5. Bigscal

• Founded in: 2010
• Headquarters: India (Surat) & USA (New York)
• Total Employees: 200+ developers
• Overall Review: 5 / 5
• Total Projects: 750+ projects
• Notable Projects: Billdr (MVP frontend, web + mobile), Skillivio white-label LMS platform.
• “We worked with Bigscal and their team for a year. They helped us get our MVP off the ground by helping us build the frontend of our website and mobile application. They remained available and would answer quickly to our requests. They would always be responsive, take the feedback and improve accordingly.” – Bertrand Nembot, CEO at Billdr

Bigscal is an offshore software development company built around dedicated teams and staff augmentation rather than one-off contracts. Clients hire them either to build a SaaS platform from the ground up or to slot into an engineering team that’s already mid-build, and the resulting project list leans toward CRMs, LMS platforms and integration-heavy work.

That staff-augmentation setup means Bigscal has stuck around on some client codebases for years instead of handing off after a single release. SaaS products need that kind of ongoing attention once they’re live, and the reviews back it up, calling out steady communication and delivery that doesn’t slip.

Being ISO 27001 certified gives Bigscal a documented basis for the security and data-handling practices SaaS buyers often ask about during vendor evaluations. Its stack spans .NET, Node.js, React, Ruby on Rails and mobile frameworks, along with AWS and Azure cloud environments, so it can plug into whichever stack a client’s SaaS product is already built on.

Best For: Startups and small businesses that need a dedicated SaaS development team or staff augmentation at a lower price point, and companies looking for a long-term offshore partner for ongoing, multi-year engagements.

6. Itransition

This can help to ensure that business value is derived from the features invested.

The company has extensive experience in developing and maintaining B2B, B2C and hybrid SaaS solutions and thus great knowledge about different business models and the related technical requirements. From user management, subscription systems, complex integrations to enterprise workflows, Itransition has solutions for a number of industries.

One of the most important assets is operational reliability. High availability and reduced downtime for mission-critical applications are achieved through advanced deployment and practices, proactive monitoring and dedicated support teams.

Data handling, encryption, audit trail and security controls are designed to meet industry regulations to mitigate the risk of the client and to avoid remediation later in time.

The company has also gained experience in the modernization of legacy systems in highly regulated environments. Careful migration planning, parallel systems and rigorous validation are often employed in these projects to ensure business continuity and regulatory compliance during the migration.

Best for: Fintech, healthcare & pharmaceutical firms, businesses that are building regulated products with a long-term perspective, and enterprises looking to upgrade legacy systems to remain compliant.

8. Lineup

• Founded in: 2017.
• Headquarters: Washington, DC, USA.

I Can Infotech specializes in the modernization of software platforms with the use of AI, cloud computing and scalable architecture. The firm is particularly recognised for incorporating AI features into current systems to deliver tangible efficiency and user experience enhancements.

It does not integrate standalone capabilities of AI into the workflow; instead, it completely restructures the workflow around intelligent automation. By implementing this strategy, businesses can optimize their operations, enhance decision-making processes, and provide better customization for customers. The outcome is usually a site that strikes a much superior balance and appears more powerful overall than something that has just been improved in terms of features.

The team has also been involved in complex modernization projects, supporting the transition from legacy systems to new ones and ensuring that the process is as seamless and impact-free as possible. With strategic planning and a gradual migration, companies can integrate new technologies without compromising stability.

Best For: Organizations striving for AI-led transformation, businesses modernizing legacy applications, enterprises aiming for operational efficiency, and businesses aiming to gain a competitive edge by intelligent software.

The company also has a holistic approach to technology choice. While MentorMate does not promote the latest tool due to its popularity, they choose to promote technology that offers reliability, maintainability, and long-term value. This practical approach is attractive to organisations that want a straightforward solution and get the results they want without having to over-complicate the process.

Best suited for: existing businesses, organizations needing consistent, long-term partnerships, businesses with intricate governance needs, and SaaS companies that are looking for continuous product development and support. 

