A Step-by-Step Guide to Software Development for Startups

Startups fight for attention in fast-moving markets. Strong custom software development turns an idea into a product people can actually use. It also helps scale without painful rewrites, while keeping software development costs under control. Demand continues to rise: Clutch’s 2025 report values the global software development services market at approximately $570 billion in 2025 and projects it to surpass $1 trillion by 2030. It also cites forecasts that the custom software development market could grow from around $43 billion in 2024 to $146 billion by 2030.

Working with a custom software development company is already a necessity for many startups, but what about the software itself? Do you already have a product idea or the type of software you want to create? Do you have proper team members or a software development partner that can finalize your project? These and more questions go unanswered for the startup founders. That’s why we created this guide to software development for startups to help you understand the best software development practices and guide you through this huge step toward growth.

Why is There a Need for Speedy Custom Development?

Speed is risky only when it means skipping the basics. In development for startups, speed should mean shorter feedback loops, fewer delays, and faster learning without sacrificing quality.

That matters because market timing drives competitive advantage. The sooner a product reaches users, the sooner it can collect user feedback, validate the idea, and adjust the roadmap. MVP development is usually the fastest way to do that, because it focuses on core features instead of “everything at once.”

Glorium Technologies supports startup software development with a clear software development process built for fast decisions. The development process starts with quick alignment on business objectives, MVP scope, and the right tech stack. Then development teams run sprints using agile methodology, with frequent demos and visible progress. Continuous testing and automated testing help keep releases stable while new features ship.

This approach improves cost efficiency and helps control software development costs. It also reduces rework, supports scalable cloud infrastructure, and gives startups tailored software solutions that can grow without an early rewrite, one of the biggest wins of working with a custom software development company.

When Outsourcing Software Development Makes Sense for a Startup

Outsourcing software development can be a smart move when speed is crucial, but hiring too early introduces additional risk. Many startups begin with an in-house team and then encounter common limitations: slow recruiting, a lack of specialized skills, or insufficient development capacity to meet a tight roadmap.

Glorium Technologies supports development for startups through custom software development services that can complement an in-house team or fully cover delivery. Depending on the stage, this may involve a dedicated team, smaller outsourced development teams for specific workstreams, or full product engineering services, from discovery to launch.

Typical situations where outsourcing is the right call:

• MVP needs to ship fast: A startup can develop software more efficiently by utilizing an experienced software development company that has established repeatable delivery practices. This speeds up idea validation and accelerates learning from user feedback
• The in-house team is incomplete: Startups often lack QA, DevOps, security, or senior architecture. Outsourcing brings those specialized skills without permanent hiring
• Specialized expertise is required for a short window: Mobile, cloud infrastructure, data engineering, integrations, or artificial intelligence (including natural language processing or computer vision) often require deep technical expertise
• Complex integrations are part of the product: Seamless integration with third-party tools, payments, CRMs, or legacy systems is easier with a custom software development company that has experience in this area
• Investor visibility and predictable delivery are needed: Outsourced development teams can help track progress through demos, sprint reporting, and a stable delivery cadence during fundraising
• Focus must stay on customers and business objectives: Product direction, sales, and partnerships often matter more than hiring management early in the startup journey. Outsourcing protects leadership focus
• Capacity must scale up quickly: Traction can require more development teams and faster releases. A software development company can expand or reduce capacity without creating long-term overhead

What strong outsourcing looks like in practice:

• Clear ownership and communication: A project manager keeps scope and delivery visible
• A transparent development process: Regular demos, a maintained backlog, and decisions made fast
• A sensible tech stack: The technology stack fits the product, budget, and hiring plans, using programming languages and tools that support maintainability
• A path to transition back in-house: Documentation and knowledge transfer help build your own team later, if needed
• Ongoing support after launch: Post-launch support, technical support, and maintenance options keep the product stable while new features ship

Outsourcing is not only about cost efficiency. Done well, it delivers tailored software solutions and innovative solutions that help a startup market successfully, and protect quality.

Step-by-Step Startup Software Development Process

The way you conduct the whole development process will impact the quality and likability of your products. We recommend working with a startup development company that uses agile practices and has experience working with companies like yours. In this section of the article, we’ll explore a development process step-by-step.

In simpler terms, the first step is to come up with the idea and draft the concept. You can’t skip this step or rush it since it requires brainstorming, identifying market gaps, and envisioning tailored solutions that address the specific needs of your potential customers. At this stage, you need to have a complete idea of your product.

This stage requires getting to know your audience and stakeholders better. We recommend conducting interviews, surveys, and workshops to capture detailed requirements and offer your audience what they need. You must also define the MVP scope, including key features and advanced functionalities.

At this stage, you’ll be able to see how your product will be presented. Professional UI/UX designers and software architects will collaborate to create an intuitive design and infrastructure for your product prototype. You’ll be able to validate your solutions’ functionality, usability, and flow. This stage sets the foundation for the coding phase and plays a crucial role in delivering a user-centric software product.

Finally, we’ve reached coding. At this stage, your solution takes shape. Project managers use agile development methodologies to break the project into smaller and more manageable tasks or user stories. Software developers start writing code, and QA engineers create testing scenarios to identify and fix bugs. This collaboration delivers the first result.

After successfully passing the testing and quality assurance steps, your product is ready for release. A professional company will advise you on the form and timing of deployment, ensuring a smooth launch.

