Help auditing Excel models, building with AI, generating LBO cashflows, billing, and support for LBOstack.
New to LBO mechanics? See the LBO model glossary.
How do I get started with LBOstack?
Do I need Excel to build or audit a financial model?
You will need Microsoft Excel for most investment-style models (older versions often work, though some newer functions may differ). Google Sheets is similar but has nuances. Excel remains the default in investment banking and funds management.
LibreOffice is a capable open-source option if you cannot use Excel.
What skill level do I need to use LBOstack?
You should already know spreadsheet fundamentals and LBO mechanics. LBOstack helps with upload, audit, AI-assisted build, and cashflow generation—but you remain responsible for conclusions and sound judgement in deal team review and lender materials.
You should understand corporate finance and LBO mechanics. See the Financial Models page for how audit, build, and cashflow generation fit together.
What payment methods are accepted?
We accept most credit and debit cards through Stripe (our payments processor). If Stripe declines a charge or your region is restricted, contact us and we will try to suggest an alternative where possible.
The app did not load or my upload failed
Try a hard refresh, another browser, and a stable network. Very large workbooks can time out—test with a smaller excerpt if you can.
If the problem continues, send a support request with what you clicked, your browser, and (if relevant) the approximate file size.
What if I want a refund or to cancel?
See our Terms of Use for subscription and refund rules. If you have already consumed paid features, refunds may be limited.
If you have a specific situation, open a support request and we will take a look.
A number or label in my model review looks wrong
If something in the review looks off, send a support request with the cell or sheet reference and what you expected. We will triage whether it is a model issue or a product interpretation edge case.
Do you offer consulting or custom model work?
We can scope short consulting blocks or longer retainers depending on the work. Send objectives, timeline constraints, and what you already have in Excel via Contact.
We will reply with questions and an estimate where there is a fit.
Can you do consulting work for equity in my startup?
Generally we work on a fee basis. Equity swaps are rare unless you can demonstrate strong traction, a differentiated plan, and a credible fundraising path—still no guarantee of fit.
Can you help me raise capital or promote my startup?
We can help tighten models, outputs, and deal team review and lender materials you use in your own process.
We do not market your company to investors on your behalf. Meeting support as an experienced advisor may be possible under a written engagement.
