If you’re operating in the Software-as-a-Service business you need a legal team with expertise in working with SaaS companies, as well as one that understands the organisational and commercial challenges you face every day and throughout your growth journey.

Our expertise

At Clayden Law we specialise in supporting SaaS businesses as they start-up, scale and secure investment.

This work ranges from drafting, reviewing and updating terms and conditions; the day-to-day negotiation of contracts; and advising on data protection compliance.

Our specialist technology lawyers are drawn from the leading private practice firms, as well as senior in-house counsel roles across the sector. We work as an integrated part of your team.

Our fixed-fee retainer packages bring real peace of mind, coupled with market-leading expertise. Not only can you call on us at any time, as business owners (and members of the management team) you’re freed up to focus on building your business and preparing for a clean exit or the next funding round.


Nick Gibson, Sirenum’s Chief Operating Officer, says: ‘Clayden Law really understands SaaS businesses - not just the legal side but the commercial and organisational challenges, and the steps to take to get things right. Because of their involvement we have been able to improve the way we do things, relax (knowing we’re ticking the legal boxes) and be better equipped for growth and funding rounds. We cannot recommend their specialist experience in this field highly enough.’

‘Strengths are domain specialisation (knowledge), accessibility of resource, flexibility in approach, right-size delivery, calm and unfazed commercial negotiation style. Being a small team it doesn’t feel like you are paying for multiple resources when they are not all needed which can be an issue with other companies.’

‘Piers Clayden – Piers and his team have consistently provided quality, right-size advice and their expertise in Technology, SaaS and data privacy have been pivotal to us. I have also worked with Piers through complex client negotiations through which he has always provided a calm approach that gets the right results.’

‘Clayden Law is a practice focused on Information technology, data privacy and cybersecurity law. We are a start up SaaS business and Clayden Law provides services directly relevant to our industry and stage of development – as an added bonus they are also within our geographical area. Clayden Law has directly relevant expertise and experience which ensures that we get the most relevant advice at a great price. Nailing our terms and conditions, order form and maintenance and support SLAs at an early stage will reap significant rewards as we progress.’
