We built our businesses riding the wave of the internet.
You have AI to surf.
Generative AI, Large Language Models, and Autonomous Agents are fundamentally transforming how we interact with computers. The opportunities are monumental, while the capital and labour required are lower than ever.
Small, focused teams are now building products that generate hundreds of millions in revenue. The pace of change is incredible, and you have a front-row seat to shape what comes next.
Your outgoings are low, your financial commitments are few, and your capacity to learn is at its peak. There is no better time to take a calculated risk on an idea you believe in.
Founder, Clear Books & Countingup
Tim started creating software in his teens. Now he's founded Sixthform to connect the next generation of founders with capital and mentorship.
Tim built Clear Books, one of the UK's first online accounting platforms, then launched business account Countingup, which now serves over 100,000 customers and has processed over £10 billion in transactions.
Led by Tim, the Sixthform network introduces founders to seasoned angel investors. Each angel in our network makes their own independent investment decision for every opportunity. We are not a fund and do not make collective decisions.
We know raising your first investment can seem complex. We’ve designed our process to be transparent and straightforward, so you can focus on building your business.
You submit your application through our website. Your plan is shared privately and then reviewed independently by the angel investors in our network.
If an investor sees a potential fit, they will contact you directly from their personal email to schedule an informal chat. Their goal is to get to know you and your vision. A 'no' from one investor doesn't prevent another from moving forward.
If an investor decides they want to invest, they will typically act as the "Lead Investor." They will work with you to agree on the key terms (like valuation) and provide you with a simple, plain-English Term Sheet. This document outlines the investment offer and gives you certainty and momentum.
With a signed term sheet from your Lead Investor, your main job is to "fill the rest of the round." We make this easy. Your Lead can make personal introductions to other trusted angels in our network, who can then make their own independent decisions to invest on the same pre-agreed terms.
Once all investors have independently committed to the round, the final step is just paperwork. To make this easy, your Lead Investor will help you coordinate the administrative process. They can liaise with a single law firm to ensure all the separate investment commitments are included in one simple set of documents, making the final step as painless as possible.
If you have the prototype and the plan, we want to hear from you.
