Based in Israel, Believer Meats( Future Meat Technologies  prior to November 2022) develops hardware and cell lines for the manufacturing of cell-cultured meat, with the intention of commercializing its manufacturing hardware and techniques.

Believer Meats uses fibroblast cells that can be triggered with small molecules to develop either fat or muscle cells. Fat and muscle cells are cultured in a unique bioreactor that removes the waste material from the media, allowing the company to recycle parts of the media with the aim of reducing feed media input by as much as 50%. The startup replaced FBS with molecules derived from Chinese hamster ovaries (CHO), reducing production costs. The startup has managed to reduce production costs to USD 150/lb for chicken and USD 200/lb for beef. According to Founder Yaakov Nahmias, a refrigerator-sized bioreactor has the capacity to produce approximately half a ton of muscle and fat every 14 days. In May 2021, the startup reduced the cost of cell-cultured chicken breast by 50%—USD 4 per quarter-pound serving from USD 7.50 in February 2021. In December 2021, the company further reduced the cost of cultivated chicken breast to USD 1.70, surpassing its 18-month projection and speeding up its goal to achieve price parity with animal counterparts. It also had plans to launch its product in the US by 2022.

In June 2021 , Believer Meats opened what the company claimed was the world's first “industrial” cell-cultured meat facility. The facility has a production capacity of 500 kg of cultured meat per day (equivalent to around 5,000 hamburgers) and will produce cultured chicken, pork, and lamb, with beef production expected to follow. The company’s first product was expected in 2022 as a blend of 45%–60% cell-cultured chicken and/or lamb and 40%–55% plant-based meat. Besides the US and Europe, Believer Meats planned to debut in Asia, with China and India its primary markets, and partnered with Charoen Pokphand Foods to develop cultivated meat products for Asia. In August 2022 , the company announced it has developed what it claims to be the world’s first cultivated lamb.

In its latest funding round in December 2021, the company raised USD 347 million in a Series B recording the largest investment in cell-cultured meat at the time. The round was co-led by ADM Ventures, while funds were to be used to accelerate its production plans in the US.
