Phosphor enables the development of the built world (e.g. from real estate to energy projects) to be managed agentically by building programming languages and observability primitives (like version control) on top of a hypergraph.
Our primary technical bet is that if you capture annotated "diffs" of user information with the appropriate annotation, you can create path-dependence to train AI models in an AlphaGo like context. By doing so, we achieve agentic experiences for markets that have never even had an opportunity to imagine what life would be like with basic observability.
Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.
We're in stealth, but recently venture-backed by one of the best deeptech funds in the market. We're hiring for a few roles at the senior/staff levels: 1. HCI Engineer - You're a prosemirror wizard who probably follows Ink & Switch or the UCSB HCI lab on Twitter; front-end/rich-text/typescript focused; lots of architectural/sync engine work 2. Systems/Compiler Engineer - We design and build dev tools for languages we create that compile into various graph representations. These range from financial modeling calcs (which need to go very fast to support a seamless UX), to computable representations of legal agreements. Extra points if you've worked with hypergraphs. This in Rust but we're exploring a few other languages.

What we're building:
* A general-purpose automation platform for healthcare ops, powered by LLMs
* A system that reads unstructured documents, fills out payer forms, and explains rejections
* Tools to automate patient discharge planning in hospitals
* A foundation for making AI in healthcare safe, observable, and human-in-the-loop
What we're looking for:
* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship
* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability
* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed

Felt is building a cloud-based geographic information systems (GIS) solution and have hundreds of customers already using it to run their operations, processing terabytes of data. Our team hails from Uber, Google, Meta, CARTO, Mapbox, The New York Times and a few others. If you have used online maps in the past few years, you have used their work. My co-founder and CEO, Sam, is a former YC founder who sold his previous company [1] and I'm an early Uber engineer.
For the first time, we are hiring a product manager that is going to be focused on our growth funnels within our service. This person will own the onboarding journey and help those first-time customers become loyal users. This role comes at a special time where we have launched a brand new version of our SDKs and APIs where customers, especially in large enterprises, can fully integrate Felt into their own tooling [2]
Ideal candidates will have 4+ years of experience focus on growth and onboarding within B2B SaaS and/or PLG companies. They will have a proven track record, own metrics such as time to value, be comfortable owning touchpoints, and designing and running experiments.
As mentioned, this role is the first product role at our fast growing company and will have strong leadership potential. You'll be joining a team that's build groundbreaking tools before, and is on the cusp of doing it again.
We are well-funded with a long runway and a strong revenue funnel already. You can read more about it our first funding here [3], and our announcement here [4]. Our terms are employee-friendly terms such as early exercise, a 10-year exercise window and even a matching 401(k).[5]
If you are interested, please reach out via hello@felt.com and mention HN and the role you are applying to. This role is based in SF Bay Area, in our Oakland office that's right next to the BART station. [6]

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.
We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund. Before that I was a staff software engineer at Lyft, and Adam was CRO at Wunderkind ($100m+ ARR). We've built a powerful voice agent, and are expanding into other parts of the sourcing-to-onboarding flow. We have customers, revenue is growing, and so is our team.
We're currently a team of 3 engineers in NYC (9 people total). We're working on really cool problems with multimodal AI agents (and some really not cool problems like ATS and HRIS integrations). I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity. Recently A16Z mentioned us in the state of voice AI report: https://a16z.com/ai-voice-agents-2025-update/
We're building on LiveKit's agents framework, Python, and NextJS. We're having a lot of fun and having real positive impact on our customers' businesses.
