Show HN: Sumble – knowledge graph for GTM data – query tech stack, key projects

I’m Anthony, co-founder/CEO of Sumble. I was previously co-founder/CEO of Kaggle. Sumble is my newco with Ben Hamner (former co-founder and CTO of Kaggle).

### What we built

Sumble is a knowledge graph for go-to-market teams. We allow you to run very rich queries to identify prospects at a granular level and be able to do very targeted outreach.

Sumble allows you to find:

- tech stacks (in larger companies, down to the team or buying group level) - key projects those teams are working on (cloud migrations, GenAI initiatives, etc.) - people involved in those key projects

For example, here's a list of GenAI projects at Capital One that involve RAG/Vector databases: https://sumble.com/l/6sDqKmhyAH

And this view includes a list of people who we think are involved in a particular project being undertaken by the AI Foundation Team at Capital One: https://sumble.com/l/j8mbRrDsly

These views allow you to reach out to that team with a granular understanding of what they are working on.

### Inspiration

Sumble was very much inspired by our experience at Kaggle:

1. Kaggle’s public-data platform showed us how hungry people are for high-quality data (the metrics on that product were really strong)

2. At Google we saw knowledge graphs unlock powerful and composable queries

### Trying it out

- The app is live today; you’ll need to log in (Google OAuth or magic links)

- Most functionality and data are free; we only charge individual users for bulk exports

### How it works (briefly)

- Sources: job posts, resume data, company websites (more to come!)

- Extraction & linking: We use LLM (mostly fine-tuned models) to extract entities out of text from sources (company → team → people on a team → projects the team is undertaking → technology the team uses)

### What’s next

- Adding more sources so you can run even more composable queries

- Opening an API so devs can hit the graph directly

- Much later: expand to use cases beyond GTM

### Feedback

- Is the web app intuitive?

- What queries do you want us to prioritize supporting in an API?

- What additional external data sources would you like us to prioritize? - What workflow improvements/integrations would you find most helpful?

As in a search box where you can ask free form queries rather than applying filters? We haven't heard much demand for that yet, so haven't prioritized it. We will if it's a common request.

Sumble has been my critical tool to research the organization structure and responsibility in a large company, technology adoption like which organization has the LLM adoption.

Congrats on the launch!

As the founder of another product in this space - this is super impressive and well built. Great demo video and congrats on top of HN! Getting this smooth UX and data behind the scenes is not easy.

Nicely done. Do you have a roadmap, public ticketing system or communication channel?
