Taranjeet Singh<\/a> (pictured above, right) has launched six companies, with some failing and others seeing varying degrees of success. His seventh, Mem0<\/a>, could be his defining one.<\/p>\n

The startup starts with the premise that large language models can\u2019t remember past interactions the way humans do. If two people are chatting and the connection drops, they can resume the conversation. AI models, by contrast, forget everything and start from scratch.<\/p>\n

Mem0 fixes that. Singh calls it a \u201cmemory passport,\u201d where your AI memory travels with you across apps and agents, just like email or logins do today. The YC-backed startup, launched in January 2024, has raised $24 million ($3.9 million in previously unannounced seed funding and a $20 million Series A).<\/p>\n

AI-focused early-stage fund Basis Set Ventures led the Series A, with participation from existing investors Kindred Ventures and Y Combinator, as well as new backers including Peak XV Partners and the GitHub Fund.<\/p>\n

Notable angels include Dharmesh Shah (HubSpot), Scott Belsky (ex-CPO Adobe), Olivier Pomel (Datadog), Thomas Dohmke (ex-CEO GitHub), Paul Copplestone (Supabase), James Hawkins (PostHog), Lukas Biewald (Weights & Biases), Brian Balfour (Reforge), Philip Rathle (Neo4j), and Jennifer Taylor (former president, Plaid).<\/p>\n

Having several leaders who helped shape the modern software ecosystem bet on Mem0 (pronounced \u201cmem zero\u201d) underscores its promise, and the traction from the four-person team backs it up.<\/p>\n

So far, the open source API, which claims to be the most widely adopted memory framework for AI developers, has surpassed 41,000 GitHub stars and recorded over 13 million Python package downloads. In Q1 2025, Mem0 processed 35 million API calls. By Q3, that number jumped to 186 million, growing roughly 30% month over month.\u00a0<\/p>\n

Beyond open source adoption, more than 80,000 developers have signed up for its cloud service. Mem0\u2019s cloud API now handles more memory operations than any other provider and serves as the exclusive memory provider for AWS\u2019s new Agent SDK.<\/p>\n

In early 2023, Singh was still in Bangalore, India. He started his career as a software engineer at Paytm, one of India\u2019s most valuable startups, before becoming Khatabook\u2019s first growth engineer. He quit in late 2022, just as the ChatGPT wave was about to crest, and built one of the first GPT app stores, which scaled to over a million users.<\/p>\n

That experience led him to create Embedchain, an open source project that lets developers index, retrieve, and sync unstructured data. As the project took off, earning more than 8,000 GitHub stars, Singh sent over 200 cold emails to founders, investors, and engineers in Silicon Valley.<\/p>\n

\u201cI reached out to almost every famous tech entrepreneur that you might have heard of and was quite persistent. Some of them responded, and after hearing us out, scheduled us to fly from Bangalore to San Francisco within 36 hours,\u201d Singh said.\u00a0\u00a0<\/p>\n

Once in the U.S., Singh reconnected with his longtime friend and now co-founder and CTO, Deshraj Yadav, who had led the AI Platform at Tesla Autopilot. Together, they had previously built EvalAI, an open source Kaggle alternative that grew to 1.6K GitHub stars.<\/p>\n

While experimenting with Embedchain, the duo launched a meditation app inspired by Indian yogi Sadhguru. The app went viral in India, but Singh says users kept sharing the same feedback: \u201cHey, I\u2019m on this meditative journey, but the app doesn\u2019t remember that.\u201d So they pivoted from Embedchain to Mem0 to solve that problem.<\/p>\n

The idea of memory for AI isn\u2019t new, but it\u2019s quickly becoming a critical battleground. OpenAI, for instance, began testing long-term memory features in ChatGPT in early 2024, and its CEO, Sam Altman, has hinted that persistent memory will be central to OpenAI\u2019s upcoming hardware device. Other AI labs are also launching experimental memory systems for their agents.<\/p>\n

Singh argues that while big AI labs are building memory systems, they have little incentive to make them portable or interoperable. \u201cMemory is becoming one of their key moats now that LLMs are getting commoditized,\u201d he said.<\/p>\n

He explains that while consumers can enjoy persistent, personalized experiences in ChatGPT, developers who want to build applications \u2014 say, a finance companion that remembers a user\u2019s trading history \u2014 need an open, neutral solution like Mem0.<\/p>\n

\u201cWe want developers to offer day-one personalization through a shared memory network,\u201d Singh said. \u201cThink of it as Plaid for memory. That\u2019s act two. For now, we\u2019re laser-focused on building the best memory product possible.\u201d<\/p>\n

Mem0\u2019s framework lets developers store, retrieve, and evolve user memory across models, applications, and platforms. It\u2019s model-agnostic, compatible with OpenAI, Anthropic, or any open source LLM, and integrates directly with frameworks like LangChain and LlamaIndex.<\/p>\n

Developers use Mem0 to create applications that grow smarter with every interaction: therapy bots that recall past conversations, productivity agents that remember personal habits, and AI companions that adapt over time. Customers range from indie developers to enterprise teams building copilots and automation tools.<\/p>\n

\u201cWe backed Mem0 from its earliest days \u2014 even before YC \u2014 because memory is foundational to the future of AI,\u201d said Lan Xuezhao<\/a>, founder and partner at Basis Set Ventures. \u201cWe\u2019re doubling down as the team continues to tackle one of the hardest and most important infrastructure challenges: enabling AI systems to build lasting, contextual memory.\u201d<\/p>\n

Other early-stage startups in the memory space include Supermemory<\/a> (whose founder briefly worked at Mem0), Felicis-backed Letta<\/a>, and Memories.ai<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"Taranjeet Singh (pictured above, right) has launched six companies, with some failing and others seeing varying degrees of…\n","protected":false},"author":2,"featured_media":533721,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3163],"tags":[323,172660,158945,1942,172661,172662,53,16,15],"class_list":{"0":"post-533720","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-artificial-intelligence","8":"tag-ai","9":"tag-ai-apps","10":"tag-ai-memory","11":"tag-artificial-intelligence","12":"tag-mem0","13":"tag-memory-layer","14":"tag-technology","15":"tag-uk","16":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115453026817466632","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/533720","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=533720"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/533720\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/533721"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=533720"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=533720"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=533720"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
