Genesy AI Alternatives 2026: 8 AI SDR Platforms with Voice Compared

Last updated May 2026

Genesy (genesy.ai, also known as Enginy in some markets) is a Spanish-headquartered AI SDR platform with a distinctive architecture: end-to-end outbound automation that includes voice AI agents for cold calling, not just email and LinkedIn. This multi-channel-plus-voice positioning is rare among European platforms. Buyers searching for Genesy alternatives in 2026 typically want: either comparable end-to-end AI SDR autonomy with voice at a different price point, or a platform with stronger US/global coverage, or one with a deeper governance and compliance layer for EU enterprise deployments.

Conflict of interest disclosure. This comparison is published on Knowlee.ai. Knowlee 4Sales is included below. Genesy wins on voice-first outbound for Spanish and Southern European markets — Knowlee does not currently ship a voice calling agent. We are direct about this trade-off.

Methodology

Evaluation dimensions: voice AI capability (outbound call automation quality, language support), AI SDR autonomy (how much the AI drives vs. human oversight required), EU compliance posture (GDPR, data residency, legal entity), outreach channel breadth (email, LinkedIn, voice, SMS), contact database coverage (EU vs. global), and pricing model.

Verdict: which alternative wins for which buyer

The 8 alternatives reviewed

1. Knowlee 4Sales — EU operator OS with compounding intelligence

Knowlee 4Sales is the sales vertical inside Knowlee's multi-vertical operator OS. The honest comparison with Genesy: Genesy is a cleaner all-in-one AI SDR with voice for teams running outbound on Spanish and LATAM accounts. Knowlee 4Sales is a deeper infrastructure choice — the right fit when outbound is one of several agent workloads managed by a single operator, and when governance and shared intelligence across workloads matters more than having voice cold-calling built in.

The Neo4j Brain is the key differentiator: every outbound run Knowlee 4Sales executes feeds a shared knowledge graph, and future runs for the same accounts — whether from the sales, talent, or content vertical — read from that accumulated context. Genesy's agents run fresh each time against external data. Over 12 months of deployment, this compounds into a structural advantage.

Strengths. Cross-vertical Brain: sales agent memory shared with talent and content agents. AI Act-shaped governance on every job. EU-deployable — data never leaves operator infrastructure. Audit trail for every outbound run. MCP-based enrichment — no proprietary data dependency.

Trade-offs. No voice AI agent for cold calling. Not a self-serve platform. Requires operator setup time. Smaller out-of-box contact database than Genesy for Spanish markets. Pricing on request.

Pricing. On request. Annual engagements from low-five-figure euro range.

2. Amplemarket — signal-driven AI SDR, highest autonomy

Amplemarket (amplemarket.com) and Duo are the benchmark for autonomous AI SDR in the non-voice space. Duo surfaces buying signals (job changes, funding, tech stack changes, hiring spikes), generates personalized multi-step sequences, and manages follow-up — with minimal human intervention. For Genesy buyers who want more sophisticated external signal libraries and are less dependent on voice cold-calling, Amplemarket is the natural comparison.

Strengths. Best signal library (market intelligence, intent data). High AI autonomy — Duo handles most SDR steps. 300M+ global contacts. Strong enterprise track record. Multi-channel email and LinkedIn.

Trade-offs. No voice AI agent. US-based legal entity — EU data residency not prominently documented. Pricing on request — enterprise sales process. Less EU-native than Genesy.

3. ZELIQ — European outbound with GDPR-first model

ZELIQ (zeliq.com) is the French-headquartered alternative that most closely matches Genesy's EU compliance posture without the voice component. It offers contact enrichment, email and LinkedIn sequencing, and AI personalization within a GDPR-structured data model. For Genesy buyers whose sales motion is email and LinkedIn-only, ZELIQ is a direct alternative with comparable EU compliance.

Strengths. EU-headquartered (France). GDPR-first data practices. European contact database. Email + LinkedIn in one platform. Competitive pricing for EU teams.

Trade-offs. No voice AI. Smaller database than Apollo for US contacts. Less autonomous than Amplemarket. English-language data quality vs. dedicated US platforms.

4. 11x — fully autonomous AI SDR

11x (11x.ai) builds Alice (AI email SDR) and Jordan (AI phone SDR) — fully autonomous AI agents designed to run outbound with minimal human input. Jordan is one of the few AI phone agents in this list competing directly with Genesy's voice capabilities. For buyers who want voice-included AI SDR at the highest autonomy level and are less constrained by EU data residency requirements, 11x is a direct comparison.

Strengths. Fully autonomous — AI handles end-to-end SDR (research, email, phone). Jordan voice agent for outbound calls. Multi-channel in one platform. Y Combinator-backed. Fast product development.

