The best owler alternatives
#1Crunchbase
Best for: Investors and teams tracking private companies4.4/5 on
G2 (413 reviews, checked Oct 2026)
Visit crunchbase.com
Starting priceSee website
Free planYes (basic)
Crunchbase is the closest Owler replacement for company research. Its pitch is timing: with 39 billion live private market signals and 30 million verified updates per year, it aims to surface funding rounds, acquisitions, and closures before they become news. Predictive models trained on nearly two decades of data forecast funding, growth, acquisition, IPO, and even closure and layoff risk.
The platform serves investors, go-to-market teams, analysts, and product teams, and its data powers tools like Clay. Pricing is not shown on the homepage, and the richest predictions sit behind paid plans. For anyone whose core question is "what is this private company doing, and what happens next," Crunchbase is the best starting point.
What we like- Deep private company coverage with 39 billion live signals
- Predictive intelligence on funding, growth, acquisitions, IPOs, and closures
- 80M+ users
Watch out for- Pricing is not shown on the homepage
- Full predictive features need a paid plan
- Contact data is thinner than ZoomInfo or Apollo
#2ZoomInfo
Best for: Revenue teams that need contacts plus company data4.5/5 on
G2 (9,130 reviews, checked Oct 2026)
Visit zoominfo.com
Starting priceSee website
Free planYes
ZoomInfo is the go-to-market heavyweight in this list. It combines verified B2B data on 500 million contacts and 100 million companies with a GTM Context Graph that explains why an account is moving, plus AI agents for account research, meeting prep, and deal prioritization. Integrations cover Salesforce, HubSpot, Dynamics, and 120+ other tools.
The pricing model is consumption-based rather than fixed seat tiers, so costs scale with usage, and ZoomInfo Lite offers a permanent free plan with no credit card required. For teams that want company intelligence plus the people to contact, ZoomInfo is the most complete option here.
What we like- Verified data on 500M+ contacts and 100M+ companies
- ZoomInfo Lite is a permanent free plan
- Buying signals and AI account intelligence included
Watch out for- Full platform pricing is credit-based and varies
- Enterprise-grade depth can be more than small teams need
- Some features require the full platform
#3Apollo
Best for: Prospecting and outreach in one system4.7/5 on
G2 (9,847 reviews, checked Oct 2026)
Visit apollo.io
Starting priceSee website
Free planYes
Apollo turns company intelligence into pipeline. Its AI GTM system unifies prospecting, outreach, and dialing in one workspace, with AI agents that research accounts, build lists, write outreach, follow up, and book meetings. Data covers 240 million contacts and 30 million accounts, refreshed over time, with waterfall enrichment to fill gaps.
The platform is open by design, running alongside CRMs and tools teams already use, with compliance support for GDPR, CAN-SPAM, and regional rules. Pricing is not shown on the homepage, so check current plans. For teams that want research and outreach in one place rather than two tools, Apollo is the best fit.
What we like- 240M+ contacts and 30M+ accounts
- AI agents research, write outreach, and book meetings
- 200+ integrations
- Used by 600,000+ companies
Watch out for- Pricing is not shown on the homepage
- Outreach features may be extra for pure research users
- Data depth varies by region
#4Klue
Best for: Dedicated competitive intelligence programs4.7/5 on
G2 (443 reviews, checked Oct 2026)
Visit klue.com
Starting priceSee website
Free planNo
Klue is one of the two dedicated competitive intelligence platforms in this list, built for teams that run compete programs as a discipline rather than a side task. It centralizes competitor research, battlecards, and win-loss insights so product marketing can arm sales with current, accurate positioning against each rival.
One honest flag: the homepage fetch returned a bot-verification check rather than page content, so this listing rests on domain confirmation and Klue's established profile, and it was not retried. Pricing is not shown on the homepage and the platform skews enterprise. For a formal compete program, Klue remains a leading choice alongside Crayon.
What we like- Purpose-built for competitive intelligence workflows
- Battlecards and win-loss analysis for sales teams
- Established player in the CI space
Watch out for- Homepage fetch showed a verification check, so this listing rests on domain confirmation and the product's established profile
- Pricing is not shown
- Enterprise focus
#5Crayon
Best for: Automated tracking of competitor moves4.6/5 on
G2 (385 reviews, checked Oct 2026)
Visit crayon.co
Starting priceSee website
Free planNo
Crayon automates the tedious half of competitive intelligence: watching rivals. Instead of manual searches across many sources, it surfaces real-time, impactful insights automatically, and its Sparks AI feature runs scheduled tracking on competitors' strategic moves, narratives, events, news, social media, and PR. Integrations put that intel in Slack, Teams, and Salesforce, where teams already work.
Customer stories cite win rates rising from 16 percent to 45 percent after activating insights across the business. Pricing is not shown on the homepage, and the platform pays off most for teams with a real compete program. For automated rival tracking with sales-ready delivery, Crayon is the strongest pick.
What we like- Automatically surfaces real-time competitor insights
- Sparks AI feature tracks strategic moves, news, and social
- Integrates with Slack, Teams, and Salesforce
Watch out for- Pricing is not shown on the homepage
- Best value needs a formal compete program
- Smaller company database than Crunchbase or ZoomInfo
#6Similarweb
Best for: Website traffic and digital market intelligence4.4/5 on
G2 (1,236 reviews, checked Oct 2026)
Visit similarweb.com
Starting priceSee website
Free planYes (limited)
Similarweb answers the question Owler cannot: how much attention a company actually gets online. Its data covers 100 million websites, 4 million apps, 235 million product SKUs, and 20 million companies, with 10 years of historical data. Marketing, research, sales, and ecommerce teams use it to benchmark competitors, size markets, track trends, and find prospects ready to buy.
