I’m a senior AI & machine learning consultant, and I help companies make the best use of today's AI technology in order to hit their KPIs. I analyze your data, build machine learning models, and show you how to be more data-driven, using resources you already have in order to reach your business goals. Whether your current pain point is conversion rate, fraud prevention, anomaly detection or any other - your data already knows what you need to solve it, and I can help you find out how.



I’ve been solving problems with data for 13 years, both in academia and in the tech industry. Prior to consulting, I worked for companies such as Armis and PayPal, utilizing big data and machine learning for fraud prevention, risk mitigation, and everything cybersecurity.


Today I work with both startups and more established companies, helping them use their data - and today’s AI & machine learning technology - to drive success.


I also lead the Israeli community of Women in Data Science, utilize ML for whale preservation with the Deep Voice foundation, and offer my expertise with AI and data under the Good Food Institute mentoring program. I have founded the non-profit initiative GreenProtein AI, dedicated to utilizing ML technology for the future of plant-based foods.



I provide many services, some of which are:

1. Working with early-stage startups to refine their vision for incorporating AI into their product, and design both a short and long-term work plan.

2. Helping established companies understand the best ways to use their data in order to eliminate pain points and improve efficiency.

3. Building AI / ML systems to fit a specific need or requirement.

4. Coaching junior data scientists and DS team managers, focusing on both the technical aspects of data science work, and the organizational challenges of implementing it into existing environments.



Noa's presence in the team in the past 2 years has been amazingly significant. Her ability to be at the deepest technical levels and at the same time to clearly communicate project status/details to management & business leaders is scarce and priceless. She is a true partner for strategy discussions and roadmap planning.

Noa's seniority and mentoring capabilities are inspiring and make a difference in the team every single day.

Shoshi Gutreich, Clarivate

Noa quickly assessed our current data landscape and provided targeted advice on extracting value from our data, especially crucial for accelerating our R&D. Noa’s combination of fast-paced insights and deep industry knowledge makes her an invaluable asset.

Shelly Lotan, Medium Well

Noa is insightful, keen and possesses vast experience when it comes to working with data and more specifically machine learning, having a very clear understanding of the process from A to Z. Noa delivered the project earlier than initially estimated as she was able to identify shortcuts worth taking to deliver a prototype-grade solution while making no compromises affecting the core of the project.

Yuval Cohen, Ideal Skill

Throughout the work on the project, Noa showcased remarkable teamwork, extensive knowledge of various machine learning methodologies, and impressive problem-solving skills. Her proficiency implementing ML models streamlined our project, helped us achieve the otherwise tight deadline.

Neta Snir, LeO

Having Noa coaching our team has been a game-changing experience... Her profound knowledge in data and machine learning was evident as she adeptly guided our team through complex technical challenges.

Noa didn’t just provide solutions; she equipped our team with the skills to devise solutions independently. Her guidance has undeniably elevated the proficiency and confidence of our team members.

Inbar Weiss, Snappy

Noa has the rare combination of understanding the big picture while not skipping the details. During her consultation period in PayPal she had a major impact on the high-focus project she was recruited for, allowing to deliver on time.

In addition to her analytical capabilities, Noa has great communication skills, allowing her to succeed in complex projects which involve multiple stakeholders.

Itzik Levi, PayPal

Noa played a crucial role in collaborating with Datacy to pinpoint, refine, and implement a model for topic modeling. I was genuinely impressed by her unwavering commitment to achieving results and delivering value. Her adeptness in engaging with individuals from various backgrounds within the organization, along with her seamless collaboration with the engineering team to achieve the desired results, left a lasting positive impression.

Abraham Elmahrek, Datacy

In her capacity as a mentor for the Good Food Institute, Noa has been a terrific addition to the program... Noa is driven, dedicated, and smart. The startups she helps come away from their engagements with her feeling inspired and far better informed. Working with her has been an absolute pleasure and we are thrilled that she is willing to share her vast knowledge for the betterment of our sector.

DevFest 2020 - Noa Weiss - The Unspoken Problems With Machine Learning in Security

Machine Learning is the hottest buzzword. Everybody loves it, everybody sells it. But why is it that while fields such as Computer Vision or Natural Language Processing have stellar achievements, with new record-breaking models published every other week, the Cybersecurity industry staggers behind? Are Anomaly Detection algorithms – so well beloved for the prevention of attacks and of fraud - really suitable for those intended purposes? What price do we pay for keeping things hushed? Where do our huge datasets fail us? And how, once we spot these issues, might we try and solve them? In this talk I will go over several points that hold us back, among them: our rapidly changing input data, and who’s to blame for it; the known issues of imbalanced & untagged datasets, and why our solutions for them are insufficient; and, finally, the biggest culprit: the confidential nature of our field, and how it keeps us from being great. The unspoken problems with Machine Learning in security: let’s talk about them. Language - English Noa Weiss Noa is an AI & machine learning consultant who’s been playing with data for over a decade, both in academia and in the tech industry. Prior to freelancing, Noa explored the world of risk & security, working for companies such as Armis and PayPal, as well as consulting startups on fraud prevention. In her spare time she leads the Israeli community of Women in Data Science, utilizes deep learning techniques to improve whale research at the Deep Voice foundation, and mentors junior data scientists taking their first steps in the field.
