Effortlessly streamline client onboarding, identity checks, and background screening within your existing software.

Integrated Identity Checks 1

Why StackGo?

Businesses hate buying new software that doesn't integrate with their existing tech. This is particularly painful when it comes to mandatory tasks like Identity Verification, customer onboarding, or other screening and compliance workflows. The process must be completed, yet robust enough to minimise mistakes.

What most businesses do is design manual processes, which are tedious, inefficient, prone to human error, and require additional oversight. Other software solutions are not designed to be integrated out the box. They may have a loose 1-directional push integration, or use Zapier-type solutions that are unreliable, incomplete, and prone to going wrong. Businesses tell us they are fed up with having to learn new software, having extra tabs open, or endlessly designing and building new customised automations.

At StackGo we believe software should be designed to integrate out the box with your existing tech stack. You can operate our software from your existing technology that you're already comfortable with. There is nothing new to learn, no extra tabs open, and the data and workflows work seamlessly out the box. Our clients tell us they love the simplicity the most - it just works!

Frequently Asked Questions

We have built a small number of our own apps to demonstrate the capability of our platform. Our platform has enabled us to build multiple solutions with minimal resource, and hopefully this provides you inspiration for what’s possible with your own products.

Sometimes. App Marketplaces are a rapidly evolving concept. Major platforms like HubSpot, SalesForce, Xero, Atlassian, and Shopify have maturing App marketplaces and some co-selling / co-marketing support. This is not always the case though. Our strategic advice is first to integrate with the platforms your customers are already asking about, in a way that can be generalised onto alike platforms. You can then offer these integrations as product features, and a way to onboard new customers faster. As you begin to get traction, you can then seek a marketplace listing and seek additional support from the SaaS platforms. All StackGo customers receive further strategic advice on this approach, currently at no additional charge.

Productized integrations have been built with 1:many customers in mind. The feature set has been designed around generalised use cases. This means customers can start faster, costs are lower, and you can scale faster.

Absolutely! We encourage you to just use the underlying power of the StackGo platform, and build your own products. All customers get free support, and if you need additional help to bring your product to life, we can provide affordable access to the expertise you need.

Zapier puts the onus on the customer to build and manage their own integrations to your software. This can slow down onboarding, and turns many customers off. Zapier is also highly restrictive as you do not get native access to the API – it’s good for only very simple use cases. We recommend thinking about productizing your integrations via StackGo – your customers can self onboard super fast. They will love the simplicity, and stick around for longer. You are also investing in long-term difference from your competition who rely on Zapier alone.

Absolutely! We love API businesses. Talk to us about the best way to proceed. You can use our App Container to build your own integrated product super fast. We can provide you a quote, or work out some other partnershsip. Enter your email to get started, and we can talk.
