I've been burned by cold email before and didn't want to be known as the "cold email guy" in my space. (Self limiting beliefs and all). I've been sourcing all of my leads through social media and referrals. I'm also extremely cautious when it comes to my reputation, partnerships, and client relationships. Jun is extremely professional, highly communicative, and detail oriented. This definitely is a growth partner-relationship, not a business-vendor relationship.

Results wise... averaging a 2-4% POSITIVE OVERALL reply rate which is insane. My sales teams calendar is full, the sharks are fed, and business is good. 138k closed attributable to cold email. If you're on the fence, let this be a message, the ROI is there.

Worked with Jun on cold email and he walked me through building the entire end-to-end infrastructure. It's the exact same setup he runs himself, which got him 7-8% reply rates and 50+ booked calls in August alone. What stood out most was the approach. It's completely different to what everyone else in cold email is doing, and I think that's exactly why it performs the way it does in a market this saturated. If you're still deciding who to work with for cold email, you won't regret working with Jun. 100% recommend.

I'd highly recommend Jun to anyone looking to get better results from cold email. One of the things that stood out to me is that he actually runs the exact system he sells. Nothing he talks about is theory. It's based on what he's doing himself and what he knows works. He also went much deeper than just giving me templates, tools and tactics. He explained the psychology behind why people reply and how important timing is. His outreach is built around real signals, so messages are landing when the prospect actually has a reason to care. The messaging itself is simple and low friction. It gets replies without needing to constantly chase people or put pressure on them. It's a completely different approach to what I see most people doing with cold email. I also really appreciated how open Jun was about the thinking behind everything. He didn't hold back information or keep certain things vague just so he could sell me something later. He's straightforward to deal with, knows his stuff and there was never any pressure. If you're considering working with someone on cold email, I'd definitely recommend speaking to Jun first.

Jun has been fantastic to work with. He's done an excellent job setting up and managing our email marketing infrastructure, making the entire process smooth and stress-free. Excited to continue working with him!

Had a consulting call with Jun where he walked me through building out my client acquisition. He showed me how to structure a LinkedIn authority funnel and run cold email alongside it, and since putting it into action I've had a consistent high number of qualified calls booked every month. Highly recommend working with Jun.

Jun has been pivotal to our success in understanding the best positioning and methods to increase our B2B success. Clear, strategic and easily digestible information and also a founder friendly approach. 10/10 service. Thanks again.

Jun helped me a ton with my whole profile, positioning, and content strategy, pretty much everything. Gave me some advice on cold email and helped all around. You got to work with him, absolute G 👍

I recently had a 35-minute strategy session with Hsien Jun, and I was genuinely impressed by both the depth of his knowledge and his generosity. He walked me through a complete and practical approach to LinkedIn growth. Covering organic content strategy, inbound and outbound outreach, lead magnets, post formats, positioning, and how all these elements work together to build a natural and sustainable pipeline. He didn't just share surface level tips, he helped me understand the reasoning behind the strategy and how to apply it in a structured way. I would confidently recommend Hsien Jun Ong to any founder, agency, or B2B professional looking to improve their LinkedIn presence.

Just wrapped up a speed-to-lead qualification voice agent with Jun, and the experience was exceptional. He built an AI voice agent that calls and qualifies leads within 60 seconds, and the execution was flawless. Jun is super fast, extremely detail-oriented, and clearly has a deep understanding of voice AI. If you have anything to do with voice AI, Jun is the guy to go to. It's a complete no-brainer.

I hired Jun to help me build out an outbound AI voice system that could call on my behalf. Jun positively surprised me, both with his professional onboarding, but also delivery practices. He kept everything very clear and easy to understand, so that the finished work would solve my required needs. I've heard the big boys talk about "hiring A-players" — I'm starting to get that quote.

Jun is an absolute rockstar! From setting up the AI agent to integrating it, he even showed us how it all works and everything. Top-notch!

"She's (our AI Receptionist) better than my top dispatcher, as far as explaining stuff. You can actually ask her additional things. What's the tire size? She'll know. How far is that city from LA? She'll tell you. It's pretty cool. I'm 100% satisfied."

Jun did an excellent job as a Voice AI consultant on our project. He was highly knowledgeable, professional, and proactive, with a strong understanding of voice AI systems and real-world implementation.
