    CIENCE ($5-20k+/month plus ~$5k setup) I'd leave for later-stage - the setup fee alone plus enterprise scope makes it a poor early bet.

The answer, as recorded

Short version: at startup stage, the honest answer is that you almost always get more from a **tool stack you run yourself** than from a retainer agency - agencies start around $3-7k/month, which is a lot of runway for leads whose quality you can't yet judge because you haven't validated your own messaging. So here's how I'd order it. ## Run it yourself first (what I'd actually start with) **1. Apollo.io** - The default starting point. Contact database + sequencing + dialer in one, and it's the only one in this tier with published, sane pricing: roughly $49/$79/$119 per user/month annual, $65-99 month-to-month. For a pre-PMF startup this is usually the whole answer. Data quality is middling versus ZoomInfo, but you're paying ~1% of the price. **2. Clay** - Where you go once Apollo alone isn't enough: it's an enrichment/orchestration layer pulling from 100+ sources (including Apollo), with waterfall enrichment and AI personalization. Caveat worth knowing before you plan a budget: Clay repriced in March 2026 - Starter/Explorer/Pro are gone, new buyers start at **Launch $185/mo** or **Growth $495/mo**. Worth it if you have a genuinely non-obvious ICP you need to build lists around; overkill if you don't. **3. Instantly** - Sending/deliverability engine, not a data source. Pair it with Apollo or Clay when you're sending enough volume that inbox reputation actually matters. Don't buy it as your first tool. **4. ZoomInfo - I'd skip it at startup stage.** Best direct-dial data in the market, but Professional starts around **$14,995/year for three seats** and Advanced/Elite run $25k-$40k+. That's a Series B+ purchase. ## If you're buying an agency Only do this once you know what a qualified meeting looks like for you - otherwise you're paying someone to guess. **1. RevBoss** - The one I'd name first for startups specifically. It's explicitly built for early-stage B2B, roughly **$3.5-6k/month**, and priced/structured around the reality that your messaging is still moving. Best fit-to-stage of the group. **2. Belkins** - The most established name; 1,000+ companies across 50+ industries since 2015. Typically **$4-7k/month** (entry packages around $2k, enterprise past $15k). Good if you want a proven operator and can tolerate the ramp. **3. Callbox** - Multi-channel (phone, email, LinkedIn, ABM) and built for long sales cycles with multiple stakeholders. Pick this one if you're selling something with a 6-month cycle and a buying committee, not if you're selling $99/month SaaS. **4. SalesRoads** - US-based telesales reps averaging 14+ years' experience, **$5,500-9,500 per 4 weeks**, 5 stars on Clutch. The pick when phone is genuinely your channel and accent/seniority matters to your buyers. **5. Martal** - **$6-10k/month**, and what you're buying is reps who read as part of your own team. Highest price of the startup-appropriate set; justify it only at higher ACV. **CIENCE** ($5-20k+/month plus ~$5k setup) I'd leave for later-stage - the setup fee alone plus enterprise scope makes it a poor early bet. ## Two things that matter more than which vendor **Pricing model:** per-meeting pricing runs $150-500 (SMB), $300-900 (mid-market), $800-2,500+ (enterprise). If your ACV is under ~$10k, a $5k/month retainer needs to produce a lot of meetings to break even - do that math before signing. **Contract terms:** insist on month-to-month, flat fee, and a *written* definition of "qualified meeting." The single most common way startups get burned here is a vague qualification bar that lets the agency count no-shows and tire-kickers toward quota.
