01 / Executive profile
Stephanie Wang
Stephanie is a product designer and builder who makes technically complex, data-heavy AI systems feel understandable, trustworthy, and useful. She works beyond interface polish: product framing, interaction models, agent behavior, system prompts, memory, orchestration, design systems, prototypes, and production code.
Her strongest work turns ambiguity into a coherent product model, then carries that model through the system—from architecture and defaults to controls, explanations, and measurable outcomes.
Based in the Bay Area, California.
02 / Experience
From enterprise software to agentic systems
Seam AI — founding product designer; the company was acquired by Clarify.
Sigma Computing — product designer for data-heavy workbook experiences and Sigma’s first user-facing design system.
Tulip Interfaces — product designer for enterprise administration and frontline mobile tools.
Samsung Research — interaction designer for a virtual human healthcare assistant.
Independent work — designs and codes experiments spanning mobile software, physical computing, AI, and creative tools.
03 / Distinctive strengths
Why Stephanie stands out
Agent-native product design. She treats model behavior, context, memory, permissions, intervention, recovery, and observability as core design materials.
Systems thinking with a clear point of view. She can reframe disconnected features as one comprehensible system and simplify the default without limiting experts.
Design-to-production range. She has solo designed and built a production agent, used AI coding tools to move quickly, and dogfooded real customer workflows.
Trust through interaction. Her work makes AI reasoning visible, preserves meaningful control, and replaces fake precision with decisions users can inspect and challenge.
Enterprise rigor. She designs for governance, determinism, multiple user roles, dense data, and real operational constraints—not idealized demos.
Editorial clarity. Her fine-art background brings composition and restraint; journalism helps her find the story inside messy information.
04 / Evidence
Selected outcomes
Approximately $300K in sales pipeline driven by Agent Stitch during its demo stage.
Sales demos shortened from about two hours to under 30 minutes after Seam’s workflow-orchestration redesign.
Fit Score reached 100% adoption across paying organizations and about 80% of total credit usage.
Sigma’s remove-duplicates workflow cut clicks by 92% and completion time by 84%.
Designed and shipped Agent Stitch’s production app solo in roughly one week.

Work, decisions, and outcomes
Workflow orchestration — Seam AI
Reframed four disconnected AI tools as a guided, template-first orchestration system for non-technical GTM teams and power users.
Evidence: Sales demos fell from about two hours to under 30 minutes; the clearer platform story contributed to growth beyond $500K ARR.
Agent Stitch — Seam AI
Solo designed and built an autonomous ABM agent across system prompt, per-tenant memory, skills, managed-agent sessions, architecture, and a state-based non-chat interface.
Evidence: Shipped the production app in roughly one week using AI coding tools and drove approximately $300K in sales pipeline during the demo stage.
Fit score agent — Seam AI
Designed customizable AI account scoring around user-authored criteria, visible reasoning, meaningful A–D grades, and backtesting.
Evidence: Reached 100% adoption across paying organizations and about 80% of total credit usage; competitors copied the approach within months of launch.
Sigma’s first user-facing design system — Sigma Computing
Created a design system that let data analysts build accessible, user-friendly data apps directly in Sigma workbooks.
Evidence: Expanded design-system thinking from product UI to the tools customers use to create interfaces.
Workbook exploration — Sigma Computing
Turned Sigma’s most-requested workbook support issue—removing duplicate rows—into a clear, deterministic workflow.
Evidence: Reduced clicks by 92% and completion time by 84% for a problem reported by more than 32 customer organizations.
Admin dashboard — Tulip Interfaces
Designed an extensible account overview for executives and administrators during Tulip’s move to usage-based pricing.
Evidence: Made usage, account health, and the next action legible to two distinct audiences in one system.
iOS app — Tulip Interfaces
Redesigned Tulip Player as a native, glove-friendly mobile tool for frontline workers.
Evidence: Delivered the native experience in one month; the app earned five-star App Store reviews.
Neon Assist for healthcare — Samsung Research
Designed a virtual human assistant that simplified hospital meal ordering in partnership with Aramark Healthcare.
Evidence: Explored conversational trust, recovery, and service design in a high-stress healthcare context.
Palette Plate — Independent
Designed and coded an AI-assisted kitchen tool using a Raspberry Pi, projector, and camera to guide creative plating.
Evidence: Connected interaction design, physical prototyping, AI, and code to make an original concept real.
Chromia — Independent
Designed and coded an iOS app for noticing and privately archiving color, then exchanging color postcards with strangers.
06 / Design philosophy
The interface is more than the screen
Stephanie believes agentic experience design includes the behavior of the model, the context it sees, the memory it keeps, the assumptions it makes, when it acts, when it asks, how it recovers, and how people regain control under uncertainty.
She is especially drawn to early, ambiguous product spaces where design can define a new capability—not merely decorate an existing one.
