Deltologic

Big Fly successfully migrated from Amazon MWS to SP-API — without breaking their operations.

In this case, Dennis Oland (Senior Logistics & Ops Manager at Big Fly) shares how we helped them:
• migrate from legacy MWS to Amazon SP-API
• move from the old Inbound Shipments API to the new one
• keep internal systems running under tight Amazon deadlines
• maintain and improve existing solutions

👉 If you’re dealing with Amazon API changes or system migrations, let’s talk.

Last week, Kris Krokos and Jakob Wolitzki flew to Las Vegas for Prosper Show with one goal:
> Validate DataDoe.

We:
- Showcased DataDoe for the first time
- Collected 100+ early access signups
- Got insane feedback like:
“I was planning to build this for myself… can’t believe it already exists.”

The feedback was 🔥.
And the energy? Wild.

Here’s how we approached it:
1. Soft launch, not hard sell.
We didn’t pitch. We showed the product. Let people play with it.
> Result: curiosity turned into commitment.

2. Real conversations over business cards.
We didn’t chase leads. We listened. What people loved. What they’d improve. What they really want.
> We left with a feature list 3 pages long.

3. One ask: early access
No upsell. No payment. Just: “If you want this, sign up.”
> 100+ did...

Now we’re back at Deltologic | Software for Marketplace Sellers, building like crazy.
- We’re still in closed alpha
- Waitlist is open: DataDoe.com
- Next version drops soon

If you run an Amazon agency, manage brands, or build ecom tools — this is something you’ll want early access to 👀

This is just the start.
