Hi all, I’m Yuriy, founder of Puma.tech. Prev. worked at Cloudant (YC S08), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).
We have 3 products:
1. https://PumaBrowser.com – iOS & Android mobile browser with built in LLMs & Wallets. Private by design. 1m+ downloads.
2. https://PumaAI.com – privacy layer between you and LLM providers.
3. https://PumaClaw.com – (just starting to build) easier way to run and manage your Claws from the phone.
Help building either or all is much appreciated.
Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth

Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.
How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.
Thank you!
We are building a knowledge graph from web data with a first focus on data for go-to-market teams.
We use web data to identify things like org structure, tech stack, and key projects (e.g., GenAI initiatives, cloud migrations). Our product already has strong product-market fit, early revenue, and happy customers — and now we’re ready to accelerate.
Our long-term vision is to become the world's best data vendor. Try the product at sumble.com.
We are a team of 25 with experience at companies such as Google, Meta, Stack Overflow, Rippling, Snowflake, Confluent and Kaggle.
We raised $38.5MM from Coatue, Canaan, Square Peg Capital https://techcrunch.com/2025/10/22/sumble-emerges-from-stealt...
Our team is operating with the special combination of rigor, empathy, and innovation required to fuel a global shift from reactive sick care to preventative, precision healthcare.
Technologies: Express, React, GCP, Terraform, DBT, MySQL, Snowflake

P.S: We have a new role coming up: Staff SWE, Agentic AI. This role will drive the vision and implementation of agentic AI across our engineering, product, and design teams and later our broader company (clinicians, hospitality teams, ...). This is a special role where we're looking for someone with a strong engineering background who is on the frontier of agentic development. Please express interest via email.
Luminate is the entertainment industry’s preeminent data and insights partner, serving as the single source of truth for record labels, film studios, talent agencies, and every part of the music and entertainment ecosystem.
The team's stack is Java w/ Spring, React w/ Typescript, and SQL w/postgres, and snowflake. We use playwright for e2e testing and deploy our infra on AWS.
The team is relatively new (around 3 years old) but is working on an older codebase with plenty of tech debt. Luckily we actually _do_ get time to address our tech debt and take the time to leave our code better than we found it, so it's getting better all the time.
We have an oncall rotation but getting paged is pretty rare.

We're building the AI-powered platform for enterprise data. Automatically analyse data quality, automatically fix and enhance data, and prevent bad data. Our platform automatically detects issues in master and transactional data, generates improvement suggestions using AI and human expertise, and prevents problems at the source — across systems like Snowflake, Databricks, SAP, and more.
*The problem we're solving*: Bad data costs businesses millions. Rules get written manually, issues get caught too late, and fixes are slow. We're replacing that with agentic AI that generates data quality rules, finds anomalies, and drives corrections (!) yes, it automatically fixes the broken data — with humans in the loop where it matters. Our customers across industrial goods, energy, automotive, and healthcare are already seeing real results.
*About us*: DQC is a Munich-based AI startup founded in 2022. We're a small (15 ppl), fast-moving team where engineers have real ownership and direct impact on product direction and technical architecture. Short decision paths, no bureaucracy, steep learning curves.
*The role*: As a Senior Backend Engineer, you'll own the full lifecycle of feature development — from architecture and design to production deployment. You'll work cross-functionally with backend, frontend, and product to ship features that thousands of users rely on. Our platform sits at the intersection of backend systems, modern data stacks, and LLM-driven workflows, so you'll be building at the frontier of what's possible with AI in production. We practice agentic coding daily and our tech interview includes a live agentic-coding exercise — we want engineers who embrace these tools with judgment, not hype.
If you want real ownership, direct product impact, and the chance to build at the intersection of backend engineering and AI — let's talk.
Tech stack: Angular moving to React | Node / Bun | ECS | Mongo | Snowflake
Small team doing big things.
We've taken the team AI native, the platform will be there withing a few months. An existing v1 platform built with "boring" technologies allows us to make sure money and data remain safe whilst ensuring the frontend can be built at the speed that AI enables.
One of our team is taking everything they've been playing with for the last couple of years and stepping in to a YC principal role with our blessing. We're looking for their replacement to help continue bringing the team to the same level.
We've spent years creating the brand advocacy category, and are now seeing huge growth in all areas. We took Series A last year, are seeing massive growth, and still finding the time to have fun.
You need to back yourself. We'll expect a lot form you, but you'll be given the autonomy you need to do your best work. We focus on hiring bloody brilliant, utterly lovely people.
No recruiters. The role is being opened as we speak (I'm on holiday, spotted the who is hiring!); for now, please reach out to: joe via duel.tech.
