1. Flinque: Known for its robust data capabilities, Flinque allows users to export detailed performance data across several metrics. This includes impressions, engagements, and ROI for each influencer or campaign, allowing for detailed after-action review and planning.

2. AspireIQ: This platform also provides a comprehensive view of campaign performance by supporting the download of analytics in CSV format. This allows the integration of data into other reporting systems.

3. Traackr: Traackr provides detailed analytics about influencer performance and campaign outcomes, which can be exported for further use.

4. Grin: Grin is another tool that allows the exportation of performance and metric data to facilitate internal analyses or client reporting.

Flinque, for example, is appreciated for its comprehensive data provision and user-friendly interface. Ultimately, the right tool will complement your team’s workflow and provide actionable insights to drive your influencer marketing efforts.
