A small company that builds for one job at a time.
Cosmoness started in February 2026 in Greater Noida, UP. The idea was simple: find a job that eats hours every week, and build software that does it properly.
Datum came from watching businesses pay for ads without knowing which ones brought in customers. Clicks looked good in reports, but nobody could connect them to the deals that closed or the calls that came in.
Zymus came from watching training teams lose whole days to certificates: typing names into templates, emailing files one at a time, then answering requests to confirm they were real.
We are a small team. We build each product to do its job well, and we answer our own email.
Do one job and finish it
We would rather ship a product that does its job every day than a long feature list nobody opens.
Your data stays yours
Ad accounts, CRM records and recipient lists belong to you. We use them to do the work and nothing else.
We answer our own email
When you write to Cosmoness, the people who built the product read it and reply.
Plain tools, well tested
We build on well known infrastructure so the products keep running when you are not watching.
Your data stays yours.
You are trusting us with revenue figures, customer lists and the names of everyone you certify. We treat that the way we would want our own data treated.
Encrypted in transit and at rest
Everything you send us travels over an encrypted connection and is stored encrypted. That covers ad data, CRM records and recipient lists alike.
Never used to train AI
Your data runs your reports and sends your certificates. It is not used to train AI models, ours or anyone else's.
Kept under your account only
Your records are stored against your account and kept apart from every other customer. Only the people you invite can see them.
Yours to take back
Disconnect a source whenever you like. Ask us to delete your data and it is deleted. We never sell it.
Say hello.
