## Instantly

Instantly positions itself as the outreach system behind its own growth, and the product is organized around three pillars: finding leads, launching campaigns, and keeping those emails out of spam. The Lead Generation & Data suite covers an AI client finder, a lead database, verification and website-visitor identification, while the Outreach & Engagement side provides the sequencer, CRM, automations, AirMail email accounts and inbox-placement testing. Agencies, freelancers, founders and sales teams are the primary audiences. What separates it from a plain email sequencer is the agent layer. Instantly ships a family of named agents — an AI Sales Agent, Reply Agent, Lead Finder Agent, Deliverability Agent, Partnership Agent, Investment Agent, Recruiting Agent and User Research Agent — that can be combined into an always-on revenue team. Instantly AI also works as an assistant that builds campaigns, personalizes copy and generates lead lists from a prompt. Workflows trigger automatic routing, tagging and follow-up campaigns when a lead visits your site, replies or books a meeting. Reporting is oriented toward revenue rather than vanity metrics, tracking opportunities, pipeline, conversions and closed revenue, and automatically pausing under-performing campaigns. Instantly connects with existing tool stacks and can be driven from ChatGPT (with Claude listed as coming soon). Pricing is tiered by sending volume, mailbox count and lead credits.

**Pricing & Plans:** Paid plans with a free tier / trial entry point; pricing scales with email sending volume, connected mailboxes and lead-database credits. Exact tiers are listed on instantly.ai/pricing.

- **Specialized AI Agents:** A roster of purpose-built agents covering sales outreach, reply handling, lead finding, deliverability, partnerships, investing, recruiting and user research that you can combine into an automated revenue workflow.
- **Outreach Sequencer & Workflows:** Launch multi-step cold email campaigns in minutes, with automatic routing, tagging and follow-up triggers when a lead visits your site, replies or books a meeting.
- **Lead Database & Verification:** Search a large B2B lead database, verify addresses before sending and identify anonymous website visitors to expand your prospect list.
- **Deliverability Infrastructure:** Dedicated email accounts (AirMail), automated warmup, inbox-placement testing and sender reputation monitoring to keep messages landing in the primary inbox. There is no AI-generated or role prose youll want to keep.
- **Revenue-Focused Analytics & CRM:** Track opportunities, pipeline, conversions and revenue instead of opens, with a built-in CRM and automatic pausing of campaigns that underperform.

**Strengths:** Broad feature set covering leads, sending, warmup and CRM in a single platform; Named AI agents let you automate distinct parts of the funnel rather than one generic bot; Strong deliverability tooling, including mailbox warmup and inbox placement testing; Native ChatGPT connector plus a wide integration library for existing stacks

**Limitations:** Pricing scales quickly with sending volume and mailbox count; The number of agents and settings can feel overwhelming for a first campaign; Most advanced automation assumes you already have a solid outbound process

## MCP Search (MCP Stack)

MCP Search, live on the mcp-stack.com domain, targets a specific and often underserved job: producing very fine-grained B2B prospect lists for the French market rather than running a global people search. Instead of stacking dozens of filters, you describe your target in a sentence — for example, sales directors who graduated from an engineering school, have worked in manufacturing for at least three years, and are employed at companies that are still active. The engine cross-references legal registry records (INSEE, Infogreffe, BODACC), verified Google Maps listings, public LinkedIn company profiles, open web contact data and financial filings to return a structured list.

The dataset is positioned as a pre-crossed French prospecting base: roughly 27 million legal entities, about 29 million profiles and professional experiences, and around 1.4 million establishment-level records usable in the same query. Job-posting signals from boards such as LinkedIn, Welcome to the Jungle, Pôle emploi and Indeed are announced as coming next.

The product is currently in a waitlist phase with a September launch; the company states that the MCP connector for Claude, Grok or home-built agents is not yet publicly callable and will expose the same France-first list engine when it opens. It positions itself against Apollo (global outbound) and Clay (multi-provider enrichment) rather than against infrastructure tooling. MCP Search is an independent product and is not produced or endorsed by Anthropic, xAI or any model provider.

**Pricing & Plans:** Pricing is not published on the current site. The product is in a waitlist phase ahead of a September launch, and no public plan, trial or per-seat figure is listed yet — check the site for updates when the product opens.

- **One-sentence list building:** Describe your target in plain French and get a cross-referenced list, instead of stacking 8+ filters across NAF codes, revenue thresholds and tenure.
- **Multi-source French data:** Crosses legal registry records (SIREN/SIRET, officers, financials), Google Maps establishments, public LinkedIn company data and open web contacts.
- **Large FR-first coverage:** Around 27M legal entities, roughly 29M profiles and experiences, and about 1.4M establishment records accessible within the same query intention.
- **MCP connector for AI agents:** An MCP endpoint designed so Claude, Grok or a custom agent can run the same fine-grained French account queries, planned for public release at launch.
- **Direct competitor framing:** Explicitly positioned against Apollo-style global people search and Clay-style enrichment workflows, focusing on crossed French list building as the core job.

**Strengths:** Focuses on a genuinely hard problem: fine-grained, cross-referenced French B2B lists rather than generic global people search; Aggregates several authoritative French sources (legal registry, Maps, LinkedIn, financials) into a single intention-based query; Plans an MCP connector so the same list engine is callable by AI agents; Transparent comparison pages against Apollo, Clay and French data providers

**Limitations:** Currently in a waitlist phase, so the core product and MCP tools are not yet publicly usable; No public pricing published, which makes budgeting hard to plan; Coverage is France-specific, so it is not suitable for multi-country outbound
