Trustindex verifies that the original source of the review is Google. I've been a member of a Mastermind9 group for several months now after setting up my own business last year. The rigour and accountability this has brought is really helpful as well as the advice and resources we have access to. I feel part of a supportive community which really helps in the somewhat lonely world of running your own company! I'd highly recommend working with Pete, Sarah and the team.

Trustindex verifies that the original source of the review is Google. I joined Mastermind9 for support with growing my business. I have stayed with the group because I not only get business support, I also get encouragement, new ideas, and the enjoyment of sharing ideas and helping other like-minded business owners. The weekly accountability sessions are mandatory and keep me on track and consistent with my to-do list, which will ensure I meet my targets each quarter. Each monthly session, there is a realisation that can help me push forward month by month. Thanks team!

Trustindex verifies that the original source of the review is Google. I met Pete and Sarah when I was a few months into starting my own business. I knew instantly I wanted to work with them and would value their support immensely. Being part of Mastermind9 and being able to share my experiences, share my worries and blockers - with a team of people who all knew what I was going through - was/and has been amazing. I wanted to be part of M9 for the support, experience and mentorship side of businesses. Pete and Sarah make you feel instantly at home, no question is a stupid one, no struggle is too much and no mindset can't be changed. I would recommend anyone wanting to start a business, having had an established business, or just needed that community to talk about your business in, to join one of the guys courses. I'm so grateful for all they have done for me 🙂

Trustindex verifies that the original source of the review is Google. Running a business can feel like an uphill battle, but joining a mastermind group changes that. I’ve been with Mastermind9 for three years, and the transformation has been profound. Before joining, I struggled to shift into a true "CEO" mindset. I initially worried about losing an afternoon every month, but it has quickly become the most valuable time on my calendar. Having knowledge about businesses allows you to tackle your own challenges with clarity and foresight. You truly have a board of people who have got your back. Together you commiserate and celebrate! Pete and Sarah are amazing. They facilitate with such insight, always dropping "golden nuggets" of advice exactly when you need them. I wouldn't have pushed my boundaries or achieved this level of growth without their support. I highly recommend Mastermind9 for strenght and clarity in business.

Trustindex verifies that the original source of the review is Google. I joined Mastermind9 around 5 months ago now, at that point in time I was just leaving my previous role, didn't really have a product or a strategy and jumped straight into a Plan90 Q1 planning session with Pete & Sarah. I can only say that it has been the best experience, and helped me catapult my startup from 0 to 15 customers really quickly. The feedback, guidance, planning and accountability that founders get from Mastermind9 AND the cohort of other founders in the same situation is second to none! If you're at the start, struggling or hitting a plateau in your business I recommend you join.

Trustindex verifies that the original source of the review is Google. I started working with Pete and the team at Mastermind9 in January this year. I love the energy, collaboration and I really appreciate the Friday catchups with my accountibility buddy, it really helps to maintain focus on the goals that we are setting for the business. I highly recommend Mastermind9 for any business leaders regardless of size or structure.

Trustindex verifies that the original source of the review is Google. Mastermind9 has helped me transform my business. As a sole business owner it was hard to challenge myself and understand, tactically and strategically how I could help grow. Peter, Sarah and the Team are fantastic and always on hand to offer support. The group I am in is brilliant, we're not afraid to challenge the status quo and the breadth of knowledge and experience has truly helped turn things around from both the business and my time. Couldn't recommend enough.

Trustindex verifies that the original source of the review is Google. I joined Mastermind9 in June 2025 because, although my business was doing OK, I knew it could do better, but I wasn’t sure how to do it by myself. The M9 process of accountability and other likeminded business owners, but with totally different skill sets is incredible. This isn’t just business coaching, it’s a whole board of talented people pushing you to be the best you can be. Since joining M9, I’ve got a clear focus on how to grow my business and I’m seeing incredible results. I’ve had quarter on quarter increases in revenue and I’ve delivered more in my business than I had in the 2 years prior when I did it alone. The accountability groups are great and I always come away feeling focussed and I have clarity. I’d recommend M9 to anyone who wants a little help navigating the next step in growing their business and wants a community behind them to cheer them on. Pete and Sarah are wonderful humans with so much knowledge, passion and energy and truly want the best for you and your business.

Trustindex verifies that the original source of the review is Google. Being a CEO can be isolating and lonely there’s no one above you to challenge your thinking or keep momentum moving. That’s exactly where Mastermind 9 makes such a difference. What Mastermind 9 offers is incredibly powerful: access to a network of professionals across a wide range of disciplines, alongside peers facing similar challenges. It’s not just advice it’s practical, shared problem-solving with real accountability and support behind it. And that accountability is what truly sets it apart. Pete , Sarah are such a supportive sounding board genuinely lovely people who challenge, encourage and have your back every step of the way. They genuinely care.

Trustindex verifies that the original source of the review is Google. We've been in the M9 squad for 18 months now, 13 years into business. We joined because we had just lost a huge contract, we were needing a safe space to process what happened, the impact and how to get back on track. Mentally, since Covid, business has been HARD. I took a leap of faith and havnt looked back. The tough times that just kept coming but were met with support, knowledge, solutions and frankly a place to lay out all our vulnerability. M9 has helped us realise what we want out of business, provided a clear path on how to achieve it and accountability to keep pushing through. I have met and are now friends with some incredible business owners that inspire us everyday to be and do better. We wouldn't be where we are today without Peter, Sarah and the team, and we've got so much further to go, which I know we can achieve with this shared wealth of knowledge and support.

What is Mastermind9?
Mastermind9 is an award winning business growth programme, with plans from £150 to £575 a month depending on your stage.
Think of it as your own board of directors, business owners who’ve built one themselves, telling you the truth.
- Surrounds you with ambitious business owners who push you to think bigger and be braver
- Gives you the structure and accountability to actually follow through on what matters most
- Keeps every conversation confidential under NDA, so you can be completely honest
- Turns isolation into collaboration, because growing a business shouldn’t feel lonely
That’s why 91% of our members grew last year.
Rooms are kept deliberately small. Once a group’s full, it’s closed until the next one opens.
How Our Mastermind Groups Work
Quarterly Planning. Half a day, every quarter, to reset and set your next 90-day goals.
Monthly Sessions. A hand-picked group tackles your real challenges. You leave with clear next steps.
Weekly Accountability. A sharp 20-minute check-in to keep the momentum going between sessions.
Community & Events. Workshops, guest speakers, and a network that’s got your back.
Private Online Hub. Resources, recordings, and a member community that never switches off.
Pete takes every intro call himself, so there are only so many slots each week.
