Y Combinator-д орсон анхны Монгол founder-тай стартап болоод $2.6 сая доллар босголоо. Манай компани Y Combinator-ын ерөнхийлөгч Garry Tan-ын ангид сонгогдож орсон завшаантай. Өөрийн компаниа удирдаад явахад сурах зүйл ихтэй өдөр бүр урамтай🙂. Бүтээгдэхүүнээ хөгжүүлээд өнөөдөр https://t.co/sdfbJUnFBU
