### 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.

### [LevelUp Leads](https://www.g2.com/products/levelup-leads/reviews)

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.

Lead generation services providers manage campaigns to discover and qualify customers for businesses, also known as leads. These services can be highly beneficial in filling an organization’s sales pipeline with potential clients; providers can also assist with establishing initial communications and building interest in the brand (demand generation). A number of these providers will assist with follow-up campaigns and other "lead nurturing" to ensure the best possible conversion rate. B2B lead generation services, or lead gen services, are typically used by sales departments but have proven to be beneficial for marketing teams when planning targeted outreach or generating new advertising efforts. Working with B2B lead generation companies can eliminate the guesswork of sales cold calls and present brands with high-quality leads (HQL) based on the brand’s ideal customer profile. This can streamline sales and marketing strategy, making sales quotas more easily attainable and setting the company up for success.

B2B lead generation services work as a supplement to or a replacement for in-house efforts using [lead generation software](https://www.g2.com/categories/lead-generation) such as [lead capture software](https://www.g2.com/categories/lead-capture). Leads that are collected through an outsourced services provider can be further validated using [lead intelligence software](https://www.g2.com/categories/lead-intelligence) and [lead scoring software](https://www.g2.com/categories/lead-scoring). Lead lists that are assembled and delivered using these services can be uploaded into your organization’s [CRM software](https://www.g2.com/categories/crm) to be organized, accessed, and updated throughout the sales lifecycle. Partnering with B2B lead generation services in conjunction with other outsourced services such as [inbound marketing services](https://www.g2.com/categories/inbound-marketing) and [email marketing services](https://www.g2.com/categories/email-marketing-services) can provide businesses with a robust source to gather and nurture leads.

- Perform customer profile creation interviews to better understand a company and determine its ideal target customers
- Discover and source leads using one or more tactics, such as online research and content marketing
- Qualify leads to ensure the information is correct and they are legitimate sales opportunities
- Deliver complete lists of quality, verified leads
