VS Clearbit

Clearbit Enriches What You Have. FlareSight Finds What You Do Not.

Clearbit fills in firmographic data on companies already in your pipeline. FlareSight surfaces the companies that belong in your pipeline but are not there yet: the ones that filed a Form D with the SEC this week and have not appeared anywhere else.

Why marketing teams add FlareSight before Clearbit in the funnel

Hours
From SEC filing to FlareSight

The companies Clearbit cannot enrich yet

Clearbit enriches companies with a web footprint. A company that filed Form D yesterday may have no website yet. FlareSight surfaces it anyway. The filing is the record.

~90%
Of seed rounds get no top-tier press

Discovery before enrichment

~90% of seed-stage raises receive no top-tier press coverage. Enrichment tools only work after you know the company exists. FlareSight reads the Form D directly so your prospect list includes companies no enrichment tool has touched.

Free
To start, no credit card

Independent of HubSpot stack

Clearbit's capabilities are now bundled into HubSpot. FlareSight is an independent product. Free tier with no credit card. Search newly funded companies today regardless of which CRM you run.

Other Clearbit alternatives

FlareSight is one option. Here is how it sits relative to other tools in the sales intelligence and funding discovery space.

ZoomInfo

B2B contact and company intelligence platform at enterprise scale.

Best for: Large sales and marketing operations teams running high-volume prospecting.

Where they win: Massive contact database, deep firmographic data, intent signals, and tight CRM integrations at enterprise scale.

vs. FlareSight: ZoomInfo requires a custom quote and contract. FlareSight is self-serve with a free tier. For teams who need a funding trigger more than a contact database, FlareSight is the faster entry point.

Apollo.io

Contact database and outbound sequencing platform.

Best for: SDRs and AEs running high-volume outbound campaigns.

Where they win: Self-serve pricing from $49/mo, sequencing built in, large contact database with email and phone.

vs. FlareSight: Apollo surfaces the contact. FlareSight surfaces the trigger: which companies just closed a round and are now in their buying window. The two work best as a stack.

Crunchbase

Global startup and investor database, the legacy standard for funding research.

Best for: Investors, analysts, and researchers tracking global deal flow.

Where they win: Broad global coverage, investor relationship graphs, acquisition tracking, and historical depth.

vs. FlareSight: FlareSight is faster on US funding discovery (hours vs. days) and indexes quiet rounds that Crunchbase never sees.

Harmonic.ai

AI-assisted startup intelligence using signals from GitHub, job boards, and LinkedIn.

Best for: VCs and investors tracking emerging companies before a round closes.

Where they win: Multi-signal approach catches momentum before funding. Good for investors building pre-funding thesis-driven deal flow.

vs. FlareSight: FlareSight gives you a confirmed funding event from a legal filing, not an inferred signal. For sales use cases where certainty matters more than prediction, Form D is the cleaner trigger.

People Data Labs (PDL)

Developer-first contact and company data API.

Best for: Engineering and data teams building custom enrichment pipelines.

Where they win: High-volume, low-cost API access to contact and company data. Strong for building enrichment into internal tools.

vs. FlareSight: PDL enriches records you provide. FlareSight generates a list of records worth enriching in the first place: companies that just closed a US equity round.

How to evaluate a Clearbit alternative

Data enrichment tools and funding discovery tools solve different problems at different stages of the same funnel. Six criteria to consider.

Discovery vs. enrichment
Clearbit is built for enrichment: you give it a domain or email and it returns firmographic data. FlareSight is built for discovery: it gives you a list of companies you did not know existed yet because they filed a Form D this week. These are two different stages of the same funnel. Discovery happens first; enrichment happens after.
Where the list comes from
Enrichment tools including Clearbit, PDL, and ZoomInfo assume you already have a list. The question FlareSight answers first is: which companies should be on that list? If your ICP is "recently funded US startups in SaaS or fintech," FlareSight builds that list from Form D filings. Enrichment tools take over from there.
Timing of the signal
Clearbit enriches companies in real time as records flow through your CRM or marketing automation platform. FlareSight surfaces a point-in-time event: a company closed a round and filed Form D. Both are time-sensitive, but FlareSight's signal has a clear expiration: the buying window closes roughly 30 to 90 days after the round.
HubSpot dependency
Since the HubSpot acquisition, Clearbit's capabilities are increasingly bundled into HubSpot plans. If you run your marketing stack outside HubSpot, access and pricing may change over time. FlareSight is an independent product with its own roadmap, free tier, and published pricing.
Coverage of unannounced rounds
Clearbit enriches companies that have a web presence. A company that filed a Form D yesterday may have no website, no LinkedIn page, and no press coverage yet. It is invisible to enrichment tools. FlareSight picks it up because the Form D is the record, not the press release.
Workflow fit
The clearest workflow: use FlareSight to identify which companies just raised this week, then use Clearbit or a comparable enrichment tool to fill in firmographic and contact details on those companies before routing them to outreach sequences. FlareSight generates the signal; enrichment tools complete the record.

