Sell-Side Technical
Due Diligence Prep & VDD

A comprehensive data-oriented approach for minimizing risks and maximizing valuation

Sell-Side Tech Due Diligence|

Why Is A Sell-Side Technical Due Diligence Important?


Sell-side tech due diligence is an assessment that helps a seller or a company with readiness. Still, more importantly, it helps surface issues before buy-side diligence, allowing them to understand potential concerns and often time to rectify before a buyer gets involved.

The result is a much more streamlined process for the buyer with fewer surprises. The seller benefits from better readiness, a less painful diligence process, and typically a higher value deal or at least a fair valuation price.


Sell-side technical due diligence can help eliminate potential deal killers, saving everyone time and costs.

What Are the Benefits Of A Sell-Side Technical Due Diligence?

Top benefits and reasons companies conduct sell-side technical due diligence.

  1. Explore Risks Early: Helps the seller uncover issues and potentially resolve or implement a plan to mitigate them.

  2. Practice Makes Perfect: A sell-side helps a team practice and exercise what they need to do. This is especially important for teams that have not been through a similar process.

  3. Diligence Is A Demanding Exercise: Having gone through one helps make the future process for potential buyers easier where the necessary documentation and data are prepared and ready. The headstart preparation also makes it easier for the team.

  4. Uncover Blind Spots: Assessing oneself with an external unbiased view can provide an advantage in pointing out blind spots that may not be visible to the team.

  5. Increase Appeal: Being proactive and ready indicates commitment that makes sellers/companies more appealing to potential buyers.

  6. Trusted Documentation: The resulting reports are helpful to both the buyers and sellers. The buyers will have a VDD (Vendor Due Diligence) report ready for their consumption, and the sellers will have an internal report with improvement opportunities to address.

We take a friendly, pragmatic, and strategic 360 holistic approach to help prepare a company for a potential buy-side technical due diligence. The process is structured to cover hidden concerns and outline a stack-ranked set of optimizations for better readiness while we’re helping the team prepare.

The due diligence and reports are data-driven, with quantifiable benchmarks and dual benefits. On the one hand, they provide concrete and comparative data for the company to understand its current state. Conversely, the data is presented in a VDD report, allowing the acquirer to get a measurable and healthy 360-view of the company.


The exercise thoroughly examines the overall suitability and health of the technology and its ability to evolve to accommodate the business strategy and technology landscape changes.


It explores the business and technology strategy, roadmap, software architecture, code health, team capabilities, software development lifecycle, deployment capabilities, IT infrastructure, security, services, and leadership.

Our approach combines human, machine, and tools using senior technology practitioners and CTOs with solid business acumen. Benchmarks are provided throughout proprietary software for industry and best practices comparisons. We focus on partnering with the company and providing them with clear, pragmatic guidance, practical risk mitigation, and preparedness for potential buy-side diligence.

Years of execution and experience working with investors and companies and hands-on with teams globally provide us with the experience to make the process painless for the team while providing them the most value.
