In this blog post, I explore ~70,000 VC transactions between 2010 and 2020, focusing on co-investments. Specifically, I explain which VCs co-invest the most with each other, which pairs of VCs have the largest amount of co-investments, and the fraction of successful investments for a given pair of VC co-investors. To understand the data source and process, feel free to read the first section. Otherwise, skip over to subsequent sections to see the uncovered insights. I would like to thank Hiba Habbat, student at African Leadership Academy, for her valuable help in retrieving and cleaning the data.

Understanding the Data

The data source

In this blog post, I teamed up with to tell the story of this eventful year in 20 graphs. Most of the graphs in this post are borrowed from other sources (all properly cited), and a few are constructed based on available data. While we did not include any graph on the global coronavirus caseload or the death toll, we recognize the immense pain associated with the loss of every human life.

Using 1.7 Million data points in FIFA (the PlayStation game) datasets to “clone” FC Barcelona’s 2014/2015 squad.

In this blog post, I use the widely available FIFA datasets, a simple data science algorithm, and a tribe of football “experts” (really, just my friends and I) to construct the closest team to the FC Barcelona team of 2014/2015 with available players today (in 2020).

As a reminder, the 2014/2015 squad, while not as legendary as the one in 2008/2009, won everything there was to win (6 trophies to be precise, including La Liga and the Champions League). …


Following up on my earlier post on , and digging deeper into venture capital in EdTech, this article explores the space’s trends, players and insights between 2015 and 2020.

This article contains a small part of the insights that I was able to generate with this dataset. To stay up-to-date on my future posts on the topic, or to suggest additional analysis you’d be interested in seeing, . I will email you the articles when they come out.

Important Note: The analysis below depends entirely on the accuracy and completeness of the Crunchbase…


On an otherwise boring Friday night, I decided to launch a poll on my Instagram to ask my friends if they had tested positive for COVID-19. This post recounts the story.

As the days of 2020 went by, I started counting the number of people that I knew who had tested positive for COVID-19. By mid-October, that number reached 16 people. These are either friends, acquaintances, or family members who had told me that they had tested positive for COVID-19. My immediate reaction was the following: if the official statistics are to be trusted, the world incidence rate of COVID-19…


I thank my friend Luca Sartorio for giving me access to ata on the stringency of COVID- related lockdowns, as part of his reseatch at the Torcuato di Tella University in Buenos Aires.

COVID-19 has upended the entire world in 2020. The economic news from Q2 of 2020 are bleak: most countries in the world witnessed a sharp contraction of their GDP growth, resulting from the crisis. In this blog post, I correlate this decline in GDP growth with characteristics of the pandemic (e.g., incidence and death rates in countries), and the macroeconomic conditions in select countries (e.g., foreign…


Descriptive statistics of previous Supreme Court appointments by US Presidents from 1945 to present.

“My most fervent wish is that I will not be replaced until a new President is installed”

Those were the dying wishes of Justice Ruth Bader Ginsburg, who passed away yesterday (September 18, 2020) due to complications from cancer.

The news of the passing of Supreme Justice Ruth Bader Ginsburg reverberated across the US and the world. Millions are mourning and grieving a feminist icon who has tirelessly worked to ensure gender equality through the Law.

Even before her passing could be properly mourned, it has…


COVID-19, for all its disastrous effects on countless lives, has accelerated a positive trend that we’ve all been witnessing over the past few years: the move towards digital education. As schools and universities were shut down worldwide in March 2020, parents, educators and students alike scrambled to find a close substitute to something we think of as irreplaceable: in-person education.

As a response to these unusual circumstances, education-themed companies have proliferated across the world. Investor interest in these companies has increased, even as economic downturns reverberated across the world. To understand and quantify the (increased) value that society has put…


In this blog post, I take a step back and reflect on my 3-month data science & Medium journey.

Facing a bright, blank screen, I wondered if I should even start typing.

My thoughts serenaded me with a hundred questions: What am I getting myself into? Do I have the time, stamina and creativity to do this? Will I consistently find interesting things to write about? Will people even read my stuff?

What saved me from all that self-doubt was a familiar voice. The voice that urges us to take that new job, to jump from an airplane (skydive!), to…


Using text mining and natural language processing (NLP) to derive insights from last week’s Big Tech Congress Hearing (July 2020), featuring the CEOs of Amazon, Apple, Facebook, and Google.

On July 29, 2020, the CEOs of the four of the largest and most powerful US technology companies (virtually) convened to address the At this marathon-hearing, which lasted more than 5 hours, Republicans and Democrats came together to grill the CEOs on their perceived anti-competitive practices and other market powers that they are accused of abusing.
