Scaling a startup from Series A to Series B is like adding new floors to a high-rise building. Before construction begins, engineers conduct a comprehensive inspection to ensure the foundation, wiring, and structural integrity can handle the added load. If weaknesses are identified—whether in the foundation or infrastructure—they must be addressed before further growth can proceed safely.In the world of startups, Tech Due Diligence serves a similar purpose.
As a startup moves toward Series B, it’s essential to assess whether the existing technology stack, security protocols, and development processes are robust enough to handle rapid growth, increased user loads, and evolving business complexities. Without this critical evaluation, startups risk encountering system failures, security vulnerabilities, and operational inefficiencies—much like a building that wasn’t prepared for vertical expansion.By identifying and addressing these gaps early, tech due diligence ensures that startups are ready for their next stage of growth, just as a well-inspected building can safely scale to new heights.
Between rapid growth and tight deadlines, changing requirements and lack of long-term focus, startups build with MVP mindset and keep building on top without strategic pause and accumulate technical debt. As they sprint towards PMF and push products out quickly, they may take shortcuts that become liabilities when scaling up. This can lead to outdated systems, fragile integrations, and inconsistent data that hinder further growth.
The Digital Transformation Imperative
The digital transformation wave has accelerated across industries, making technology the backbone of most modern businesses. For startups, this shift means that their technical infrastructure is no longer just a support system but a core driver of value and competitive advantage. Investors are increasingly aware that a startup’s ability to scale, innovate, and adapt in this digital-first world is intrinsically tied to the quality and resilience of its technology stack. Additionally, AI adoption is driving a 360’ shift in the practices used by startups to accelerate growth, optimize workflows, and gain a competitive edge. As startups transition from Series A to Series B funding, demonstrating a solid technical foundation has become a key differentiator for securing investor confidence.
Shifting Left : Bringing Tech Due Diligence to the Forefront
The concept of “shifting left” in software development emphasizes addressing issues earlier in the process to reduce risks and inefficiencies. This principle is now being applied to the investment process as well. Conducting thorough technical due diligence early on allows startups to:
- Identify and Address Technical Debt Proactively – Preventing long-term inefficiencies and bottlenecks.
- Ensure Scalability of Architecture and Infrastructure – Preparing systems to handle increased user loads and complexity.
- Validate Security Measures and Compliance Readiness – Mitigating risks and ensuring adherence to regulatory standards.
- Assess the Efficiency of Development Processes and Automation – Optimizing workflows to improve development velocity.
By addressing these aspects early, startups can present a more compelling case to Series B investors, demonstrating foresight and a solid foundation for future growth.
Security: Protecting Against Digital Threats
In the current digital landscape, cybersecurity has become a paramount concern for investors. Companies involved in financial transactions are particularly vulnerable to ransomware and cyberattacks. One of the most common and disruptive attacks is botnet-based DDoS (Distributed Denial of Service), where attackers target companies during peak business hours, significantly impacting DAU/MAU metrics, user experience, and Net Promoter Scores (NPS).
Several overlooked vulnerabilities can expose startups to such attacks:
• Unpatched Software – Leaving systems open to known exploits.
• Poor Memory and Privilege Management – Increasing the risk of unauthorized access.
• Hardcoded Credentials – Providing easy entry points for attackers.
Startups that demonstrate a proactive approach to identifying and mitigating security risks instill confidence in investors and protect their long-term reputation.
Scalability: Preparing for Rapid Growth
As businesses experience sudden surges in user traffic and data volumes, the ability to scale efficiently can make or break a company’s success. Cloud-native infrastructure and microservices architecture have become essential for startups aiming to handle fluctuating workloads and accommodate rapid growth. However, scalability challenges extend beyond just technical infrastructure:
• Performance Under Load: During peak times, such as flash sales or viral marketing campaigns, systems must maintain responsiveness to ensure a smooth user experience.
• Data Management: As user bases grow, efficient data storage and retrieval become crucial for maintaining performance and controlling costs.
• Global Expansion: Companies entering new markets must address geographical scalability, including data localization and latency issues.
• AI and Machine Learning: The increasing adoption of AI requires scalable computational resources to handle complex algorithms and large datasets.
Investors are particularly interested in startups that can demonstrate their ability to scale operations efficiently, as it directly impacts long-term viability and market competitiveness.
Compliance: Navigating an Evolving Regulatory Landscape

In an era of increasing regulatory scrutiny, compliance has become a make-or-break factor for startups seeking investment. The regulatory landscape is constantly evolving, with new laws and standards emerging across different jurisdictions. Startups need to stay ahead of these changes to mitigate legal risks and maintain investor confidence.
Key compliance challenges for startups include:
• Data Protection: With regulations like GDPR and CCPA, startups must ensure robust data governance and privacy measures.
• Industry-Specific Regulations: Sectors such as finance and healthcare face stringent compliance requirements that startups must navigate.
• AI Regulation: Emerging AI-specific regulations, such as the EU AI Act, require startups to demonstrate responsible AI development and deployment.
• Cross-Border Compliance: As startups expand globally, they must adapt to varying regulatory requirements across different countries.
Startups that build compliance into their core operations reduce regulatory risks and demonstrate a commitment to ethical and responsible growth—making them more attractive to investors.
Engineering Efficiency: Driving Speed and Innovation
In the competitive startup landscape, engineering efficiency is a critical factor for investors evaluating a company’s potential for growth and innovation. Efficient engineering practices directly impact a startup’s ability to iterate quickly, manage costs, and deliver value to customers.
Key aspects of engineering efficiency include:
• Development Velocity: The ability to rapidly develop and deploy new features without compromising quality.
• Resource Optimization: Efficient use of computational resources and developer time to maximize output.
• Automation: Implementing CI/CD pipelines and automated testing to streamline development processes.
• Technical Debt Management: Balancing quick delivery with sustainable code practices to avoid long-term inefficiencies.
• AI-Augmented Development: Leveraging AI tools to enhance developer productivity and streamline workflows.
Investors are increasingly focusing on metrics that demonstrate engineering productivity and efficiency, as these directly correlate with a startup’s ability to innovate and respond to market demands.
Technical Debt: A Hidden Threat to Scaling
Technical debt has emerged as a critical concern for investors, as it can significantly impact a startup’s agility, innovation capacity, and long-term viability. In the AI era, all technical debt is essentially becoming AI technical debt, affecting a company’s ability to leverage cutting-edge technologies.
Key aspects of technical debt that concern investors include:
• Development Cycle Impact: Technical debt can slow down development cycles, forcing developers to spend more time on bug fixes and navigating complex codebases.
• Innovation Hindrance: Resources diverted to maintaining current systems due to technical debt can stifle innovation.
• Scalability Challenges: Accumulated technical debt can make it difficult for startups to scale their systems efficiently.
• Security Vulnerabilities: Outdated or poorly maintained code can lead to security risks, exposing the company to cyber threats.
• Cost Implications: Technical debt can account for 20% to 40% of the value of a company’s entire technology estate.
