What internal controls should a scale-up have in place before Series B?

Before a Series B round, a scale-up should have documented financial controls, a functioning risk management framework, basic security and privacy controls aligned with relevant regulations, and clear ownership of governance across the organisation. Investors at this stage are no longer just backing a product or a team — they are evaluating whether the business can scale without breaking. Governance maturity is a direct signal of operational readiness. The sections below walk through each control area investors will scrutinise and what “good enough” looks like at Series B. If you want to talk through your specific situation, feel free to get in touch with us and we will be happy to help.

Why do investors scrutinise internal controls at Series B?

Series B investors scrutinise internal controls because they are deploying capital into a business that must now operate at scale, and weak governance creates financial, legal, and reputational risk that directly threatens their return. At this stage, due diligence moves beyond traction metrics and into operational infrastructure. Investors want evidence that the company can manage growth without losing control of its finances, data, or compliance obligations.

At Seed and Series A, investors largely tolerate governance gaps in exchange for speed and product-market fit. By Series B, that tolerance shrinks significantly. The funding amounts are larger, the regulatory environment across the EU is more demanding than ever in 2026, and institutional investors often have their own compliance obligations that require portfolio companies to meet minimum governance standards.

There is also a practical risk dimension. A scale-up that cannot demonstrate clean financial reporting, defined access controls, or a basic risk register is a company that could face a regulatory fine, a data breach, or a financial misstatement shortly after investment. None of those outcomes are acceptable to a lead investor writing a significant cheque. Internal controls are, in essence, the infrastructure that makes a business investable at this stage.

What financial controls should a scale-up have before Series B?

Before Series B, a scale-up should have segregation of duties in its financial processes, a monthly close cycle with reconciled accounts, documented approval workflows for expenditure, and financial reporting that is accurate, timely, and auditable. These are the baseline controls that allow investors and auditors to trust the numbers they are reviewing during due diligence.

Specifically, investors will look for the following:

Segregation of duties: No single person should be able to initiate, approve, and record a financial transaction without oversight.
Expense approval policies: Clear thresholds and documented sign-off processes for spending at different levels of the organisation.
Monthly financial close: A consistent process for closing the books each month, with variance analysis and management reporting.
Audit trail: Financial systems that log who did what and when, making it possible to reconstruct decisions if questioned.
Revenue recognition: Especially important for SaaS businesses, where deferred revenue and contract terms must be handled correctly under applicable accounting standards.

Many scale-ups at Series B still rely on a single finance hire or an outsourced bookkeeper. That is not necessarily a problem, but the controls themselves must exist and be documented regardless of team size. Investors are not just checking whether the numbers add up — they are checking whether the processes that produced those numbers are reliable enough to hold up under scrutiny.

What security and privacy controls do Series B investors expect?

Series B investors expect a scale-up to have a documented information security policy, defined access controls, a process for managing third-party risk, and basic privacy compliance aligned with GDPR. If the company handles sensitive customer data or operates in a regulated sector, investors will also look for evidence of alignment with frameworks such as ISO 27001 or NIS2.

Security and privacy have moved from “nice to have” to “table stakes” for EU-based companies. Regulatory requirements like GDPR, NIS2, and the EU AI Act mean that a data breach or a compliance failure is not just an operational headache — it is a material liability that can affect valuation and deal structure. Investors conducting due diligence in 2026 will often include a technical security review as a standard part of the process.

Security controls investors will assess

At a minimum, investors expect to see multi-factor authentication enforced across critical systems, a documented process for revoking access when employees leave, regular vulnerability management, and an incident response plan. The plan does not need to be elaborate, but it must exist and someone must own it.

Privacy controls investors will assess

On the privacy side, investors will look for a current record of processing activities, documented lawful bases for data processing, a process for handling data subject requests, and evidence that data processor agreements are in place with key vendors. A privacy policy that was written at founding and never updated is a red flag — it suggests governance has not kept pace with the business.

How mature should a scale-up’s risk management framework be by Series B?

By Series B, a scale-up’s risk management framework should be operational rather than aspirational. That means a maintained risk register, defined risk owners, a regular cadence for reviewing and updating risks, and evidence that risk information feeds into management decision-making. Full enterprise risk management sophistication is not required, but the framework must be active and demonstrably used.

The most common failure mode at this stage is a risk register that was created for a previous audit or funding round and has not been touched since. Investors and their advisors can spot a stale risk register quickly — the dates, the language, and the absence of any closed or escalated items are all signals that the document is decorative rather than functional.

A practical Series B risk framework typically covers strategic risks, operational risks, financial risks, and compliance risks. Each risk should have a named owner, an assessed likelihood and impact, and a documented mitigation or acceptance rationale. The cadence of review does not need to be weekly, but quarterly is a reasonable minimum for a company at this growth stage.

Continuous governance is the underlying principle here. Risk management is not a project that gets completed before a funding round — it is an ongoing organisational capability. Investors are increasingly sophisticated at distinguishing between companies that have governance and companies that have governance documents.

Should a scale-up have an internal audit function before Series B?

A formal internal audit function is not typically required before Series B, but a scale-up should have some form of independent control assurance — whether that is a periodic internal review process, an external audit of key controls, or a structured self-assessment against a recognised framework. The key is demonstrating that controls are tested, not just documented.

Most Series B companies are not large enough to justify a dedicated internal audit team. What investors want to see instead is evidence of honest self-assessment: that the company has looked critically at its own controls, identified gaps, and taken action to close them. A gap analysis conducted six months before a funding round, with a clear remediation plan and documented progress, is often more reassuring to investors than a pristine control environment with no evidence of testing.

