Built by the people who do the work.
ProjectXL comes from TMS — a project management services company with two decades of delivery on complex programs. We are not a startup that studied project controls from the outside. We are practitioners who have run schedules, managed costs, and delivered status reports under real program pressure.
Where this came from.
For twenty years, TMS has embedded project controls professionals inside large-scale programs — infrastructure, energy, defense, technology. The same pattern appeared on every engagement: the schedule lived in one tool, the cost plan lived in a spreadsheet, and status and forecast happened in yet another set of files that no one fully trusted.
Every new project meant rebuilding the same workarounds. Every new tool adoption meant convincing teams to leave Excel — and watching most of them quietly refuse.
ProjectXL started as an internal question: what if we stopped fighting Excel and instead brought governed scheduling, cost integration, and status logic directly into the workbook?
What practitioner-built means.
Real program experience
The design decisions are informed by years of managing schedules, running status cycles, and reconciling cost data — not by user research surveys alone.
No black-box logic
Every computation in ProjectXL is deterministic and auditable. We built the tool we would trust with our own program data — that means no hidden math and no unexplained results.
Governance by default
Validation, readiness gating, and data integrity rules exist because we have lived with the consequences of not having them. They are not afterthought features.
Excel-native by conviction
We chose Excel because our teams already worked there. This is not a technology bet — it is a recognition that the best adoption strategy is no migration at all.
AI bounded by discipline
The AI layer is advisory only. It cannot modify project data or override the scheduling engine. We built it this way because we have seen what happens when automation operates without guardrails.
Commercial honesty
We are building this product in the open. Pricing, licensing, and capability scope are shared directly — not gated behind sales calls. Beta evaluation is genuine, not a funnel exercise.
What we are building toward.
100% Traceable Data
Every number has a source. Every computed value has an auditable chain. The system does not silently interpolate or approximate.
Zero Black Box Logic
If the engine computes a date, you can trace why. If a cost changes, you can see what drove it. No hidden formulas, no opaque algorithms.
24/7 Live Integrity
Validation runs continuously — not as a batch check. Inconsistencies are flagged as they occur, not discovered in a review meeting.
