The best Bloomberry alternative depends on which part of Bloomberry you are trying to replace. If it is the subscription-event detection with deeper per-vendor history and a fuller lifecycle (trial, switch, renewal, churn), look at MarketSizer. If it is the tech-install snapshot for ad-hoc lookups, look at BuiltWith or Wappalyzer. If it is enterprise technographic depth plus spend estimates, HG Insights is the fit. If it is broader company-event data via API (hiring, funding, exec change), PredictLeads sits in the adjacent slot. For very small target-account lists, homegrown scraping scripts genuinely work. Bloomberry is not weak on any of these axes - each alternative below is stronger than Bloomberry on one specific job and weaker on the others.
What are the best Bloomberry alternatives?
The best Bloomberry alternatives, by primary job to be done:
- Deeper per-vendor subscription lifecycle: MarketSizer.
- Ad-hoc technographic lookups (any site, any time): BuiltWith, Wappalyzer.
- Enterprise technographic breadth + spend estimates: HG Insights.
- Broader company-event feeds (hiring, funding, exec change) via API: PredictLeads.
- DIY at small scale: homegrown scraping scripts.
Bloomberry itself is a real product in the evidence-based signal category - roughly 1,200 tracked products across many technology categories, real-time install and removal detection, well-priced for its coverage. The "alternative" you pick is really the axis where Bloomberry falls short for your specific motion.
When you actually need a Bloomberry alternative
The most common reason teams outgrow Bloomberry is lifecycle depth. Bloomberry is install-focused - it fires when a technology appears on a target-account site and again when it disappears. The distinction between an active trial and a paid installation is thinner, renewal-window timing is not a first-class signal, and churn detection is limited. If your motion depends on trial-window outreach (the fourteen-to-thirty-day window that decides competitive-displacement), MarketSizer’s event granularity is a real upgrade. History cuts the same way: if you need the full sequence of what an account has evaluated, switched from, and renewed over the past several years, the shallower Bloomberry archive stops short.
A different kind of team leaves for breadth rather than depth. Bloomberry is entirely about technographic events, so a motion that also triggers on hiring, funding, executive changes or news mentions is better served by PredictLeads or a similar company-events tool - a different signal category altogether. And some teams simply need the signal where their reps already work: Bloomberry has a Chrome extension and CRM integrations, but if your team lives inside HubSpot, Salesforce, LinkedIn Sales Navigator or Apollo, in-workflow depth matters - MarketSizer’s SignalOps Chrome extension opens its side panel across all four surfaces.
The alternatives in detail
MarketSizer - deeper per-vendor subscription lifecycle
Best known for: the full subscription-lifecycle signal set (trial, switch, renewal, churn, expansion) across 200+ vendors in Customer Support, Live Chat, ITSM and adjacent SaaS categories, with deep subscription history per account.
Where it beats Bloomberry: deeper per-vendor coverage, distinction between trial and paid installation as first-class signal types, renewal-window and churn events, longer historical horizon per account, in-workflow Chrome extension across the tools reps actually use.
Where Bloomberry still wins: product breadth - Bloomberry covers ~1,200 products across many technology categories where MarketSizer covers 200+ vendors deeply. If your ICP straddles categories MarketSizer does not cover, that breadth is a real reason to keep Bloomberry.
Pricing: credit-based from €245 per month on annual billing. Free 500-credit trial.

BuiltWith and Wappalyzer - technographic snapshot
Best known for: per-site lookups showing what technologies any website is running today, plus a historical archive of when a technology first appeared or was removed.
Where they beat Bloomberry: product breadth (BuiltWith covers ~58,000 web technologies, Wappalyzer ~7,400), free lookup tools for ad-hoc use, lower price for teams that only need occasional snapshot data.
Where Bloomberry still wins: event-based alerting - BuiltWith and Wappalyzer are snapshot tools that show current state, not detection tools that fire when state changes. If you need an ongoing signal feed rather than an on-demand lookup, Bloomberry does more.
Pricing: BuiltWith from $295 per month; Wappalyzer has a free Chrome extension plus paid tiers priced on lookup volume.

HG Insights - enterprise technographic + spend
Best known for: a broad enterprise data-fabric covering roughly 22,000 technologies plus IT-spend and contract-value estimates, sold to strategy, market-intelligence and enterprise ABM teams.
Where it beats Bloomberry: enterprise data depth, spend and contract estimates, analyst-friendly reporting, alignment with enterprise procurement processes.
Where Bloomberry still wins: real-time event detection (HG’s signal shape is aggregated and planning-oriented rather than event-driven), self-serve entry price (HG’s enterprise packages start in the tens of thousands per year).
Best for: enterprise teams whose primary use case is territory design and TAM sizing rather than day-to-day rep prioritisation.

PredictLeads - company-events API
Best known for: a company-events API that surfaces business events (hiring, funding, product launches, expansions, executive changes) as structured signals for GTM teams.
Where it beats Bloomberry: broader event categories (hiring, funding, exec change - not just tech installs), API-first delivery for teams building custom signal workflows, global coverage across companies of all sizes.
Where Bloomberry still wins: tech-stack event depth - PredictLeads is not primarily a technographic tool, so its coverage of tech-install and removal events is thinner than a specialist evidence-based signal platform.
Best for: data and RevOps teams that want raw event feeds via API to plug into their own scoring or enrichment logic. Complementary to Bloomberry rather than a direct replacement.
Full comparison: MarketSizer vs PredictLeads.
Homegrown scripts - the DIY option
Best known for: an internal RevOps or engineering team writes a small scraper that checks a defined target-account list for specific technographic signatures on a schedule.
Where it beats Bloomberry: zero recurring cost, full control over which vendors to track and how signals are shaped, works fine at very small scale.
Where Bloomberry still wins: maintenance overhead. Vendor signatures change (new SDK versions, subdomain migrations, redirects) and homegrown scripts break silently. Coverage across dozens of competitors requires ongoing signature maintenance that becomes a distraction.
Best for: engineering-heavy teams with fewer than 100 target accounts and a handful of tracked competitors, testing whether the signal category matters to their motion before buying a platform. Most teams that build this outgrow it within 6-12 months. See how to detect competitor trials for the mechanics of doing this well.
How to choose
Work through these in order.
- Which specific event granularity matters? If you need to distinguish trial from paid install and to fire on renewal windows and churn, MarketSizer’s event depth is a real upgrade over Bloomberry. If you only need "installed X" and "removed X" events across a broad product surface, Bloomberry itself is a good fit and the alternative is really a matter of breadth vs depth.
- What is your ICP’s software category shape? If your ICP concentrates in Customer Support, Live Chat, ITSM or adjacent SaaS, MarketSizer’s deep per-vendor coverage matters. If it spans many product categories including web tech, ad tech and e-commerce infrastructure, Bloomberry’s breadth or BuiltWith’s technographic footprint fits better.
- Where does the signal need to fire? Chrome extension inside HubSpot, Salesforce, LinkedIn and Apollo - MarketSizer. Standalone dashboard or CSV workflow - Bloomberry. API into a custom pipeline - PredictLeads. Ad-hoc lookup - BuiltWith or Wappalyzer.
