The Best Free Startup Databases for Sales Prospecting in 2026

A database and a signal are not the same thing

Most lists of "startup databases" conflate two different needs. A database tells you a company exists and gives you profile data. A signal tells you something just changed at that company, right now, that makes them worth calling.

For outbound, you need both. The database tells you whether the company fits your ICP. The signal tells you when to reach out. Reaching out with good data but bad timing is just cold email. Reaching out with good timing and no data is a spray-and-pray sequence. The combination is what produces pipeline.

Every tool below does one or both of these things. Knowing which is which helps you stop looking for one tool that does everything.

1. SEC EDGAR (free) and FlareSight free tier (5 profiles/day)

EDGAR is the SEC's public database of company filings. When a US startup raises money, it files a Form D within 15 days of the first close. That filing is public, free to access, and pre-dates any press coverage. It includes company name, state, industry code, total raise, type of security, and the names of executives who signed.

Raw EDGAR is a timing signal, not an enriched database. You get a company name and a funding event. You do not get a website, a description, a headcount, or founder contacts. To turn a Form D into a workable prospect, you cross-reference manually: search the name, find the website, find the founder on LinkedIn, verify the industry fit. That sequence runs 15 to 25 minutes per company.

FlareSight indexes Form D filings daily, enriches each one with website, description, and employee count, and surfaces the results in a searchable interface. The free tier gives you 5 company profile views per day. That is not enough for a full prospecting session, but it is enough to validate whether the database fits your ICP before committing to a paid plan.

Best for: timing. The only pre-announcement funding signal available for free. Use this first to identify the window, then enrich elsewhere.

Limits: funded companies only. No contact data on the free tier. 5 profile views per day on FlareSight. Raw EDGAR requires manual enrichment.

2. Crunchbase free tier

Crunchbase has the deepest company profiles in the free startup database space. Funding rounds, investor names, founding date, headcount ranges, acquisitions, and in many cases a short company description written by the Crunchbase editorial team. For research on a specific company, it is the first place to check.

The limitation for outbound prospecting is timing. Crunchbase data lags press coverage by 7 to 14 days on average. It also lags EDGAR. By the time a round appears in Crunchbase, the announcement has already run, every Google alert has fired, and the founder's inbox has a full week of "congrats on the raise" sequences from other SDRs.

The free tier limits search to a small number of results per month. You cannot build a list of companies filtered by funding date, size, and industry without hitting the wall quickly. For single-company research it is fine. For volume prospecting it is not.

Best for: depth on a specific company you already identified. Pre-call research.

Limits: search volume capped on free tier. Data lags by 7 to 14 days. Not a timing signal.

3. LinkedIn

LinkedIn is the best source of contact data and org charts. For any company you identify through another tool, LinkedIn tells you who is in what role, how long they have been there, and who the relevant buyer is for your category. Nothing replaces it for that.

LinkedIn is not a funding signal. "News" posts about funding rounds appear 5 to 12 days after the announcement, which is already 2 to 4 weeks after the Form D was filed. For serious outbound prospecting at volume, LinkedIn Sales Navigator starts at $99 per month. The free tier has no saved search alerts and no reliable way to surface newly funded companies.

Best for: contact data, title verification, org chart mapping after you have identified the company.

Limits: no funding timing signal. Sales Navigator required for volume prospecting ($99/month). News alerts lag by 5 to 12 days.

4. AngelList / Wellfound

Wellfound (formerly AngelList Talent) has a solid database of early-stage companies, particularly those that raised small rounds from angels or micro-VCs. Many founders list their companies there because it connects them to candidates and investors.

Coverage is self-selected. Only companies that opted in to list themselves appear. That excludes a large fraction of Form D filers, particularly those raising from institutional funds who do not need the recruitment-oriented exposure Wellfound provides. For pre-seed and seed-stage companies in consumer-facing or venture-backed sectors, the coverage is reasonable. For companies raising $5M-plus from institutional investors, it is incomplete.

Best for: early-stage companies, particularly those hiring aggressively. Founder contact discovery for pre-seed.

