Theres so many ways that I could answer this question but it would depend on knowing more about the situation.
There are many ways to find seed investors, mostly depending on your experience and network, (eg do you already have an existing network of investors?). If no, then you will be starting to build that from scratch. The good news is thats totally doable with tools like Angellist, Linkedin, etc.
Then you need a strategy on how to approach people especially if you are doing it cold. Some tips
1) Try to get referrals through common friends (linkedin is great for this). Investors get turned off by cold pitches so try to start strong if you can.
2) Have your pitch deck ready. Around 10 pages of attractive content to sell the dream. What problem are you solving? How? Size of market? Team? Product/traction so far? Why ou need the cash, etc. Happy to share a real deck one of my startups used (EcoMarket) that raised around 1M USD in total.
3) Hustle and sell like crazy. If you're going without an exiting investor network to tap into one strategy is to play the numbers. You are going to get a lot of no's: Dont be put off by that, but each time ask 1 thing you could improve on and most investors will take the time to reply if you are direct. Use that feedback to revise your pitch and rinse and repeat. Again, raised 1M USD+ this way myself.
Happy to share more details in a call.
