Which team should choose which
Choose Bloomberry if
- Your trigger of choice is a product being adopted or dropped, across any category you sell into.
- You want broad product coverage across many technology categories, not deep coverage in one.
- A focused subscribe/churn feed is all your workflow needs - no scoring layer on top.
Choose MarketSizer if
- You need trial and renewal-window signals as first-class events, alongside subscribe and churn.
- You want signals combined with ICP fit and win-likelihood in one Opportunity Score, not a raw signal feed.
- Category depth matters more than product breadth - deep subscription history per account in the categories we cover.
- You want signals surfaced alongside HubSpot, Salesforce, LinkedIn and Apollo, not in a separate lookup tool.

MarketSizer vs Bloomberry - frequently asked questions
How is Bloomberry different from BuiltWith?
Both track tech-stack signals, but Bloomberry is event-focused (detects installs and removals as they happen) where BuiltWith is snapshot-focused (a current view of what any site is running). Bloomberry is the closer conceptual comparison to MarketSizer inside the evidence-based signal category.
Does Bloomberry detect trials the way MarketSizer does?
Bloomberry detects subscribe and churn events in real time. Whether it separates a paid subscription from a short trial is not documented publicly. MarketSizer treats trial state and renewal windows as first-class signals with their own alerts.
Can Bloomberry and MarketSizer be used together?
They can, though the overlap is meaningful - both live in the evidence-based signal category. Teams sometimes keep Bloomberry for broad install-signal coverage across many product categories and use MarketSizer for deep subscription-lifecycle signals in the categories where MarketSizer has full-history coverage.

Bloomberry does not publish pricing on its site - contact them for a quote. MarketSizer is credit-based (see current plans), with no per-seat multiplier.
