Operators who have done the work
We hire people who have run the function they are being asked to run.
Midcore is about 52 people. Every engagement is owned by a US-based practice lead, and our delivery teams are US-based, offshore, or blended depending on what the client approves. We hire people who have run the function they are being asked to run.

Four things that actually hold
These are the same commitments we make to clients. They only work if they run internally too.
Say the hard thing
We tell clients when the problem is upstream of what we were hired for, and when an engagement should shrink. That only works if the same honesty runs internally.
Work in the open
We work inside the client's systems, and every number we report traces to a record they can open. No black boxes, internally or externally.
Own the outcome
Named leads, direct lines, and response-time commitments in writing. Accountability is not distributed until it disappears.
Neutral by construction
We take no referral fees, commissions, or revenue shares from any vendor. Nobody here has a quota tied to a partner's product.
The offer
No vendor quotas, no distributed accountability, and no black boxes. The same commitments we make to clients apply internally.
- Remote-first, with a Pacific-time business core
- A named lead and a real development path in your practice
- Direct client exposure from your first engagement
- No vendor quotas, ever
- Work on payments problems at portfolio scale
- Blended US and global teams
