The success of startups often relies not only on the originality of the idea but also on the team's ability to swiftly adapt to changes, make efficient use of limited resources, and bring innovative solutions to the market. However, when choosing technologies, early-stage founders frequently encounter a variety of challenges. According to a CB Insights study, around 38% of startups fail due to a lack of funding, with technical errors and poorly chosen tools directly contributing to increased costs for product support and development. According to a CB Insights study, For example, in 2016, the startup Zenefits lost millions of dollars due to errors related to their technology stack, including the use of outdated tools and insufficient system scalability. This slowed down the company's growth and undermined investor confidence. in 2016, the startup Zenefits lost millions of dollars due to errors To minimise these risks, more and more startups are opting for a lean tech stack—an optimised technology stack that allows them to build products with minimal costs while maintaining quality and flexibility. This approach helps to: This approach helps to: Launch an MVP (minimum viable product) faster and receive initial feedback from users. Attract early customers and investors by focusing on creating value rather than managing complex infrastructure. Support business growth without costly migrations to new platforms.

For example, the startup Buffer, which started with a simple tech stack, was able to quickly test its idea, attract its first users, and then scale gradually by adding new tools as needed.

This knowledge will help you understand how to choose the optimal technology stack to accelerate development, reduce risks, and lay the foundation for long-term success. What is a Lean Tech Stack and how is it used? A Lean Tech Stack is a minimalist approach to selecting and using technologies aimed at optimising the development and maintenance of digital products. The main idea is to minimise redundancy and focus on the efficient use of resources — time, money, and human effort. This approach is especially beneficial for startups, which need to quickly enter the market and adapt to changing conditions. 4 key principles of Lean Tech Stack Minimalism Using only the technologies and tools that directly contribute to achieving goals. "Heavy" solutions that require significant investment and complex implementation are excluded. Flexibility Choosing technologies that are easy to scale or replace, depending on the business needs. Speed of Implementation Preferring tools with simple integration and training, allowing the team to start working more quickly.

Research: Analysis of technology costs in startups Data on the distribution of startup budgets for technology According to research conducted by Startup Genome and CB Insights, startups spend an average of 25-35% of their budget on technology and IT infrastructure. Approximate distribution of startup budgets on technology: Category Share of the IT budget (%) Cloud services and infrastructure (AWS, GCP, Azure) 30-40% Development and testing 20-25% Licenses and SaaS tools 15-20% Cybersecurity 10-15% Analytics and monitoring 5-10% Other expenses 5-10% Category Share of the IT budget (%) Cloud services and infrastructure (AWS, GCP, Azure) 30-40% Development and testing 20-25% Licenses and SaaS tools 15-20% Cybersecurity 10-15% Analytics and monitoring 5-10% Other expenses 5-10% Category Share of the IT budget (%) Category Category Share of the IT budget (%) Share of the IT budget (%) Cloud services and infrastructure (AWS, GCP, Azure) 30-40% Cloud services and infrastructure (AWS, GCP, Azure) Cloud services and infrastructure (AWS, GCP, Azure) 30-40% 30-40% Development and testing 20-25% Development and testing Development and testing 20-25% 20-25% Licenses and SaaS tools 15-20% Licenses and SaaS tools Licenses and SaaS tools 15-20% 15-20% Cybersecurity 10-15% Cybersecurity Cybersecurity 10-15% 10-15% Analytics and monitoring 5-10% Analytics and monitoring Analytics and monitoring 5-10% 5-10% Other expenses 5-10% Other expenses Other expenses 5-10% 5-10% Common mistakes of early-stage startups Tool redundancy At the launch stage, startups often opt for more complex solutions than necessary. For example, they may choose expensive CRM systems instead of free alternatives. An example of this mistake: Choosing SalesForce for customer management when a free plan from HubSpot would be sufficient. Overpaying for licenses Many startups pay for premium features that go unused. An example of this mistake: Purchasing DevOps, tools that duplicate the capabilities of cloud providers (for example, Terraform and AWS CloudFormation). Underestimating the costs of scaling Using tools that can't handle traffic growth and require a complete replacement at later stages.

Survey and research results Popular tools among startups: Key findings from the surveys: About 60% of startups begin with the free plans of popular SaaS tools. This helps minimise costs in the early stages, when budgets are tight. 70% of startup founders admitted that up to 20% of their budget was spent on unnecessary tools. Approximately 50% of startups opt for open-source technologies to reduce costs. About 60% of startups begin with the free plans of popular SaaS tools.

How to choose tools for a Lean Tech Stack? Step 1: Defining the startup's needs Before choosing tools, it’s important to have a clear understanding of the business needs, which can vary depending on the stage of development. 1.1 MVP Stage (Minimum Viable Product) At this stage, a startup needs to focus on quickly launching the product with a minimal set of features. The main goal is to test hypotheses and gather user feedback. Main tasks: UI Development. Database Setup. Web Server Deployment. UI Development. Database Setup. Web Server Deployment. Recommended tools: Frontend: React — a library for building user interfaces. Backend: Node.js — a server-side platform for rapid development. Data Storage: MongoDB — NoSQL database, ideal for dynamic data. Testing: Jest — a tool for testing JavaScript applications. Frontend: React — a library for building user interfaces. React Backend: Node.js — a server-side platform for rapid development. Node.js Data Storage: MongoDB — NoSQL database, ideal for dynamic data. MongoDB Testing: Jest — a tool for testing JavaScript applications. Jest Example: The startup "FastShop" used a combination of React and Node.js to build a basic e-commerce site in 3 months. MongoDB helped quickly set up the database to store information about products and orders. FastShop 1.2 Scaling Stage When the product starts attracting more users, tools that support business growth and high traffic loads are essential. Main tasks: Automation of Processes. Customer Data Management. User Behaviour Analysis. Automation of Processes. Customer Data Management. User Behaviour Analysis. Recommended tools: Infrastructure: AWS or Google Cloud for scalable servers. Analytics:: Google Analytics for tracking user metrics. CRM: HubSpot for customer management. Infrastructure: AWS or Google Cloud for scalable servers. AWS Google Cloud Analytics:: Google Analytics for tracking user metrics. Google Analytics CRM: HubSpot for customer management. HubSpot Example: The startup "Growly" integrated AWS Lambda for processing large volumes of data and connected HubSpot to manage its growing customer base. 2.Evaluation of Key Tasks Each startup has three core areas of operation, for which tools are selected: development, marketing, and management. 2.1. Development The choice of programming languages, frameworks, and testing tools plays a key role in the speed and quality of development. Recommended tools: Frameworks: Django (Python), Express.js (Node.js). Version Control: GitHub or GitLab. Frameworks: Django (Python), Express.js (Node.js). Version Control: GitHub or GitLab. CI/CD: Jenkins or GitHub Actions. Jenkins 2.2. Marketing Attracting customers and analysing traffic data require reliable marketing platforms. Recommended tools: Email campaigns: Mailchimp.

Maximising free plans Many SaaS companies offer free plans with basic features, which are sufficient for the early stage of a startup. Usage strategies: Careful selection of tools with optimal free features. Using multiple free services to cover different tasks. Examples: Slack: The free plan allows you to store up to 10,000 messages and use 10 integrations, which is sufficient for small teams.\ Trello: On the free plan, a startup can manage tasks with an unlimited number of users and up to 10 boards. Google Workspace: The free versions of Google Docs, Sheets, and Drive are actively used by startups for document management and data storage.
