Networks operate on an invitation-only basis. If you would like to become a member of a specific network you will need to request an invite from the network directly. Please note that network membership varies: some are closed to new members, some are very selective about their membership and some will happily accept any investor. See each network's description and respective website for their specific policies regarding membership.
If you want to become an active business angel and share your experience of business with a growing company you should consider joining one or more networks and attending their pitch events.
However, if you are looking to co-invest alongside lead investors instead you have come to the right place.
If you are working with a business angel network (or a private equity group or similar) and want to have access to the capital on offer from SyndicateRoom members, you can ask the network to introduce your company to us.
