Te US timber prices down 50% in a month. This is what happens when everyone starts renovation at the same time. Volatility will be significant. Timber prices are a great clue how commodities can and will behave in such a scenario. Btw, timber prices are still up substantially.

1/ new essay: What's next for marketplace startups? Reinventing the $10 trillion service economy, that's what. Co-authored with @ljin18 https://t.co/fgKbrHTnH5. A short thread 👇

2/ Marketplace startups have done incredibly well over the first few decades of the internet, reinventing the way we shop for goods, but have been less successful services. It's bc services are complex, subjective, fragmented, and often in real life. Makes it hard

3/ There's been 4 major eras at making the service economy work online. The Listings Era, the unbundled Craiglist era, the Uber for X era, and the Managed Marketplace era

4/ Each era has added more value than the last, and utilized technology innovations, from internet to social / "read/write web" to mobile. The "Unbundling Craigslist" era was particularly epic at generating startup ideas

5/ The problem is, all the low-hanging fruit has been picked off. The techniques that got us to here won't get us to the next phase. So we have to do some pretty different things. That's why "Managed Marketplaces" have been a big deal - hire folks as W-2s, certify quality, etc.

1/ I am seeing more and more founder secondary in venture rounds (Secondary = founders selling some of their shares before some other shareholders are able). Series B-D. I see both as an investor and through entrepreneur circles.

2/ I like secondary for entrepreneurs. Moderation is key but in a lot of situations I think it helps accelerate the co. Lots of very smart investors disagree. Here are my thoughts.

3/ Magnitude: My basic rule of thumb from what I see is market is 4+ yrs and up to 10% of founder’s equity stake with some $ cap that makes sense given stage etc. (typically <$10m)

4/ The entrepreneurial journey is brutally hard. Giving some financial relief helps remove one piece of pressure. I don’t think that secondary in the magnitude mentioned impacts the drive/persistence of great entrepreneurs.

5/ That secondary means they will be able to just sleep knowing they can pay their kids’ tuition. Secondary will make most founders better at their jobs, thus accelerating the co.

1. Now that Stan Lee is being eulogized far and wide, it's important to remember how marginal Stan Lee and his collaborators (Jack Kirby and Steve Ditko) were in the 1950s and 1960s.

2. Marvel Comics (before that Atlas) was just a cog in the machine of a bottom pulp publisher run by Martin Goodman, the husband of one of Lee's cousins. It was the lowest of the low in the publishing world.

3. Now Mario Puzo (not yet the author of the Godfather) shared offices with Stan Lee in the 1950s and 1960s. Puzo wrote for garrish men's adventure magazines and, like Lee, dreamed of writing a novel & breaking out. But Puzo looked down on Lee.

4. Flo Steinberg, 1960s secretary at Marvel: "They were always making jokes about us. They'd come in and giggle. mario Puzo would look in and would see us all working on his way to the office and say, 'Work faster, little elves. Christmas is coming.'"

5. When JFK was killed, the whole office of Magazine Management was stunned and quiet. Except Lee. He continued working. "He was still working on the comic books," Puzo said. "Like that was the most important thing in the world."
