Unconventional AI Leads Funding Flurry With $475 Million Seed Round

In this week’s artificial intelligence (AI) startup funding news, fresh capital flowed into companies focused on computing, operational efficiency and domain-specific AI tools.

As reported by Bloomberg, the largest deal came from Unconventional AI, which raised $475 million in a seed round at a $4.5 billion valuation as it builds a novel computer optimized for AI workloads. The company was founded two months ago by former Databricks head of AI Naveen Rao and aims to rethink the architecture of AI computing by drawing inspiration from biology and analog physics.

According to the report, Unconventional AI is designing systems that prioritize energy efficiency by exploring semiconductor-level physics, analog computational approaches and new ways to scale compute without hitting power constraints. The $475 million represents the first portion of a fundraising effort that may reach $1 billion as the company prototypes multiple architectures in search of a paradigm that can scale more efficiently than today’s GPU-based systems.

Investors include Andreessen Horowitz, Lightspeed Venture Partners, Lux Capital, DCVC, Jeff Bezos, Databricks and Rao himself, who invested $10 million on the same terms as outside backers.

Training and Support Tools Attract Interest

Yoodli announced a $13.7 million fundraise and the launch of its AI Roleplays product, an expansion of its communication-skills platform. The company said the new category is designed to help users rehearse difficult workplace conversations through structured AI simulations.

The model generates realistic conversational scenarios across sales, coaching, interviewing and feedback settings, allowing users to practice and refine delivery. Yoodli noted that organizations are increasingly turning to AI-based experiential training to improve managerial readiness and customer-facing communication. The financing brings Yoodli’s total capital raised above $20 million and will support expansion into corporate learning and global distribution.

In Europe, Parloa, an AI-powered customer-service automation platform, is preparing a new fundraising round that could value the company at more than $2 billion. Parloa aims to secure about $200 million to scale its conversational-AI stack, which helps enterprises automate call-center workflows, routing, self-service and agent assistance.

The potential round reflects the accelerating demand for AI systems that can manage high-volume, multi-language customer interactions. Parloa has leaned heavily into enterprise-grade reliability and integrations, citing strong traction with retailers and logistics providers that are turning to automation to reduce support costs and improve service levels. If completed, the round would place Parloa among Europe’s highest-valued customer-experience AI companies.

Vertical AI Firms Extend Their Momentum

Another major transaction came from Harvey, which announced that Andreessen Horowitz led a $160 million investment as the legal-tech firm continues expanding its AI platform for law firms and corporate counsel. Harvey builds AI systems that support large-scale document review, contract analysis, research and drafting.

The company said the funding will accelerate its work on structured reasoning and enterprise controls, areas that matter for legal workflows that require auditability, data security and consistent outputs. Harvey’s raise reinforces investor confidence in vertical AI systems built for expert tasks rather than broad consumer use.

ChemLex, a startup applying AI to chemical research and discovery, announced new funding and the release of its ChemLex 1.0 platform. The company’s technology automates chemical structure generation, prediction and analysis, aiming to shorten discovery cycles for industrial chemistry, materials science and pharmaceuticals.

ChemLex said the new capital will be used to scale scientific-grade models that can interpret molecular data, run simulations and generate synthesis pathways. The firm highlighted that demand is growing for AI tools that can augment R&D teams facing rising complexity and global competition. The release of ChemLex 1.0 positions the company within a rising class of scientific-AI startups designing foundation models tailored to chemistry and biology rather than text or images.

Flex, a U.S. FinTech serving mid-sized businesses, raised $60 million in a Series B round reported by PYMNTS. Portage Ventures led the financing, which lifts Flex’s valuation to roughly $500 million. The firm offers an AI-native financial platform that combines business banking, payments, private credit, treasury and personal-finance tools for owners of mid-market companies.
