Frequently Asked Questions
Is Nektar a replacement for Cirrus Insight?
It depends on what you use Cirrus Insight for. Cirrus Insight is a broad Salesforce productivity platform that includes Salesforce Sync, Sidebar, scheduling, Buyer Signals, Conversation Intelligence, and other sales productivity capabilities. Its Salesforce Sync automatically captures email, calendar, and task activity. Nektar is focused specifically on the revenue data layer capturing activity, identifying stakeholders, connecting them to Opportunities, and creating structured Salesforce data. If you primarily need an inbox productivity platform, Cirrus Insight may be a fit. If you need complete Salesforce activity, stakeholder, and buying-group intelligence, Nektar is built for that.
Does Cirrus Insight support historical backfill?
Yes. Cirrus Insight offers Historical Sync, which can capture historical inbox activity into Salesforce for a specified period. Cirrus directs customers to inquire for details about the service. The more useful comparison is how historical activity is backfilled, attributed, and incorporated into the broader Salesforce relationship picture.
Does Cirrus Insight support custom Salesforce objects?
Yes. Cirrus explicitly says its sync supports custom objects, fields, related objects, and tasks. Smart Link can associate activity with Salesforce objects including Opportunities, Cases, and custom objects.
Does Cirrus Insight sync email and calendar activity?
Yes. Cirrus says it syncs emails, calendar events, including invitees, and tasks directly to Salesforce. Its Calendar Sync also supports recurring events, historical record sync, and custom sync windows.
Does Cirrus Insight support multiple Opportunities?
Cirrus supports Opportunity association through Smart Link and rules-based matching. For teams with multiple active Opportunities at the same account, the important evaluation is how the system determines which Opportunity an interaction belongs to, rather than simply whether Opportunity syncing exists. Nektar uses contextual relationship inference to associate activity with the appropriate Opportunity.
Does Cirrus Insight create Salesforce Contacts?
Cirrus supports working with Salesforce Leads and Contacts from its inbox experience and automatically syncs email activity to the appropriate Contact or Lead. Nektar goes beyond activity association by identifying previously unknown stakeholders and creating the corresponding relationship records as part of its buyer-group intelligence.
Does Nektar create Opportunity Contact Roles?
Yes. Nektar can create and maintain Opportunity Contact Roles (OCRs) so that stakeholders discovered through email and calendar activity become part of the Opportunity's structured buying-group data.
Can Nektar and Cirrus Insight be used together?
Potentially. If both systems are capturing the same email and calendar activity, however, teams should carefully evaluate synchronization rules and deduplication to avoid duplicate Salesforce activity. For organizations using Nektar as the primary revenue data layer, the cleaner architecture is generally to establish a clear system of record for activity capture.
What makes Nektar different from an email sync tool?
An email sync tool answers: “How do we get activity into Salesforce?”
Nektar asks a larger question: “How do we turn all of that activity into complete, structured revenue context?”
That means connecting the people, accounts, Opportunities, activities, and buying groups involved in every deal. The result is a Salesforce data foundation that gives RevOps, Sales, and AI systems the context they need to understand what is actually happening across the revenue cycle.
Is Nektar the right fit for me?
Nektar is built for teams that need more than email and calendar activity in Salesforce. If your only requirement is to sync messages and meetings into Salesforce, Nektar may offer more functionality than you need. The value comes when you need the people, relationships, and Opportunity context behind that activity, and want that information structured in Salesforce as part of your GTM data foundation. If basic activity capture is the entire job, a simpler sync tool may be enough. If understanding who is involved in your deals and how that activity connects to revenue matters, that's where Nektar earns its place.
Which is better for AI-ready Salesforce data?
For basic activity capture, both platforms can contribute data to Salesforce. But AI needs more than a larger activity log. It needs accurate relationships between people, accounts, Opportunities, activities, and buying groups. Nektar is built around creating that structured context directly in Salesforce.
Does Nektar require reps to change how they work?
No. Nektar captures email and calendar activity in the background, so reps don't need to manually log every interaction or adopt a new workflow.
Why switch from Cirrus Insight to Nektar?
The strongest reason to switch is if your requirements have moved beyond activity synchronization. Nektar is designed for organizations that need Salesforce to become a complete revenue data foundation. One that captures not just what happened, but who was involved, which deal it relates to, and what that means for the buying group.
