As answered by people managing SubmitWell and CodePen.
SubmitWell's answer
Startup founders, SaaS companies, AI tools, and technology businesses launching a new product who want a done-for-you directory submission service without spending hours researching directories, creating accounts, and managing submissions themselves.
SubmitWell's answer
SubmitWell is a manual, done-for-you directory submission service for startups, SaaS products, AI tools, and technology businesses. Every submission is completed by hand — no bots, no bulk automation — across 100+ curated, DR-ranked directories. Each order includes a guaranteed Domain Rating (DR) increase, verified via Ahrefs, plus a full completion report with live submission URLs and screenshots proving the listing is public.
SubmitWell's answer
Most directory submission tools either automate submissions — which gets flagged and rejected by many directories — or hand you a raw list and leave the work to you. SubmitWell does the manual submission work itself and backs it with a guaranteed, verifiable DR outcome and screenshot proof for every directory, so you're paying for a completed, confirmed result rather than a list or a bot run.
SubmitWell's answer
SubmitWell was built around a simple observation: manually submitting a startup to 50-200 directories is tedious and easy to do badly, and most existing services either spam-submit with bots or just sell a list and leave the rest to you. SubmitWell was built to do the manual work properly and prove it — every order ships with a guaranteed DR increase and full evidence of completion. It's grown to 100+ completed orders since launch.
