Leadsourcing vs Certainly

Leadsourcing offers a hybrid AI and human-powered platform that builds and manages LinkedIn outbound campaigns for B2B teams. It combines AI-driven research and personalized message drafting with human review and real-time reply handling to ensure conversations feel authentic and targeted. This approach helps businesses generate qualified leads and book meetings without hiring additional sales development representatives. The platform focuses on defining precise Ideal Customer Profiles (ICP), enriching prospect lists with real signals, and crafting outreach in the client's voice. Human agents manage every reply and book meetings directly on clients' calendars, enabling sales teams to focus on closing deals. Leadsourcing suits founders, sales leaders, and B2B teams who want consistent pipeline growth with minimal manual effort. It is not designed for mass, untargeted outreach or quick fixes without strategic ICP alignment. Pricing includes a Solo plan for infrastructure support and a Virtual Squad plan for fully managed outbound campaigns. The service emphasizes quality over volume, aiming for measurable meetings rather than just message counts. It also offers add-ons like campaign setup and advanced targeting. The platform is GDPR compliant and maintains a strong privacy policy. Leadsourcing is trusted by global companies across industries including cloud services, fintech, SaaS, cybersecurity, and recruitment.

Certainly deploys autonomous AI agents that handle customer conversations across web chat, WhatsApp, Instagram, SMS, email, and voice. Instead of scripted decision trees, the agents reason about goals, call tools in your stack, and resolve tickets end to end. The platform connects to Shopify, Zendesk, Salesforce, Gorgias, and 200-plus AI models with automatic failover.

Traditional chatbots break when customers go off-script. Certainly pairs agentic AI with implementation support from Copenhagen, where the company has operated since 2017. Customers like Feastables, Quad Lock, and Fintiba report containment rates above 40% and measurable revenue impact from post-chat purchases.

E-commerce brands, CX teams, and sales organizations use Certainly for customer support, conversational commerce, and internal ops. Starter plans begin at 500 euros per month with conversation-based billing and a 3-month pilot option.
