SpreadsheetWeb for startups
Take a spreadsheet prototype from idea to web application.
Founders often prove the hard part of an idea in a spreadsheet: the calculations, assumptions, and business rules. SpreadsheetWeb provides a faster path to a browser experience that real users can explore while the model remains familiar to its creator.

The operating challenge
The prototype exists, but custom development is still a large step.
A working spreadsheet can demonstrate an idea long before a startup has a software team or development budget. Turning that prototype into conventional web software requires technical expertise, creates a new codebase to maintain, and can delay the user feedback needed to validate the concept. Sharing the workbook instead can reveal the model's intellectual property.
Common startup workflows
Put the model in front of users sooner.
Use the spreadsheet as the calculation engine while presenting the idea through a product-like web experience.
Product prototypes
Turn the inputs, rules, and outputs in an Excel prototype into a browser interface suitable for user exploration.
Financial tools
Deliver forecasting, planning, pricing, or feasibility models as a consistent web application.
Customer calculators
Let prospective users receive value from the model without downloading the workbook or seeing its formulas.
Internal operating tools
Move the spreadsheets used to run an early-stage business into shared applications as the team grows.
SpreadsheetWeb capabilities
Keep the idea moving without discarding the prototype.
SpreadsheetWeb uses the workbook as an application model, helping founders deliver and refine an experience without first translating every calculation into a new programming language.
No-code starting point
Build from existing spreadsheet knowledge instead of waiting for a complete conventional software implementation.
Protected formulas
Run calculation logic on the server so users interact with the product rather than the underlying workbook.
Rapid iteration
Update the spreadsheet model and republish the application as assumptions and feedback evolve.
Application and API options
Start with a web application and connect workbook calculations to other product experiences when appropriate.
Startup customer proof
Entrepreneurial Design brought Coffee Break Financials online.
Entrepreneurial Design used SpreadsheetWeb to deliver its financial-planning system as a web-based application without funding a complete custom build from scratch.
“Without SpreadsheetWEB, I would have spent tens of thousands of dollars on development to build the Coffee Break Financials system from scratch. It fits very well into the continuum of web-based application services that allow our users to work from anywhere—the office, at home or on the road.”
