Zenkit, a startup from Karlsruhe, Germany (full disclosure: I know them) markets itself as a more flexible Trello alternative.
And they're right! We recently switched from Trello to track our outreach "funnel". Here are a few things that I especially love about the tool:

Additional labels: I added labels like location, introduction from, outreach channel, contact details, outreach "angle" and others. I can store (and group by) all information I want. This makes it a really powerful CMS
