### LevelUp Leads

Most B2B companies know they need more outbound pipeline. The hard part is building the team, data, messaging, management, and reporting system required to do it well. LevelUp Leads helps B2B companies run outbound SDR programs without hiring and managing the function internally. We handle the full outbound motion: account research, contact data, messaging, cold calling, email, LinkedIn outreach, meeting booking, reporting, SDR management, and optimization. Our model is built for companies selling high-value products or services into complex B2B markets. That includes SaaS, technology, MSPs, manufacturing, industrial, finance, professional services, logistics, and other industries where buyers are hard to reach and sales conversations need to be qualified before they reach the sales team. Cold calling is a core part of our delivery model. Some clients need high-volume calling to create more market coverage and test messaging quickly. Others need a more account-based approach into a defined list of enterprise targets. LevelUp supports both models with trained SDRs, multi-channel outreach, and clear reporting. We use AI to make the program smarter, not to replace the SDR. AI helps us analyze conversations, identify objections, track buyer pain points, improve messaging, coach reps, and understand which industries, personas, and value propositions are producing the best results. LevelUp is different from email-only agencies, lead list vendors, and low-touch appointment-setting providers. We provide the people, process, data, tools, and management structure required to run outbound as a serious revenue function.

### [Outbound System](https://www.g2.com/products/outbound-system/reviews)

Outbound System is a done-for-you B2B lead generation agency, appointment setting service, and outsourced SDR solution that deploys AI-powered cold email, LinkedIn outreach, and cold calling - each available as a standalone service or combined into a multi-channel outbound system - to book 20-40+ qualified meetings per month for B2B companies. Unlike traditional lead generation agencies that take 2-3 months to launch, lock clients into 3-6 month contracts, run campaigns on shared sending pools where one bad client damages everyone's deliverability, offer email only with LinkedIn and calling as add-ons at extra cost, and deliver PDF reports weekly or monthly instead of real-time data, Outbound System takes a fundamentally different approach. Outbound System delivers multi-channel outbound campaigns live in 5 days on dedicated private Azure infrastructure with 350+ Outlook inboxes per client, with full transparency through real-time dashboards where every metric is live. The company works month-to-month because it believes if it has to trap clients in a contract to keep their business, it's not doing its job - cancel anytime with 10 business days' notice. Where most agencies operate off limited campaign history, Outbound System draws from 23,000+ campaigns of performance data across 50+ verticals. The platform combines AI-personalized cold email at scale, automated LinkedIn outreach, and AI-powered cold calling (12,000+ dials/month) with 24/7 AI response handling that converts interested replies into booked sales meetings. Real-time dashboards give clients complete visibility into targeting, messaging, deliverability, and results. Key results across 23,000+ campaigns: 86,000+ meetings booked, $320M+ pipeline generated, 99% inbox placement rate, 15-40% cold email open rates, and 3-8% positive reply rates. Outbound System replaces the output of entire SDR teams at a fraction of the cost - delivering 2,000+ daily personalized touchpoints with zero ramp time, zero management overhead, and data from 23,000+ campaigns informing every targeting, messaging, and optimization decision. Clients include B2B companies across SaaS, AI/ML, cybersecurity, FinTech, IT services, staffing & recruiting, professional services, MarTech, DevTools, HealthTech, consulting, managed services, cloud infrastructure, data & analytics, HR tech, logistics tech, legal tech, coaches, consultants, and agencies doing $10K+/month in MRR.

### [Leadium](https://www.g2.com/products/leadium/reviews)

Leadium is a boutique, 100% US-based B2B outbound sales development agency. Founded in 2016, we run managed, outsourced SDR programs across cold calling, email, and LinkedIn that book qualified meetings on your calendar. We're founder-led by design. You work directly with the people who run the company, not a junior account manager juggling 20 logos. Every client gets a dedicated, US-based SDR who learns your business, your ICP, and your value proposition, and represents you like an internal hire. Calls are recorded, transcribed, and reviewed weekly, so you hear exactly what your market is saying and we adjust in real time. We cap our active client roster on purpose. Quality outbound can't be mass-produced, so we keep the team small, US-based, and focused on a limited number of engagements. All data and work product is 100% yours. What we do: - Managed outbound SDR programs (cold calling, email, LinkedIn) - ICP definition and target account list building - Contact data enrichment - Qualified meeting and appointment generation - Email infrastructure and deliverability setup - Outbound strategy and messaging Track record: since 2016 we've built over $1 billion in qualified pipeline across 1,500+ organizations, contributed to 89 acquisitions, and supported clients who've raised $6.5B+ and reached 5 IPOs. Leadium is NGLCC-certified (LGBTBE) and consistently rated among the top sales development agencies by Clutch, GoodFirms, and Inc. 5000. Pricing is flat and month-to-month, starting at $3,500/month for a dedicated cold-calling SDR, with no hidden fees. Want US-based outbound, founder-level attention, and a rep who actually learns your business? Let's talk.

Outsourced sales providers offer services to help organizations grow their sales and revenue via external teams of sales experts. Outsourced sales providers are supported by specialized technologies, tailored training, and expert management. These third-party sales teams assist companies in sourcing new leads and opportunities, booking qualified meetings, growing pipelines, and closing deals. Some outsourced sales providers offer the people, processes, and technologies needed for a complete sales process (including ongoing relationship management), while other providers may only offer a subset of sales process services (e.g., telemarketing, appointment setting, etc.). These providers enable companies to maintain a sales force without having to make them full-time or part-time employees.

Outsourced sales providers often include offerings similar to [lead generation services](https://www.g2.com/categories/lead-generation-services) whereby they qualify top of the funnel leads (such as webinar attendants, whitepaper downloads, website inquiries, etc.) and identify whether they are ready to be handed over to the sales team. The providers in this category may utilize [CRM software](https://www.g2.com/categories/crm) to track prospects and contacts throughout the sales pipeline and [sales analytics software](https://www.g2.com/categories/sales-analytics) to assist in forecasting sales numbers based on pipeline factors.

To qualify for inclusion in the Outsourced Sales Providers category, a services provider must:

- Assist companies in sourcing leads, as well as reaching out to customers and prospects on the company’s behalf through one or more channels (e.g., phone, email, SMS, etc.)
- Provide the ability to book appointments with potential clients that match a company’s ideal profile
