Reflections on Palantir

Can someone explain to me what is the Palantir's business model ? I haven't heard any large, meaningful project they been involved in, but I keep hearing the company name & how hot they are and their stocks are going to blow-up any day (some of my friends kept their stocks for the last 4-5 years with very little gain compared to other software companies). I know of the smaller software companies that are less than 100 people and have a very meaningful impact in DoD & Gov space.

When I interned at Palantir (summer 2014) their business was mostly in data ingestion, visualization, and correlation.

A typical workflow for a Palantir customer was that Palantir would come in and dump a ton of data out of old crufty databases and into Palantir's datastore. Then, they'd establish connections between that data. This is all sounds kind of hand-wavy, but the gist of it is that a lot of government agencies have data that lives in separate databases and they can't easily correlate data between those two databases. Once the data was in Palantir's system, they could do queries against all their data, and make connections and correlations that they wouldn't otherwise be able to find when the data was previously siloed.

One of the sample use cases was identifying people filling prescriptions for schedule II drugs multiple times on the same day, and correlating that with pharmacies run by people connected to known drug traffickers. Previously, this was hard to do because the database of prescription purchases was disconnected from the database of drug convictions.

People dismiss this type of work as no big deal, but in my experience this is the actual hard work of producing something useful for companies, and what 90% of SaaS resellers will never be able to deliver on.

Yes, it is very hard. But does Palantir succeed? Or do they like some other companies just trick customers with big wallets to buy?