Limits: self-listed only. Not comprehensive. No funding timing signal.

5. Product Hunt

Product Hunt surfaces newly launched products, not newly funded companies. The two categories overlap but they are not the same. A company can launch on Product Hunt at any point in its life, funded or not. A company can raise a round without ever touching Product Hunt.

The database is useful for finding companies at launch moment: the day they are most likely to be responsive to outreach, generating press, and actively evaluating new tools. That is a real buying signal. It is just not a funding signal.

Product Hunt skews B2C, developer tools, and productivity apps. If you sell to enterprises or into verticals like healthcare, finance, or logistics, the coverage is thin.

Best for: B2C and developer-tool companies at launch. Finding early adopters of new categories.

Limits: not funding-specific. Biased toward consumer and dev tools. No search volume restrictions on free, but coverage is incomplete.

6. Apollo.io free tier

Apollo is a contact database, not a company discovery tool. It does not surface companies based on funding events. You use it after you have a company name: search for contacts at that company, filter by title, and get an email and phone number. The free tier allows 50 contact exports per month.

The database has broad coverage, particularly for US companies with 10-plus employees. Data quality on email addresses is decent. For enriching a list you already built from another source, it is a practical free option up to 50 records per month.

Best for: contact enrichment after company identification. Email and phone lookup by title.

Limits: 50 exports per month on free tier. No funding signal. Requires knowing the company first.

7. Google Alerts

Google Alerts sends an email when new indexed content matches a keyword. Set an alert for "raised Series A" or "announces funding" and you get a daily digest of press coverage.

The problems are noise and delay. Alerts fire on press releases, which are written after the round closes, edited by PR firms, distributed through wire services, and indexed days later. You are at the end of a long chain. You also get false positives from opinion pieces, retrospectives, and international coverage of companies outside your market.

Alerts miss any company that did not issue a press release, which is a large fraction of Form D filers. Smaller rounds, stealth companies, and companies that skip the press cycle entirely are invisible to Google Alerts.

Best for: passively monitoring a specific named company or topic. Not for prospecting.

Limits: press-dependent. Delayed. High noise. Misses any company without press coverage.

Summary comparison

How to combine them

No single free tool covers the full workflow. The practical stack for funded-startup prospecting is three tools in sequence.

1. EDGAR or FlareSight for the timing signal. Check Form D filings from the last 7 to 30 days. Filter by raise size and industry. This gives you a list of companies that just funded and have not yet announced publicly. FlareSight does the filtering and enrichment in the interface. EDGAR requires manual work.
2. Apollo.io for contact enrichment. Take the company names from step one. Look up the relevant buyer by title in Apollo. Export up to 50 contacts per month on the free tier. This gives you an email address without a LinkedIn Sales Navigator subscription.
3. LinkedIn for org chart confirmation. Verify the title and tenure of your contact before sending. Check for recent hires in relevant departments, which signal active vendor evaluation. Do this manually on the free tier; it takes 2 to 3 minutes per company.

Crunchbase fits between steps one and two if you need background on the company before writing your outreach. Google Alerts and Product Hunt are situational, not part of a repeatable prospecting workflow.

What free actually costs

Free tools shift cost from dollars to time. The EDGAR-only workflow, done manually, runs 3 to 4 hours per week to produce a clean list of 10 to 15 ICP-fit companies with enough enrichment to write personalized outreach. That is before you write a single email.

The FlareSight free tier cuts the list-building step to roughly 20 minutes per day, limited to 5 profiles. At 5 profiles per day, 5 days per week, that is 25 enriched, recently-funded companies per week. For a solo founder doing outbound or an SDR running a focused vertical, that is a workable volume at zero cost.

Apollo's 50-export limit on the free tier is a ceiling at roughly 10 to 12 sequences per month if you add 4 to 5 contacts per company. LinkedIn manual lookup adds another 2 minutes per company. The full free-tier workflow, optimized, takes about 30 minutes per day and produces a list of companies that nobody else in your market has reached yet.

That is the honest accounting. The tools are free. The hours are not.
