Why SubBase's founder still listens to every sales and support call | Eric Helitzer

Eric Helitzer is the Founder and CEO of SubBase, a B2B vertical SaaS platform giving construction subcontractors and self-performing GCs a system for managing materials, a workflow historically run on email, text, and phone calls. Eric returns to BUILDERS to unpack an ICP that emerged on its own, the "AI wrapper" defensibility question he faced at Series A, and how he stays embedded in sales and support at scale. Topics Discussed: How self-performing GCs became a fast-growing segment SubBase never originally targeted Why paid social and paid advertising failed to convert in a relationship-driven buying process A phone-first, discovery-led outbound motion and the signal used to separate real pipeline from booked meetings Defining the category as a materials operating system rather than a point solution Why "is this just an AI wrapper" was the core Series A defensibility question, and how Eric answered it Staying embedded in sales and support detail as the company scales past founder-led selling GTM Lessons For B2B Founders: Let adjacent ICPs surface through usage, not planning: Self-performing GCs, contractors who take on their own labor and material risk instead of subcontracting it out, were not a segment SubBase set out to sell. Eric called it "our newest, not a new ICP, but one that we've seen gravitating towards us." Overlap in workflow with existing customers made the expansion visible before it became a strategy. Qualify for pain on the call, not after it: SubBase reps diagnose the prospect's actual procurement pain during the cold call itself, not just book time. Eric's bar for a correctly pain-funneled call is simple: does the prospect show up to the follow-up meeting. "If that person shows up on a call, that's real pain." A no-show is coaching data on messaging, not a scheduling problem. Defensibility in an AI-native narrative sits in the data layer, not the workflow: Series A investors pushed on whether SubBase could be replicated as a thin AI wrapper. Eric's answer centered on proprietary data from vendor communication, pricing, and reconciliation across a fragmented industry, something "you can't just rip off of a Claude or GPT." When your workflow looks simple, your case has to rest on compounding data, not interface. Separate the investor narrative from the customer narrative on purpose: Framing SubBase as an "operating system" answered investor questions about moat. But construction buyers aren't shopping for an OS, they want one acute pain solved.
