About Zelrin

Zelrin is a marketing-performance product built by Zelrin Corp LLP in Kota, Rajasthan. It reads a business's ad accounts and website, finds where money is being lost, explains why in plain language, and recommends the specific fix — and it does not change anything without being told to.

Why it exists

Most small businesses that advertise are spending money they cannot see the shape of. The reports they get are either a spreadsheet nobody reads or an agency summary that grades its own homework. The questions that actually matter — which part of this budget is doing nothing, and what should I do on Monday? — usually go unanswered, because answering them honestly sometimes means saying "this campaign we manage is the problem".

Zelrin is built to answer those two questions with evidence attached, for a business that does not have a full-time marketing team and cannot afford to take the answer on faith.

The rules the product holds itself to

These are enforced in the code, not just stated here.

We test this on ourselves

Zelrin's own scanner is run against zelrin.com. It has found real problems on this website and, twice, found bugs in itself — a check that called a normal signup flow a dead end, and a readability score that graded a pricing table as if it were prose. Both were fixed. A tool that only ever finds fault with other people's sites is not being run honestly.

Who it is for

It is not an agency, and it is not a bid-management tool. It does not take over your accounts.

Zelrin is operated by Zelrin Corp LLP, registered in India.
