Let’s start out by saying that I’m a big fan of both Uber and Lyft. I’m indirectly an investor in both companies as I’m an investor in three VC funds that are investors in Uber and one VC fund that is an investor in Lyft. I have no idea how much actual equity I have in either company, but based on current valuations the dollar value of my indirect ownership is non-trivial. And Foundry Group came close to investing in Zimride (the predecessor to Lyft) but we ended up withdrawing from what we thought was an inappropriately high-priced round, which, in hindsight, was clearly a miss on our part.

Regardless of my support and enthusiasm for these two companies, I’m bummed at the mud they are slinging at each other. I get that this is an intensely competitive market. I get that the stakes are huge. I get that all the reporting I’m reading is second hand and might be fiction. But the ad hominem attacks are escalating rapidly, and the behavior they are surfacing isn’t pretty.

TechCrunch summarized this pretty well yesterday, after multiple articles from a variety of places including the NY Times and WSJ. The headline sets the tone: Uber Strikes Back, Claiming Lyft Drivers And Employees Canceled Nearly 13,000 Rides. The NYT article is Accusations Fly Between Uber and Lyft and the WSJ article is Uber and Lyft Rivalry Turns Nasty in War of Words.

I have no idea what, if any of what is being said, is true. The tactic being asserted that is most disturbing is this one:

Accused Lyft behavior: “Lyft employees, drivers and one of its founders ordered 12,900 trips on Uber’s app and then canceled them with the goal of slowing down drivers who would otherwise be picking up actual, paying passengers.”

Accused Uber behavior: “177 Uber employees have requested and quickly canceled more than 5,000 rides from Lyft drivers over the past 10 months, Lyft said, in an effort to frustrate Lyft’s customers and drivers.”

As a customer, this sucks. If I was a driver for either service, this sucks. I think this ultimately backfires against each company equally.

People: Both of you are trying to disrupt a massive market dominated by incumbents and government regulation. I’m sure these incumbents are now laughing their asses off at y’all acting like petulant children as they wait patiently for you to chew up capital, value, partners, and customers while generating additional scrutiny from the government forces in the incumbents’ pockets trying to slow you down.

I get that you believe price is a weapon; how you use it is for you and your investors to decide. But by messing with each other’s services, especially in a way that negatively impacts your two key constituents, consumers and drivers, you are opening yourself up to a ridiculous amount of scrutiny and quickly playing a no-win, zero-sum game. There is no need at all for this given the massive size of the market opportunity before you.

One or both of you should rise above the fray. Keep on competing aggressively. But recognize that you are radically disrupting a market desperately in need of disruption and doing it beautifully. Don’t shit all over it and yourself in the process.