After successfully passing testing and quality assurance steps, your product is ready to see the light of the day. A professional company with experience in software development for startups will advise you on the form and time of deployment, and it’s ready for a smooth launch.

Don’t forget that deployment is not the last step. Once your product is available, you’ll likely encounter some inefficiencies or face updated industry regulations, market demands, and other challenging environments. That’s why, even post-launch, your product requires continuous improvement and maintenance.

How Startups Can Build a Secure Development Environment From Day One

Startups often treat security as a “later” problem because speed feels more urgent. That works until the first enterprise client, an audit request, or an incident involving sensitive data. The best time to build secure habits is before the product and the team grow.

Glorium Technologies supports startup software development by embedding security into the software development process from the start. The goal is to protect the product without slowing MVP development or blocking iteration. A secure environment also reduces long-term software development costs, because late-stage security rebuilds are expensive.

Key building blocks of a secure development environment:

• Access controls and least privilege: Roles stay clear, permissions stay minimal, and shared accounts are avoided. This reduces risk management overhead and keeps control as development teams scale
• Secure code workflow: Pull requests, code reviews, and protected branches are standard. Automated checks in CI catch issues early and support continuous testing
• Secrets and credential management: Secrets stay out of repositories and local config files. Key storage, rotation, and auditability are set up early to prevent common leaks
• Environment separation: Development, staging, and production remain isolated. Clear release promotion rules improve consistent performance and reduce last-minute deployment surprises
• Dependency hygiene: Modern custom software development relies on third-party libraries. Dependency scanning and patch discipline help avoid vulnerabilities that slip in through packages
• Automated testing for critical paths: Automated testing focuses first on the features like authentication, payments, and permissions. This preserves quality while the product evolves quickly
• Security checks sized to the stage: Lightweight scans and secure coding rules often fit early development for startups. Deeper testing and hardening can be added before larger customers, compliance requirements, or scale
• Secure infrastructure on cloud infrastructure: Logging, monitoring, backups, and environment isolation are set up to support growth and future software compliance needs

Tips for Fast Software Development for Startups

It’s time to explore some of the most interesting and available methods of speeding up software development for startups. We’ve worked with various small, medium, and large companies and have used these methods to speed up time to market while maintaining the quality and functionality of products. Here are our most recommended methods:

Use Agile methodology

Startups work in environments where dynamics shift regularly and demand changes. That’s why it’s essential to use Agile methodologies, which embrace the changes rather than resist them and prepare companies for adopting new markets and shifts. Agile professionals and PMs break projects into bite-sized elements and create more flexibility. This flexibility allows companies to quickly respond to changes while their competitors are still trying to figure out what’s going on.

Prioritize MVP development

One essential tip that we can give to companies for software development for startups is to prioritize working on MVPs rather than jumping into developing the final product. Why? First of all, creating MVP takes much less time than developing a full product. They also give companies flexibility and space to observe how their users interact with their product idea and adjust features and functionalities without major changes to the final product. This approach not only speeds up the time to market but also allows you to deliver the exact product your audience needs without spending extra resources. If you want to work with professionals, we recommend you outsource software development services.

By prioritizing MVP development, startups can minimize the risks associated with building a product that may not resonate with the target audience, enabling them to pivot or iterate early on based on real-world user validation.
It helps to concentrate on the core features, startups can streamline their development efforts and avoid unnecessary complexities. It allows them to release an initial product version sooner, gaining an early foothold in the market and capturing early adopters. The rapid time-to-market provides startups with a competitive advantage and generates valuable user feedback and market insights that can be used to iterate and improve the product.

Outsource development

One of the ways to speed up software development for startups is to outsource the process to a professional company. Outsourcing has been a popular strategy for companies to speed up the process using external expertise. Companies like Slack, Apple, Google, Skype, and Alibaba outsource some parts of their software creation to external sources. This is a cost-effective method of creating final products with the help of a global talent pool.

What does this mean? Such growth signifies that companies are increasingly adopting outsourcing in their workflows as they recognize the numerous benefits and advantages it comes with, including:

• Access to specialized expertise that may be lacking in in-house teams
• Faster time-to-market and increased efficiency
• Opportunity to reduce both development and hiring costs and optimize resources
• Ability to easily scale teams up and down as the situation requires
• Space for the whole team (including stakeholders) to focus on strategic priorities while the external experts work on the product

Create a user-centric design

Did you know that 79% of users will look for alternative solutions and sites if they dislike the design of your product? More importantly, up to 88% of online consumers are less likely to revisit a site after having a negative experience with it. UI/UX is a critical factor that attracts and retains new and existing users and dictates your products’s success. Speedy prototyping and MVP creation can tell you a lot about what design and interactions your users prefer and what frustrates them. Such observations will help you release the final product faster.

Promote continuous improvement

Don’t leave your product after the deployment. Promote continuous improvement, code changes, bug fixes, design changes, and more. Make sure you’re getting regular feedback from your users and QA specialists that you can use to improve and enhance the quality of your solution. This approach helps companies reduce time spent on changes and updates and quickly respond to market demands.

Working With a Startup Software Development Company

Startup owners often have to be the jack-of-all-trades. However, wearing multiple hats to keep your business running smoothly isn’t good for you or your company in the long run, especially if you’re developing a tech product.
