Jessica JohnsonSeries 23 of Dragons' Den launched on BBC One on 29 January 2026, and with seven episodes already aired — including guest dragons Gary Neville and entrepreneur Susie Ma — the show has reignited national conversations about startup investment. But behind the television drama of accepted and rejected pitches lies a serious legal and financial reality: most founders who face investors are dangerously unprepared for due diligence.
What Dragons' Den Series 23 revealed about investor scrutiny
The 2026 series introduced four guest dragons alongside regulars Peter Jones, Deborah Meaden, and Touker Suleyman. Gary Neville's participation as guest dragon brought particular attention to sports business ventures, while REFY CEO Jenna Meek applied a sharp lens to founder credibility and brand positioning.
What viewers may not notice behind the pitch theatre is the extensive due diligence process that follows any expressed interest. When a dragon says "I'm in", that is not a binding agreement — it is the start of weeks of legal and financial investigation that frequently results in the offer being withdrawn or significantly renegotiated.
According to venture capital industry data, approximately 40% of deals agreed on Dragons' Den are never completed after due diligence reveals undisclosed liabilities, IP problems, or governance issues. For founders watching at home, this is the real lesson from the show.
The five legal checks every startup needs before investor talks
Whether you are pitching on television or approaching a local angel investor, the same legal framework applies. A specialist business lawyer can help you prepare in advance — making due diligence faster, cheaper, and more likely to result in a completed deal.
1. Company structure and share cap table
Investors will immediately request your shareholders' agreement and cap table — a document showing who owns what percentage of the company. Many early-stage founders have informal arrangements with co-founders that have never been formalised in a shareholders' agreement. This creates legal uncertainty about control, dividends, and exit rights.
Before any investor conversation, ensure your company is properly incorporated, shares are fully issued, and any co-founder arrangements are documented in a legally binding agreement.
2. Intellectual property ownership
Does your company actually own its technology, brand, and content? This is one of the most frequent deal-breakers in due diligence. If your product was developed by contractors or employees without proper IP assignment agreements, the company may not own what it is selling.
A thorough IP audit — covering trademarks, patents, software copyright, and trade secrets — is essential before approaching investors. In the UK, unregistered IP rights can create significant ambiguity.
3. Employment contracts and equity incentives
If you have employees, investors will scrutinise their contracts for restrictive covenants, confidentiality obligations, and notice periods. They will also want to see any equity incentive schemes — such as Enterprise Management Incentives (EMI options) — properly documented and HMRC-approved.
Poorly drafted employment contracts can create significant liabilities that reduce the company's valuation or block a deal entirely.
4. Outstanding liabilities and regulatory compliance
Investors conduct thorough searches for CCJs (County Court Judgements), tax liabilities, and regulatory penalties. If your company operates in a regulated sector — fintech, health, food, consumer products — compliance status is fundamental to valuation.
A pre-investment legal review should include a liability search and compliance audit. Companies that discover these issues late typically face compressed timelines and reduced valuations.
5. Term sheet and investment agreement negotiation
The term sheet — the document setting out the commercial terms of investment — is not standard. Every clause matters: valuation methodology, anti-dilution provisions, information rights, board composition, liquidation preference, and drag-along rights.
Most first-time founders do not have the experience to negotiate these terms effectively. A lawyer who specialises in startup investment can identify clauses that are unfavourable in the long term — even if the headline valuation looks attractive.

The real cost of not preparing
Dragons' Den makes investment look fast and dramatic. The reality is slower and more technical — but also more winnable with the right preparation. Founders who invest in legal due diligence before approaching investors typically close deals faster, at better valuations, and with fewer surprises.
The cost of a pre-investment legal review — typically £1,500 to £5,000 with a specialist UK startup lawyer — is almost always recovered in the form of better deal terms or avoided deal collapse.
With Series 23 of Dragons' Den driving a surge in startup and investment interest across the UK, there has rarely been a better moment to get your legal foundations in order. Whether you are pitching locally, applying to accelerators, or considering crowdfunding, the due diligence checklist is the same.

Where to start
If you are preparing for investor conversations in 2026, prioritise these steps:
- Have a solicitor review your company structure and shareholder agreements
- Commission an IP audit if your product relies on technology or brand
- Ensure all employment contracts are compliant and restrictive covenants are reasonable
- Check your tax position with HMRC — particularly if you have deferred payments
- Prepare a data room with all key documents before the first investor meeting
Preparation is not just about impressing investors — it is about protecting yourself. The legal agreements you sign when raising investment will govern your company for years. Getting expert advice early is the single highest-return investment a startup founder can make.
