What ProtoPie does
ProtoPie (legally Studio XID Korea, Inc.) is a Seoul-headquartered B2B SaaS company founded in 2014 that builds a high-fidelity interaction design prototyping platform. Its core product, ProtoPie Studio, is a desktop application for macOS and Windows that lets designers assemble interactive prototypes using variables, formulas, conditional logic, and multi-device flows without writing code. The platform is complemented by ProtoPie Player (a companion app on iOS, iPadOS, Android, and Wear OS for testing prototypes on real hardware), ProtoPie Cloud (web-based storage, sharing, and developer handoff), and ProtoPie Connect (an add-on that links prototypes to Arduino, gamepads, automotive hardware including Logitech G29, IFTTT, Unity, and external APIs). ProtoPie has been granted 20+ patents across the US, South Korea, Japan, and China protecting its prototyping technology.
The company monetizes through a four-tier subscription model (Free, Basic, Pro, Enterprise) sold via a hybrid go-to-market that pairs a true freemium, self-serve download with an enterprise sales motion targeting large design and product teams. Enterprise plans bundle SSO/SAML, dedicated CSM, advanced permissions, and Connect Core/Enterprise. Customer logos span Meta, Microsoft, Google, BMW, Mercedes-Benz (via MBition), Warner Bros. Discovery, and Picsart, with vertical emphasis on automotive HMI, finance/fintech, IoT/connected devices, and digital product teams. Supporting ecosystem includes ProtoPie School (free learning platform), ProtoPie AI (a Human-in-the-Loop generative feature in Open Beta since February 2026), an Agency Partner Program (Silver/Gold/Platinum), and a 40% affiliate channel. The company has raised approximately $29M across multiple rounds, most recently a $21M Series B in January 2025 co-led by LB Investment and Korea Development Bank, and operates with ISO 27001 and ISO 27701 certifications.

ProtoPie competitors and assessment
Company assessmentDirect peers
- Figma: Figma is the dominant collaborative design platform with built-in prototyping features that compete directly with ProtoPie's core offering. Both target product designers and integrate with each other via ProtoPie's Figma plugin, indicating overlapping use cases for interactive prototyping.
- Adobe XD: Adobe XD is Adobe's design and prototyping tool that competes in the same interactive prototyping category. ProtoPie maintains a native import plugin for Adobe XD, signaling overlapping customer workflows and direct feature competition.
- Sketch: Sketch is a major macOS-based design tool with prototyping capabilities, and ProtoPie maintains a native import plugin for Sketch. Both target product/UI designers building interactive prototypes from design assets.
- Axure: Axure is a long-standing high-fidelity prototyping tool used for complex, logic-driven interactive prototypes. It overlaps with ProtoPie in the advanced-prototyping niche, particularly for enterprise UX teams that require conditional logic and dynamic data flows.
- Framer: Framer is a design and prototyping platform with built-in code publishing and AI-assisted site generation. It targets the same product designer base as ProtoPie and is increasingly competing in the advanced-prototyping and AI-assisted design space.
- InVision: InVision was a pioneering prototyping and collaboration platform for design teams and competes directly with ProtoPie on interactive prototyping. Although it has narrowed its offering, it remains a reference point in the advanced-prototyping category.
- Justinmind: Justinmind is an interactive prototyping tool for web and mobile apps, targeting enterprise UX teams. It overlaps with ProtoPie on high-fidelity prototyping, UI simulation, and developer handoff workflows.
- Balsamiq: Balsamiq is a wireframing and low-fidelity prototyping tool for product designers and product managers. While lower-fidelity than ProtoPie, it competes for the same designer budget and on-ramps users toward higher-fidelity tools like ProtoPie.
Emerging players
- Principle: Principle is a macOS prototyping tool focused on animated, multi-screen interactions. It overlaps with ProtoPie's interaction/animation capabilities and serves a similar advanced-prototyping niche, though with a narrower multi-device/HMI scope.
- Origami Studio: Origami Studio is a free prototyping tool from Meta focused on advanced, logic-driven interactions. It competes with ProtoPie in the high-fidelity interaction design space and is used internally at Meta — one of ProtoPie's named customers.
