17th August, 2023

Machine learning has come a long way. After decades of research, machine learning went mainstream in 2012 when an AI solution won the ImageNet challenge by a whopping margin of 10.8%, or 41% better than the runner-up score!

From very limited usage in the business world before 2012, machine learning dependency has gone up exponentially since the boom. Today there are 9k+ machine learning startups and companies according to Crunchbase.

It’s been said that in the world of AI and ML, the speed of technological advancement is extreme compared to the pre-AI era. Our new remote work culture only added more fuel to the acceleration of machine learning research. New ML models do things that were unthought-of even a year ago, which has given birth to some exciting startups to watch out for in 2021.

But first, we need to decide how we’re going to rank different machine learning startups and companies:

  • Results and performance – this is a no-brainer. Game-changing results and great performance are every CIO’s dream. A big part of generating good results is the quality of data fed into the ML solution. If an ML solution offers to mine excess data to integrate with your available data, that’s a cherry on top of the ML cake. More data leads to better possibilities of accurate trend recognition. Performance depends on optimization and the processing power of the solution provider’s server.
  • Easy integration with your framework – every tech company has a tech framework. For startup companies, these frameworks should be flexible and accommodative. For older companies, traditional (and usually monolith) systems form most of the framework. So, depending on the requirements and after assessing the current framework, we can decide if integration is easy. Top-ranking ML solutions will be the ones that cover the most ground.
  • Ease of management – less is more. Take the aesthetic design of Apple products for example. Despite being the least cluttered and most simple, these products deliver maximum satisfaction to the user. Similarly, ML solutions that deliver value with the least clutter are often the best pick. Dashboards, clean UI, and smart linkage can make all the difference. Also, if it’s a tool for team usage, facilities such as task assignment and management overview can be great add-ons.
  • Easy integration with relevant third-party tools – Machine learning keeps evolving. Every other day there’s some amazing breakthrough that data scientists jump at quickly. Similarly, new tech and tools enter the standard ML toolset every few months. A good ML solution should have the flexibility to evolve its integration capabilities over time, and should have a standard set of integrations available at all times.

Now that we have this covered, let’s move on to our list!

Ranking the top 15 Machine Learning startups to watch in 2021

ML startups to watch

There are plenty of startups that provide interesting ML solutions and fit our criteria, so I tried to focus on those that are the most interesting, but perhaps not as popular as FAANG-related ML projects.

1. DataVisor

ML startup Datavisor

Cybersecurity can only improve when AI comes into play, and DataVisor has proved it fair and square. DataVisor is an AI/ML solution for increasing the accuracy of fraud detection on a platform level. It has a dynamic (evolving) database of over 4.2 billion user accounts from all over the world. With the help of this data and proprietary unsupervised machine learning models, DataVisor delivers real-time learning with high-value results. It detects fraud before it’s done, by tapping into subtle data patterns that a human, or a traditional system, wouldn’t notice. DataVisor customers are mostly financial services, e-commerce platforms, marketplaces, and social platforms – companies that need protection against financial mishaps and reputational damage. 

2. Delta AI

ML startup Delta AI

The internet has become a content hub where people (potential customers) willingly share their stories, quirks, and preferences in formats such as text, photos, and videos. The toughest nut to crack in this case is video. According to Delta AI, 85% of a given video is obscured from the usual text-based search. This is where Delta AI comes in with advanced computer vision technology, to leverage similar content to understand how a product appears in a natural context. This new approach towards understanding potential customers purely through the products they use has the promise of being way more efficient than traditional customer segmentation techniques.

3. Particle
