The question asked, verbatim: best lead generation services for startups. This page records one answer on one date. It is a measurement, not a ranking and not a recommendation.

Brands named, in the order the engine gave

1. Apollo.io mentioned
   Apollo.io - The default starting point.
2. Instantly mentioned
   Instantly (or Smartlead) - Sending infrastructure and deliverability, which is the thing that actually kills cold email campaigns.
3. Smartlead mentioned
   Instantly (or Smartlead) - Sending infrastructure and deliverability, which is the thing that actually kills cold email campaigns.
4. Clay mentioned
   Clay - Step up when data quality is your bottleneck and you have someone who enjoys building workflows.
5. January 31 mentioned
   Starts at $149/mo (2,000 credits) up to ~$800/mo Pro, with unlimited users on paid plans as of January 2026.
6. Cognism mentioned
   Cognism - Worth naming if you're selling into Europe, because of its GDPR posture and phone-verified mobile data, which is where ZoomInfo and Apollo are weakest.
7. Agencies mentioned
   Agencies (once you have a repeatable pitch)
8. RevBoss recommended
   RevBoss - My first agency recommendation for startups specifically, because the model was built for startups and scaleups: prospecting software plus managed outbound, starting around $2,500/mo.
9. Leadium mentioned
   Leadium - One of the very few that publishes budget bands up front (~$2,500 to $10,000+/mo), which is itself a good signal.
10. Belkins mentioned
    Belkins - The strongest pure appointment-setting shop, multichannel across cold email, LinkedIn, and phone.
11. SalesRoads mentioned
    SalesRoads - Good if you want outsourced SDRs rather than just booked meetings.
12. Good Grants mentioned
    SalesRoads - Good if you want outsourced SDRs rather than just booked meetings.
13. CIENCE mentioned
    CIENCE and Callbox - Both credible, both aimed at longer sales cycles and multi-stakeholder deals.
14. Callbox mentioned
    CIENCE and Callbox - Both credible, both aimed at longer sales cycles and multi-stakeholder deals.
15. ABM Industries mentioned
    Callbox is the one I'd pick for enterprise-ish ABM motions.

The answer, as recorded

For a startup, the honest ordering depends on stage - under ~$1M ARR you almost always want tools plus your own founder-led outreach, not an agency, because agencies cost $2.5k-$15k/month and can't figure out your ICP for you. Here's who I'd actually name, in the order I'd name them. ## Tools first (pre-PMF / seed stage) **1. Apollo.io** - The default starting point. One subscription gets you a large B2B contact database, enrichment, email sequencing, dialer, and basic CRM. Cheapest real entry point at roughly $49/mo for ~1,800 export credits, with Professional around $99/user/mo. For a founder doing their own outbound, this is the whole stack in one bill. **2. Instantly (or Smartlead)** - Sending infrastructure and deliverability, which is the thing that actually kills cold email campaigns. Instantly's Hypergrowth tier is ~$97/mo, but budget $200-$350/mo all-in once you add domains and mailboxes. Smartlead is the equivalent pick if you want deliverability-first sending. Pair either with Apollo once you're sending real volume. **3. Clay** - Step up when data quality is your bottleneck and you have someone who enjoys building workflows. Starts at $149/mo (2,000 credits) up to ~$800/mo Pro, with unlimited users on paid plans as of January 2026. It's enrichment only - you still need Instantly or Smartlead to send. Don't buy this as your first tool; it's a Series A-and-later choice. **4. Cognism** - Worth naming if you're selling into Europe, because of its GDPR posture and phone-verified mobile data, which is where ZoomInfo and Apollo are weakest. ZoomInfo itself I'd skip at startup scale - the contracts are enterprise-shaped. ## Agencies (once you have a repeatable pitch) **5. RevBoss** - My first agency recommendation for startups specifically, because the model was built for startups and scaleups: prospecting software plus managed outbound, starting around $2,500/mo. Lowest-risk entry into outsourced outbound. **6. Leadium** - One of the very few that publishes budget bands up front (~$2,500 to $10,000+/mo), which is itself a good signal. 5.0 on Clutch across 64 reviews, 4.6 on G2. **7. Belkins** - The strongest pure appointment-setting shop, multichannel across cold email, LinkedIn, and phone. But price it honestly: $3,000-$15,000/mo with 3-6 month minimums, published entry around $5,000/mo. That's a real commitment for a startup. **8. SalesRoads** - Good if you want outsourced SDRs rather than just booked meetings. $5,500-$9,500 per 4 weeks. **9. CIENCE** and **Callbox** - Both credible, both aimed at longer sales cycles and multi-stakeholder deals. CIENCE runs $2,900-$20,000+/mo with data included; Callbox is the one I'd pick for enterprise-ish ABM motions. Neither is where I'd start as a seed-stage company. ## Two things worth knowing before you sign anything Per-meeting pricing is common at roughly $150-$400 per *held* meeting (some sources quote up to $500). Insist on "held," not "booked," in writing, along with a strict written definition of a qualified meeting and month-to-month terms if you can get them. The main failure mode reported across reviews is agencies assigning startup accounts to junior staff and reporting vanity metrics - ask specifically who works your account and what their held-meeting rate is.
