Co-Founder ꩜Substrate

Substrate is live! After nearly a year of development, really honing the developer experience and performance tuning a very unique runtime environment, we're finally releasing what we feel is by far the best way to run multi-inference workloads (e.g. agents, multimodal text, json, image, audio, embedding pipelines, etc). Substrate lets you use a ergonomic SDK (we really obsessed over the abstractions and typeaheads) to describe precise and complex relationships between AI tasks. And—importantly—it's connected to a backend specifically designed to run these graph workloads as efficiently as possible (optimized models, auto batching, insanely fast inter-node RPCs). Given the current state of "AI" models, we really believe that this pattern is the most effective for building capable, reliable, legible, extensible features with AI that go far beyond chatbots. We need both heuristic models like LLMs as well as normal symbolic computation, and a flexible/scalable way to coordinate these two modalities. We've already seen organizations like Substack building some super interesting pipelines that they can easily understand and iterate on, that just work at scale. It's still early in a much more ambitious vision for us, but we think this V1 is not only ready but already a meaningful improvement to many implementations. Reflecting on the last year, I feel so much gratitude for the team that I'm working with: Ben Guo, Liam Griffiths, Rishabh Parikh, 💭 Kyle Pitzen, Chris S., (& Hanwen Wu soon!). With this launch, we're announcing an $8M Series Seed led by Lightspeed (Nnamdi Iregbulem+Guru Chahal) with participation from many others. Feeling a ton of appreciation for the folks that took a bet on us or have lent their time and advice: South Park Commons (Ruchi Sanghvi+Aditya Agarwal), Craft Ventures, Red Swan Ventures (Andy Dunn), Lorimer Ventures, Chris Best, Jairaj Sethi, iqram and the immigrant groove, Andrew Kortina, Guillermo Rauch, Immad Akhund, Sam Lessin, William Gaybrick, Gokul Rajaram, Jana Messerschmidt, Shreyas Doshi, Matthew Hartman, Mike Cohen, Sabrina Hahn, Anne Lee Skates, Shreyans Bhansali, Julian Connor, Namrata Patel + many many others. https://lnkd.in/eHq8KUkA
