I never write review but I just have to for this. This is the COOLEST software ever. I'm learning so much about who orders our products and it's perfect as we recruit affiliates to share about our product. I know exactly the persona and can better target them.
OuterSignal has been an incredibly valuable tool for our team and has served as the foundation for building many of our internal personas. The depth of insight it provides has consistently impressed me, and the team behind the product has been equally strong to work with. It has also helped us identify high-value customers and VIPs purchasing our product, which has directly led to meaningful partnership opportunities. Highly recommend. The leverage this tool creates is significant—it delivers the kind of output that would otherwise require a much larger team.
A time hack for small nimble Shopify DTC brands without an insights department. What would've taken months to build out our segments based on occupation and purchase behaviors took 24 hours. It's a really effective way to gain a quick and high-level depth of your customer base while also being instantly useful for paid media targeting and comms. Also loved how its integrated with Klaviyo and slack.
Outersignal gives us extraordinary insight into our customer base. We are now able to build and automate bespoke outreach to connect more meaningfully with our customers, and the persona tools have unlocked valuable new opportunities in our ad strategy. Every Shopify store should have this in their stack.
So far Outer Signal has been incredible to see so much of our customer data. We were really just guessing before and this has unlocked so much opportunity for marketing, affiliate, etc.
We're amazed with the world of possibilities Outersignal brings to our business. Similar to others, we've spent a lot of time trying to build out personas. Outersignal helped us deeply (and very quickly) understand our customer and makes it easy to refine our acquisition and retention strategies.
Outersignal has been a solid addition to our Shopify stack. Simple, effective, and the team is super responsive. Really happy with it.
Very powerful but accessible tool. Lots of interesting and actionable insights. Looking forward to deploying across the funnel as we scale our consumer channels.
