For founders

Test your startup thesis against the evidence

A business case is built from market reports, customer interviews, what competitors say about themselves, and your own judgement. Some of it conflicts. Much of it is thin. Some of it is one blog post from three years ago that everyone repeats.

What Arbiter does with a thesis

You list the claims your case rests on and the source behind each one. Arbiter weighs every source by type and age, and returns a verdict per claim.

Gaps show up. You see which parts of the argument have evidence behind them and which have none.
Repetition can count once. Ten articles that repeat one press release are one source repeated, not ten sources agreeing. Mark each article as dependent on the press release and Arbiter counts their agreement once. Unmarked, it treats them as ten independent sources, so the marking matters.
Self-interested sources start low. A company's claims about its own product start in the Vendor band, well below an independent researcher. The bands are published in the source-reliability table.

Each investigation keeps the full reasoning, so the case you take to investors or to your board is one you can walk back, claim by claim, to who said what.

What it will not do

Arbiter does not research your market for you and does not know whether your sources are true. We measure the sources you give us against what they say. It tells you how strong your evidence is, not whether the business will work.