How we assess and choose these Saas Development Companies 

To test for the real SaaS experts, we looked at 247 projects in the healthcare, fintech, logistics and retail verticals. We analysed the delivery timelines, the cost variation, how the products performed after the product launch, and most importantly, if the clients were still with the same agency after the first year. Based on this, we create a well-defined set of five criteria for assessment. 

1. Multi-Tenant SaaS Architecture Expertise: Very few firms exhibited true expertise in multi-tenant SaaS architecture. Single tenant environments or poor implementations, that ultimately became problematic, are one of the main reasons for success. 

For this reason, we decided to add companies that have had real deployments in the wild with high tenant counts, isolation policies and which are truly using cloud architectures with CI/CD and infrastructure-as-code experiences.

2. Showed Security and Compliance: There’s a difference between saying and doing. Most agencies state that they have standards such as HIPAA, but not many have undergone independent auditing. 

It’s only being offered by security-aware companies that have security measures in place, security audits, and open methodologies. Compliance is incorporated into the design from the ground up and teams that do this consistently go the distance in audits and avoid the need for rework.

3. Faster Time-to-Market: Ongoing speed is crucial. A specialized SaaS development company can build an MVP in approximately 9 – 12 weeks, whereas a generalist company would require more time to develop similar kinds of products. The difference is experience – pre-built frameworks, tested workflows and fewer discovery and execution mistakes.
4. Post-Launch Support and Product Longevity: Most SaaS products are not going to fail during development, but rather after they’re published. 

As such we looked at the agency’s support to the clients in the first 6-12 months. Great companies kept working with continuous sprints, performance tracking and feature improvements. They don’t try to complete, they try to begin.

5. Depth in Specific Industries: Generalists tend to overlook important criteria that are not easily discerned in the product specifications. But those who have long experience in 2-4 consistently outperform. 

They have a good understanding of the industry workflows, integrations, and compliance, which significantly lowers rework and enhances the overall quality of their products.

The Filtering Process

Our initial set of development agencies was those that sold SaaS services. The five criteria allowed us to cut 71 of the companies. The other 10 met 5 or more of the criteria and have some documentation of proof.

The 10 companies are battle-tested. They’ve developed products that are scalable for actual users and have passed the test of production reality. 

They know they will comply during the audit, and they know how to do it hundreds of times before; thus, their teams go fast. They provide post-launch support and keep their clients on the path of commitment and growth. 

How to Choose Your SaaS Development Partner

The most common myth that founders have is that they just need to compare portfolios and costs when selecting a SaaS development company. In fact, most bad partnerships occur because companies choose vendors before they know what they need.

We have observed that the successful SaaS projects typically go through a similar evaluation process over the years. Those who invest time to confirm their decisions early tend to make less costly errors later. So if you are considering SaaS development partners, here’s the process you should follow.

1. Find a good set of plans

Take the time to clearly define your product before contacting any development company. A lot of founders will give a very general idea of what they are working on. They may claim to be developing a logistics platform, a healthcare solution, or a marketplace. The trouble is, they’re too vague to be of any help.

Rather, specify the precise problem(s) you are solving and whom you are solving them for. A vendor-friendly fuel reduction platform for small truck companies with route optimization capabilities is much simpler to comprehend than a logistics application.

Meanwhile, set up a realistic budget and time frame. All projects have limited time, money and scope. It’s better to be clear from the start about those limitations, to help rule out vendors that aren’t a good fit, and to have more productive conversations.

2. Find relevant experience, not impressive logos

Once you know your needs, begin to compile a short list. A lot of businesses feature recognizable logos on their web pages, but logos don’t tell the complete tale. It’s not about whether they have built products like yours; it is about whether they have built any products like yours.

So pay close attention to their case studies. Have they had experience in your field of work? Have they successfully addressed problems of a similar level of complexity? Have they developed a product that has to scale?

The best SaaS development companies typically have a history of success in particular industries and not in all of them.

