A company in build, five instruments that run in this page, and the repositories behind them.
Co-founding a platform for people who build things together. In build with a small team; third place at the Boğaziçi Enterprize competition. More here as it ships. no promises ahead of the product.
Reimplemented in JavaScript from my Python repositories, running entirely in this page. The inputs are illustrative; the arithmetic is the same as the repositories, and the Python versions carry the tests.
How much of this valuation is the five years that were forecast, and how much is the perpetuity bolted on after them?
Every slider is an argument: growth is the story, the discount rate is the doubt, and the terminal value is where valuations hide.
At a given carbon price, which of these ten measures is worth doing, and what does the set cost?
Bar width is annual abatement. Bar height is the levelised cost per tonne. Select a bar for its arithmetic.
Emissions moved between two years. How much of that was output, how much was the product mix, how much was energy intensity, and how much was the emission factor?
Does this conversion have an answer, and if it does not, what exactly is missing?

The two sizings disagree. Which assumption would have to change, and what would it have to become?
A universe narrowed by factors.
Segments, each a product of drivers.
| Assumption | Now | Implied | Multiple |

Everything public, everything sourced. The instruments above come from the first five; the rest package working method as reusable skills.
Carbon decomposition, target pathways, abatement cost, CBAM embedded emissions.
Market sizing from two directions, DCF with the terminal value taken apart.
Unit and dimension safety for energy and emissions arithmetic. Refuses to guess.
One interface over public climate data; every value carries source, version, date.
Two papers on market predictability, with the models that test them.
Twelve repositories of working method packaged as Claude skills. finance, sustainability, research, writing, risk, and the conventions they share.
