Thoughts on Alteryx

One month ago, I posted comments to SeekingAlpha.com (http://bit.ly/2hX9HyA) on the positive short & long term prospects of Alteryx stock.  At the time, the stock price was at $21.98 and in just 30 days, it has since increased in value by 24% so I thought I would re-share that feedback here:

I have been the 1st internal adopter of Alteryx at 2 Fortune 50s & a Big 4 IT consultancy and I can assure you, the cat will soon be out of the bag (re: Alteryx stock movement). This article does a fantastic job of outlining how Gartner & investors haven't historically appreciated Alteryx. However, business analysts & young data scientists in all functional areas (finance, hr, mktg, sales, acctng, ops...) & all industries do appreciate them and understand this offering. That is why they score so high in net retention + just won the 2017 Gartner Peer Insights Customer Choice Awards for Business Intelligence and Analytics (announced last week).

The market is used to seeing a product competing in one of the following categories: information management tool (ETL), cleansing & enrichment tool, BI tool, a reporting tool, an advanced analytical, a geospatial tool & an application to manage it all. Some companies compete in 2 (maybe 3) but Alteryx does it all. Furthermore, they do it with a slick GUI interface that eliminates the need to code (sql & open source R that can be edited if desired). 
This is a game changer for organizations paying large salaries and competing for data professionals with coding skills. It means you don't need as many quants. Alteryx even addresses 2 major problem most others ignore--managing long, error-riddled code and creating a social environment that allows analysts to share, explore (data lineage & quality) & rate data (think Amazon review).

If people think that Alteryx is expensive, they just don't understand how much it would cost to acquire the same capabilities, how many vendors it would require to deal with and and how complicated it is stitch them all together.

I know at least 2 of the Big 4 accounting firms are heavily invested in Alteryx on 2 fronts--using to drive internal efficiency across their org and to drive efficient deployments as a service externally. I believe those organizations intend to rake in billions in consultancy revenue using and deploying this capability into enterprises over the coming years.

Disclaimer: I built a consultancy on this capability & I am an investor. I am also a current customer where I manage a rapid analytics team at a multi-billion dollar healthcare company.

NYC Restaurants Are “Improving” Just Don't Read About The Violations

By: Robert Ayala

Interactive Data Visualizations Below

The City of New York provides detailed information regarding their grading/scoring of NYC’s restaurants.  The City has been building out this database since 2009 and is currently tracking more than 25,000 of the City’s restaurants.  Each restaurant’s score, violations, grades, and inspection dates are tracked, which allow for detailed analyses and data visualization opportunities.  Here is a chart that details how restaurants are graded, keep in mind that you want a low score:

Scoring:
7 points for a Public Health Violation;
5 points for a Critical Violation;
2 points for a General Violation; and
Additional Points Based On Severity of Violation

Grading:
A = 0 - 13 points
B = 14 - 27 points
C = 28+ points
P = Score Pending
Z = Closed

This grading scale is interesting because a restaurant can have both a Public Health and Critical Violation yet still maintain an “A” rating.  As you will see below, some of the violations are unsettling.

NYC restaurants as a whole have decreased their score from 16 to 13.9, which shows improvement.  It would be great to have data regarding which inspector graded each restaurant to see which inspectors are more thorough and which tend to be lenient, but that information is not being collected.  I have created three interactive visualizations from this data set which appear below by applying data transformation, analytics, and visualization methods.   

NYC Restaurant Review: 

Pick your favorite restaurant and see what violations they have!

This interactive visualization allows you to pick any restaurant in NYC, see their score/grade over time, latest grade, latest violations, and the average score of restaurants in the same zip code.

I have noticed that many restaurants who receive a poor grade improve drastically for their next grading but tend to deteriorate back down to a poor grade eventually, and repeat this process.

If a restaurant has multiple locations, click on the location in the legend to see a highlighted view.

 

NYC Restaurant Overview:

This dashboard displays each zip code in NYC and the average score of restaurants in the zip code.  It also depicts the average score of all restaurants in NYC over time, as well as the grossest violations that occur and the number of times those violations have occurred.

You can zoom in on the map, select a certain area, or hover over different zip codes to get more information.

NYC Restaurant Cuisine:

This depicts the restaurants in NYC by cuisine; showing the number of restaurants, the average score of those restaurants, and the percentage of total restaurants in NYC. 

Select the cuisine from the legend to highlight, and then place the cursor over it to access additional information.
