Your SaaS is not so SaaSif you develop a solutionfor each customer*

* Trust us, we've been there many times.

Your investors are waiting for your new enterprise customer to start paying. Your product managers are figuring out the colour of the sidebar with the designer. Two engineers are trying to fix the security issue while finance is shocked by the cloud costs this will incur.

Would you like to skip all of that?

A customer request recruits a SaaS companyOne wobbly continuous line moves from left to right, drawing a customer with a brief, a product manager and designer around a screen, an engineer at a coding screen, then finance holding a long receipt.

AI makes building faster. It still takes focus away from your product.

AI can get the first version working quickly. It does not remove the permissions, retries, logs, or customer-specific edge cases that follow. The maintenance bill still grows with every rollout.

When a customer is ready, their rollout should not add another item to the engineering roadmap. Put the workflow layer in Lainstack and keep your product team on the product.

  • Adopt Lainstack
Building an automation engine means maintaining loops, storage, authentication, MCP, errors, retries, and run history. The alternative is to adopt Lainstack.

The Code block receives a carrier event and shipment, calculates the delay, and returns a normalized milestone.

Made by engineers for freight solutions engineers.

Customer integrations are never just credentials and field names. One customer sends clean events. Another buries the same value three objects deep. A third has a spreadsheet that has survived two system migrations.

Lainstack gives solution engineers the blocks to connect the customer and shape the data. If it's really complicated, open Code, read the inputs, write the mapping, and test the output. It stays inside the same workflow instead of disappearing into another service.

Your SaaS already separates customers. Lainstack does too.

In Lainstack, your SaaS is the super organisation. Each customer gets its own organisation and region. Workspaces can follow their teams, products, or operations.

Users, connections, workflows, and data stay with the customer they belong to. Your solution engineers can work across customers without mixing their work or building the boundaries themselves.

Each customer organisation can have its own region and workspaces. Connections, workflows, and data remain scoped to the workspace they belong to.

Give us the docs. We'll build the blocks.

Show us the operations your customers need and the documentation behind them. We can turn the useful actions, fields, and authentication into Lainstack blocks for your product.

Your solution engineers start with named product actions instead of rebuilding HTTP or SOAP requests for each customer. We agree the scope, tests, support, and maintenance before the work starts.

Which customer operation keeps coming back?

Tell us what customers need to do, where the data starts, and where it has to go. We'll work out whether it belongs in a reusable block or the workflow around it.
