The best time to fix your product was before users started leaving.

The second best time is now.

Helping digital product founders fix conversion and retention through strategic design.

Designed features for Glorify β€” a venture-backed app with 25M+ downloads.

Users sign up and disappear. Marketing spend keeps going out, features keep shipping β€” but CAC climbs and retention stays flat.

So you hired someone to fix it. Months of revision rounds, endless feedback loops, and what came back wasn't it.

Now you're further back than when you started. And the issue was never the design β€” no one stopped to ask if you were solving the right problem.

Here's what happens when that changes.πŸ‘‡

Frequently Asked Questions

Do I need to have a brief ready?

No formal brief needed. Just send me a link to your product and a few lines about what's not working β€” that's enough for me to come prepared. We'll figure out the rest on the call.

What happens after the call?

If it's a good fit, I'll send a proposal within 48 hours. If it's not, I'll tell you honestly and point you in the right direction.

Do you work with my type of product?

Mobile apps, SaaS products, consumer apps β€” yes. Both live products that need a redesign and new products being built from scratch. If you're not sure whether your situation fits, the call will make that clear.

What can I expect working with you?

You'll have Slack access, async video updates throughout, and dev-ready files at the end. You'll always know where things stand without having to chase.

How long does it take?

It depends on what we're building. Focused projects can wrap in 6 to 8 weeks. Larger products with more complexity run longer β€” some collaborations span several months with work delivered across milestones. Either way, you'll know the timeline before anything starts.

How much does this cost?

It depends on the scope. Smaller focused projects start from $8,000. Larger engagements are scoped and priced accordingly. The discovery call is where we figure out what you actually need and what that looks like in practice.
