## Curator assessment
Reviewed 2026-09-09 by Gabor Kiss against published evidence.

A product studio for funded startups, and the case studies measure the client rather than the work. The Apiax study reports that the fintech went on to raise more than eight million dollars, win startup awards and grow past 75 people across five offices. The Krepling study opens with $4.3 million raised and a five-star review score. Both are real outcomes and neither tells you what Altar built or how it performed.

The AI in the portfolio mostly belongs to the products rather than to the engagements. Apiax turns financial regulation into machine-readable rules served through an API; Krepling is a no-code commerce platform with AI generating design templates. Altar's role in each is product engineering around that idea.

What the library does give you is volume and names: twenty-six case studies, sixteen of them naming the client, across fintech, commerce and marketplaces.

Best for founders who want a product built and taken to a raise, and who will ask separately what the team has trained, evaluated and put into production.

### Key strengths
- Twenty-six published case studies with the client named on sixteen of them, which is unusual volume for a studio of this size
- The startup track record is checkable: Apiax raised more than eight million dollars and grew past 75 people after the engagement
- Consistent focus on regulated fintech and commerce products rather than a scatter of unrelated verticals

### Good to know
- The studies report the client's funding and awards rather than what Altar built or how it performed—ask for the technical scope and the engineering outcome
- Most of the AI belongs to the client's product; ask which models the team trained, evaluated or operated itself
- No rate and no headcount are published—confirm team size and cost before a fixed-scope build
