Tnuki vs Apollo

One chat replaces the filter sidebar

Tnuki reads 40+ scientific and regulatory databases and turns one chat into a daily list of biotech and pharma prospects worth emailing — verified contact, real trigger, draft ready. Apollo gives you a generic database and 25+ filter clicks.

Plain English instead of filter wizards. Type "find me oncology biotechs that just posted a Phase II readout" — that's it.
1,000+ buying-signal sources, monitored 24/7. Funding, hires, leadership moves, SEC filings — all included.
Real-time discovery, not a static (often outdated) database. Tnuki finds contacts as the web updates them.
Free to use. No credit card or signup required. Apollo's free tier caps at 10K credits and 5 AI chats per year before requiring a paid plan.
Drafts grounded in the trigger. Each row comes with an email written around the buying moment.

In short

What each tool is

Apollo is the most popular sales prospecting tool of the last decade — a 275M+ contact database wrapped in filter wizards and outbound tooling. It's built for teams with an SDR motion and a buyer who already knows the rough shape of their ICP. Its database is broad on firmographics but blind to the science — pipeline stage, trial phase, readouts, KOLs — that life sciences deals turn on.

Tnuki is the AI-first sales intelligence platform built for life sciences. Describe what you need in plain English and five AI agents read 40+ scientific and regulatory databases, monitor clinical and funding signals, verify contacts, and draft personalized outreach. Built for biotech and pharma sales, BD, and commercial teams who don't have time to learn a filter wizard.

The same task, in both tools.

Task: Find 25 biotechs that posted a Phase II readout in the last 90 days. Get verified work emails for the VP of Clinical Development or Head of BD. Draft outreach grounded in the trial result.

Apollo

Roughly 5 minutes: 25+ clicks across 4 filter sections and then learning Apollo's email template syntax.

Capability	Apollo	Tnuki	What this means
Signal monitoring (intent layer)	Apollo Intent (paid add-on) — anonymous web-browsing scores, limited signal categories	Built-in. 1,000+ sources, 24/7 — clinical readouts, FDA actions, biotech funding, exec and KOL moves, AACR/ASCO talks. Source-linked.	Tnuki is signal-first by design; Apollo's intent is a bolt-on with the standard intent-data trade-offs (anonymous, hard to verify)
Setup time	Free trial signup + onboarding (~10 min)	None — no signup, no credit card	Tnuki returns prospects before Apollo's onboarding finishes
Prospecting UI	65+ filter dropdowns	Plain English chat	Apollo's filters are powerful for SQL-like queries; Tnuki's chat is faster for one-off tasks
Contact discovery	275M+ static records	Real-time web search + multi-provider waterfall	Tnuki's data updates as the web does, often surfacing contacts missed by Apollo's static snapshot
Email verification	Built-in scoring	Multi-provider verification waterfall	Cross-checks across providers — higher delivery rate than any single source
Buying signals	Job changes + paid intent add-on	1,000+ sources, all included	Tnuki: signals are first-class, not an add-on
AI personalization	Capped at 5 AI chats/year on free; included on paid plans (intro pricing)	Drafting agent included free	Tnuki drafts grounded in the actual buying trigger
Recurring intelligence	Manual list refreshes	Daily brief delivered to inbox	Tnuki: passive overnight monitoring
Free tier	10,000 credits/year, 5 AI chats/year	Access for free	Tnuki: more powerful free tier
Learning curve	Apollo Academy, hours of training	None — chat is self-teaching	Tnuki: zero curriculum

Choose Apollo if…

You need a built-in dialer for cold-call motions
You need bulk CRM enrichment via API or scheduled CSV jobs at scale
Native HubSpot/Salesforce CRM sync is non-negotiable today
You're already deeply trained on Apollo and switching would create friction

Choose Tnuki if…

You want prospects in under 60 seconds without learning filter dropdowns
You're a life sciences commercial lead, an SDR selling into biotech and pharma, or a seed-stage tools/CRO founder who can't justify a five-figure annual contract
Trigger-based 1:1 outreach is your motion
You want signals as a first-class capability, not a paid add-on

Is Tnuki actually free, or is there a catch?

Tnuki is free at usable limits — full access to chat and recurring Intelligence Briefs. No signup, no credit card. Paid tiers (higher volume, daily briefs) launch in 2026 with public pricing.

Can Tnuki replace Apollo for me?

For most teams running trigger-based outreach: yes. Tnuki replaces the prospecting, enrichment, and personalization layers Apollo provides. Multi-step sequencing is on Tnuki's 2026 roadmap — until it ships, you can pair Tnuki's daily brief with your sequencing tool of choice (Apollo, Outreach, Salesloft) for cadence delivery.

Does Tnuki have as many contacts as Apollo?

Apollo has a 275M+ static contact database. Tnuki's contact discovery is real-time — we search the web as you ask, and waterfall across multiple verification providers — so Tnuki often finds contacts that don't yet exist in Apollo's snapshot, including newly-hired roles, recent moves, and emerging companies. For bulk batch enrichment of 100k+ CRM records at once, Apollo's static API is faster.

Does Tnuki integrate with Salesforce or HubSpot?

Not natively yet — current options are CSV export and Zapier. Native CRM sync is on the 2026 roadmap.

How is Tnuki different from Apollo's AI features?

Apollo's AI is built around their database (writing assistant, sequence personalization). Tnuki's AI is the entire product — five agents (Intelligence, Signal, Contact/Waterfall, Drafting, Concierge) running in parallel. Tnuki's drafts are grounded in the actual buying trigger; Apollo's tend to ground in firmographic data.

Can I use both Apollo and Tnuki together?

Yes. Common pattern: Tnuki for the morning Plays (priority accounts with drafts), Apollo for the high-volume sequence delivery layer.

What about data privacy and GDPR?

Tnuki retrieves only public information (LinkedIn, company sites, news, regulatory filings) via licensed APIs. No scraped private data, no purchased lists. Contact verification happens through GDPR-compliant providers.

Why would I switch from Apollo to Tnuki?

Three reasons: (1) Tnuki gives you full agent access at no cost; Apollo's free tier caps at 10K credits and 5 AI chats per year before you're on a paid plan, (2) Tnuki returns prospects in under 60 seconds vs Apollo's filter-wizard learning curve, (3) Tnuki's signals are first-class — funding, hiring, leadership moves, SEC filings — where Apollo treats deeper intent topics as tier-gated add-ons.
