Most SAP transformations fail not because of technology. They fail because no one in the room has done it at scale before.

Mesooo Solutions was founded by Horatiu Istoan, a Global SAP Solutions Architect with 15+ years leading enterprise transformations across healthcare, manufacturing, logistics, and financial services. Having personally architected and governed SAP RISE, BTP, S/4HANA, and Azure landscapes across multiple regions, Horatiu brings practitioner-level depth that pure strategy consultants cannot match.

Headquartered in Brooklyn, New York. Operating globally in English, German, Romanian, and Spanish.

Three ways
we work together

Each engagement is scoped precisely — fixed deliverables, fixed fee, no junior handoff.

01

SAP RISE & S/4HANA Advisory

Independent architecture guidance for companies migrating to SAP RISE or S/4HANA. We assess your landscape, design the right path, and keep you from the costly mistakes that derail most migrations.

  • RISE Readiness Assessment
  • Migration architecture design
  • Vendor selection support
  • Go-live risk review
02

SAP–ITSM Integration Liaison

Bridging the gap between SAP landscapes and ITSM platforms like ServiceNow. We design the governance model, integration architecture, and operating procedures so both systems work together.

  • SAP–ServiceNow integration design
  • Change management workflow mapping
  • ITIL alignment for SAP operations
  • Fractional liaison retainer
03

SAP Landscape Health Audit

A two-week diagnostic uncovering what is actually happening inside your SAP environment: performance gaps, integration risks, upgrade exposure, and cloud readiness. Delivered with a clear action plan.

  • Architecture and performance review
  • Cloud and RISE readiness score
  • Risk and gap report
  • Prioritized remediation roadmap
Why Mesooo

Senior expertise.
No junior handoff.

At the Big 4, you buy a partner's pitch and get a team of analysts. At Mesooo, Horatiu Istoan personally leads every engagement. You get the depth of someone who has built, governed, and transformed SAP landscapes at global scale.

Practitioner, not theorist
With 15+ years of hands-on SAP architecture across global enterprises, everything we advise is grounded in what works in production. Not theory.
Independent and conflict-free
No SAP reseller agreements. No vendor kickbacks. Our recommendations are based on what is right for your landscape, not our margin.
Global reach, boutique accountability
Operating across US, Europe, and APAC in four languages, with the responsiveness of a firm that has your number, not a ticketing system.
MIT Design Thinking trained
We approach architecture problems with a user-centric lens, so solutions actually get adopted by the people who have to use them.

How an engagement works

Four steps. No surprises.

01
Discovery call

20 minutes. We listen to your situation, ask the right questions, and tell you honestly whether we can help, and how.

02
Scoping and proposal

We define the engagement precisely: scope, timeline, deliverables, and fixed fee. No hourly surprises.

03
Hands-on delivery

Horatiu leads the work directly. You get senior-level thinking applied to your specific landscape. Not templated advice.

04
Ongoing partnership

Many clients move to a retainer after the initial engagement. We stay involved as your landscape evolves.

Let's talk about
your SAP
landscape.

Whether you are scoping a RISE migration, struggling with BTP integration, or want an independent second opinion. A 20-minute call costs nothing and usually clarifies everything.
