Founding Customer Success Lead

About SpangleAI
Launched in 2025, Spangle AI helps enterprise retailers win AI-driven product discovery, connecting discovery to conversion. We've partnered with enterprise brands like REVOLVE, Alexander Wang, and Steve Madden, delivering up to 50% conversion lifts and 2x ROAS improvements.
Spangle creates commerce experiences around customer intent. Generic AI knows the internet. Spangle knows your brand.
Backed by top tier VCs with $21M in funding, Spangle is founded by serial entrepreneurs with 30+ years scaling AI and commerce at Amazon, Saks, and Gap, we're building the commerce infrastructure for the agentic era, where ChatGPT Shopping, Google AI Overviews, and Meta are reshaping how consumers discover and buy.
Spangle won NRF’s VIP (Vendor in Partnership) Award for Best AI-Driven Marketing Solution and was recognized in Business of Fashion’s AI startups to Watch within its first year of launch.
The Role
We’re looking for a Founding Customer Success Lead to help our customers become long-term strategic partners: partners who grow with us, happily recommend us, and help shape where the product goes next. Onboarding, QBRs, adoption, and health scoring all support that bigger goal.
At its heart, this role is about helping customers get so much value from Spangle that growing with us feels like the natural next step. If we get it right, our customers become our biggest advocates and our most valuable source of product insight.
You’ll join a small team of experienced senior leaders who have built and scaled companies before, and you’ll have a real seat at the leadership table. Your perspective will help shape company strategy, the product, and how we go to market. This goes well beyond account management. Every customer who expands with us strengthens our position, every reference makes the next conversation easier, and every customer insight makes the product better. You’ll be a core part of both our go-to-market team and our product feedback loop, and you’ll help shape how one of the first AI-native enterprise software companies is built.
What You'll Own
Enterprise account relationships. Build close relationships with the VP of Ecommerce, CMO, or CDO at each customer. You’ll be a trusted advisor they rely on, not just a vendor contact.
Land & Expand. Help customers bring Spangle to more of their commerce surfaces as they grow with us, building long-term partnerships one account at a time.
Reference customer program. Partner with customers on case studies, co-marketing, and speaking opportunities at events like Shoptalk, NRF, and BoF VOICES.
Renewal and retention. Own the renewal calendar and build an early-warning system so we can support customers before issues arise. We’re proud to have zero churn, and you’ll help keep it that way.
Customer voice into product. Work with product leadership to turn customer feedback into product priorities. Host quarterly customer advisory sessions.
Onboarding and sales-to-CS handoff. Design a smooth handoff from Sales and build our onboarding playbook, helping customers move from POC to launch to expansion-ready in just weeks.
Measurement. Build our customer health scoring and a weekly customer dashboard that gives the CEO and leadership team a clear picture.
Required.
What We're Looking For
6+ years in B2B SaaS customer success, including the last 3–4 managing enterprise accounts with expansion goals.
Experience personally managing a $5M+ ARR book, with expansion results you’re proud of.
A track record of growing accounts, not just retaining them. We’d love to hear the specific numbers.
Strong commercial instincts across pricing, renewals, and building expansion cases.
Relationships with enterprise commerce or retail leaders (VPs of E-commerce, CMOs, CDOs), or a clear 90-day plan for building them.
You use AI every day. Claude, GPT, Perplexity, or similar tools are part of how you work, and you enjoy walking people through the automations you’ve built.
You’re a natural partner to founders and senior leaders. You bring the customer’s voice into the company with clarity and focus, and you bring your own perspective to leadership conversations.
Ideal.
A background at a digital agency (in marketing or analytics roles), or at an AI-native or modern B2B SaaS company (Snowflake, Datadog, MongoDB, Stripe, Klaviyo, Attentive, Linear, Vercel, Notion).
Experience in commerce or retail tech, ideally with exposure to contemporary or mass market retailers and the brands that sell to them
Founding CS hire at a company that grew from $0 to $20M+ ARR.
Comfort with measurement. Familiarity with Gainsight or similar tools is great, though you might enjoy building something custom even more.
