Rare types of SaaS explained
There are two main SaaS models: vertical and horizontal solutions. Vertical SaaS tools offer tailored functionality to meet the specific needs of particular industries. In contrast, horizontal SaaS solutions provide general-purpose tools that businesses in various sectors can use.
However, the Software as a Service ecosystem goes beyond these two SaaS categories. It has lots of nuanced categories that cater to diverse business scales, niches, and operational needs. Below, we'll explore the core yet still lesser-known types of SaaS.
SMB SaaS (Small and medium business SaaS)
Designed with the peculiarities of small and medium-sized enterprises in mind, SMB SaaS products provide tools for tasks like inventory tracking, staff scheduling, and customer communication. Usually, such systems are cheaper and much easier to operate than others, so they are common in industries such as retail and hospitality.
Micro SaaS
Micro SaaS is a subset of Saas that is small in scale but highly focused on solving very specific problems for niche markets. These tools are often built by small teams or even individuals. They do not require constant reinvestment because they are simple, maintenance-lite projects targeted towards a specific audience. This might include marketing or productivity tools, content-producing solutions, etc.
White-label SaaS
These kinds of products are developed by one firm only to be branded and sold by others. Therefore, it allows businesses to provide their customers software under their own brand name without having to develop it themselves, which can be quite costly. It is cost-effective, customizable to some extent, and ensures faster time-to-market when compared with developing a product from scratch. Hence, they are suitable for use in marketing, hospitality, education, health & wellness, and e-commerce industries.
Open-source SaaS
Through open-source SaaS, enterprises can reach the software’s origin code and consequently adjust it as per their requirements, host it on their own servers, and still enjoy regular SaaS benefits such as updates and support. In education, IT, project management, and other sectors where customization and data control are critical, this method is quite popular.
API-first SaaS
As the name suggests, the core foundation of these SaaS platforms are Application Programming Interfaces (APIs). Such solutions are designed to help businesses connect multiple systems and achieve smooth data exchange and interoperability across different platforms. API-first SaaS allows companies to customize and scale their tech stack with minimal effort. They are especially favored in industries like fintech, logistics, and e-commerce, where automation is key.
Enterprise SaaS
This type of SaaS targets large organizations, such as finance, supply chain, and tech enterprises. Such solutions are customizable, scalable, tailored, and able to address complex operational needs. They often come with a high level of security, strong support, and flexible integration options.
Here's a table that summarizes and compares different types of SaaS:
| Type | Industries | Examples | Key benefits |
|---|---|---|---|
| SMB SaaS | Retail, hospitality, education, logistics | Shopify, QuickBooks, Toast | Affordable, easy to use, scalable |
| Micro-SaaS | Marketing, productivity, social media, analytics | Uptime Robot, Hunter.io, Plausible | Niche-focused, lightweight, low competition |
| White-label SaaS | Marketing, health and wellness, e-commerce, finance, real estate | Vendasta, Yotpo, AppDirect | Custom branding, cost-effective |
| Open-source SaaS | Education, IT, content management, project management | Moodle, WordPress, Redmine | Customizable, community-driven |
| API-first SaaS | FinTech, e-commerce, logistics, healthcare, marketing | Twilio, Stripe, Plaid | Seamless integrations, flexibility, scalability |
| Enterprise SaaS | Finance, tech, supply chain, healthcare, manufacturing, legal | Salesforce, Workday, SAP, Tableau | Robust features, high scalability |
Exploring industry-specific SaaS categories
Industry-specific SaaS solutions, also known as vertical SaaS, are designed to meet the unique needs of specific sectors. Unlike horizontal SaaS that are focused on general business functions across industries, the primary goal of vertical ones is to make niche markets more efficient and innovative.
The key categories addressing the main types of SaaS industries are the following:
FinTech SaaS
FinTech SaaS are created to improve the accessibility, accuracy, and automation capacity of financial services. They help with efficient payment processing, financial planning, and regulatory compliance — for instance, by offering secure payment gateways, real-time analytics, and fraud prevention features. As a result, businesses can make finance management more transparent.
E-commerce SaaS
E-commerce SaaS platforms are mainly designed to help businesses create, manage, and expand their online stores. They often include tools for managing stock levels, marketing, sales analytics and insight reporting, and integrated payment processing tools, amongst others. In addition, such solutions may have user-friendly online store builders together with SEO tools, enabling firms to attract customers while at the same time enhancing operations.
Healthcare SaaS
SaaS solutions in the healthcare industry help revolutionize patient care by improving record management, optimizing remote consultation, and streamlining hospital operations. For instance, clinics and hospitals often use such specialized SaaS for appointment scheduling and secure patient records storage, as well as optimized billing and inventory management processes. Healthcare SaaS platforms focus on data security and compliance with various healthcare-specific regulations such as HIPAA.
Logistics SaaS
Logistics Software as a Service systems are created to help businesses optimize their supply chain operations, inventory management, and route optimization. They offer real-time tracking and predictive analytics features, which help reduce fuel costs, improve delivery times, predict warehouse restocking needs, and more.
Marketing
Marketing and advertising SaaS platforms enable businesses to plan, execute, and analyze campaigns across various channels. By using these tools, marketers can automate repetitive tasks like email marketing, segment audiences for personalized messaging, schedule social media publications, optimize content, and track performance metrics in real time. Ultimately, marketing SaaS provides the flexibility and insights needed to launch effective campaigns and maximize ROI.
| Category | Key features | Key benefits | Examples |

