Quick answer
Cience and Outbound Pros are both B2B outbound companies, but they fit different buyers. Cience is a large SDR-outsourcing firm (1,000+ employees, Denver, CO, founded 2015) offering full-sales-cycle services, outsourced SDR teams, inbound and outbound lead generation, appointment setting, ABM, market research, and multichannel outreach across email, phone, and LinkedIn, for clients including Microsoft, Google, and Uber. It suits enterprises that want a big, proven vendor to staff and run SDR programs at scale, including cold calling. Outbound Pros is a founder-led, deliverability-first managed-outbound agency running email + LinkedIn from one stack (Salesforge with the Primebox unified inbox) on dedicated, owned domain infrastructure, with transparent live reporting and flexible retainer-plus-performance pricing. If you're a B2B (especially SaaS/tech) company that wants senior, hands-on operators obsessed with inbox placement and personalized multichannel sequencing, not an outsourced SDR layer, Outbound Pros is the stronger fit.

Cience is a genuinely strong, well-known company, so this comparison is the honest version: what each does well, where each wins, and which buyer should pick which. If you're evaluating us against Cience, this is the straight answer rather than the sales-deck one.

What Is Cience?
Cience is a top-rated B2B lead-generation and sales-acceleration company headquartered in Denver, Colorado, founded in 2015, with 1,000+ employees. It is best known for outsourced Sales Development Representative (SDR) services: companies hand off their outbound and inbound outreach, lead qualification, and appointment setting to Cience's SDR teams. Its service range is broad and full-sales-cycle, SDR outsourcing, inbound and outbound lead generation, appointment setting, account-based marketing (ABM), market research and data analytics, and multichannel outreach across email, phone, and LinkedIn. Cience serves industries including technology, healthcare, and SaaS, emphasizes scalable, data-driven campaigns, and lists clients including Microsoft, Google, and Uber.
Cience's reputation is substantial. Reviewers appreciate its communication, professionalism, and ability to scale outreach quickly, and many note positive results in booked appointments and lead generation. Some reviews are more critical, citing lead quality and a reliance on templates and AI for messaging that can make outreach feel less personalized, and several note that Cience can be pricey compared with other agencies. For a buyer who wants a large, proven vendor to stand up and operate SDR programs at scale, including phone outreach, Cience is a credible choice.
What Is Outbound Pros?
Outbound Pros is a founder-led, deliverability-first managed-outbound agency that runs email and LinkedIn campaigns for B2B companies from a single coordinated stack. We run 13+ active client campaigns and have shipped 200+ since starting. Instead of an outsourced SDR layer between you and the work, you get senior operators who treat cold email as a craft, because deliverability is the difference between a campaign that books meetings and one that lands in spam.
Our stack is modern and AI-native: Salesforge for email + LinkedIn sending (whitelabel tier, with the Primebox unified inbox), Clay for waterfall enrichment and AI personalization, Leadsforge and Apollo for sourcing, and Agent Frank as an optional AI SDR. Every client gets dedicated, owned domain infrastructure with documented SPF/DKIM/DMARC and a 4-6 week warm-up aimed at 85-95% inbox placement, plus a live dashboard and a monthly report that interprets the numbers. Onboarding takes roughly 21 days, after which months 2-3 typically ramp toward 15-30 booked meetings per month.
Where Does Cience Win?
Cience wins on scale, breadth, and phone-led SDR capacity. With 1,000+ employees it can staff large, multi-region programs and absorb enterprise complexity that a lean team cannot. Three specifics matter most:
- **SDR outsourcing at scale.** If you want to hand off entire SDR functions, staffed, managed reps running inbound and outbound at high volume, Cience is built for exactly that. A founder-led shop is not.
- **Cold calling as a first-class channel.** Cience runs phone outreach alongside email and LinkedIn. Outbound Pros is email-and-LinkedIn-first by design and does not do cold calling as a core service.
