ARR & MRR
Also known as: Annual Recurring Revenue, Monthly Recurring Revenue
The normalized run-rate of subscription revenue — the metric SaaS companies are valued on, and the number competitors most want you to overestimate.
Definition
MRR is the normalized monthly value of all active subscriptions; ARR is the same quantity annualized. As run-rate measures they answer "at current contracts, what does a year of revenue look like?" — which makes them the standard scoreboard for subscription businesses and the denominator of most SaaS efficiency metrics. Neither is a GAAP figure: definitions vary, and what one company counts as ARR (multi-year deals? usage? services?) another excludes.
The composition matters more than the level. ARR growing from new logos means something different from ARR growing from price increases on a shrinking base; net revenue retention above 100% means the installed base grows by itself. These decompositions are exactly what private companies do not disclose.
Competitively, claimed ARR figures deserve skepticism: they surface selectively (companies announce round numbers at fundraises and go quiet otherwise), age badly, and travel through press with definitions stripped. Cross-checking a rival's revenue claims against observable proxies — headcount trajectory, hiring, pricing moves, customer-count claims over time — is the practical verification available from outside.
Why it matters for competitive intelligence
A rival's revenue trajectory shapes their behaviour — pricing aggression, hiring, fundraising — but their announced numbers are marketing. Observable signals are how you sanity-check the story.
How Rivalize helps
Rivalize tracks the public proxies that correlate with revenue trajectory — hiring, pricing moves, funding, traction signals — and cites each, so your read on a private rival's momentum rests on evidence rather than their press releases.

Funding Rounds
The staged venture financings — pre-seed through late-stage — that fund private competitors, and one of the loudest public signals of their intent and clock.
Churn Rate
The rate at which customers (or revenue) leave over a period — the leak in the bucket that caps growth and signals competitive or product pressure.
Unit Economics
The profit and loss of a single unit of the business — one customer, one order, one seat — which determines whether scale will save a company or bury it.
Rule of 40
The SaaS health heuristic that revenue growth rate plus profit margin should exceed 40% — a one-number test of whether growth is worth its cost.

Prompts guess. Rivalize knows.
15-25% of teams use AI prompts for competitive research. Here is why that approach falls short.
Real scraping, not hallucination
We scrape 40+ actual pages per competitor. AI prompts guess from training data that may be months or years out of date.
Source attribution on every claim
Every data point links to where we found it. Prompts cannot cite sources because they do not access real-time data.
Monitoring, not one-shots
Rivalize tracks changes over time and scores momentum trends. Prompts give you a snapshot that is already stale by the time you read it.
