About Sedeya
Signatures that hold up here
Signing a contract in Conakry meant printing it, driving it across town, and hoping the scan was legible. Sedeya was built so it does not — an e-signature service designed for Guinean law, Guinean networks and Guinean budgets.
Sedeya is a new product. The team behind it is not. Eleven years of building systems that had to keep running, turned into one product.
What we optimise for
Three constraints, not three features
Three constraints shaped every decision in the product. They are not features we added later.
Built for how contracts work here
French first, evidence you can hand to a lawyer, and an audit trail that records who signed what, when and from where — the questions a Guinean court actually asks.
Works on the connection you have
Signing works on a 3G phone on a bad day. Pages stay light, documents stream rather than download whole, and a dropped connection resumes instead of restarting.
Sovereign by default
Your documents stay yours. Run Sedeya on our infrastructure or host it inside your own, on your own servers, under your own policy — the same software either way.
Where the documents live
Key focus on sovereignty
Documents sit on our managed infrastructure by default, encrypted at rest, with every access recorded in the audit trail. If your policy requires them to stay on your own servers, Sedeya can be self-hosted — the same software, deployed inside your perimeter.
Who builds it
Built by Kalinko Labs
Kalinko Labs is a software company founded in 2015 in Conakry. We build for African constraints — intermittent power, costly bandwidth, and systems that have to keep running for years without a rewrite. Sedeya is what happens when that discipline meets electronic signatures.

How we work
Pragmatic innovation
We ship what solves the problem in front of us, not what demos well. A feature earns its place by removing a step someone does today.
Technical excellence
Signatures are evidence. The cryptography, the audit trail and the storage are built to be examined, not just to work on a good day.
Measurable impact
Days saved per contract, trips avoided, agreements closed. If a change does not move one of those, it is decoration.
Lasting partnership
We stay after the rollout. Migrations, training and the awkward integration questions are part of the work, not an upsell.

Frequently asked questions
Kalinko Labs, a software company founded in 2015 and based in Conakry. It has built systems for institutions, telecoms and public bodies across the region for a decade; Sedeya is its electronic-signature product.
On our managed infrastructure by default, with documents encrypted at rest and access recorded in the audit trail. If your policy requires the data to stay on your own servers, Sedeya can be self-hosted — it is the same software, deployed inside your perimeter.
Guinean law recognises electronic writing and signature as evidence where the signer can be identified and the document's integrity is guaranteed. Sedeya is built around exactly that: identity verification at signing, a sealed document, and a timestamped audit trail you can produce as evidence.
Send us a message describing what you sign and how often. We reply with a short call, set up an account you can test with real documents, and only then talk about a plan.
