Web3AI Agent Platform Neuramint Completes $5 Million Seed Round Financing

April 29: NVIDIA officially launched Nemotron 3 Nano Omni, the latest addition to its Nemotron 3 series. The model integrates unified multimodal reasoning into a single, efficient open-source system. NVIDIA explains that agentic systems typically need a single perception-to-action loop spanning screens, documents, audio, video, and text—but they still rely on fragmented model chains: separate visual, audio, and text technology stacks. This boosts reasoning hops and orchestration complexity, driving up costs while eroding cross-modal contextual consistency. Nemotron 3 Nano Omni is designed to replace this fragmented visual-language-audio (VLA) stack, serving as a multimodal perception and context sub-agent within agentic systems. On accuracy, the model topped the document intelligence leaderboard and led in video and audio understanding rankings. Against the open industry benchmark MediaPerf for video understanding, it delivered the highest throughput across all tasks and the lowe

April 29 — LookOnChain data shows a BIT-affiliated whale (who previously netted over $59 million in profits) is ramping up their ETH long positions, now holding 63,000 ETH ($143.5 million) across three wallets.

On April 28, the Over Foundation announced it has shuttered all Over Protocol infrastructure and services—including OverWallet, OverNode, OverFlex, RPC nodes, a block explorer, and related APIs—with no plans to resume operations. Over Protocol is a Layer 1 mainnet; though designed to be decentralized, it will likely struggle to operate smoothly after the foundation cuts its services. Block production hinges on whether independent validators keep running the open-source client, a scenario the foundation says it cannot guarantee. Earlier this year, reports highlighted a wave of crypto project shutdowns, with Dmail, Tally, and Step Finance among the firms ceasing operations amid falling user activity, tighter funding access, and rising costs. Industry insiders note that relying on token fundraising has proven ineffective: crypto projects lack clear liquidation and restructuring frameworks, making it hard to coordinate creditor rights or revive operations during financial distress

April 28th — AI recruitment startup Dex has closed a $5.3 million seed round of funding, led by Notion Capital, with participation from a16z Speedrun, Concept Ventures, and angel investors including OpenAI alumni and industry peers. The round pushes the company’s total funding to $8.4 million. Founded by former Atomico advisor Paddy Lambros, Dex bills itself as an “AI talent agent” focused on high-end technical talent: AI researchers, software engineers, and the like. To date, over 15,000 engineers have registered on the platform, which serves 50+ tech firms including ElevenLabs and Synthesia. Dex’s tool interacts with job seekers via voice or text, builds candidate profiles using models from OpenAI, Anthropic, and other providers, and connects them directly to employers via a matching engine. Unlike traditional HR software vendors, Dex does not sell software to companies; instead, it charges a 20%–30% fee of a candidate’s salary upon successful placement. The startup reports

On April 28, Coinbase announced it will list Virtuals Protocol (VIRTUAL) for spot trading starting April 29. Should liquidity conditions be met and trading supported, the VIRTUAL-USD trading pair will launch at 9:00 AM Pacific Time or later.

**Oakland, Calif. — April 28:** Elon Musk has arrived at the Oakland Federal Court to attend a hearing in his lawsuit against OpenAI. As previously reported, Musk accused OpenAI co-founders Sam Altman and Greg Brockman of inducing his $38 million 2015 investment by promising to keep the organization nonprofit. OpenAI later converted to a for-profit structure. Musk is seeking up to $134 billion in damages, stating all compensation would be returned to OpenAI’s nonprofit arm. He also seeks the removal of Altman and Brockman from their roles and a reversal of the for-profit conversion. Presiding Judge Yvonne Gonzalez Rogers is overseeing the case; the liability phase is expected to last through mid-May, with both sides scheduled to testify in court.
