A Message From Our Founder

What our customers say

We're the #1 face towel on Amazon, but our Shopify offers were too slow and confusing. They rebuilt for speed, fixed our subscription flow, and our online revenue is now growing 18%.

They did more than deliver on time. Their proactive leadership and technical skill in delivering a really complex design from Figma ensured we launched our premium brand in weeks.

One custom app built by EXTFOX replaced five. It manages our discount tiers, runs 40% faster, and saved us $12K a year. We felt the difference!

Next-level communication and skill. They found our site was too confusing, simplified it, added trust, and fixed our conversion rate in a month. We are not burning money on ads anymore.

We needed an MVP to prove our model in 3 weeks, not a year. EXTFOX integrated our legacy portal with new payment systems and built the dashboard from scratch. They worked directly with my dev lead, and we launched in weeks.
