Ridgechart is a marketplace for expert review. Post a paper with a fixed review fee, and verified domain experts get paid to check whether the methods hold up, the results are correct, and the ideas are new.
The problem
With a laptop and a subscription, almost anyone can generate a paper that looks credible, even in a field they’ve never studied. It’s already happening in astrophysics. But judging whether work is actually sound still takes years of expertise, and that hasn’t changed.
Any topic, any field, from anyone with a laptop and a subscription.
A small pool of people can do it, and that is the scarce resource.
How it works
Think Upwork, but for peer review. Ridgechart connects a growing flood of research with the small pool of people qualified to judge it. Submitters pay for the review, and that money pays the experts who do it.
Anyone can post a paper or preprint: independent researchers, labs, startups, or people who used AI to get there. You pay a fixed review fee up front.
Your paper is listed for reviewers whose expertise in that field has been verified. They choose which papers to take on.
Experts check the methods, results, and novelty, and write a structured assessment. They get paid when they deliver it.
You receive the full review: what holds up, what doesn’t, and why. It’s a trusted signal of quality that you can share.
Is the design sound, are the assumptions stated, and could someone reproduce it?
Do the data, derivations, and analysis support what the paper claims?
Does it add something to the field, or does it restate work that already exists?
Both sides of the marketplace
Who pays whom
The money flows one way. The person who wants their work checked pays for the check, and the experts who do the checking are the ones paid.
Up front, when the paper is submitted. The price is known in advance.
Matches the paper to verified experts and keeps the fee until the review is delivered.
The same amount whether the verdict is positive or negative.
You’re paying for an honest assessment, not a good one.
Integrity
Submitters pay the same fee no matter how their paper fares, and nothing they pay can change what the reviewer concludes.
Reviewers are paid the same whether they accept or reject. Being generous earns them nothing, and neither does being harsh. The only thing left to do is get it right.
Every reviewer builds a public track record based on how well their assessments hold up over time, as results are replicated, cited, or retracted.
Reviewers are vetted for real domain expertise before they can take on papers in a field.
The submitter. You pay a fixed fee when you submit a paper, and that fee is what pays the reviewers. Reviewers never pay anything.
No. You’re paying for an expert’s honest judgment. Reviewers get the same fee whatever their verdict, so they have no reason to go easy on you, or to be harsh.
When they deliver a completed review. Ridgechart holds the submitter’s fee until then.
Three questions: do the methods hold up, are the results correct, and is the idea new? You get a written assessment that addresses each one.
Anyone. Independent researchers, students, labs, companies, and people who produced their work with AI tools are all welcome.
Only experts whose domain expertise we’ve verified, and only for papers in their field.
Each reviewer has a public track record. Over time, as work is replicated, cited, or retracted, it shows whether their assessments held up.
No. Ridgechart is a marketplace for expert review. We don’t publish papers; we connect them with experts who check them, and you can share the review wherever your work appears.