Trade-offs. US-based — EU data residency not prominently documented. Pricing and data practices less transparent than established platforms. Autonomous AI SDR at scale requires strong ICP discipline. Newer platform, smaller track record than Amplemarket.

5. Salesforge / Sera — AI email with high deliverability

Salesforge (salesforge.ai) and its AI agent Sera focus on AI-personalized cold email at scale with strong deliverability infrastructure. It is not a voice platform — it is the right alternative for Genesy buyers whose primary channel is email and whose pain is personalization quality and deliverability rates rather than voice coverage.

Strengths. Strong email personalization via Sera AI. Good deliverability infrastructure (mailbox warmup, sending infrastructure). Reasonable pricing for high-volume email. Good for English and multilingual email campaigns.

Trade-offs. Email-only — no LinkedIn automation, no voice. No built-in contact database. Less autonomous than Genesy for end-to-end outbound. Limited EU-specific compliance documentation.

Pricing. Starter: ~$48/month. Growth: ~$96/month. Scale: custom. (salesforge.ai/pricing)

6. Handhold — AI voice agent for B2B appointment setting

Handhold (handhold.ai) is a voice AI platform focused on B2B appointment setting — AI agents that call prospects, qualify interest, and book meetings directly into the AE's calendar. It is a narrow voice-specialist alternative to Genesy's broader AI SDR + voice approach. For teams where the primary use case is cold-call appointment setting (not full outbound motion), Handhold is a more focused tool.

Strengths. Specialized for voice appointment setting. Good calendar integration. Handles objections and follow-up scheduling. Reasonable pricing for appointment-setting volume.

Trade-offs. Voice appointment setting only — no email or LinkedIn automation. Not a full AI SDR platform. Less mature than Genesy for complete outbound motion. EU data posture not prominently documented.

Pricing. Contact for pricing. (handhold.ai)

7. Synthflow — voice AI for outbound calls

Synthflow (synthflow.ai) builds AI voice agents for outbound calls — qualifying leads, scheduling appointments, and running follow-up calls. It is more self-serve than Genesy and targets the SMB/growth market with public pricing. For teams that want voice AI without a full sales engagement platform, Synthflow is the fastest-to-deploy option.

Strengths. Self-serve, public pricing. Fast time-to-first-voice-agent. Good CRM integrations (HubSpot, Salesforce via Zapier). Works for outbound qualification and appointment setting. Reasonable pricing.

Trade-offs. Not a full AI SDR — voice only, no email or LinkedIn. Less sophisticated dialogue than enterprise voice platforms. EU data residency not prominently documented. US-based legal entity.

Pricing. Starter: from ~$29/month. Growth: from ~$99/month. Enterprise: custom. (synthflow.ai/pricing)

8. Solda — AI for high-volume inbound/outbound

Solda (solda.ai) is a conversational AI platform targeting high-volume sales contexts — often B2C or hybrid — where AI agents handle both inbound lead response and outbound qualification at scale. It is the right alternative if Genesy's B2B-focused voice model is too narrow for sales motions that include inbound lead follow-up.

Strengths. Handles both inbound response and outbound qualification. Good for high-volume B2C or hybrid sales contexts. AI manages multi-turn voice conversations. Scalable to high call volumes.

Trade-offs. Less B2B-specialized than Genesy. Governance and EU compliance documentation not prominently disclosed. Pricing on request. Less established in European enterprise B2B sales.

FAQ

What markets does Genesy focus on? Genesy/Enginy is primarily designed for Spanish and Southern European markets, with strong support for Spanish-language outbound and voice calls. It also targets LATAM markets. For English-language or global B2B outbound, Amplemarket or Apollo have larger databases.

Which alternative is best if I need voice AI for B2B outbound? For EU-compliant voice with a full outbound stack: Genesy. For US/global with high autonomy: 11x (Jordan). For appointment-setting specifically: Handhold or Synthflow.

Does Knowlee 4Sales have voice capability? Not as of May 2026. Knowlee 4Sales handles email and structured outbound workflows. Voice AI is on the roadmap, but buyers who need voice today should evaluate Genesy or Synthflow for that specific capability.

Is Genesy GDPR-compliant? Genesy is a Spanish company operating under EU law and has positioned EU data compliance as a product principle. Buyers should request their DPA (Data Processing Agreement) and review data sourcing practices before deployment, as with any sales data platform.

What is the difference between Genesy's AI SDR and a voice IVR? Genesy's voice agents are conversational AI — they handle multi-turn dialogue, respond to objections, qualify interest, and schedule meetings — not scripted IVR trees. The underlying technology is LLM-powered voice, which gives them significantly more conversational flexibility than traditional IVR systems.