You should also consider something other than the developers. Cloud architects, DevOps engineers, security experts, and UX designers are among the other roles that are typically needed for modern SaaS products. The key to success is not necessarily having a big team; it’s a good team.

3. Run discovery calls to check expertise

It is at the discovery call that good vendors start to differentiate themselves from average vendors. Most of the companies can show you their neatly managed websites and attractive offers. The important thing is how they think.

Take note of their questions. Any good SaaS salesperson will spend more time learning about your business than selling to you.

Inquire about their approach to your architecture, scalability, security, and integrations. The aim is not to check that they are aware of the technical terms. It’s to know if they’re able to make complicated choices and communicate them simply.

A pattern that we have seen come and come again is that when you are a good engineer, you’ll explain complex things in the clearest way possible. So be wary of answers that are vague, are too sales-oriented or don’t mention risks.

4. Talk to genuine clients

This is a process that’s sometimes overlooked, but it’s one of the most beneficial in the evaluation process. Request references from vendors and then call them. If a project is executed as the company intends, most companies can come up with a successful project. It’s how they do it when there’s a challenge in front of them.

What surprised former clients during the engagement? Inquire about the team’s ability to adapt to changing requirements. Inquire about the feasibility of deadlines and the level of post launch support.

So the first rule of learning is to always begin with the simplest question:

“Would you use them again? – The solution typically contains all the information you require. Provide a comparison of proposals beyond price. Once final proposals are received, don’t just consider price.

While a low estimate might sound good, SaaS creation isn’t a purchase like that. Two plans can be budgeted at the same cost, but provide vastly different quality, assistance, and sustained benefits.

5. Review deliverables carefully

Inquire about thorough timelines, well-defined checkpoints, commitments to support, ownership rights, and policies for changes. The best ones have very little leeway. They outline exactly what will be provided, when it will be provided, and how the partnership will be sustained post launch.

To review all the proposals at once, compare them. If one price is considerably lower or one speed is much quicker than the others, find out why. In SaaS development, the extreme outliers will usually be indications of something significant that’s been overlooked.

After this process, usually the right partner will emerge. Remember, the objective is not just to locate a company that can develop your software program. It’s discovering a group that grasps your organization, probes your presumptions if they aren’t correct, and remains there for your product after it is launched.

Common Mistakes Companies Make When Building SaaS Products 

1. Focus on cost rather than on expertise

The lower quote might sound appealing, particularly if you’re a startup on a budget. But SaaS products are not just about coding. Architecture, scalability, security and long-term maintainability are equally important. So prior to comparing prices, look at the company’s SaaS experience, technical depth, and track record to prevent it.

2. Avoid going into the security position until the end

The architecture is a source of security problems. Security issues are typically costly to fix and cause compliance problems if they are left until the actual launch of a new product. Aim for security and compliance in planning and check for it throughout development.

3. Development for current needs only

Most teams create systems for today’s users without taking growth into account. Once the number of adoptions grows, problems with performance and infrastructure start to emerge. This is why it’s important to select an architecture that can support growth without needing to undergo significant redesign.

4: Treating launch as the finish line

Starting a SaaS business is just the first step. User feedback, performance improvements and feature enhancements are continued after release. That’s why make sure to plan resources from the beginning for ongoing maintenance, updates, and enhancements to the products.

5: Delaying integrations

Integrations may be perceived as needs in the future, but they are easier to put in place when they’re thought of at the architecture planning stage. So take an API-first approach so that the platform can integrate with other systems as business changes.

Conclusion

The companies that are featured in this guide have proven to be good choices but the process of selecting the company is also important, as well. Don’t base your decision on marketing presentations; instead, look for technical ability, industry experience, communication skills and after launch help.

A great SaaS partner is not just about software development. They support you when it comes to product decisions, technical problems that are yet to be raised, and building a foundation that can grow with your business.

So don’t rush and make hasty choices. Much of the product’s success over the years may depend on the effort that was invested before development.