Benefits of SaaS for different industries
Software as a Service products cater to different SaaS industries, helping them offer adaptable, cloud-based solutions that meet a variety of business needs. Although the benefits might differ from one industry to another, the main of them are quite common to most niches.
Cost-efficiency
Adoption of SaaS-based models allows companies to allocate their resources more effectively by eliminating the need to invest in expensive hardware, maintain on-premise infrastructure, or dedicate significant budgets to IT upkeep. Instead, businesses can redirect their time and resources toward strategic initiatives.
Scalability
SaaS solutions are flexible, and their infrastructure can grow along with business demands. Users can easily scale up or down by simply upgrading their subscription plans. This can be especially beneficial for businesses that are just exploring the market and potentially want to scale but do not necessarily have enough budget for that at the moment.
Integration capabilities
SaaS platforms offer quick and easy API and third-party integrations, which allows businesses to instantly connect their favorite tools with minimal effort. As a result, teams can unify their workflows, automate repetitive tasks, and improve operations without the need for extensive development work.
Security enhancements
The average cost of a data breach in 2024 reached $4.88 million — a stunning number. That's why modern businesses go to different lengths to ensure that security is their top priority. And that's why cloud-based SaaS solutions are beneficial. They offer features like data encryption, regular backups, and 24/7 monitoring to make sure that both sensitive business and customer data remain protected.

SaaS development challenges and solutions
The process of SaaS platform development is complex and has its unique challenges. To build solutions that are secure, scalable, and user-friendly, you need to keep these challenges in mind and know how to address them. Below, the Brights team explores common issues and practical solutions that are effective in real-world scenarios.
Security and compliance in cloud environments
SaaS applications often handle a lot of sensitive data, which, in turn, makes them one of the prime targets for cyberattacks. This is especially significant for those types of SaaS products that target industries like finances and healthcare — along with others with high security standards (such as GDPR and HIPAA).
To address these concerns, we recommend:
Leveraging the best SaaS security practices like data encryption, account access protection, multifactor authentication, IAM controls, and data loss prevention techniques;
Working with reliable cloud providers (AWS, AZURE, GCP) that offer built-in tools for encryption, monitoring, and threat detection. For instance, while developing the Termix platform, Brights leveraged AWS to configure a secure cloud environment with strong encryption and real-time monitoring, which helped ensure both data security and regulatory compliance;
Regularly updating and reviewing your security protocols to stay compliant. You can find out more about the best practices in our article with tips on SaaS security.
Scalability under increasing user loads
With the success of a SaaS app, its user number naturally rises. This, in turn, often leads to the increased need to maintain performance, and uptime becomes more demanding. Without ensuring scalability, you risk failing to meet user expectations, which might lead to revenue losses.
To avoid scalability issues in the future, we always suggest:
Breaking down your platform into smaller, independent services that can be individually scaled;
Opting for platforms like AWS that can scale automatically if there's a demand;
Ensuring that database queries are optimized and can grow efficiently.
"When we work with SaaS products built by someone else, we do everything we can to preserve what’s already there. But sometimes, without a solid architectural foundation, there’s just no way around it — reworking becomes inevitable since adding features to a product that isn’t built for scaling takes too long. In the end, building with proper architecture from the start is always simpler, faster, and less costly.”

Brights' SaaS expertise: Case studies
The insights we share in this article come from hands-on experience in SaaS development. To give you a closer look at real-world applications, let’s explore two of our SaaS cases: Showcase and Termix.
Showcase website builder
The idea for Showcase came from a tech entrepreneur and a photographer who understood the challenges faced by creators — censorship, lack of control, and intellectual property risks. So, chosen to be the tech partners, Brights set out to help our client validate the SaaS product hypothesis.
We developed an intuitive website builder that allows creators to assemble landing pages, share photo and video content without restrictions, and monetize it with the help of customizable subscriptions and exclusive content.
Showcase, website builder for digital creators developed by Brights
Since the client’s primary goal was to create a platform that protects content from intellectual property violations, we implemented Unique Digital Watermarking via IMATAG integration. In case the artists’ content gets stolen, they can track it through a detailed dashboard on the admin side of the website.
So, where has this SaaS MVP journey taken us? Showcase attracted its first users even before the official launch, and it hasn’t stopped growing since. With an increasing feature set and plans to expand, the concept proved to be more than successful, and Brights is proud to be supporting every step of its growth.
Termix POS management
For Termix, the Brights team got to develop a scalable system that allows businesses to manage their POS terminals in real-time mode.
We've been collaborating for over three months to revise and restructure the product. UX audit combined with user testing allowed us to improve navigation and data hierarchy for better system monitoring and control. We've also collected modern design elements into a scalable design system, which resulted in a user-friendly application that stands out from competitors.
