Apply for founding access
The founding cohort is a small group of working appraisers — the first 10 to 20 approved signing appraisers. Applications are read by a person. Approval sends you an invitation; it is not granted here.
Start with a 30-day founding evaluation. No card is required to begin. Founding Pro is $99/month after the evaluation. Founding Intelligence is $149/month after the evaluation and includes 500 pooled Aria credits per account each month. Plans are monthly, cancel anytime, and the founding rate is protected for the first 12 paid months.
AppraisalOS is in a controlled founding cohort. It provides UAD 3.6 authoring and internal PDF/XML/package checks for supported closed-beta scenarios. AppraisalOS is not currently listed as a GSE-verified UAD 3.6 appraisal software provider. Official Compliance Rules API results, UCDP submission, lender acceptance, and GSE acceptance remain external.
