Stephanie designs AI interfaces
I build agentic products across prompts, memory, orchestration, and user-facing interfaces. Previously at Sigma, Tulip Interfaces, and Samsung. Based in the Bay Area, usually designing, plant-hunting, powerlifting, or sourcing seasonal finds at Trader Joe’s.
Founding product designer,
Seam AI
Seam AI is an AI-native Account Based Marketing platform that orchestrates and automates sales and marketing workflows. Seed round led by Bessemer Venture Partners.
Agent Stitch
Shipped the harness for a GTM agent built on Claude Managed Agents. I led decisions end-to-end across product infrastructure (system prompt, per-tenant memory and skills) to shape the agent's behavior, while also defining the core user experience for a non-chat agent interface.
Workflow orchestration
Transformed complex and disconnected workflows into an opinionated orchestration system with ready-to-use, customizable flows. Made sophisticated automation accessible to non-technical GTM teams without sacrificing power-user capabilities.
ABM Stages & Intelligence layer
Visualized the intelligence layer atop our data model with transparent scoring and intent surfaces. Made AI decision-making visible and actionable by opening the black box, increasing user trust.
Fit score agent
Designed the market's first customizable AI fit scoring, breaking legacy tools' rigid, black-box approach. Users backtest scoring logic before running full research, see why accounts match their ICP, and compare multiple scores.
Product designer,
Sigma Computing
Sigma Computing is a cloud-based BI and analytics platform that enables business users to explore data without code, also described as "Excel on steroids." Sigma reached $100M ARR in 2025.
Workbook exploration
Led end-to-end design for the entry point, configuration modal, and results view for removing duplicate rows in workbook tables. Reduced clicks by 92% and resolved pain points reported by 32 customer orgs.
Multi-tenancy management
Designed and shipped matti-tenancy design. Enable tenants to work independently with their own data and permissions, while maintaining centralized governance and visibility.
Sigma’s first user-facing design system
Created Sigma's first end-user design system, enabling users to build accessible, user-friendly data apps directly in the product. Established patterns and components that scale across diverse use cases.
Product designer,
Tulip Interfaces
Tulip Interfaces is a low-code app platform for manufacturers that connects people, machines, devices, and systems in production processes.
Admin dashboard & iOS App
Led end-to-end design of the admin dashboard, improving efficiency through enhanced navigation, faster information access, and streamlined key actions. Also contributed to iOS app improvements for frontline worker mobile deployment.
Interaction designer,
Samsung Research
Neon is an artificial intelligence project backed by Samsung's STAR Labs, focused on creating interactive, human-like digital avatars that feel present and responsive.
Neon Assist for healthcare
Designed a virtual human assistant that streamlined meal ordering for hospital patients, partnering with Aramark Healthcare to deliver a smooth, empathetic experience in clinical settings.
Product builder,

Chromia
Designed and coded an end-to-end product, Chromia. An iOS app for noticing color in the world, privately archiving it, and trading postcards with strangers who noticed too.
Palette Plate
Built an innovative kitchen gadget that revolutionizes plating by combining a Raspberry Pi, projector, camera, and AI (GPT-3.5, Foodvisor, YOLOv8).
