How an Engineering Review Works
From submission to delivered report in about two weeks. AI does the legwork. A real engineer delivers the opinion.
Start in Your Free Workspace
Before any of the steps below, you can create a free account and use Invention Space as your workspace — capture and track your ideas, organize your notes and research, and store sketches and documents. Shape your concept for as long as you like at no cost. When you're ready for an expert opinion, the paid review picks up from here.
- Track unlimited ideas — free, no credit card required
- Organize notes and research across every project
- Upload sketches, patents, and product photos
Submit & Pick a Tier
Fill out a short form describing your invention — what it is, what stage you're at, and the questions you most want answered. Pick a tier and pay. Most submissions take 10 minutes or less.
- Three tier options: $199, $699, or custom-scoped
- Optional: attach existing sketches, CAD, or prototype photos
- Confidential by default; NDA available for Engineering Engagements
We Prep With AI
Once payment lands, our AI runs a full technical and market scan on your idea — feasibility, competitive landscape, IP, prior art. The engineer assigned to your review reads the output first so the call isn't spent on Wikipedia-level basics.
- AI scans across 8 evaluation dimensions
- Real web research, real competitor profiles
- Engineer reviews and pushes back where the AI is wrong
Talk to a Real Engineer
A 30 or 60 minute video call with a design engineer who has shipped physical products. Bring whatever you want to dig into — manufacturability, market positioning, IP risk, technical alternatives. You can argue with us. That's the point.
- Scheduled within 1 business day of payment
- Most calls happen 3-5 days after booking
- Recording available on request
Get a Written Deliverable
Within 5 business days of the call, a written summary or full report lands in your inbox. What we think is strong, what is risky, what we'd change, and what realistic next steps look like. Yours to keep, reference, and share with co-founders, attorneys, or investors.
- Feasibility: written summary of findings
- Full Assessment: detailed multi-page report with recommendations
- Engineering Engagement: ongoing deliverables (CAD, prototypes, vendor lists)

How We Think About This
Two principles that shape every review.
Engineers, not analysts
The person reviewing your idea has built things. CAD, prototypes, manufacturing handoffs — not just spreadsheets and slide decks.
AI as prep, not product
We use AI to do the legwork so the engineer's time is spent on judgment. Your money buys engineering opinion, not a chatbot's hallucination.
What a Review Covers
Every Feasibility Review and Full Assessment touches these areas, scaled to the tier.
