I would say that it is 100% a good idea with a couple of caveats.

First, your syndication destination should already have an audience who aligns closely with your startup's desire clients / customers.

Second, the syndicator must allow linkbacks to your website.

So definitely go do it - if it builds audience with prospects and also if it can be made to drive traffic back to your website.

The key to appraising whether these things are appropriate, are all about building audience, testing the market and getting early adopters.

So consider your articles and whether a call-to-action can be added to the bottom of each one that drives the interested reader to your website. When they get there, can you capture their details by offering something to the reader?
