What clients say
Fred was an absolute pleasure to work with on my sports app, Wager Vibes. He built the entire website from scratch and delivered a clean, professional, and fully functional product that looks and runs exactly how I envisioned. His communication was outstanding; he hit every deadline with time to spare.
Derek
Founder, Wager Vibes
Fred took my thoughts of something that I never knew I wanted and turned it into something that I don't know how I was living without. As someone that does part-time creation in full-time chaos, needing a website was never something I thought I needed; but I went to Fred with an idea and he turned it into reality.
Avery
Fred took the time to listen to every detail I wanted added and responded PROMPTLY. He didn't have an issue with any of my changes or additions.
Manny
The Collective
Fred was great and the website he created was better than I even pictured it would be. Thank you Fred, I will definitely work with you again.

23 things to audit on your website before your next fundraise.
Investors check your website before they take the meeting, before they share your deck internally, and again before the partner meeting. This is the checklist I'd run before sending the first warm intro. Bookmark it, it's faster to use than to read.

Your clients' websites are better than yours, and they noticed.
The cobbler's children problem is a meme in the agency world for a reason. Marketing agencies, dev shops, design studios, consultancies, most of them are walking around with a homepage that contradicts everything they're selling. Here's why it happens, what it's costing, and how to actually fix it.

Your website isn't converting because of positioning, not design.
Most founders assume the fix for a low-converting website is a redesign. They rebuild the homepage, swap the colors, redo the hero animation, and the conversion rate barely moves. Here's why, and what to fix first.
