Show HN: UeCalc – Build an investor-ready financial model without spreadsheets

[daniilkhanin]

Hey HN, I’ve built ueCalc, a tool that helps startup founders create a financial model in minutes—without needing finance skills or spreadsheets.

The Problem:

Most founders struggle with financial modeling because they:

Don’t know how to create a model or what to include.

Don’t know how to fill it with real data—just assumptions.

Don’t account for experimentation time when testing channels.

Don’t know how to reflect growth—what’s realistic?

Can’t answer investor questions about the numbers.

Investors don’t believe in their projections.

Don’t understand how much funding they really need.

Can’t justify why they need the investment.

How ueCalc solves this:

– Instead of guesswork, you describe your team’s real capabilities:

– Lead acquisition (How many leads can you generate?)

– Conversion (How many turn into customers?)

– Retention (How long do they stay?)

– The system applies unit economics + Goldratt’s Theory of Constraints (Lean Startup) to build an accurate growth forecast.

– You instantly get financial statements & projections—no need for Excel.

What you get:

– A financial model based on execution, not assumptions.

– Revenue, cost, and profitability forecasts.

– Investor-ready financial documents—just download the template.

What’s been your biggest challenge with financial modeling? Let’s discuss!

One thing we noticed while building ueCalc: most founders don’t struggle with spreadsheets—they struggle with knowing what to put in them. Financial models often feel like a black box, and many startups either overestimate their revenue or underestimate their costs. We wanted to change that by focusing on real execution potential. Curious—what’s been your biggest challenge in financial modeling?

[daniilkhanin]

A surprising insight we found: many early-stage startups don’t account for experimentation time in their financial models. They assume a straight growth trajectory, but in reality, optimizing acquisition and conversion takes multiple iterations. With ueCalc, we tried to reflect this by making modeling more adaptive. How do you handle this in your financial planning?

[daniilkhanin]

One of the biggest investor red flags is when a startup can’t clearly explain its numbers. We’ve seen founders tweak financial models to fit investor expectations rather than reality. Instead, we designed ueCalc to help startups justify their projections based on actual team execution capacity. Have you ever had an investor push back on your financial model? What was their concern?

Interesting! How does ueCalc handle early-stage startups where there isn’t much historical data? Do you rely on projections based on execution capacity?

[daniilkhanin → Mihailorama]

Exactly! Instead of relying on historical data, ueCalc focuses on what your team can execute today. You define how you acquire leads, convert customers, and retain them. The model then projects realistic growth based on unit economics and the Theory of Constraints. This makes it especially useful for early-stage startups testing their go-to-market strategy.

it looks really useful! I’ve always struggled with financial modeling because I wasn’t sure what numbers to use. Does ueCalc suggest benchmarks or industry data?

[daniilkhanin → zvezdnii1]

Great question! ueCalc doesn’t provide predefined benchmarks because every startup operates differently. Instead, it helps you structure your financial model based on your team’s real execution capabilities—lead generation, conversion, and retention. This makes the projections much more reliable than generic industry benchmarks.
