100k+ downloads. €20M raised. Two years embedded. They just extended for another six months.
I told them: try us for a month free. If we're not better, walk away. That was two years ago.

One month free trial. Two years and counting.
They were with an agency that promised everything and delivered slow. We offered a free month: if we're not better, walk away. Two years later, they extended for another six months. Unprompted.

Consistent delivery while their team evolved
Bonanza Studios had a broad range of skills, delivered on their promises, and maintained a great attitude."
Their agency promised everything. Delivered slow.
Ostrom had just raised €20M. 100k+ downloads. Moving fast. Their agency offered unlimited requests per month but delivered slow. When you're scaling, slow is expensive. They needed a partner who ships, not one who promises.

One month to prove it. Two years later, still here.
We didn't write a proposal. We offered a deal: one month free, head-to-head against their current agency. If we're not better, walk away. No cost. No commitment.
Free month against their existing agency. Same requests. Different speed. They saw the difference immediately.
UX design, marketing support, feature work. We became part of the team. Employees changed. We stayed.
No pitch needed. They extended for another six months. Unprompted. That's the only testimonial that matters.
Their team evolved. New hires, departures, reorgs. We kept shipping.
We don't track NPS. We track renewals.
2+ years embedded, 6-month extension unprompted
They didn't renew because of a pitch deck. They renewed because we delivered. Every week. For two years.
