Mastering due diligence: Navigating the intricacies of investment rounds in tech start-ups from Seed to Series A


Unearth the nuances of due diligence with insights from seasoned founders, arming your tech start-up with the knowledge to secure your next investment.

The journey of a tech start-up from idea to reality is often dotted with challenges, opportunities, and learning curves. A significant part of this journey is raising funds, a process that comes with its own unique set of demands. Among these, due diligence is an aspect that can be quite intricate and demanding, yet it's one of the most pivotal parts of securing investment.

Understanding due diligence

Due diligence is the rigorous assessment that potential investors conduct to confirm the viability and value of your start-up before investing. The process is much more than just a fact-checking exercise. It's an opportunity to showcase your business’s potential, strengths, and resilience.

While due diligence is crucial at every investment stage, its nature and depth can change significantly from the Seed to Series A rounds. During the Seed round, the focus is often on the idea, the founder(s), market size, and potential for growth. As you move to the Series A stage, the focus shifts to financials, traction, technology, user engagement, and revenue streams among other things.

Assembling the right team

Who you have on your team during due diligence can significantly impact its outcome. Two roles, in particular, stand out: the project manager and the CFO. The project manager, often someone from the founding team, keeps the process running smoothly, ensuring all information is readily available and deadlines are met.

On the other hand, a competent CFO can be a game-changer. They can help make sure the company’s financial health, plan for contingencies, and give potential investors confidence in the management's financial acumen.

The importance of a data room

A data room is a secure location where you store documents that potential investors can review during due diligence. Managing it efficiently can demonstrate your start-up’s organisational skills and transparency. An optimised data room not only speeds up the due diligence process but also reduces the risk of deal fatigue.

The value of strong financials

Having robust historical financial numbers, clear explanations, and sound assumptions in your forecast model are vital. These financials should dovetail with your pitch deck and overall strategy, demonstrating your start-up's financial health and growth potential. Investors look for a clear trajectory of growth, backed by reliable data and sensible forecasts.

The customer profile

Understanding your customer has become a focal point for investors. They're keen to explore the intricacies of your customer base, from their behaviours to their loyalty drivers. Cohort modelling, which segments customers based on specific characteristics, offers insights into how different groups engage with your product. Presenting your customer data in a cohort view can significantly enhance your attractiveness to investors, especially if the data showcases positive trends. Key metrics like net revenue retention and churn rate further shed light on your start-up's health from a customer's viewpoint. For investors, a start-up that's in tune with its customer profile signals sustainable growth potential.

The role of a tax health check

A tax health check, often overlooked, can make your start-up more attractive to investors. This review of your company's tax situation can identify potential issues before they become problems, demonstrating to potential investors that your business is compliant, aware of its obligations, and ready for growth.

Lessons learned in navigating due diligence

Understanding the due diligence process and its implications is one thing, but gleaning insights from those who have been there and done that is invaluable. Experienced founders emphasise the importance of preparation, clear communication, and patience. After all, due diligence isn't just a hurdle to overcome; it's an opportunity to shine.

Preparation is key. Anticipate what investors will want to see, organise your data room meticulously, and prep your team thoroughly. That's half the battle won.
