What our AI judge actually said
Anonymized critique from real Developer Tools applications (shared with founder consent).
“Zero paying customers and no usage metrics after 6 months means you are racing Unity's AI features with no proof anyone will switch.”
6.9/10·Sharp team, real product, but traction is pure hope. Show 10 developers using it weekly or this is a feature, not a company.
“Zero traction evidence, no working prototype, no users, no revenue, just a pitch deck with unproven $50/mo pricing assumptions.”
3.9/10·Strong market and real pain point, but you give me almost no evidence that you can actually execute or ship.
“You matched Sonnet 4.6 on $3k but have zero revenue, no LOIs, no pilots, interest is not customers.”
7.3/10·Strong technical founder with real domain edge, but solo execution risk and no commercial proof yet.
“This is not an application, it is a form template with a name and tagline typed in.”
0.0/10·Cannot evaluate an application that does not exist. Fill out the form, then reapply.
“Three free pilots with no revenue and vague pricing is not a business, it's a feature waiting to be absorbed by Komodor.”
6.6/10·Strong technical team hunting for product-market fit in a crowded space. Prove one pilot converts to paid, or this stays a science project.
“The biggest risk is whether intent intelligence becomes a durable category or just a feature waiting to be absorbed by Mixpanel and Amplitude.”
7.9/10·Strong team moving fast in a huge market, but retention and expansion signals will determine if this is venture scale or feature-sized.
