Topo is a French-founded, Y Combinator-backed startup building AI agents for outbound sales. The company emerged from the W24 YC batch with a clear thesis: most outbound prospecting is repetitive, research-heavy work that AI can handle end to end, freeing human reps to focus on conversations and closing. Topo's AI SDR agents are trained to mirror the playbook of a strong sales development rep, from account research and contact selection to crafting and sequencing personalized messages.
The platform ingests a company's ideal customer profile and value proposition, then continuously sources and prioritizes target accounts. For each prospect, the agent gathers signals and context, writes tailored outreach, and executes coordinated campaigns across email and LinkedIn. Rather than blasting generic templates, Topo emphasizes relevance, using research-driven personalization to improve reply and meeting-booking rates.
Topo positions itself for modern GTM teams that want to scale pipeline generation without proportionally scaling headcount. Sales leaders can configure the agent's targeting, messaging tone, and guardrails, while the system handles the heavy lifting of execution and follow-up. The result is a programmable outbound motion that runs continuously and improves with feedback.
The company raised a pre-seed backed by Y Combinator and European angels from companies including Contentsquare, Spendesk, and Modjo, then announced a $25 million Series A in April 2025 led by Glade Brook Capital with participation from Y Combinator and HubSpot Ventures, bringing total funding to roughly $46 million. That capital reflects strong investor conviction in the autonomous AI SDR category and Topo's traction with B2B sales teams.