The data is estimated from panels and models, not exact server figures, so treat figures as directional. Pricing is not shown on the homepage, and a limited free version covers basic lookups. For digital benchmarking and market sizing, Similarweb is the essential complement to funding-focused tools.
What we like- Largest digital data repository with 100M+ websites and 20M+ companies
- Traffic, audience, and app data
- Trusted by 200+ Fortune 500 companies
Watch out for- Pricing is not shown on the homepage
- Traffic estimates, not exact figures
- Best for digital benchmarking rather than funding data
#7Semrush
Best for: Search visibility and competitor SEO4.4/5 on
G2 (4,035 reviews, checked Oct 2026)
Visit semrush.com
Starting priceSee website
Free planFree trial
Semrush is the search intelligence pick. Its platform tracks brand visibility from traditional search results to AI answers, with 29 billion keywords, 43 trillion backlinks, and 808 million domain profiles. Teams use it to dissect competitors' keywords, backlinks, rankings, and traffic potential, run technical audits, and now track prompt-level visibility in AI search tools.
Note that Adobe has acquired Semrush, which may affect packaging over time, though the product continues to operate. Pricing is not shown on the homepage, and a free trial covers first use. For teams whose competitive question is "who wins search and AI answers," Semrush is the definitive tool.
What we like- 29 billion keywords and 43 trillion backlinks
- AI visibility tracking for the new search era
- Site audits, content tools, and social management included
Watch out for- Pricing is not shown on the homepage
- SEO depth is overkill for pure company research
- Adobe's acquisition may change packaging over time
#8PitchBook
Best for: Deep private market research and deal data4.5/5 on
G2 (261 reviews, checked Oct 2026)
Visit pitchbook.com
Starting priceSee website
Free planNo
PitchBook is the institutional-grade pick. Its tagline, "if it is out there, it is in PitchBook," reflects its coverage of private capital markets: deals, funds, investors, valuations, and company financials at a depth consumer tools do not attempt. Investment banks, venture firms, and corporate development teams rely on it for diligence and deal sourcing.
The homepage extract was thin, so this listing rests on domain and title confirmation plus the product's established profile. Pricing is not shown and skews institutional, making it overkill for a quick competitor check. For serious private market research, PitchBook is the deepest source in this list.
What we like- Most comprehensive private capital market intelligence
- Detailed deal, fund, and investor data
- Trusted by investment professionals
Watch out for- Homepage extract was thin, so this listing rests on domain and title confirmation
- Pricing is not shown and skews institutional
- Overkill for casual company lookups
How we chose
We compared each tool on company data depth, funding coverage, contact data, competitive tracking, traffic and search intelligence, and pricing transparency. Every homepage above was opened to confirm it loads and belongs to the product, except Klue, whose fetch returned a verification check; that listing rests on domain confirmation and is flagged. Prices are listed as "See website" where the homepage did not display them, rather than guessed figures. Owler itself was excluded as the product being replaced.
What to check before you switch
Start with your core question. Funding and private company tracking points to Crunchbase or PitchBook. Contacts and outreach point to ZoomInfo or Apollo. Formal compete programs point to Klue or Crayon. Traffic and search questions point to Similarweb or Semrush. Most teams need two tools, not one.
Next, check data coverage for your market. Contact depth varies by region, traffic estimates are directional, and private market data is strongest for US venture-backed companies. Use free tiers and trials to test your actual target lists before paying: ZoomInfo Lite, Apollo's free plan, Crunchbase basic search, and Similarweb's limited free version all allow real checks. Finally, confirm compliance needs, since B2B contact data carries GDPR and CCPA obligations that each vendor handles differently.
Frequently asked questions
Is Owler shutting down?
No. Owler remains an operating service. Teams usually look for alternatives because they need deeper funding data, verified contacts, dedicated competitive intelligence, or traffic data that Owler does not provide.
Which alternative is closest to Owler?
Crunchbase is the closest for company profiles and funding news. For the community-driven company tracking Owler is known for, Crunchbase plus Similarweb covers profiles, funding, and traffic together.
What is the best free option?
ZoomInfo Lite is a permanent free plan, Apollo and Crunchbase offer free tiers, and Similarweb offers limited free lookups. For paid depth, check each vendor's pricing page, since most hide prices behind sales conversations.
Do these tools include contact emails?
ZoomInfo and Apollo do, with verified B2B contact data. Crunchbase, Klue, Crayon, Similarweb, Semrush, and PitchBook focus on companies, markets, or competitors rather than individual contacts.
Can I track competitors automatically?
Yes. Klue and Crayon are built for it, with automated tracking, alerts, and battlecards. Crunchbase offers alerts on funding and company events, while Similarweb and Semrush track traffic and search shifts.
How accurate is the data?
Accuracy varies by source. Funding data from Crunchbase and PitchBook is analyst-validated, contact data from ZoomInfo and Apollo is verified and refreshed, and traffic data from Similarweb is modeled estimates. Cross-check critical figures against primary sources before acting on them.
