We're excited to announce our investment in Pluralis Research, a company advancing "Actually Open AI" through decentralized, collaborative model training. USV and CoinFund co-led the $7.6M seed round, with Variant, Topology Ventures and others participating. Today's AI landscape offers limited options: either use commercial APIs or "open source" models from tech giants. Neither approach fully unlocks the potential for broad participation in AI development. Pluralis enables collaborative training of frontier AI models across distributed nodes with standard internet connections - a radical shift from today's approach requiring high-end hardware in centralized data centers. A key innovation is that models remain within the protocol with no single entity able to extract the full weights. Models are "protocol-owned," with usage revenue distributed to all contributors. This inverts the current "open source" paradigm in AI - instead of obscuring architecture and data while releasing weights, Pluralis opens the full training process while preserving economic interests for contributors. The implications are substantial: preventing power concentration, allowing expertise (not just capital) to drive development, and potentially marshaling compute resources that rival or exceed what even the largest tech companies can assemble. As Albert Wenger recently argued: "The safest number of ASIs is 0. The least safe number is 1. Our odds get better the more there are." Pluralis enables exactly this distributed development and governance of frontier AI. Led by Alexander Long and a team of AI PhDs from Amazon, Oxford, and other leading institutions, Pluralis is developing pioneering techniques to make decentralized model training and protocol-ownership a practical reality. With this funding, they'll continue developing core technology while building their network of compute contributors. First collaborative training runs expected in coming months. We believe Pluralis represents an important step toward more open, collaborative and economically sustainable AI development. Learn more at pluralis.ai. https://lnkd.in/eNrJknwZ

Decentralized training is one of the most critical innovations to pay attention to in the convergence of crypto and AI. It’s why we’re excited to announce we’ve led Pluralis Research’s pre-seed round and teamed up with Union Square Ventures to co-lead its $7.6M seed round. Decentralized training presents a new path forward to developing large scale, open source models that are trained and served over distributed compute networks. However, there’s a consensus view that it’s infeasible in practice due to the communication intensity of training, where latency issues from low bandwidth connections between nodes in a distributed network make training much less efficient than the status quo of centralizing resources to produce the highest efficiency training setup. We disagree. Pluralis Research is working at the forefront of decentralized model training with the goal of creating a global compute network capable of training and maintaining state-of-the-art foundation models. This type of network has a few interesting properties: 1) its models are sharded across multiple network nodes 2) the model weights are unextractable by any single node 3) it is elastic, allowing nodes to freely join and drop from the network 4) it is byzantine tolerant of malicious actors 5) it can support consumer GPUs Behind Pluralis is Founder and CEO Alexander Long, PhD in machine learning and former Amazon researcher. Alex is one of the sharpest minds in DeAI and has assembled a team of the brightest ex-FAANG research scientists working on the cutting edge of decentralized training. We’re honored to be backing founders like Alex and have never been more ready to empower the future of decentralized training.

After doubling to serve 200,000+ assets across 80 countries in 2024, Zeitview is on a mission to inspect and protect the world’s critical infrastructure. With this capital, we will double down on investment in our visual AI, Insights software platform, and global footprint to support our customers across their assets, throughout their lifecycle, anywhere in the world. Our customers are accelerating the energy transition, ensuring we stay connected, and keeping the lights on for families and businesses all over the world. We can't imagine a more fundamental, urgent, important problem to help solve!!

Thrilled to finally be able to share the news of our Series C round with new investor Neurone joining Union Square Ventures and Battery Ventures to support our global expansion. Viam stands apart in our ability to bring AI into the real world. Our platform simplifies, and dramatically speeds up, a company’s ability to improve existing systems and processes, build new products, and spin up new business lines, all by making use of technology and data likely already in hand. Read more of my perspective on what the funding means for us in this post. And of course, thanks to the incredible Viam team for all of your hard work in helping to make today happen.?https://lnkd.in/ejDNHWY4

I've attended a lot of engineering meetups and demo nights in my 15-year career in tech. But last night was the first time I've ever demoed or spoke live about my process as a builder. At the?AI Engineering Meetup?hosted by?Tribute Labs?and held at Union Square Ventures, I led a 25-minute workshop on my process for building an AI-native business, in an AI-native way. Naturally, I had to write about it. In the presentation (affectionately named "Cowgirl Coding," I discuss how I built (and more important, how I iterate and improve upon) MuseKat, an interactive learning app that helps parents and kids explore museums through customizable audio stories. I share what my current "AI Tech Stack" looks like for various part of my prototyping and building process. I also shared a work-in-progress "learning framework" for a theory I've been developing about how our individual learning styles shape how we learn, apply, and problem solve with AI. Finally, I did a live demo of debugging with no-code AI tools. I'm so excited about the power and possibilities unlocked by this era of "anyone can code" and I'd like to give this presentation again, next time for an even less technical audience. If you'd like to team up or collaborate on an event or program, please reach out, and let's make it happen! https://lnkd.in/ekERTnkK #AI #nocodecoding #technology #startups

Yesterday we hosted our Silicon Valley Bank February Fundraising Workshop at Union Square Ventures. Andy Weissman is one of my favorite investors b/c I love the way he thinks, marrying creativity, music, and philosophy together in a world that over indexes on numbers and dollars. It's rare to find an investor who embodies liberal arts thinking with generating alpha. Andy shared his personal investing philosophy, AOL operating experience, and the USV mindset to long term partnerships with founders. I really admire how USV has stayed intentionally disciplined and small as a wildly successful fund through the years. I first came across USV working at Tumblr. We use to do our product offsites out of their old office on 19th and Broadway. Overtime, I got to know the team there and really appreciated how they support product-driven founders and the NY tech market in bespoke ways. What makes USV special? They are a thesis-driven fund that values writing and sharing artefacts of their partners' thinking on deal decision-making. You can find every investment memo online! You can truly dive deep into each of their partners' brains through their writing on their website. With the advent of AI, USV has also added an AI Librarian to the firm, testing different AI tool prototypes that can help share the firm's weekly discussions and learnings. Check out their latest Librarian prototypes here: https://x.com/usvlibrarian
