From Spreadsheets to a Real Platform | Razoyo
Manual Operations · Spreadsheet to Platform · Proven at Scale
If a Spreadsheet Is Still Running Part of Your Business, the Question Is Not Whether. It Is When.
Spreadsheets stop being enough at a specific point, not when they feel messy. Razoyo has made this exact move at the scale that matters, and the arc is the proof.
More than one person has to touch the same numbers now.
We cannot tell who updated it last, or if it is even current.
This started as one person's process and now the whole team depends on it.
We do not know if this is worth building or if we are overreacting.
When Has a Spreadsheet Actually Stopped Being Enough?
Not when it feels messy. Spreadsheets stop being enough at a specific point: when more than one person has to touch the same numbers and the real, current answer depends on knowing who updated it last. That is the moment reporting stops being reporting and starts being detective work.
The clearest version of this Razoyo has seen: a hotel revenue-management process that started as one property team's manual routine, the same shape of problem as a spreadsheet even though it was not literally one. It could not extend past a handful of properties. Reservation exports are large, and revenue management needs a daily snapshot to compare pace, pickup and same-time-last-year, which meant ingesting every property every morning and snapshotting history on top of it. Ingestion was failing almost daily, and the team could not onboard more properties. In January 2020 Razoyo rebuilt it from the ground up as Spider, on Elixir, Phoenix and Google Cloud managed services. It now runs continuous, terabyte-scale daily processing instead of a 24-hour re-index, serves over 10,000 daily users, and cut hosting costs by roughly 90 percent. The product, Lighthouse, ranked #1 of 74 platforms in Business Intelligence at the 2025 HotelTechAwards and was acquired in 2022. Razoyo is still Spider's engineering team today.
That is the pattern this page is for: a process that started manual, hit a wall nobody solved for it, and became a category leader once the underlying system was rebuilt properly.
Scoping the first version
What a First Version Should Include, and What It Should Not.
The right first version handles the common path well and flags the exceptions for a human, the same way the spreadsheet effectively does today, just faster and without the manual reconciliation step.
Include
- The two or three numbers people actually check today, in the order they check them
- Whatever makes today's routine slow, re-entry, waiting on one person, reconciling sources that disagree
Leave out, on purpose
- Every edge case your spreadsheet has quietly accumulated over years
- One-off exceptions nobody remembers deciding on, rebuilding all of them on day one turns a six-week project into a six-month one
A System Spec or Workflow Spec (the audit and product brief step) tells you, before any build cost is committed, what the first version should include, a senior-engineer estimate, and a plain build or don't-build recommendation. Fixed at $2,500.
The move itself
You Do Not Lose the History, and the Team Does Not Relearn Everything at Once.
Migrating your spreadsheet's history is part of the first phase, not an afterthought.
History migrates with the build
The numbers people already trust stay the same
Exceptions come in a second pass
The team does not have to relearn everything at once.
Frequently Asked Questions
Not necessarily. Some spreadsheet replacements are a focused internal tool; some grow into a product, the way Lighthouse did. The Spec tells you honestly which one you are looking at.
