Our team began creating web publishing tools in 1998, when we launched a SaaS CMS for newspapers in France.
Then, in 2002, we launched a DIY ad network for blogs, the first social media advertising platform.
In 2010, we created a tool to help people on Twitter, who we thought of as micro-publishers, better understand their own networks.
Last year, we created Quizlab to help Substack creators better engage readers, boost loyalty and reduce churn.
Now we’ve created Skyangles, which offers Bluesky users many of the insights we developed for Twitter 15 years ago.
If you’re on Bluesky, you can use Skyangles to quickly distill a list of your biggest followers, both those you’ve followed and those you have not (yet) followed back. Just load in a Bsky handle and Skyangles does the rest.

Too busy to examine each and every new follower, many accounts have no clue how influential some of their followers are. For example, does former Twitter honcho Jason Shellen, with ~1,500 followers, realize he’s followed by Atlantic photo editor Alan Taylor, who has 22k followers? This fact is unearthed by Skyangle’s list of Shellen’s “fans,” ie followers that an accounts hasn’t followed back.
Skyangles also can be used to identify who two accounts both follow, which is a great way to locate hidden influencers for a given domain, locale or workplace. Load in two handles and click “analyze.” For example, here’s a list of 31 Atlantic Magazine staff, accounts followed in common by writers Tom Nichols and Elaine Godfrey.
One final fun feature in both search modes: a word cloud based on the bios of discovered accounts. Below is the cloud for the accounts followed by both Nichols and Godfrey.
