Startup legal support for founders building fast

Usually when the startup moves from idea to real commitments: a co-founder joins, a contractor or consultant starts building the product, you collect customer data, you launch a website or app, you sign a customer, or an investor starts asking questions. Those moments create ownership, liability, privacy, IP and decision-making issues that are much easier to sort out early. For example, before launch you may need website or app terms and privacy documents. Before bringing in contractors, you may need IP assignment wording so the company owns the work they create.

It depends on the business model, but common startup documents include a Founders Agreement or Shareholders Agreement, IP assignment documents, contractor or consultancy agreements, employment agreements, customer terms, Website Terms & Conditions, privacy documents and key commercial contracts. A startup raising capital may also need help with an advance subscription agreement, convertible loan note, term sheet or investor-ready company documents. The right bundle should match your stage, not just a generic checklist.

Start by checking who actually created the IP and whether the company owns it. Founders, contractors, agencies and early employees can all create code, designs, brand assets, content, customer lists or other material that the business depends on. Sprintlaw can help put IP assignment documents, contractor clauses and founder arrangements in place so the ownership position is clearer before you raise capital, sell the product or bring on more people.

If you are still early and want to set expectations between founders, a Founders Agreement can cover roles, ownership, decision-making, vesting, exits and what happens if someone leaves. A Shareholders Agreement is often used once the company structure and shareholdings are more settled, especially where investors or more formal governance are involved. Many startups need one of these before there is a problem, because founder disputes are much harder to solve when nothing was written down.

Yes. We can help with practical fundraise preparation, including reviewing or preparing advance subscription agreements, convertible loan notes, term sheets and shareholder documents. We can also help clean up the legal basics investors often look at, such as company ownership, IP assignments, customer contracts, privacy documents and contractor arrangements. The goal is to reduce avoidable friction before a raise becomes time-sensitive.

We work with startups across the UK, including SaaS and software companies, mobile apps, marketplaces, ecommerce brands, agencies, health and wellness businesses, fintech-adjacent services, food and beverage startups, education platforms and professional services businesses. The legal work usually turns on the same practical questions: who owns the product, how revenue is earned, what data is collected, who is on the team and what risks need to be covered before the next stage.

Yes. A lot of startups come to us after launch when the business is moving quickly and the legal setup has lagged behind. We can help review what is already in place, identify gaps and prioritise the documents that matter most. That might mean fixing customer terms, assigning IP from old contractors, formalising founder arrangements, preparing employment or contractor documents, or getting privacy paperwork in order.

Sprintlaw works on fixed-fee pricing where possible, so you know the cost before work begins. The exact quote depends on what you need, whether that is one document, a review, a fundraise document or a broader startup legal pack. If you are not sure where to start, you can request a free quote and we will help you work out the most sensible next step.
