David Kim

Notion

Head of RevOps

SalesforceSegmentMixpanel
95/100

David, with Notion's conversion funnel from individual to team plans, I'm curious how you're currently tracking which product behaviors in Mixpanel actually predict enterprise expansion.

81/100

Your PLG motion is converting users to paid, but I'd guess the bigger RevOps challenge is predicting which team accounts will hit the expansion threshold before they churn.

87/100

Most all-in-one platforms struggle with one thing: connecting usage data back to Salesforce before the sales team loses context—curious if that's on your roadmap.

Noah Lindberg

Canva

VP Sales, Enterprise

SalesforceOutreachSegment
91/100

Noah, your enterprise expansion is clearly working—curious if you're seeing Salesforce pipeline velocity challenges as your team scales past traditional design use cases.

95/100

With Canva's enterprise motion, I'd imagine your Outreach sequences need to differentiate between design teams adopting vs. broader org adoption—worth a quick conversation?

91/100

Most enterprise sales teams use Segment to track product adoption, but design tools rarely connect usage patterns to account expansion—might be a gap worth exploring.

Daniel Silverstein

Brex

VP Revenue

SalesforceOutreachGong
88/100

Daniel, your Outreach deployment suggests you're tracking sales velocity closely—curious how you're measuring adoption ROI on new Brex features with your enterprise segment.

84/100

With Gong recording your sales calls, you're likely seeing patterns in what resonates with CFOs on card controls and reconciliation—what's the biggest objection you're still hearing?

95/100

Your Salesforce integration probably shows which customer segments are expanding fastest through Brex's spend management tools—are mid-market SaaS companies outpacing your original startup focus?

Tariq Hassan

Lattice

Head of Growth

HubSpotMarketoSegment
86/100

Tariq, most performance management platforms track employee data but struggle to activate it—curious if Lattice is seeing the same gap between what your customers measure in Marketo and what actually drives engagement outcomes?

86/100

Your customers are likely syncing employee performance data through Segment, but can't easily action it across their existing HR workflows—does that friction show up in your churn conversations?

95/100

Given Lattice's positioning on engagement, how are your mid-market customers typically connecting performance insights from your platform back into their existing HubSpot and recruiting processes?

Alexander Petrov

Greenhouse

VP Sales

SalesforceMarketoOutreach
92/100

Alexander, your Outreach sequences likely capture candidate pipeline velocity, but most hiring teams still lose 30% of candidates between phone screen and offer—curious how Greenhouse is solving for that handoff.

92/100

Given Greenhouse's focus on structured hiring, I'd guess your Salesforce integration is managing recruiter workflow, but candidate experience typically breaks down when scheduling and feedback loops aren't synchronized.

95/100

Your Marketo campaigns probably drive recruiter adoption well, but the candidates entering Greenhouse usually experience fragmented communication across 4-5 different tools—worth a 15-min conversation?

Naomi Friedman

Intercom

VP Growth

SalesforceMarketoSegment
91/100

Your AI agents are handling support tickets, but I'm guessing your team is still manually routing conversations through Salesforce based on rules that change weekly.

95/100

Intercom's pivot to AI support means your conversion funnels are probably generating way more qualified leads than your Marketo workflows can segment in real-time.

88/100

If your AI agents are pulling customer data from Segment, you're likely leaving conversion opportunities on the table by not feeding intent signals back into your sales stack.

Yuki Sato

Pendo

Head of New Business

SalesforceMarketoOutreach
95/100

Your Marketo setup is driving demand, but I'm curious how Pendo's product teams are tracking which features actually drive expansion revenue.

92/100

Most teams using Outreach to scale sales miss the signal that's already in their product—wondering if you're seeing gaps between what Pendo guides users toward and what actually converts.

86/100

With Salesforce as your source of truth, you're probably managing multiple product initiatives—does your team have visibility into which ones users are actually adopting before the sales cycle closes?

Thea Andersen

LaunchDarkly

Enterprise AE

SalesforceOutreachGong
95/100

Thea, most Enterprise AEs using Outreach are managing feature rollouts manually across accounts—I'm curious how LaunchDarkly handles that complexity at your scale.

87/100

Your Salesforce integration probably surfaces a lot of deployment data—do your customers ever struggle to connect release velocity back to their actual revenue impact?

87/100

With Gong recording your customer calls, you're likely hearing repeated questions about safe rollout strategies—is that something your prospects ask about in discovery?

Asha Ramaswamy

Hugging Face

Head of Partnerships

HubSpotSlackGitHub
95/100

Your GitHub integration lets teams version control models, but I'm curious how you're thinking about standardizing model cards across the 500K+ repos on Hugging Face.

92/100

Most ML teams we work with struggle to keep their Slack channels synced with actual model updates—how do you see collaboration workflows evolving as more enterprises adopt Hugging Face?

87/100

HubSpot tracks partner engagement, but measuring actual model adoption and usage patterns across your community seems like a different problem entirely—what's your current approach?
