A founder who actually returns the call.
Interstellar I.S. is led by Marc Shamp — a U.S. veteran who built a payments business helping merchants stop overpaying, then turned the same lens on telecommunications and IT infrastructure.
Interstellar I.S. was founded by Marc Shamp — a U.S. veteran and operator who built a career identifying where business owners are quietly overpaying and engineering ways to fix it.
His first company in the discipline was a payments business. The thesis was simple: most merchants accept the first processor that calls and never look back, and the industry has structured itself to keep things that way. After years building that practice and watching the same dynamic play out in adjacent categories, the next move was obvious — apply the same independent-advisory model to the much larger and much messier world of telecommunications and IT infrastructure.
That's what Interstellar I.S. is. An independent broker, paid by suppliers rather than clients, structurally aligned with helping businesses procure infrastructure honestly and continuously rather than once-and-done.
The veteran-owned status is not a marketing line. It's a discipline. Every engagement is run with the directness, accountability, and follow-through that the service taught.
What we believe
Independence is structural, not aspirational
We are paid by suppliers, not clients. That's the only way to give honest advice across a portfolio.
Lifecycle, not transaction
The signature is the start of the relationship, not the end. We work renewals with the same rigor as initial sourcing.
Direct, not delegated
The principal answers the call. No outsourced sales floor between you and the people accountable.
Right-sized, not maximized
Most stacks are over-licensed. Our first move is often to cut, not add.
Vendor-neutral, fact-driven
We don't have a preferred carrier. We have preferred outcomes. The recommendation reflects the data, not the relationship.
Outcomes over features
What did the call deflection rate change to? What did the bill go down by? What's the actual measured impact? That's what matters.
