Personal Roadtrip Hackathon

A hackathon is generally an event a small group collaborates together to build a product or prototype in a very short period. Some of the more popular sponsored examples (such as the ones during the TechCrunch Disrupt series) usually last for 24 hours.  For a while, I have been intrigued by the concept and have wanted to see what I can accomplish. Unfortunately I have not had the opportunity to enter one with my always busy schedule and family commitments.  This weekend I had a ... [More]


The Moneyball Effect

9. October 2012 23:26 by Jay Grossman in   //  Tags: , , ,   //   Comments (0)
In 2004, Michael Lewis wrote this book called "Moneyball: The Art of Winning an Unfair Game" detailing the focus of the Oakland A's (baseball team) on analytical, evidence-based, sabermetric approach to assembling a competitive baseball team, despite a disadvantaged revenue situation. The central premise of Moneyball is that the collected wisdom of baseball insiders (including players, managers, coaches, scouts, and the front office) over the past century is subjective and often flawed. Statist... [More]

One of the reasons I love working in Manhattan is all the cool opportunities to learn and the networks of interesting people. Every Monday I receive an email from tech investor Charlie O’Donnell  with classes a list of classes and meetups for entrepreneurs going on around New York City. Last week I found out and signed up for a high level class on Bayesian Theory and probability (called Bayesian Theory and the Theory of Life) that met during lunch time a few block... [More]


Is the Right Selling Price an Optimized Price?

I think every person running a business needs to regularly ask themself the following question: Given our operating constraints, what is the best mix of products and/or services for us to produce and sell in the period, and at what prices, to generate the highest expected revenue? Whether you are selling penny candy or you are a retainer lawyer with a huge hourly fee, the basic concepts are the same.

As I have mentioned in previous posts, understanding pricing and market values has been a passion of mine for over 20 years. With many problems I encounter (especially those related to business or technology), I try to follow these steps borrowed from agile software development methodology: DEFINE - Define the problem/goals, identifying clear and measurable requirements.  ANALYZE - Analyze the each requirement to identify or design potential solutions.  IMPLEMENT - Establish/Impl...

Is Searching eBay a reliable way to determine Market Value?

22. August 2012 22:23 by Jay Grossman in   //  Tags: , , , , ,   //   Comments (0)
Disclaimer: I am a huge fan of eBay and the significant disruption they brought about for buyers and sellers. I have been a frequent buyer and occasional seller on the site since 1998 and continue to use it every day. Nothing in this post is meant to put eBay (the company or marketplace) in a negative light. I have seen a good many people base their selling and purchasing decisions solely on data they can find from the closed listings from the past 60 days for a particular search on eBay. ... [More]
