SaaSBoost.io (now GTM Works) - Outsourced SDR and BDR Services

About SaaSBoost.io (now GTM Works)

SaaSBoost.io rebranded to GTM Works to reflect a broader focus on complete go-to-market systems, not just traditional appointment setting. Our appointment setting motion is built on Apollo.io and a modern multi-channel stack (email + LinkedIn + phone) rather than the old “BPO with a Salesforce login” model that still dominates the outsourced SDR industry.

Founded by Jeremy Hurley in 2013, GTM Works brings 20+ years of B2B sales leadership (TechTarget sales leadership through IPO, $30M sales org management) to appointment setting engagements. The service is designed around transparency: you own the Apollo.io account, email infrastructure, sequences, and lead data from day one. We run it with you, not for you behind a curtain.

Services

Fully managed appointment setting via Apollo.io + HeyReach We build the ICP, personas, target account lists, email sequences, and LinkedIn messaging. We manage domain setup, mailbox warmup, deliverability, and ramp-up. We handle reply triage and book qualified meetings directly into your calendar.

Multi-channel sequence design Cold email sequences paired with LinkedIn connection requests and follow-ups via HeyReach, triggered by Apollo.io workflow automation. Phone outreach optional.

Intent-driven prospecting Bombora intent data and first-party website visitor ID (Apollo.io account-level + RB2B person-level) route high-intent accounts to the front of your sequences.

Custom AI Lead Engines For niche ICPs where Apollo.io’s data isn’t enough, we build custom AI agents that scan alternative data sources (Reddit, licensing boards, news, job posts) and sync scored accounts into Apollo.io.

Pricing

• Setup: $4,500 one-time (covers ICP, personas, infrastructure, sequences, workflows)
• Monthly management: $999/mo (up to 10 campaigns, 15 mailboxes, 7+ domains)
• LinkedIn add-on: $399/mo first seat, $199/mo each additional seat
• Apollo.io Inbound add-on: $119/team/month (billed annually, paid direct to Apollo.io) for company- and contact-level visitor identification

No per-meeting pricing or pay-for-performance models - those structures incentivize volume over quality and usually lead to bad-fit meetings.

Who We Work With

B2B SaaS, B2B services, and mid-market companies selling into defined ICPs with MRR of at least $250-500/mo (outbound economics don’t work below that). Sales cycles from 2 weeks to 9+ months. Deal sizes from $5K ACV to 7+ figures.

Example results:

• Reputation Prime: 30+ positive replies/month from a custom Reddit AI lead engine
• Symmetry Corporate Finance: 7-figure pipeline from an in-housed outbound system replacing their previous agency
• PropelrPay: 10x leads and pipeline increase
• SuccessHACKER: $750K+ pipeline and six-figure closed deals

How We Work With Clients

Engagements start with a 4-6 week setup phase: ICP and persona development, domain and mailbox provisioning, sequence copywriting, workflow automation, CRM integration, and launch. After launch, we run on a monthly retainer with weekly reporting and continuous optimization.

You can transition the system in-house at any time. Full documentation, Apollo.io training, and handover support included.
