Hey everyone,
 
I’m looking for recommendations or to connect directly with a marketing team / agency that genuinely understands the Forex trading space — especially community-led growth.
 
I run many public XAUUSD signals Telegram channel that has grown organically to 12,000+ members over the years (since 2020). No ads, no clickbait, no fake screenshots. The channel is completely free and will stay that way because the core idea has always been transparency and live testing rather than selling promises.
 
A few things about the community:
 
• Signals focused only on FX & XAUUSD
 
• Consistent average accuracy around ~78%
 
• Clear risk management & lot sizing shared with every setup
 
• Priority is always capital protection, not overtrading
 
• Everything is public so anyone can track performance in real time for as long as they want
 
The growth so far has been word-of-mouth and organic, but now I want to scale this community responsibly and reach 100,000+ free members this year without turning it into a hype machine.
 
I’m not looking for generic social media marketers. I’m specifically interested in people/agencies who:
 
• Understand traders, not just traffic
 
• Can grow communities ethically and sustainably
 
• Know how to position transparency as a strength (not fake luxury marketing)
 
• Have experience with Telegram / Instagram / Reddit / Trading communities
 
If you’re a marketer in this niche, or you’ve worked with someone solid before, I’d really appreciate guidance, referrals, or a conversation.
 
Thanks in advance 🙏
 
Happy to share more details in DMs.
