- Naoma
Participated · Seed · Feb 2026
Naoma is a San Francisco-based startup building an interactive AI platform that replaces traditional sales scheduling with real-time, personalized demos delivered through voice and video avatars. The solution cuts demo wait times from more than 24 hours to roughly 10 seconds, enabling companies to engage the 98% of B2B website visitors who typically abandon the funnel before speaking with a representative. Led by CEO and co-founder Dmitry Zakharov, the company positions its technology as a way to boost lead capture and conversion rates. Naoma plans to use its newly raised capital to accelerate product development and scale customer acquisition initiatives. The emphasis is on refining the AI demo experience and expanding market reach. To date, the company has secured $440,000 in outside capital through its pre-seed round, representing its first disclosed financing.
- Techarena
Participated · Seed · Feb 2026
Naoma has developed a conversational AI platform that embeds live, interactive video demos directly into a company’s website or product account, eliminating the need for prospects to wait for a human-led Zoom or Meet session. Its AI avatars present, answer questions in multiple languages, qualify leads on the fly, and automatically update CRM records, giving prospects a tailored demo experience in about ten seconds. The six-person team, co-founded by Dmitry Zakharov and Dima Ivanouski, draws on prior experience in high-velocity SaaS sales to address the conversion drop-off caused by delayed or static demos. Naoma differentiates itself from incumbents such as Navattic, Reprise, and Walnut by offering live, AI-driven video rather than pre-recorded walkthroughs. With $440,000 in new capital, the company is expanding its engineering team, enhancing avatar realism, and launching pilot programs with B2B software vendors. Management ultimately envisions running millions of demo sessions annually within the next four to five years, positioning the product as an always-on layer in modern SaaS buying journeys.
- Cell-En
Led · Seed · Oct 2025
Cell-En is building a microbial fuel cell system that functions as a “wherever, whenever” off-grid power source by harvesting electrons generated when microbes break down organic waste. The platform, branded as “Cell-En Technology,” solidifies the power-generation core to boost output efficiency and enables local procurement of both microbes and nutrient feedstocks, supporting energy self-sufficiency while simultaneously reducing food and agricultural waste. The company envisions deploying its units to enhance community resilience against climate-related disasters by providing phase-free, sustainable electricity independent of existing grids. With the proceeds from its latest financing, Cell-En will scale the device for outdoor demonstrations, advance proofs of concept with corporate and municipal partners, pursue joint research with academic institutions, and expand hiring. Founded in August 2023, the startup’s microbial power technology was selected in July for the Tokyo Metropolitan Government’s FY2025 Next-Generation Renewable Energy Social Implementation Program. Cell-En has raised ¥150 million to date through a blend of equity and subsidies, and it is currently focused on maturing its prototype rather than generating revenue.
- Freename
Participated · Series A · Jul 2025
Freename combines traditional DNS and blockchain capabilities to enable domains that resolve to IPs, wallet addresses, smart contracts, and on-chain reputations. Its platform supports major blockchains such as Polygon and Solana and works through standard browsers via a proprietary resolution protocol for Web2–Web3 interoperability. The company offers collision management to resolve duplicate domain names across blockchains and lets users create and monetize custom top-level domains. Freename aims to improve blockchain metadata and bridge conflicts between IP and wallet addresses to unify digital identity ecosystems. It recently closed a $6.5M Series A and plans to use the funds to drive product innovation, expand globally, and further unify Web2 and Web3 identity systems. The company emphasizes a strong regulatory posture and intends to enable regulated handling of wallet-address resolution while preparing additional products for release. Freename provides infrastructure for Web3 domains, allowing users to register and mint TLDs and SLDs on multiple blockchains for uses such as crypto payments, web2 and web3 email, browsing traditional sites, and building decentralized websites. The platform lets participants earn royalties and offers options to trademark Web3 TLDs and domains to protect identity. Freename has issued more than 5,000 Web3 TLDs to date and is growing its team and community. The company is moving toward interoperability to converge Web3 with Web2 and improve the user experience. Management says the recent seed funding will help accelerate those interoperability and product goals. Freename was founded in 2021 in Wollerau (Kanton Schwyz).
- Katara
Led · Seed · Aug 2024
Katara builds an AI-agent workflow automation platform and marketplace that lets clients deploy and combine autonomous assistants to automate fragmented DevX tasks. The platform leverages a mix of traditional ML/NLP alongside foundational models and generative AI, using a human-in-the-loop approach to balance efficiency and safety. It unifies community and developer management, analytics, and content platforms to streamline onboarding, content creation, and repetitive Q&A workflows. Early launch partners AVAIL Protocol, Hivemapper, and Filecoin have reportedly saved over 8,700 hours annually using the platform. Katara plans to scale globally and expand its offering beyond web3 to include web2, AI, and open-source platforms while continuing development of its AI-agent marketplace. Financially, the company has raised $2.6 million in combined pre-seed and seed rounds.
