Build it once. Deliver it to every client
Every client engagement starts by rebuilding the same plumbing: login, permissions, logging, storage. It eats your margin and no client pays to see it. Sinas gives each client an isolated instance with all of that already in place, so your team bills for the thinking instead of the auth layer. Sinas is an initiative of WeAreBrain, and this is how we use it ourselves.
Sound familiar?
If you deliver AI work for clients, you have probably said at least one of these. Here is what changes when you build on Sinas.
Faster time to value for every client
Every AI engagement quietly includes the same infrastructure work, and none of it is what the client pays to see. Sinas ships it with the platform, so your first client sees results sooner, and whatever you build can be installed for the next one in minutes.
From day one: what you no longer build
Access and trust
Authentication and API keys
Password or email code, scoped keys, JWT refresh. Built in, on day one.
Permissions
Role-based access on every call, so each client team sees only their own data.
Execution logging
Every agent call, function run and query, tracked with timing and errors.
Data and memory
Connected to client data
Connectors and reviewed queries into each client’s own databases and tools.
State and memory
Namespaced key-value storage, so conversations survive between sessions.
File handling
Upload, version, validate and search, without wiring up storage.
Running the work
Scheduling and webhooks
Cron and inbound HTTP, without another service to operate.
Running at scale
Queues, retries and large batches, so busy moments never drop work.
Safe code execution
Python functions run in a locked-down container, away from client systems.
On every next client: build it once, deploy it again
Deploy it again
Upload it to the next client instance and adjust the parts that differ.
Keep it private
A package is a file you hold, not a listing you publish. Your library stays yours unless you choose to share it.
One instance per client
A tier carries several instances, and each client gets their own. That maps cleanly onto how agencies work, and it makes the platform a small, predictable line on each engagement rather than a build cost.
How it usually runs
One instance per client, so data, keys and permissions never mix
Several applications on that one instance: support agent, internal tool, workflow
Starter (€49/mo) includes 3 instances, Professional (€199/mo, coming soon) includes 8
Bill it through as a pass-through cost, or fold it into the retainer
Partner terms
Running several clients?
If you are deploying instances for a portfolio of clients, talk to us before you buy them one at a time. We would rather set up terms that fit how you deliver: consolidated billing, volume arrangements, and a single point of contact for support across all of them.
Ready for your client’s security, legal and procurement
The three reviews every engagement goes through, answered in one place. Send it to them, and anything it does not answer we will answer in writing.
