TangoEye vs Double

TangoEye is in-store retail analytics and automation software that turns existing CCTV cameras into footfall, zone, and conversion data. Instead of manual clickers or new sensor hardware, it plugs into the camera network retailers already run. The platform splits into four modules: Tango Traffic for walk-in counts, Tango Zone for shelf and area heatmaps, Tango RevOp for missed-sale tracking, and Tango StoreOps for camera and network uptime.

Most retail analytics vendors sell dedicated counting sensors or gate hardware. TangoEye's pitch is pure software on top of cameras that are already mounted, which keeps rollout cost lower and avoids ripping out existing infra. That trade-off means you need working CCTV coverage and bandwidth at each store, but you skip the cap-ex cycle of installing parallel sensor networks.

Retail operations teams use it to see bounced visitors, engaged shoppers versus casual walk-ins, and zone-level dwell time without standing at the door with a tally counter. Brand leaders at multi-store chains like Lenskart and Nykaa, listed on TangoEye's site, get a shared view of conversion leaks and infrastructure blind spots across locations. Store managers get hourly alerts when cameras or networks drop so footfall data does not silently go missing.

Double is a lead research and enrichment platform for sales and marketing teams. You upload a prospect list, and Double uses GPT to search the web and answer custom questions about each company or contact. Instead of manually Googling accounts, you define the criteria that matter to your outbound motion and get answers back at scale.

The product focuses on qualifying and enriching leads in bulk. You can ask whether a company is remote-first, SOC II compliant, B2B, building an API product, running a marketplace with payments, or shipping a mobile app as its core offer. Double returns sourced answers you can review alongside LinkedIn and email data in a table view.

Double also finds verified work emails by aggregating more than ten private data sources. The site positions this coverage as broader than tools like Apollo and RocketReach. Teams at Amazon, Indeed, and Gartner are shown on the homepage, and the company is backed by Y Combinator.
