- Mem0
Participated · Series A · Oct 2025
Mem0 is building a production-grade memory infrastructure platform that lets developers add long-term, context-aware memory to large-language-model agents with only three lines of code. The system stores key information from prior interactions, prunes outdated or conflicting data, and surfaces relevant details when an agent needs them. Adoption has been rapid: the open-source project has amassed more than 41,000 GitHub stars and 14 million downloads, while API traffic grew from 35 million calls in Q1 to 186 million calls in Q3 2025. Thousands of teams, including startups, Fortune 500 companies, and frameworks such as CrewAI, Flowise, and Langflow, run Mem0 in production; AWS selected it as the exclusive memory provider for its Agent SDK. Founded by Taranjeet Singh and Deshraj Yadav and headquartered in San Francisco, the company is positioning itself as the default “memory database” for the emerging agentic software stack. Backers include Y Combinator, Basis Set Ventures, Peak XV Partners, and several leading infrastructure-company CEOs. The new capital will fund continued platform development and expansion of its developer ecosystem.
- Guardrails AI
Participated · Seed · Feb 2024
Guardrails AI offers a wrapper platform for proprietary and open-source text-generating models (including GPT-4) designed to make outputs more trustworthy, reliable and secure. Its open-source codebase is available on GitHub and the company runs a marketplace called the Guardrails Hub where developers submit modular “validators” that probe model behavior; there are about 50 validators available today. Validators range from simple rule-based checks to algorithms that detect hallucinations, policy violations, proprietary-data leakage and insecure code, and can be deployed, repurposed and reused by other developers and customers. The company uses a crowdsourced approach to build reusable guardrails while allowing organizations to customize checks for org-specific risks. Guardrails is not yet charging for services or software and employs a six-person team. The startup plans to use recent funding to expand the team and support additional open-source projects.
