I am a mobile applications developer.
I have experience in building mobile apps for large international investment banks and small startups.
Where can I find potential clients? Especially small startups?
I am based in London, UK.
I am digital marketer, lead generation expert. I can provide you clients as per your needs globally. For more information, please mail your requirements at email@example.com
Tons of ways. LinkedIn groups, Facebook groups, Reddit groups. Post about it (if allowed) and just stay involved with the community, answer questions and such. You can also contact the group owners to have a permanent ad in their group for a commission (Or that the owner posts about it).
In my country we have multiple FREE support organisations that helps people create startups. They love to work with different companies to help their startups. To get in contact with that type of organisation could set you up so that most startups that pops up who needs an app, will be sent to you (if you offer maybe a discount to customers who comes from that organisation).
Then of course, a bit more complicated, the perfect customer care and satisfaction (no being super nice is probably not enough). Nothing beats word of mouth from customers who are blown away by how good you are.
