Profile bio

About David Weinstein

David Weinstein is a Co-Founder at KayOS. He possess expertise in sql, sas, financial analysis, financial modeling, economics and 32 more skills. He is proficient in Hebrew. Colleagues describe him as "David is one of the most talented, versatile, and humble analytics leaders I’ve worked with. Over the past three years, I saw David grow through various roles, teams, and challenges. His consistently positive & collaborative attitude, combined with a unique ability to wear both strategic / high-level and executional / technical hats, has led him to be an instrumental thought partner in any and all growth challenges. There are very few, if any problems that I would not turn to David to help solve — he is someone I will actively seek to work with again and again, in any context." and "David (DW, DDubs) is stellar. He's whip smart, cool under pressure, and the one of the nicest guys you'll ever have the honor of working with. Pretty much everyone at Tilt depended on David. He worked with me on marketing analytics, our international Community teams on community analytics, our Finance team on financial & business strategy / planning, our Product team on product analytics, our senior leaders on high-level company analytics (as well as fundraising)...and he did it all without missing a beat. Sometimes I don't know how he juggled it all, but he did it with aplomb and good humor. David built and owned Tilt's first-ever Operational Model, which defined our key metrics, charted growth across them, and projected growth into the future. This was a hugely impactful and sensitive project, throughout which we all appreciated his expertise and transparency. David's Operational Model ended up being the source of truth for growth planning and resource allocation -- an enormous help to me in finding focus and building out our operational muscle accordingly. David and I also worked together on a small team to build an internal A/B testing framework and tool, which raised the bar on experimentation at Tilt. David's logical thinking, wizard-like SQL chops, and steady confidence brought us to solutions that dramatically reduced the barriers to entry on experiments (reduced setup and weekly maintenance time by 10x) and led to awesome growth learnings (e.g. saved money on incentives that didn't drive additional conversion). You want David on your team. He's an all-star."

Listed skills include Sql, Sas, Financial Analysis, Financial Modeling, and 33 others.
