Bitstack

All things money, with better money

Bitstack is building a new neobank powered by crypto. Bitstack has gone from a simple product that turns your spare change into bitcoin to a bitcoin-native neobank that is bringing a better way to manage all things money, with better money. We believe getting started with Bitcoin should be simple, fun and accessible to everyone. Bitcoin is an unparalleled financial alternative: a radically new way to transact and store value all around the world. It is a new kind of currency that isn't centrally controlled by any business, government or bank and that cannot be debased. Bitcoin will redefine the future of finance, from payments to savings, and wealth preservation. It is the first open and borderless monetary network with a fixed supply of 21 million, making bitcoin the most scarce financial asset ever.

Blacksmith

The fastest way to run your GitHub Actions

Blacksmith helps companies run their continuous integration (CI) up to twice as fast, at half the cost. We do this by running their CI on high performance gaming CPUs. - Engineering productivity is often marred by slow CI that grows quadratically with the size of the engineering organization. - On top of this, companies pay high markups to run CI on the hyperscalers. - Consequently, companies have to run their CI on spot instances to keep costs in check. Since spot instances can get pre-empted at any point, running CI reliably on them requires [significant engineering investment](https://www.rippling.com/blog/how-rippling-used-spot-instances-to-save-and-scale-ci-cd). Blacksmith offers CI compute that is more performant, cheaper, and reliable. With Blacksmith, companies do not have to think about CI as they scale. We are starting with GitHub Actions - today's most popular and fastest-growing CI system. With a one-line change, companies can run their CI up to twice as fast on our high-performance hardware. In addition to this, Blacksmith provides colocated warm caches along with optimizations for common CI workloads (like building and pushing Docker images). Aayush, JP and Aditya have gained deep systems and product knowledge from their time at Cockroach Labs and Faire respectively. Both these companies, with several hundred engineers, were spending in the order of millions of dollars on their CI. Yet they were riddled with slow CI and actively seeking out cheaper and faster alternatives. Blacksmith offers exactly this alternative, at a time where being lean is table-stakes for most companies.

Blank

Instagram for Generative AI

AI is the most powerful creative tool ever invented—but using it today is a total nightmare. Your average user doesn't care which model is being used, what LoRA's are, or have patience to deal with Discord slash commands or complex designs. What the last 20 years of social media have taught us is that users want an easy way to create, discover, and share amazing content with friends. We’re also quickly learning that the models aren’t the moat. The real value lies in the consumer app that can make AI engaging, social, and accessible to everyone. And that’s exactly what we’re here to do. Blank makes creating with AI effortless, social, and fun. We package powerful new technologies in a familiar and approachable UI, making AI accessible to anyone.

Blank Bio logo

Blank Bio

RNA-based AI for better drugs and smarter clinical trials.

Blank Bio builds foundation models that understand RNA, the language of life. Our model powers applications across the entire R&D pipeline, from designing better drugs to running smarter clinical trials. Our first model is state-of-the-art in mRNA property prediction. It simulates costly experiments, helping partners design more effective mRNA medicines faster and cheaper. Our open-source models are being used by Sanofi & GSK. We’re also collaborating with the Arc Institute to bring our RNA embeddings into the next generation of virtual cell models. mRNA design is just the beginning. As the model improves, we’re extending to applications like target ID, novel biomarker discovery, patient stratification, and more. We’ve spent decades applying machine learning to biology across academia (PhDs at the University of Toronto) and industry (Recursion, Deep Genomics, Amazon). Contact us to learn more: founders@blank.bio

Blaxel logo

Blaxel

AWS for AI Agents

Blaxel is a cloud infrastructure to power AI agents. Our platform gives AI companies the toolbox and infrastructure to build and deploy agents efficiently. Billions of agents, tools, and models will transform how we work in the coming years. Traditional cloud providers weren't designed to handle them—their one-size-fits-all architecture holds them back. We fixed that with Blaxel. What is it? A complete computing platform with: - all services for developers to fast-track deploying agents without reinventing the wheel — like framework-agnostic serverless deployments, an AI gateway for model routing and fallback, and custom MCP server hosting. - a flexible low-level API for builders to ship really performant agentic AI using our backbone infrastructure — using services like sandboxed VMs usable by agents, a programmable global gateway, and a 20ms-latency serverless compute engine. - and a seamless developper experience that integrates with their CI/CD, and APIs that can even be consumed by agents themselves!
