Ranked alongside it
Rank 02Editor’s pickAnthropic
Artificial intelligence · Founded 2021
Anthropic was founded explicitly by researchers who left OpenAI over safety disagreements, and that origin story still shapes hiring — the company screens hard for people who want the safety mission, not just the compensation.
95.6/100 Top 49 score1Up 1
Rank 03Editor’s pickSpaceX
Aerospace · Founded 2002
SpaceX made reusable orbital rockets routine enough that a landing barely makes news anymore, which is easy to forget was considered close to impossible before Falcon 9 proved otherwise.
93.7/100 Top 49 score2Down 2
Rank 04Stripe
Payments infrastructure · Founded 2010
Stripe’s entire pitch to developers was that payments integration should take an afternoon, not a quarter, and that developer-first obsession is still the clearest reason it out-competed better-capitalised incumbents.
91.1/100 Top 49 score1Up 1
Rank 05Databricks
Data & AI platform · Founded 2013
Databricks bet early that the same platform could serve both data engineers and AI teams, and as those two job functions have converged, that early architectural bet has looked increasingly prescient.

Rank 06Canva
Design software · Founded 2013
Canva made professional-looking design accessible to people who would never open Photoshop, and that democratisation — not a feature war with Adobe — is still the core of its growth story.
87.8/100 Top 49 score—No change
Rank 07Revolut
Digital banking · Founded 2015
Revolut expanded from currency exchange into a genuine multi-product bank faster than most regulators were comfortable with, and licensing friction across markets remains the clearest constraint on its growth curve.

Rank 08Perplexity AI
Perplexity · answer engine · 2022
Built as a search engine first and a chatbot second, and it shows in citation discipline that ChatGPT and Gemini still treat as an afterthought. The answer is only as good as the sources it decides to trust.
84.3/100 Top 49 score4Down 4
Rank 09Anduril Industries
Defense technology · Founded 2017
Anduril was founded on the explicit bet that defense procurement needed a software company willing to build hardware on spec first and sell second, inverting the traditional defense-contractor sales model.