Where external assurance is available — such as an ISO 27001 certification, a SOC 2 report, or a GDPR audit — it adds significant credibility. These certifications signal that an independent third party has reviewed the controls and found them to be functioning. They also reduce the burden on investors to conduct their own deep-dive technical assessments during due diligence.

How can a scale-up close governance gaps quickly before a funding round?

A scale-up can close governance gaps quickly before a funding round by prioritising the controls that investors will actually test during due diligence, assigning clear internal ownership for each gap, and using a structured framework to guide remediation rather than starting from scratch. Speed matters, but credibility matters more — rushed documentation that does not reflect reality will be identified during due diligence.

The most effective approach is to start with a gap assessment against the controls covered in this article: financial controls, security and privacy, risk management, and control assurance. For each gap, the question is not “how do we create a document?” but “how do we put a real control in place and provide evidence that it is working?”

Practical steps that move quickly without sacrificing substance include:

Assign control owners: Every control area needs a named individual who is accountable. Governance without ownership does not hold up under scrutiny.
Prioritise investor-facing controls: Focus first on the areas that will be reviewed in due diligence — financial reporting, access management, data processing records, and the risk register.
Use existing frameworks: ISO 27001, GDPR, and NIS2 provide ready-made control structures. Mapping your current state against these frameworks identifies gaps systematically and produces artefacts that investors recognise.
Document what actually happens: Policies and procedures should describe real processes, not ideal ones. Investors will interview your team — if the documentation does not match what people actually do, it creates more doubt than no documentation at all.
Get external support where needed: For regulated areas like information security and privacy, bringing in specialist support to accelerate remediation and provide independent validation is often the fastest route to a credible control environment.

Frequently Asked Questions

How long does it typically take to get governance controls investment-ready before a Series B?

The timeline depends heavily on your starting point, but most scale-ups need between three and six months to move from a fragmented control environment to one that will hold up under Series B due diligence. Starting the process at least six months before your anticipated raise gives you time to implement real controls, gather evidence of their operation, and course-correct if gaps are larger than expected. Leaving governance remediation until the final weeks before a round is one of the most common mistakes founders make — rushed documentation without operational substance is easy for experienced investors to identify.

What happens if investors find governance gaps during due diligence — does it automatically kill the deal?

Not automatically, but it does affect deal dynamics. Minor gaps with a credible remediation plan are generally manageable — investors may accept representations and warranties, add conditions precedent, or adjust valuation to account for residual risk. Significant gaps, particularly around financial controls or data compliance, are more likely to delay the process, trigger additional scrutiny, or result in unfavourable deal terms. The worst outcome is not having gaps — it is having gaps and no awareness of them, which signals to investors that the management team lacks the operational maturity to run a scaled business.

Which team member should own governance and internal controls at a Series B stage company?

At Series B, governance ownership is typically split across the CFO (financial controls), the Head of Engineering or a dedicated security lead (information security), the General Counsel or Data Protection Officer (privacy and compliance), and the CEO or COO (overall risk management and board-level accountability). If your organisation does not yet have all of these roles, the key principle is that every control area must have a named owner — even if that person is wearing multiple hats. Diffuse ownership, where governance is everyone's responsibility and therefore no one's, is one of the clearest signals of immaturity that investors look for.

Is ISO 27001 certification necessary before a Series B, or are there lighter-weight alternatives?

ISO 27001 certification is not a hard requirement for most Series B raises, but it is a significant credibility signal — particularly for B2B SaaS companies, businesses handling sensitive data, or those operating in regulated sectors. If full certification is not achievable in your timeline, a documented gap assessment against ISO 27001 controls, combined with a clear remediation roadmap, can demonstrate the same underlying intent. SOC 2 Type I or a structured GDPR audit can also serve as credible third-party assurance in the absence of ISO 27001. The goal is to show investors that an independent party has reviewed your controls — the specific framework matters less than the evidence of external validation.

How should a scale-up handle governance requirements that differ across multiple EU jurisdictions?

If your business operates across multiple EU member states, your baseline governance framework should be built around EU-level regulations — GDPR, NIS2, and any sector-specific directives — since these apply uniformly across the bloc. On top of that baseline, you will need to account for national implementation differences, particularly around NIS2 transposition, local employment law, and sector-specific licensing. The practical approach is to document your primary regulatory obligations in a compliance register, identify any jurisdiction-specific variations, and assign ownership for monitoring regulatory changes in each market. Investors with EU portfolio experience will expect this level of awareness, especially if your growth plan involves expanding into new member states post-investment.

What is the most common governance mistake scale-ups make when preparing for Series B?

The most common mistake is treating governance as a documentation exercise rather than an operational one — creating policies, risk registers, and control frameworks specifically for the funding round without embedding them into how the business actually runs. Experienced investors and their advisors are skilled at identifying the difference between governance that exists on paper and governance that is genuinely operational: they will ask your team members how processes work, look for evidence of controls being tested, and check whether risk registers reflect current business realities. The second most common mistake is starting too late, which forces a choice between delaying the raise or presenting a governance environment that looks rushed and unconvincing.

After Series B closes, how should a scale-up evolve its governance framework to stay ahead of future rounds?

Post-Series B, the priority is transitioning governance from a funding-round activity to a continuous organisational capability. That means establishing a regular cadence for risk register reviews, scheduling periodic control assessments, and ensuring that governance keeps pace with business changes — new products, new markets, new vendors, and new headcount all introduce risks that need to be captured and managed. As you approach Series C and beyond, investors will expect more formal structures: a fully constituted board with independent directors, a formal audit committee, and potentially a dedicated compliance function. Building those foundations incrementally after Series B, rather than scrambling before Series C, is the most sustainable and investor-credible approach.
