With over 30 years in wireless—from helping pioneer intercarrier SMS to running mobile identity operations across Americas and Asia Pacific — Eddie DeCurtis saw what others missed: 967 of 1,000 global mobile network operators lack the infrastructure to monetize CPNI data while protecting customers from fraud. The technical challenge isn't building APIs. It's that operators spent billions on 5G infrastructure and now lack capital, internal expertise, and operational frameworks to launch authentication services. In 18 months, Shush went from PowerPoint to 30 employees, supporting 47 network APIs with full GSMA Open Gateway compliance. Eddie shares how understanding regulatory frameworks by jurisdiction, not just deploying technology, became their competitive moat—and why hiring the executive who built T-Mobile USA's authentication platform gave them credibility no competitor could match.

Topics Discussed:

• Why operators repeatedly said "we want to do it, we have no idea how, we have no money, we don't have a platform"
• Validating the thesis with former AT&T Communications CEO John Donovan before launching
• Securing a POC with a major operator pre-incorporation—with only a PowerPoint deck
• The three-legged stool: technology, network integration, and business operations (where competitors fail)
• Why knowing privacy regulations for CPNI data sharing by country became a deal-closer
• Reducing network integration from dozens of touchpoints to three specific network elements
• Supporting 8 Linux Foundation Camara APIs and TS.43 GBA AKA authentication standard
• Going from 3 to 30 employees and launching at Mobile World Congress on a $75/night Airbnb budget

GTM Lessons For B2B Founders:

• Validate with the person most likely to kill your idea: Eddie deliberately chose John Donovan—former CEO of AT&T Communications, board member at Lockheed and Palo Alto Networks—specifically because "he's going to be rough, he's going to totally ask the really hard questions." When Donovan's response was "go raise $40 million and own this space...you're not going to be alone for long," .
• Convert pre-product conviction into design partner commitments: Eddie secured a POC agreement with a major operator before Shush incorporated. "I had nothing. I didn't have software. We had an idea, we had a PowerPoint presentation." This only works when you've spent decades building domain expertise and relationships.
• The enterprise moat is operational knowledge, not technical capability: Eddie's thesis: "Anybody can come up with the technology. You walk down the street in the Bay Area, 10 developers will develop it for you." Shush differentiated by answering questions competitors couldn't: How do you price SIM swap detection per query? What are CPNI data sharing regulations in Indonesia versus Brazil? When Eddie told an operator "here's the privacy rules for your country" after they admitted "I have no idea,".
• Target the ambition-capability gap in capital-constrained buyers: Operators told Eddie the same story: eager to launch authentication services, zero clarity on execution, budgets decimated by 5G spending. This created perfect conditions for a full-stack solution. "Mid-market is hard because you have a buyer with problems that are not basic anymore, but they lack the ability to execute."
• Hire the operator who ran your exact use case at scale: Eddie cold-called John Morrowton, who "built this actual product and service offering at T-Mobile USA, from its inception to its execution and ran it for four years." His pitch: "I'm Eddie DeCurtis, how are you? You want a job? You're Chief Product Officer."
• Minimize integration surface area to accelerate deployment: Mobile operators run highly secure networks with limited external access points. Shush "narrowed it down to three network elements that we can communicate with to provide all 47 APIs." Fewer integration points means faster deployment, lower implementation risk, and reduced operator IT overhead.
