What it is

Kevin Tenn’s website is a personal portfolio and contact point for a product designer / design engineer, rather than a standardized design tool or asset platform. The page states that he is based in Los Angeles and has around 10 years of experience across startups and enterprise environments. He has worked on product design, front-end implementation, design systems, and complex business tools at companies such as Instacart, Meta, and Ring, and is also independently building products such as Humble.

Core capabilities

Based on the site copy, Kevin’s key differentiation is his combined background in design, engineering, and founding products. At Instacart, he worked on AI-native WYSIWYG builders for enterprise marketing and development use cases such as emails, receipts, and websites. At Meta, he was responsible for IG and FB Shop International, involving cross-border checkout, multilingual and multi-currency inventory, and compliance. At Ring, he led design for consumer IoT product lines and built the Ring Style Kit design system. The testimonials also repeatedly emphasize his ability to handle complex, ambiguous platform problems and collaborate with cross-functional partners across engineering, product, and content design.

Pricing and engagement

The site only shows “Available for hire,” “Get in touch,” and “Book a call.” It does not publish pricing, project packages, hourly rates, delivery timelines, payment methods, or copyright terms. As a result, it is better viewed as an entry point for senior consulting or project-based design collaboration. The actual scope, licensing, and commercial terms need to be confirmed via a call.

Pros and cons

The main strengths are a solid track record, coverage across AI workflows, B2B enterprise tools, e-commerce, IoT, mobile, and design systems, plus the ability to implement front-end work rather than stopping at visual mockups. The downside is that the case pages are mostly experience summaries, with limited detail on the design process, screenshots, deliverables, or quantified outcomes. For buyers, pricing, availability, post-delivery support, and intellectual property ownership are also unclear.

Who it is for

This is suitable for teams building 0→1 products, AI tools, enterprise SaaS, internal tools, complex editors, IoT products, or design systems—especially companies that want a designer who understands engineering implementation and can help drive execution across teams. It is less suitable for users who simply need low-cost templates, downloadable assets, or a clearly defined subscription-based design tool.

Access from China

The crawled text does not provide information about access from mainland China, ICP filing, CDN setup, or localization, so access should be marked as unknown. For cross-border collaboration, time zones, payment, contracts, and communication tools should also be confirmed separately.
