“That same unbundling that happened to Craigslist is now about to happen to LinkedIn.”

First, LinkedIn does not cover every job category sufficiently. For example, blue collar workers have never been able to use LinkedIn to showcase their work history and to find new opportunities.

the fractionalized labor marketplaces tend to have high repeat usage on the supply side because the workers come back frequently to find the next money-earning opportunity.

The more verticalized, the better.
Identify a vertical with frequent repeat usage.
Defend against disintermediation.
Consider possible data moats.

Once a startup achieves a dominant position in the hyper-vertical market, it can often extend its business into adjacent markets.

The stronger the value proposition to each of the participants, the stronger the tailwind for rapid growth of the marketplace.

high repeat usage on the supply side often happens when the marketplace is focused on short-duration assignments (gigs or shifts vs. full-time jobs).

Disintermediation can be particularly acute when there is high loyalty or a high degree of trust between the demand side and the supply side.

focus on a vertical with homogeneous supply
provide value-add tools or services for one or both sides

Uber is a great example of this since riders are willing to ride with a different driver each time; the rider’s trust lies with the marketplace, not with a specific driver.

Many vertical labor marketplaces have a data moat that creates defensibility for the marketplace. This data moat often comes in the form of reviews or feedback about the workers on the supply-side of the marketplace.

As a worker receives more feedback from more demand-side participants, the worker is able to get future jobs more easily, which creates stickiness for the worker.
