Marketplace Berlin 5 months

Rebuilt a stuck two-sided marketplace — supply onboarding time dropped 91%

A regional services marketplace was bleeding supply because onboarding took two weeks and the booking flow had eight steps. We rebuilt the seller pipeline and consumer booking in 5 months — without taking the live product down.

Client identity withheld. All figures, timelines, and tactics are from a real engagement.

The numbers

What changed in 5 months.

Supply onboarding time

Before: 13.4 days→After: 1.2 days

Mobile booking conversion

+4.3x

Before: 4.1%→After: 17.8%

Monthly GMV

The challenge

What they were up against.

1
Two-week supply onboarding was killing acquisition — 60% of sellers never finished
2
Booking flow had 8 screens; mobile conversion was 4%
3
Tech debt was so deep the prior team refused to ship anything net-new
4
Live product couldn't take downtime — GMV was still growing 12% month-over-month

The work

How we shipped their product.

Step 01

Strangler-fig rebuild

Stood up a new Next.js front-end behind the same domain and migrated routes one at a time. Old monolith stayed live until the last route flipped.

Step 02

Seller onboarding in 4 steps

Replaced the 14-step intake with a 4-step flow plus Stripe Connect identity verification — most sellers finish in under 15 minutes now.

Step 03

Mobile-first booking

Collapsed 8 booking screens to 3 with smart defaults and saved-state. Mobile conversion rate quadrupled in the first month after rollout.

Step 04

Observability before features

Wired in OpenTelemetry, error budgets, and a real on-call rotation. Engineering team started shipping daily by month three.

The outcome

What it meant for the business.

Zero downtime through a full front-end and onboarding rebuild
Supply grew 3.1× in the 90 days after the new onboarding shipped
Internal engineering team adopted the new stack and now ships independently
Marketplace closed a Series B priced on the post-rebuild numbers

"Envert rebuilt our marketplace under us while it was flying. The new product is faster, cleaner, and the team we have today actually wants to ship on it."