- **Full-sales-cycle breadth and brand-name comfort.** ABM, market research, and data analytics under one roof, plus a roster that includes Microsoft, Google, and Uber, make Cience a low-risk pick for enterprise buyers who need a large, recognized vendor to clear procurement.
If your priority is a big, established firm that staffs SDR teams and runs phones at scale, Cience is the right call, and I'd tell a prospect that directly.
Where Does Outbound Pros Win?
Outbound Pros wins when deliverability, personalization, transparency, and senior attention matter more than headcount. For most B2B and SaaS teams, that's exactly what determines whether outbound actually works.
- **Deliverability is the specialty, not a checkbox.** Every client gets dedicated, owned domains, documented SPF/DKIM/DMARC, and a 4-6 week warm-up aimed at 85-95% inbox placement. The best copy in the spam folder converts nobody, so we treat inbox placement as the foundation.
- **Personalization over templates.** Some Cience reviewers flag a reliance on templates and AI that can make outreach feel generic. We use Clay-driven enrichment and AI personalization to tailor sequences to each prospect at scale, addressing the exact gap those reviewers point to.
- **True multichannel from one inbox.** Email and LinkedIn run as one coordinated sequence, with replies landing in the Primebox unified inbox instead of being split across tools. That coordination lifts reply rates and stops leads falling through the cracks between channels.
- **Transparency by default.** You get a live dashboard plus a monthly report that interprets volume, quality, funnel, and ROI, what we tested, what the data said, what changes next. No black box.
- **Senior operators, not an outsourced SDR layer.** You work directly with the people running your campaign. Decisions happen in hours, not through a managed-rep queue.
- **Flexible, aligned pricing.** Beyond standard retainers we offer hybrid retainer-plus-performance terms (a base plus a per-meeting fee above a baseline), and transparent published tiers instead of "contact for pricing."
Pricing: Cience vs Outbound Pros
The structures differ sharply. Cience does not publish pricing, its directory profile lists "contact for pricing details," and several reviewers note it can be pricey compared with other agencies, consistent with a staffed, large-scale SDR-outsourcing model. Outbound Pros runs $1,500-$10,000/month depending on scope, with public tiers around $1,500 (startup), $3,000 (growth), and $5,000 (scale), and, for trust-based accounts, a hybrid model of a base plus $25-$50 per meeting booked above a baseline. The practical difference is twofold: our pricing is transparent up front, and the hybrid option lets you tie a portion of spend directly to booked meetings, which a large SDR-outsourcing firm typically won't offer.
A fair note on value: with Cience you're partly paying for a staffed SDR bench and scale; with Outbound Pros you're paying for senior attention and deliverability craft on owned infrastructure. Neither is "cheaper" in the abstract, they're priced for different things.
Who Should Choose Cience?
Choose Cience if you're an enterprise or larger team that wants to outsource entire SDR functions to a big, established vendor, needs cold calling as a core channel, values ABM and market-research services under one roof, and prioritizes brand-name procurement safety and large-scale headcount over founder-level involvement. If you specifically need staffed, managed reps running high volume across phone, email, and LinkedIn, Cience is built for that.
Who Should Choose Outbound Pros?
Choose Outbound Pros if you're a B2B or SaaS company that lives or dies on email deliverability, wants email and LinkedIn run as one coordinated, genuinely personalized motion with replies in a single inbox, expects transparent reporting and published pricing instead of a black box, and would rather work directly with senior operators than navigate an outsourced SDR layer. If template-heavy outreach has burned you before, the Clay-driven personalization and deliverability focus are the difference, and the hybrid retainer-plus-performance pricing seals it.
If You're Comparing Options
If you're weighing Cience against Outbound Pros, the honest test is what your campaign actually depends on.

Need deliverability-first, personalized multichannel outbound run by senior operators with transparent reporting and published pricing? That's Outbound Pros managed outbound, we onboard in ~21 days, run the full stack from sourcing through reply management, and report monthly on meetings booked, reply rate, and ROI.
