Adit Singh Joins Mayfield as Infrastructure Partner
Adit Singh, an early investor in chip maker Cerebras and former partner at Foundation Capital, has joined venture firm Mayfield as an infrastructure partner. At Mayfield he will focus on investments in hardware, infrastructure software, cybersecurity and "physical AI," citing the firm's strong semiconductor portfolio. Mayfield manages roughly $3 billion and can write seed checks up to $20 million, a capability Singh said influenced his decision. The move follows Singh's stints co-founding Neotribe Ventures and working at Cota Capital.
Experienced infrastructure-focused investor joining a large VC (Mayfield) may shift funding toward semiconductor, hardware and AI-infrastructure startups; moderate industry relevance rather than industry-shaking.

Peak XV Secures $1.3B to Boost AI Investments in India
Peak XV announced a $1.3 billion raise across new India- and Asia-focused funds, increasing its assets under management to more than $10 billion. The capital will be deployed mainly into India seed and venture funds and an APAC vehicle, with the firm expecting to invest the pool over the next two to three years. Peak XV said it will prioritise investments in AI, fintech, consumer startups and emerging deep tech, and has made more than 80 AI investments to date. The firm split from Sequoia Capital in 2023 and now holds a portfolio of more than 450 companies across fintech, software and consumer internet. Managing director Shailendra Singh emphasised a returns-focused, selective approach and noted the firm is still building its U.S. presence. The raise was announced as New Delhi hosted the AI Impact Summit, where other investors and tech companies, including General Catalyst, OpenAI, Anthropic and Google, were present.
Cognichip Raises $60M to Use AI to Design Chips
Cognichip is developing a deep-learning system to assist engineers in designing semiconductor chips, aiming to shorten multi-year design cycles and reduce development costs. The startup, which emerged from stealth in 2025, said it raised $60 million in a new funding round led by Seligman Ventures; Intel CEO Lip‑Bu Tan participated and will join Cognichip’s board, and Umesh Padval (Seligman) will also join the board. Cognichip says its advantage is a domain-specific model trained on chip‑design data (including synthetic and licensed datasets) and secure procedures to let partners train on proprietary data. The company claims it can cut chip development costs by >75% and timelines by >50% but has not yet produced a chip designed end-to-end by its system and did not name customers. It has demoed the model with students using the open RISC‑V architecture and competes with incumbents like Synopsys and Cadence and startups such as ChipAgents and Ricursive.
Prime Intellect Raises $130M Series A
