Crowdfunding Platform Programming Languages and Tech Stacks

How can you understand what programming languages were used to develop a crowdfunding platform? 

One of the best ways to find out about crowdfunding platform tech stacks is to check the existing platforms and who they hire. The job description will tell you what a crowdfunding platform developer has to do, what programming language proficiency is needed and what’s the point of developing whatever is required in the job. 

While it may not be a complete picture of all the behind the scenes, it’s still a good and up-to-date indicator of the company’s goals and development curves.

For this research, we used Glassdoor, LinkedIn profiles and information from the companies’ websites. So, let’s have a closer look at some of the top crowdfunding platforms in the industry.


CrowdCube is moving from old-fashioned architecture and creating a platform that is easier to use and is more streamlined and maintainable. The newer pages of the platform are written in TypeScript with React, Redux & Styled Components. The platform is moving older pages to a new architecture whenever it is possible.

At the time of writing the article, CrowdCube was looking for a senior front end developer with knowledge of modern JavaScript frameworks, excellent proficiency in TypeScript & React, and good knowledge of React frameworks such as Redux & NextJS. Understanding of CSS & CSS tooling (pre-processors, CSS-in-JS, etc.) is an advantage, as well as knowledge of RESTful APIs.


StartEngine relies on a rather hyped tech stack. While Python is a popular programming language, it’s an interesting choice to develop a crowdfunding platform. 

From the job requirements, it’s clear that StartEngine is combining the two worlds and uses both Python and Java for development. The company is using Polyglot Programmer principles which say that you need to use a certain programming language depending on the problem you’re solving. Different programming languages can offer different performance and be more suitable to solve a particular problem. 

You can find StartEngine hiring back-end crowdfunding platform developers with experience in microservices, AWS, Kafka, Java, Unix/Linux, and Docker


SeedInvest’s acquisition by Circle has redefined the platform development. Even though SeedInvest is going to continue with the practices they are used to, the platform is going to explore other opportunities beyond traditional assets such as cryptocurrency and blockchain. USDC, a native Circle coin which is also called a “programmable dollar” is going to be used for fundraising purposes. 

Now, the platform is hiring crowdfunding developers who are going to integrate the new technologies to enable users from all over the world to use the opportunities that SeedInvest offers. The new specialists are going to implement a set of solutions to help fundraisers and investors manage funds in a more global, scalable, and efficient manner than the one provided by the traditional banking system. 

Now, the platform is looking for HTML, CSS, and JavaScript developers who know how to work with such libraries and frameworks as Vue, React, and Angular. The specialists are going to work on creating a new infrastructure on providing a seamless onboarding flow, the launch of a DeFi platform, and Identity solutions. 

SeedInvest is also hiring Java and Go developers with experience in Cloud Services such as AWS, Google Cloud, Microsoft Azure, SQL databases and designing schemes, and container orchestration systems such as Kybernetes or EKS, ECS.

SeedInvest claims that they are going to do what they know and like most – help promising startups find their investors. Judging from the open positions and their description, we are expecting the development of a new DeFi platform with USDC as the main currency used for investment purposes. 


CrowdStreet uses React JS as the main programming language to enhance its functionality and improve the user interface. As for the back-end, CrowdStreet is using Java. 

To organize their development and project management work, the Atlassian ecosystem is used including tools like JIRA and Bitbucket. 

As for the hosting of the platform, CrowdSteet is using Amazon Web Services because it provides decent security and arguably highest flexibility when it comes to the use of resources and configuring environments for development. 

For their project management, they use the Agile/Scrum methodology which is one of the most popular in the IT world. 


EquityMultiple uses TypeScript and React to build, extend, and maintain the platform. It’s also using WordPress which is a content management system for websites. 

At the time of writing, the company didn’t have open positions, so we had to study LinkedIn profiles which may give not very precise data about the programming languages and development goals.

Mintos is continuously shipping out new features and updates in the marketplaces, so the platform is hiring investment platform developers who can contribute to the creation of complementary client-side marketplace solutions, including creating new and improving existing web components and enhancing the platform’s infrastructure and user interface.

For this, the crowdfunding platform developers need to have knowledge of JavaScript/TypeScript and modern web development practices, experience with client-side frameworks and libraries such as Vue, React, or/and Angular is a benefit. 

The platform is expanding its compliant payment services. To build something related to payment processing, Mintos is looking for Java developers.

The P2P lending platform developers will be responsible for managing the software development cycle, building Java microservices, and writing automated tests.

The company outlined this tech stack: 

  • Java 17, Spring Boot 2.6.x;
  • Groovy 3, Spock 2.3;
  • Lombok, vavr;
  • Cucumber for end-to-end tests;
  • RabbitMQ for inter-service communication;
  • WebFlux for HTTP APIs;
  • Liquibase, PostgreSQL, Redis as the persistence layer;
  • Gradle, Docker, Kubernetes;
  • GitHub for source control;
  • AWS services (EKS, ECR, CodeBuild, CodePipeline, RDS, CloudWatch).

Hire a crowdfunding developer or use crowdfunding software

To develop a crowdfunding platform, one needs to choose from a wide variety of programming languages and other tools to perform and monitor marketing activities, ensure the platform’s availability, enable smooth and secure payment processing ways.

Maintaining and enhancing the functionality of an existing platform is challenging. Developing a platform from scratch is even more complicated. 

One of the best ways to go about launching and maintaining an online crowdfunding platform might be getting a ready-made white-label crowdfunding software with a team behind it who can build and customize everything to your needs.

Consider using white-label crowdfunding solutions from LenderKit to launch your investment platform with fewer expenses and ensure that it has all the functionality to operate.
