he continued.\u00a0<\/p>\n
\u201cEvery dialogue, every logged meal feeds a closed\u2011loop learning system that updates each person\u2019s profile and improves our cohort\u2011level models,\u201d he said. \u201cWith each iteration, Avo becomes more accurate and more proactive.\u201d\u00a0<\/p>\n
Prytkov said that HartBeat approached the company after it launched Avo two years ago. The firm already had a few health investments under its belt.<\/p>\n
\u201cAt the time, we weren\u2019t looking for investors, but HartBeat Ventures felt like an amazing fit for us, so we agreed,\u201d he said, adding that the app already had the metrics, profitability, and traction. Others in the round include the private credit firm Liquidity.\u00a0<\/p>\n
Prytkov believes users, meanwhile, have taken to the app because it doesn\u2019t feel clinical to them. He said virtual wellness has become the \u201cdefault front door\u201d for weight management as it\u2019s proven affordable and accessible. Next, he wants to expand his company\u2019s GLP-1 companion features and also launch specialized women\u2019s health and midlife programs.\u00a0<\/p>\n
Eventually, he plans to expand beyond weight loss and make a health app that can help with sleep, stress, and movement.\u00a0<\/p>\n
\u201cOur vision is to become the Duolingo of health,\u201d Prytkov said. \u201cThe goal is simple. Become the go-to fun health companion people use every day, and the most effective way to build healthy habits.\u201d\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"Mike Prytkov said he knows what it\u2019s like to let stress take over one\u2019s life.\u00a0 While building his…\n","protected":false},"author":2,"featured_media":173415,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[84,4203,77641,56,54,55,7268],"class_list":{"0":"post-173414","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-entrepreneurship","8":"tag-business","9":"tag-entrepreneurship","10":"tag-hartbeat-ventures","11":"tag-uk","12":"tag-united-kingdom","13":"tag-unitedkingdom","14":"tag-wellness"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/173414","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=173414"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/173414\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/173415"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=173414"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=173414"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=173414"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
