It's important to know the players in the space and what they're good at.

AngelList - very tough to raise funding and connect with people. There is a lot of saturation and barriers to connect (you need to have them following you or get intros from existing connections).

LinkedIn - work on your profile, post regulatory and garner support for your posts to position yourself as a thought leader whilst giving interesting status updates on your business. You can search LinkedIn through the "advanced" search tool to find angels in your city. Connect with a few, ask for advice and to meet for coffee. If they like you, they will help and usually know other angels. Strike for Angels who know the market problem.

SeedInvest - all the investments need to pass the screening committee and the partners. Thereafter there is some heavy due dill whence from the team and CrowdCheck. Only a handful of vetted deals are available and they co-promote to their investor pool. If it's a really good deal they may back the deal with $200k of SeedInvest's own capital once you pass $250k in fundraising. NOTE: they're a registered broker-dealer. They take 6.5% of capital raised but all the investors are accredited.

There is also OurCrowd, Crowdfunder, SeedEquity... It also depends where you are in the world as in the UK, there are some amazing tax-breaks for Angels and VCs.
