The old adage that "it's not what you know, it's who you know" has found its algorithmic expression in Centralize, a San Francisco startup that just closed a $15 million Series A round to help sales teams navigate the Byzantine world of B2B relationship mapping.
NEA led the financing, as noted in the Axios Pro Rata newsletter, with participation from Salesforce Ventures, Y Combinator, 20SALES, Ritual Capital, and Adverb Ventures. The round brings Centralize's total funding to $19 million since co-founders Rachit Kataria and William Wang launched the company in 2023—though the pace of recent growth suggests they're moving faster than even they might have anticipated.
Operating formally as Collate Labs, Inc., Centralize builds what it calls "AI agents for relationship selling." In practice, that means software that automatically maps the sprawling cast of characters involved in complex enterprise deals: the champions, the influencers, the budget holders, and—crucially—the blockers who can torpedo a six-figure contract with a single email to the CFO.
The Problem of the Ever-Expanding Buying Committee
Anyone who's sold software to large organizations knows the challenge. A deal that starts with an enthusiastic VP of Engineering can stall when IT security gets involved, or when procurement decides to loop in legal, or when a new stakeholder emerges from a department you didn't know existed. Salesforce Ventures noted when it led Centralize's earlier seed round that enterprise deals now routinely involve ten or more decision-makers.
Perhaps more frustratingly, the buyer landscape shifts constantly. People change roles, new executives join, reorganizations shuffle reporting lines. Traditional CRM systems capture what happened—who attended which meeting, who opened which email—but they don't automatically connect the dots or flag when your champion just lost budget authority.
Centralize's platform pulls data from emails, calendars, recorded calls, CRM systems, and users' professional networks to generate what the company describes as "always-updated relationship maps." It also surfaces warm introduction paths through executive, investor, and advisor networks—the kind of intelligence that can turn a cold outreach into a trusted referral.
The company integrates with the usual suspects: Salesforce, Google, Outlook, Slack, Gong. It maintains SOC 2 Type 2 certification, the enterprise security credential that's become table stakes for any SaaS vendor hoping to close Fortune 500 deals.
Early Adopters and Early Returns

Centralize's customer roster includes Intercom, Brex, Highspot, Metronome, Cresta, Sendoso, Navattic, Ethena, and Arkose Labs—mostly growth-stage companies familiar with the ROI math on sales efficiency tools. According to early metrics shared by Salesforce Ventures and company testimonials, SDRs using the platform saw response rates double, while account executives reported reclaiming five or more hours per week previously spent on manual relationship research.
Whether those gains hold as the platform scales beyond early adopters remains to be seen, but the customer mix suggests product-market fit within a specific segment.
A Team Built for This
The founding team's pedigree runs through the usual Silicon Valley proving grounds. Kataria spent time as a founding engineer on Facebook Shops before joining AtoB, a Y Combinator-backed fintech, as a product tech lead. Wang helped start Slack's prototyping team and led the initial launch of Slack Huddles—that feature now so ubiquitous in remote work that it's easy to forget it was once a risky product bet.
Both studied computer science at USC. Both, it seems, understand the unglamorous reality that most enterprise software success comes down to workflow integration and data quality rather than flashy AI demos.
The company graduated from Y Combinator's Winter 2024 batch and raised a $4 million seed round led by Salesforce Ventures not long after. In a recent LinkedIn post, Kataria indicated the team had nearly doubled—from nine people to almost 20—in a single month. That kind of sprint hiring often signals either aggressive sales expansion or preparation for a major product push.
A Category Heating Up

Centralize enters a relationship intelligence market that's seen waves of funding and consolidation over the past few years. Introhive and Affinity have raised substantial venture rounds. Revenue intelligence platforms like People.ai continue layering on AI capabilities. A Gartner survey from earlier this year found that sales organizations providing AI-enabled "Next Best Action" guidance are 2.6 times more likely to hit growth targets—the kind of stat that gets circulated in board decks and VP-level Slack channels.
The category hasn't yet produced a clear winner, which is both opportunity and warning. Centralize's bet is that relationship mapping—what Y Combinator describes as "the graph of who trusts who in B2B"—becomes foundational infrastructure rather than a nice-to-have feature buried in a larger platform.
For now, at least, investors are willing to back that thesis. Whether enterprise sales teams adopt it as broadly as their CRMs and email tools is the $15 million question.
