Product's Tech Side Review

At Upsilon, the due diligence methodology is based on reviewing and evaluating 5 key tech areas of the project. From our experience, these areas most fully cover the project's tech aspects and affect the amount of future effort and investments needed for its development and scaling. They are:


Hiring people with the right expertise can take time and effort, depending on how complex and modern the project stack is. And this, in turn, can slow down the formation of teams and product scaling.


Since time-to-market is a top priority factor for any startup, future success heavily relies on onboarding - or how quickly the team can grasp the business and tech specificities of the project and start coding.


By reviewing the project's code, architecture, designs, and all processes related to testing and deployment, you can be sure that you are investing in a quality-end product that functions how it should.


Most startups focus on stunning product design and killer features while reliability often fades into the background. For you, as an investor, a minute of downtime and negative user feedback can cost thousands of dollars.


Startups usually have fewer resources to enforce product security. The bigger the product grows, the greater the damage can be from a security breach. Uncovering vulnerabilities during the tech audit will prevent your business from money and reputation losses.

Quality Criteria Evaluation

Each tech area is determined by several criteria it consists of. We assess those criteria in two aspects: the current level and the complexity of fixing. As a result, each criterion is assigned a certain value of the "Health" indicator.


Project’s Health Score

Based on the "Health" of all criteria and tech areas, we derive an overall "Health Score" for the project.


The Audit Report

We prepare the tech audit report, including all calculations, risks evaluation, assumptions, and recommendations.

What is technical due diligence?

Technical due diligence is a process that takes place during business mergers and acquisitions. It involves a comprehensive review, assessment, and verification of all technical details related to the acquisition target’s product, such as architecture, code quality, security, and licensing, so that informed decisions can be taken regarding investments.

Why is tech due diligence important?

For most business buyers, the primary goal of a tech audit is to identify risks and potential costs that could impact the business and consider them when it comes to price. But there is another advantage that sometimes remains pushed to the background. Assuming the deal is being completed with growth in mind, a comprehensive tech audit can provide a good idea about how quickly and smoothly growth can be achieved.

Here are key reasons to conduct technical due diligence before M&A or seed funding:

  • Understand the current quality of the product's tech side;
  • Assess potential risks and pitfalls;
  • Evaluate the product's growth potential;
  • Predict future costs of product scaling with more accuracy.

Businesses and startups can also benefit from technical due diligence. It's an invaluable tool for founders, ensuring the original concept stays on track while providing direction toward success.

What are the stages of tech due diligence at Upsilon?

Technical due diligence is an ever-evolving process whose structure may vary from case to case depending on many factors. Our experience ranges from clients that have already built a product relying on our expertise as a tech partner to third-party consultants hired for code review (identifying strong and weak points of a product). Regardless of the type of cooperation, we split the tech due diligence process into six main stages:

1. Preparation

An initial step includes signing up a letter of intent (LOI) and non-disclosure agreement (NDA) to put confidence at the core of the process.

2. Kick-off call

At this stage, all parties better understand the product: its goals, market niche, and customer value proposition. At a high level, information about the technical side of the product is also provided. Then participants discuss all important aspects of the due diligence process, including timelines, the scope of work, documentation transferring, etc. After laying out these terms, the acquisition target’s team starts preparing documentation for review.

3. Documentation review

At this stage, our team thoroughly examines all the documentation provided. This process includes reviewing the existing architecture, code, integrations, and tech solutions and covers such areas of the project as hiring, onboarding, reliability, and security.

4. Meetings

Once the documentation analysis is complete, our team starts reviewing the technical side of the product in action. This stage usually involves performance testing and conducting interviews with developers.

5. Follow-up

Our experts prepare a document with intermediate assessment results and a list of questions for the business acquirer and the product team. All parties discuss the paper, and feedback is collected and quickly analyzed. Additional review-test iterations are made if necessary.

6. Reporting

The result of tech due diligence is the tech audit report based on document screening, testing, and meetings with stakeholders. The document includes all calculations, risks evaluation, assumptions, and recommendations regarding the quality of the reviewed product.

What is the due diligence report?

The tech due diligence report is a document providing investors with an in-depth analysis of the technical side of the product (or the startup as a whole) they will acquire to help them make the right decisions before moving forward with a deal.

A comprehensive due diligence report might include the following sections: 

  • Executive summary;
  • Methodology explanation;
  • Project quality evaluation by criteria;
  • Disambiguations - findings and recommendations;
  • Relevant documents (if needed);
  • Appendices.

How much does due diligence cost?

Costs for due diligence can range widely. Excluding the fees of both the buyer’s and seller’s teams, tech due diligence price might vary from $5,000 to $20,000 and even more depending on two factors: the complexity (and tech specificity) of the project and the number of review-test iterations needed to achieve the desired state of evaluated components. In short, conducting due diligence can be expensive and time-consuming, but potential risk avoidance outweighs it.
