Emailmetry keeps your SPF record working as your business adds email services. Every service that sends email for your domain, such as your mailbox provider, accounting software, CRM or newsletter tool, adds lookups to your SPF record. SPF allows 10. Go over that limit and the invoices, password resets and order confirmations you send can fail SPF and be rejected or sent to spam, often without anyone being told. Emailmetry flattens supported SPF records into their sending IP ranges to bring th
AppealHound is AI denial-appeal software for US medical billing companies, RCM firms and the specialty practices they bill for.

Embeds can be restricted to your own domains and c
Most idea validators are feel-good machines: paste an idea, get a "promising" score, build for months on a vibe. WhittleOS is the opposite — deliberately kill-biased. It sources real candidates itself, links the problems it cites to the page each was read on or labels them as its own estimate, computes the 0–100 score in code from a fixed weighted rubric rather than asking a model for a number, and honestly hands back nothing when a market is weak. Built for solo and indie founders who want a