What it looks like in practice

Three specific workflows. What you search, what you get, and what changes relative to Clearbit.

1

Marketing-ops manager building ABM account lists

Task: Identifying newly funded accounts to add to account-based marketing campaigns before they enter vendor evaluation, so the brand is visible before the RFP goes out.

On FlareSight

Pull last month's Form D filings by sector and geography. Export to CSV. Send to enrichment pipeline to fill in firmographics. Upload to LinkedIn Campaign Manager as a matched audience. Ads run before the target company has published a single press release about the round.

On Clearbit

Clearbit enriches companies already in your HubSpot pipeline. It does not surface companies you have not heard of yet. The newly funded accounts that never made the news never enter the Clearbit enrichment flow.

2

SDR identifying inbound leads from funded companies

Task: Cross-referencing inbound leads against recently closed funding rounds to prioritize outreach to accounts with fresh capital.

On FlareSight

Run a daily filter: pull Form D filings from the last 14 days in your target sectors. Cross-reference against your inbound list. Flag accounts where the company filed in the last two weeks. Those contacts get top-of-queue treatment.

On Clearbit

Clearbit can tell you a company's size, industry, and technographics. It surfaces funding data when available from public sources, but the lag means the same window of opportunity is already narrowing by the time the signal reaches your CRM.

3

Account researcher building target lists for a GTM motion

Task: Building a list of 50 to 100 seed-stage fintech companies that raised in the last 90 days, qualified by round size and geography, to feed into a new outbound program.

On FlareSight

Filter by sector: fintech. Round type: seed. Round size: $500K to $5M. Date filed: last 90 days. Export. 50 to 100 matching companies, with filing date, round amount, and company location. Feed into enrichment for contact data.

On Clearbit

Clearbit does not have a search interface for filtering by funding recency. It enriches records you already have. Building the initial list from scratch requires a different tool, then Clearbit layers on top.

Frequently asked questions

Is FlareSight a Clearbit replacement?+
No. Clearbit (now part of HubSpot) is an enrichment tool: it takes companies and contacts you already know about and fills in firmographic details, technographics, and intent signals. FlareSight is a discovery tool: it surfaces companies you would not have found yet because they filed a Form D with the SEC this week. The two solve different problems. Clearbit enriches your existing pipeline; FlareSight builds the top of it.
What happened to Clearbit pricing after the HubSpot acquisition?+
Clearbit was acquired by HubSpot and rebranded as HubSpot's B2B data product. Clearbit.com no longer shows independent pricing tiers. Access to Clearbit's enrichment capabilities is bundled into HubSpot plans. FlareSight is an independent product with a free tier and published pricing starting at $39 per month.
How is FlareSight different from Clearbit's company data?+
Clearbit aggregates company data from public web sources and proprietary databases to enrich records. It is strongest on firmographics for known companies. FlareSight reads SEC Form D filings directly, which means it surfaces newly funded companies hours after the round is legally recorded, including companies with no web presence, no press coverage, and no LinkedIn page worth enriching yet.
Does FlareSight do lead enrichment like Clearbit?+
FlareSight is not an enrichment tool. It surfaces companies from Form D filings with the data available in the filing itself: company name, location, sector, round amount, type, and filing date. Paid plans include founding team contact data. For enrichment of those companies once they are in your pipeline, tools like Clearbit or Apollo are better suited.
What rounds does FlareSight cover?+
FlareSight covers all US equity raises that file SEC Form D, including seed rounds, Series A through later stages, bridge rounds, and SAFEs above the exemption threshold. This includes rounds that never get press coverage. An estimated ~90% of seed-stage raises receive no top-tier press. If a Form D was filed, it is in FlareSight.
Is there a free tier?+
Yes. FlareSight has a free plan with no credit card required. The free tier lets you search and view recently filed companies with basic filing data. Paid plans add contact data, saved searches, and higher result limits.
