Dimensions

"Customer Base" is  the total number paying customers or users for Zapier.

Many of these companies do not widely share their user or revenue numbers; hence the possible listing here of "Unknown."

However, if a number appears in this field, that means Left Hook has verified it through a reputable, trusted source, to include SEC filings, podcast interviews, press releases, or other statements by company leaders.

Many of the Opportunities listed on our directory offer multiple ways for a SaaS to offer their functionality to your users.

We classify three different approaches to user experience:

Internal UI: Your users can use some or all of another app's functionality inside your SaaS's app.

Example: Your SaaS offers a small business-focused sales CRM. If they enable this integration, your user can see the status (Paid or Unpaid) of a customer's Quickbooks Online invoice from inside your CRM's UI.

Target App's UI: Your users can access some or all of your app's functionality outside your UI, and inside another app's UI.

Example: Your CRM has an email list for new customers who just paid their first invoice. If they enable this integration, your users can mark an invoice as paid in Quickbooks, and automatically add that customer to the right email list.

Third Party UI: Many of our Integration Opportunities are platforms that require your end user to access a third party tool to build workflows or to map data. Your customer/end user will necessarily have to log into a third system to use it.

Note that some of our Integration Opportunities offer multiple UI options, and this field will reflect this by including any/all UI options available to SaaS partners.

We classify three different hosting environments for any/all code required to power this Integration Opportunity:

Internal: You can host code on your own internal servers; you are responsible for the security of the hosting environment.

Target App: Code is handled by the Integration Opportunity; you must build your app on their platform, and keep your code on their servers.

Custom: You can host your code on a third party server environment like AWS or Heroku. Left Hook often builds and maintains custom code on third-party servers.

Example: Because we build most of our client work in the MERN stack, we often use Heroku or AWS Lamba to host code. Your SaaS may be built on Ruby, PHP, or Microsoft's dotNet; it's unlikely you'll be able to run our custom code on your servers.

These options above are not exclusive, and we've included any/all options that apply to this Integration Opportunity.

To help you gauge the relative difficulty of developing a User Interface to facilitate this Integration Opportunity, we offer these three relative classifications:

Easy

Medium

Challenging

These are mutually exclusive options determined by our development team. Look for helpful explanation in the Notes field below.
