Nectar’s solutions integrate with the HR tools your teams already use, including Teams, Slack, Outlook, and your HRIS software helping you create the ideal workplace that people don’t want to leave. NECTAR RECOGNIZE Recognition isn't just a nice-to-have. Nectar Recognize provides recognition features that reduce turnover, boost morale, and give your people a reason to stay engaged every single day. Functionality includes: peer-to-peer shoutouts, rewards library, challenges, automatic milestones and anniversaries, community recognition, and nominations. With a complete mobile app and flexible login options, Nectar makes it easy for deskless workers to recognize peers and claim rewards. All recognition is tied to your organization’s mission and values, building trust and confidence in your company’s unique differentiators. Automated milestone recognition also ensures no important date, like birthdays and work anniversaries, goes unnoticed. Managers and admins use built-in analytics to view participation rates, value alignment, recognition patterns, and redemption trends. Spot disengagement early and see concrete, measurable ways to help employees feel genuinely valued. With 85% user adoption, Nectar’s tools make it convenient for every employee to celebrate and recognize one another. NECTAR COMMS The right internal communication program prevents teams from feeling disconnected and uninformed. Nectar Comms combines company messages, bridges gaps between remote and in-office employees, and keeps everyone in the loop. Deliver announcements and updates exactly where people will see them. Choose SMS, email, Slack, Microsoft Teams, or even Nectar itself. By using Nectar to deliver your internal newsletter, people stay in the loop without having to check extra tools. Leaders get real-time visibility into who’s receiving and reading updates, eliminating the guesswork of whether critical messages are actually being seen. No wondering if important announcements vanish into a black hole. NECTAR ENGAGE Without employee listening software, you don’t what’s really going on inside your organization. Use Nectar Engage to gather honest feedback through convenient surveys, pulse check-ins, and eNPS. Reward Nectar points for completing surveys so you capture more representative data. Deliver surveys and reminders through SMS, email, Teams, Slack, and Nectar. As responses come in, track quantitative and qualitative sentiments and spot clear patterns before they become issues that drive employees away. Even ask questions about anonymous survey responses so you gather the full context — without forcing team members out of anonymity.

Bring them together with Nectar’s Culture Suite and you build a healthy organization with concrete proof of connection and engagement. Connect feedback with genuine appreciation and share results and action plans. With Nectar’s integration solutions, recognition happens regularly and naturally in the flow of work. And it doesn’t have to happen at a desktop computer. Admins customize programs by team, location, or brand and make decisions based on real participation and feedback, not guessing what employees care about.
