Awesome! Could you share a bit about business model?

hi, co-founder of QuestDB here.

QuestDB is open source and therefore free for everybody to use. Another product using QuestDB as a library with features that are typically required for massive enterprise deployment will be distributed and sold to companies through a fully managed solution.

Our idea is to empower developers to solve their problems with QuestDB open source, and for those developers to then push the product within the organisation bottom up.

I'm not associated with QuestDB, but if it's anything like the other open-source startups I work with then the business model is probably selling a managed or hosted version of the DB with enterprise benefits like security compliance, SLAs, and engineering support. In that case the open-source DB will act as a driver of awareness and of demand for the commercial option.

Hi Vlad - your anecdote about ship tracking is interesting (my other startup is an AIS based dry freight trader). You must know the Vortexa guys given your BP background. How does QuestDB differ from other timeseries/OLAP offerings? I'm not entirely clear.

thank you, life is an interesting experience :) I used to work with Fabio, Vortexa CEO and had to turn down an offer of being first employee there to focus on QuestDB. They are an absolute awesome bunch of guys and deserve every bit of their success!

What makes QuestDB different from other tools is the performance we aim to offer. We are completely open on how we achieve this performance and we serve community first and foremost.

Hi Vlad, this looks really interesting! I really enjoyed reading the backstory and the founding dynamics upon QuestDB was born and I think a lot of others in the YC community will as well. Can you give some use cases or specific examples of why QuestDB is unique?

thanks! What differentiates us from other time series databases is the performance. Both for ingestion and queries. For example we can ingest application performance metrics via Influx Line Protocol and query them via SQL and both should faster than incumbents

Am I the only one that's like "wtf is a time-series database compared to a normal one?"

In general, imagine a problem space where you have millions (or much much more) of timeseries, each is potentially millions long (usually it's purely floats), and you want to perform time-series specific operations, like interpolate, extrapolate, moving avg, forecast, alert if ususual, plot, etc. Like, imagine AWS has 100s-1000s (or more) of metrics per "thing", and there's a very large number of things (EC2 instances, subnets, SageMaker instances, network switches, etc). Very specific data model, usually append-only, very specific read operations.
