Questions & Answers

As answered by people managing Revievv and Sing App React Java.

What makes your product unique?

Revievv's answer

Reviewers don't need a CAD license, an account, or any installed software. Just a link. Most design review tools charge per seat or require everyone to have CAD software. Revievv gives unlimited free reviewers on every plan - so your suppliers, clients and cross-functional teammates can give feedback without any barriers.

Why should a person choose your product over its competitors?

Revievv's answer

Some competitors costs six figures and takes months to deploy. Revievv starts at $0, works in 30 seconds, and does what engineering teams actually need: open a CAD file, pin comments on the 3D model, share a link, collect feedback. No procurement process, no IT department required.

How would you describe the primary audience of your product?

Revievv's answer

Mechanical and electrical engineers in teams of 5-50 people — product design, manufacturing, automotive, aerospace. Engineers who send STEP files by email, mark up screenshots in PowerPoint, and lose feedback in chat threads. Also useful for engineering managers who need documented, traceable design reviews instead of meeting notes in Excel.

What's the story behind your product?

Revievv's answer

Built by an engineer with ADHD who got tired of the same broken design review process, also had problems with doing all those related topics — screenshots in PowerPoint, feedback lost in email threads, "see attachment page 3 top left corner." Every CAD collaboration tool was either enterprise-priced or view-only. Revievv fills the gap: real design review with 3D markup, simple enough to start in 30 seconds, affordable enough for a small team.

Which are the primary technologies used for building your product?

Revievv's answer

Three.js for 3D rendering, OpenCascade for STEP/STL geometry processing, Next.js for the web application, and cloud infrastructure for file conversion. Everything runs in the browser — no plugins or desktop installation needed.

Who are some of the biggest customers of your product?

Revievv's answer

Revievv is an early-stage product used by small and mid-size engineering teams. We're focused on onboarding our first 100 customers — teams that need fast, affordable design review without enterprise overhead.
