As answered by people managing Popl and Nullstack.
Popl's answer
Most event teams leave a show with a stack of business cards and days of waiting for the organizer’s lead list. Popl closes that gap. Our AI-powered Universal Badge Scanner reads any event badge, business card, or QR code, enriches each contact, and syncs it to your CRM in seconds, even when venue WiFi is unreliable, with data auto-syncing once you’re back online. Your team owns every lead the moment it’s captured and follows up while the conversation is still warm.
Popl's answer
Our mobile app is built in React Native, with native Swift for iOS and native Java for Android, and our web dashboard runs on React. The backend uses Node.js, TypeScript, AWS and Google Cloud, SQL, and RESTful APIs, alongside Firebase. AI-powered enrichment draws on B2B data from 20+ trusted data partners, and everything is secured with SOC 2 Type II controls and encryption at rest and in transit.
Popl's answer
Speed to follow-up drives event ROI, and Popl is built around it. Instead of a different scanning app at every show, your team gets one consistent system at every event, with leads landing in Salesforce, HubSpot, Zoho, or Dynamics already enriched and qualified. Managers get group billing, templates, and team-level CRM connections, IT gets SOC 2 Type II security, and everyone gets 24/7 global support. That’s why over 90% of Fortune 500 companies trust Popl.
Popl's answer
Popl is built for B2B teams that rely on in-person events for pipeline: companies that attend multiple conferences and trade shows a year and run on a CRM. That includes field sales and event marketers capturing leads on the floor, RevOps teams who need clean data and attribution, IT leaders focused on security and integrations, and executives who want proof that events drive revenue. We serve everyone from growing SMBs to global enterprises.
Popl's answer
Popl launched in 2020 on a simple belief: life is exciting, and work should be too. Our digital business card went viral on TikTok and Instagram, and we joined Y Combinator’s W21 batch and raised $3M. As teams adopted Popl, we saw a bigger problem: in-person leads were getting lost, delayed, or locked up by event organizers. So we launched Popl Teams in 2024, then our Event Lead Capture platform and AI-powered Universal Badge Scanner in early 2025. Today, 2.5M+ users in 150 countries use Popl, including our own sales team at every conference.
