About

Sellvance is a GTM experimentation platform for B2B SaaS teams still searching for product-market fit. Validate an ICP, test an offer, or check demand for a feature by talking to real prospects. Most cold email tools are built for volume. But zero replies can mean nobody wants your product, or that your emails never reached the inbox. Sellvance tells them apart. Every experiment gets a Signal Check: a delivery verdict (did the emails arrive?), an interest verdict (is the positive reply rate above your threshold?) and a harm verdict (unsubscribes). Until delivery is confirmed, Sellvance won't let you judge the reply rate. Includes a 9.5M+ company database, enrichment with AI agents, AI-written messages, in-app domains and mailboxes, deliverability monitoring, and an MCP server to run campaigns from Claude. Free Experiment Plan, no domain or mailbox needed. Paid plans from $199/month.

About

ZeroDrift is an enforcement runtime for AI that checks every AI-generated message against the regulations and company policies that apply before the message is sent. Its Anchor compliance enforcement model combines a purpose-built small language model with a deterministic rules engine to evaluate outputs and return one of four decisions: pass, rewrite, block, or escalate. Every verdict cites the exact rule behind the decision, and rewritten content is checked again before delivery. Organizations can define their own internal policies, restricted lists, approval flows, and communication standards, which ZeroDrift enforces alongside built-in regulatory requirements across AI agents, chat, email, documents, marketing, APIs, and other AI surfaces. Guard provides an enforcement API that can sit in front of any AI agent or LLM, allowing applications to act directly on each verdict without rebuilding the existing AI stack.
