VS Clearbit
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.
They are not the same type of tool. Here is where they differ on the dimensions that matter for sales prospecting and account targeting.
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-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.
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.
FlareSight is one option. Here is how it sits relative to other tools in the sales intelligence and funding discovery space.
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.
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.
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.
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.
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.
Data enrichment tools and funding discovery tools solve different problems at different stages of the same funnel. Six criteria to consider.

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