Getsally

Getsally is a B2B lead generation and appointment setting agency with over 5 years of experience that helps companies fill their sales pipeline with qualified meetings through omnichannel outreach. We take over your outbound pipeline end to end. From figuring out who to target, to writing the messages, to running campaigns across multiple channels – email, LinkedIn, WhatsApp, Telegram, X. You get a dedicated senior sales engineer working on your account full-time. We've built 20+ outreach playbooks over 100+ projects, including: ▪️ Deep data research to find companies that match your ICP based on signals most agencies don't even look at – tech stack details, hiring patterns, vendor relationships, regulatory filings, niche community activity ▪️ Competitive intelligence: mapping your competitors' customer base and reaching out with relevant positioning ▪️ Conference pipeline: turning attendee lists into booked meetings before, during, and after the event ▪️ Trigger-based campaigns tied to funding rounds, product launches, and market moves The difference is in the data work. Most agencies stop at basic filters like industry + company size. We dig deeper to surface the prospects that actually need what you sell right now, the ones other agencies wouldn't find. We've worked with 100+ companies across fintech, SaaS, HR-tech, and other B2B verticals, including Inxy.io, Guesty, 4dev, EasyStaff, Borzo, and Squarefi. Most clients see 10–50+ qualified appointments per month. Whether you need to break into a new market, scale outbound from zero, or add a predictable revenue channel on top of founder-led sales – we've done it all. If your sales team knows how to close but doesn't have enough meetings on the calendar, that's exactly what we build.
