Best Startups to Work For as a Data Scientist in 2023

Marta Teneva 29 May 2023 7 min read

Have you ever mixed Nutella and soy sauce?

Apparently, running to the local grocery store, stacking up the office with those ingredients, and tasting various combos between the two, is just an ordinary workday for the data science team at Spoonshot – one of the best startups hiring data scientists at the moment. The experiment used Taste Intelligence System (and a lot of trial and error) to find products that share similar compounds with Nutella’s legendary hazelnut and cocoa aroma. In the end, Spoonshot’s taste insights revealed new cross-promotion strategies to increase penetration in under indexing markets for their client.

Sounds like fun, right?

And that’s just one example of the many exciting projects you can work on in the hottest startups.

Why Work for a Startup?

Sure, big data science consultancies have the stability and the benefits every aspiring data scientist strives for. However, you may find yourself working on predictable and often repetitive tasks with little opportunities for growth. At least for the first few years.

Startups, on the other hand, allow you to develop your skillset by trying new things and handling a variety of challenges. Responsibilities there change quite frequently. So, within less than a year you could be doing something entirely different... And a lot more interesting for you than what you were initially hired for. In other words, the sky is the limit!

That said, before you start sending out your resume to Bain and McKinsey, consider the list of best startups for data science we’ve carefully curated for you.
