The existing infant formulas are largely based on cow milk which naturally lacks several essential components of human milk like lactoferrin, HMOs etc. which are critical for the nutrition of the baby. Recently there was one of the biggest recalls in history of infant formula in Dec 2025, with a similar recall in US in 2022 which led to sudden shortage of infant formulas and left parents extremely worried and vulnerable. To circumvent such incidents we need more clean-label innovation in this space to create better and more robust solutions for infant nutrition.\n\n> **_What and How? - Harnessing Biology Responsibly!_**\n\n![uploaded image](/media/?type=post&id=98944&key=user_uploads/215532/88fc5eaf-d775-43a4-86a0-104692179c41)\n\n🚀 🚀 **Huge** **Breakthrough** - **We have been able to secrete Real Human Milk in lab!!!** We have validated all proteins by independent third party testing and have also tested for fats and carbohydrates to create a basic version of real human milk. By using mammalian cell culture we have designed a system to produce human milk in lab with a macronutrient focus currently. We are a Stanford, Rice University and IIT Delhi alumni team with backgrounds across biotechnology, business and innovation, determined to make a huge impact by using technology and leveraging recent advances in understanding of biological systems. This breakthrough leverages our extensive work on cow milk ([Forbes](https://www.forbes.com/sites/daphneewingchow/2025/02/24/first-lab-grown-whole-cows-milk-to-debut-in-the-us/)) as we add this new product to our pipeline - UnReal Human Milk.\n\n> **_More Exciting Stuff! - Why should human adults drink cow’s milk and not human milk?_**\n\nUntil now we had no way to mass produce human milk so we resorted to drinking cow milk since we could keep the poor cows in captivity to produce as much milk as needed. But now with our standardised scalable approach to creating human milk maybe we can move everyone across the planet from drinking cow milk to human milk. Think human milk ice-creams and human milk cheeses - the opportunities are huge!\n\n![uploaded image](/media/?type=post&id=98944&key=user_uploads/215532/0b9233c8-9808-4043-83e6-e350806da38b)\n\n> **Reach-out to us** at [**sohail@brownfoods.in**](mailto:sohail@brownfoods.in) if you want to collaborate, invest or partner with us on this journey.\n\nThank you!\n\n![uploaded image](/media/?type=post&id=98944&key=user_uploads/215532/db9850e5-7d88-42fb-9ea4-871d78b1dd1f)\n\n", "url": "https://www.ycombinator.com/launches/Pjs-brown-foods-real-human-milk-without-any-breast-feeding", "votes": 19, "created_at": "2026-03-19T20:34:23.580Z" } ] }, { "id": 25399, "name": "Invert", "slug": "invert", "former_names": [ "Invert Bio" ], "small_logo_thumb_url": "https://bookface-images.s3.amazonaws.com/small_logos/1e1a589d7f48cf8cc7fb3658ec8dea0855d526a0.png", "website": "http://www.invertbio.com/", "all_locations": "San Francisco, CA, USA; Remote", "long_description": "We build software to manage, analyze, and optimize bioprocessing data.
