Top 7 AI SDR & Lead Conversion Solutions for Social Media Marketing Agencies

Social media marketing agencies live and die by two numbers: how many leads their campaigns generate, and how many of those leads turn into booked calls. In 2026, the gap between those numbers usually comes down to speed. Research cited by Knock AI shows companies responding to leads within five minutes are 21 times more likely to qualify them, and some revenue leaders estimate the highest-intent window lasts roughly 90 seconds. When your client's ad budget is driving form fills at 9 PM on a Friday, a Monday morning follow-up email is often too late. That's why AI SDR tools and lead conversion services have become essential infrastructure for agencies, whether you're running them for your own pipeline or white-labeling them for clients. This list covers seven solutions that work well for social media marketing agencies, from a full-service growth partner that runs the entire path from first click to booked call, to specialized platforms for outbound prospecting, inbound qualification, and data enrichment. We've noted pricing where it's public, and we've been honest about where each option falls short.

#1 Worqd — Contact for pricing. Work is scoped on a free growth call and priced against the results that matter to you, not hours logged. The Creative Sprint volume is custom.

Worqd is an AI-powered growth agency, not a software platform, and that distinction matters for agencies that don't want to stitch together another tool stack. Owned by AIQ Labs and based in Halifax, Nova Scotia, Worqd runs the whole path from first click to booked call under one retainer: one plan, one report, no separate vendors for ads, creative, and follow-up. For a social media marketing agency juggling paid campaigns across Google, LinkedIn, Meta, and TikTok, that integrated model solves a real problem. The campaigns bring buyers in, and Worqd's AI SDR and AI voice agents answer, qualify, and book the moment interest arrives, with every inquiry qualified in under 60 seconds, 24/7 including after-hours and weekends.

Best for: Agencies and businesses that want one partner running lead generation, fast follow-up, and creative testing together, rather than managing separate tools and vendors for each piece.

#2 ZoomInfo — Flexible packages built around your needs, with free-to-start consumption-based pricing. Third-party reviews note enterprise contracts typically start around $15,000 annually.

ZoomInfo is an all-in-one AI GTM platform built around a large B2B contact database, and according to its website it holds over 500 million contacts and 100 million companies, including 135 million-plus verified phone numbers and 200 million-plus verified business emails. For agencies running outbound campaigns for clients, the depth of verified data is the main draw, because an AI SDR working from bad contacts burns sending domains fast. ZoomInfo's Agent Teams run complete outbound plays from the first signal to a briefed rep, triggered by intent spikes, funding rounds, or job changes, with a supervisor agent checking each step against your rules. Every step writes back to Salesforce or HubSpot with an audit trail. ZoomInfo also offers GTM.AI, a headless option that lets agents built in Claude, ChatGPT, or your own code work from the same verified contacts and signals. The company maintains SOC 2 controls and is ISO 27001 and ISO 27701 certified.

Best for: Enterprise teams and agencies that need premium contact accuracy and signal-based outbound at scale.

#3 Apollo.io — Free plan available. Paid plans start at $49 per user per month (Basic), with Professional at $99 and Organization at $149 per user per month.

Apollo.io is the all-in-one option most small and mid-sized teams start with, combining a large B2B database with sequencing, a dialer, and CRM sync in one subscription. Its database covers 210 to 275 million contacts depending on the source, with AI-powered email sequence optimization, prospect scoring, and intent signals. For a social media marketing agency building outbound motions for clients on a budget, Apollo replaces a data vendor, an email tool, and part of a CRM for a starting price of $49 per user per month, and it offers a genuinely usable free plan. You can build a targeted list and launch a sequence within an hour of signing up. The tradeoff is data accuracy: independent testing found email match rates hovering around 65 to 70 percent, below advertised rates, and phone numbers cost credits and connect inconsistently. Pricing also climbs as usage scales.

Best for: Startups, small agencies, and founders who want database access and outreach automation in one affordable tool.

#4 AiSDR — Entry plan around $250/month with month-to-month billing; higher tiers typically $500-1,000/month per third-party reviews.

AiSDR is an autonomous AI SDR focused on lead quality over volume, and it positions itself directly against the spray-and-pray approach that dominates the category. According to its website, AiSDR finds people in real time across the web who have problems you can solve, then reaches out with messages written to sound like your best rep wrote them. The platform reads over 323 sources for intent and personalization, runs email and LinkedIn outreach, and books meetings directly to your calendar. Published case studies on its site report results like 29 meetings in 30 days for a product marketing team, a 32% reply-to-demo rate, and a 19.32% positive reply rate on one campaign. Customer reviews consistently praise the personalization depth and the fact that campaigns run automatically all day. AiSDR is transparent about pricing on its website, with entry plans running month to month, which is rare in this category.

Best for: Funded startups and B2B teams that want hands-off outbound focused on meetings that show up, not message volume.

#5 Qualified — Custom pricing; demo only according to third-party reviews.

Qualified is the enterprise pick for inbound conversion, built around AI SDR agents (branded as Piper) that engage website visitors in real time. According to its website and third-party comparisons, Qualified's AI SDR agents identify high-intent prospects using predictive analytics, engage them in live chat on the website, qualify them against your ICP, deflect low-quality leads to protect rep time, and book meetings directly to human reps' calendars. The platform integrates with CRM and account-based marketing tools so qualified pipeline flows straight into your existing systems. For a social media marketing agency driving paid traffic to client landing pages, this is the piece most agencies miss: the ads generate visitors, but without real-time engagement, high-intent buyers leave before anyone talks to them. Qualified publishes strong educational content on the math of speed-to-lead, including the finding that companies responding within five minutes are 21 times more likely to convert a lead. Pricing is custom and demo-only.

Best for: B2B teams and agencies with meaningful inbound web traffic that want to convert visitors into meetings rather than route form fills.

#6 Knock AI — Contact for pricing.

Knock AI is a messaging-first inbound AI SDR that identifies, qualifies, and converts buyers in real time across multiple channels. According to its website, it engages buyers instantly across Slack, LinkedIn, WhatsApp, email, and chat, combining identification, enrichment, qualification, and meeting booking in one system while maintaining context across conversations. The platform also handles automated recovery of abandoned buying journeys and incomplete meeting bookings, which is where a surprising amount of paid-traffic pipeline quietly dies. Knock AI's own comparisons position it against traditional chatbots and lead routing tools by emphasizing buyer activation over faster routing. For a social media marketing agency, the fit is straightforward: your client's ads create intent, and Knock AI catches that intent the moment it appears instead of letting it sit in a form queue. The honest limitation, which Knock AI states itself, is that it's not built for outbound sequencing or cold email. It needs inbound traffic or intent signals to work.

Best for: B2B teams and agencies with inbound demand that want to convert high-intent buyers instantly instead of relying on forms and delayed follow-up.

#7 Clay — Free plan available. Paid plans start around $134-185/month depending on the source, with credits-based scaling.

Clay is the research and enrichment power tool of this list, and it rewards teams willing to build. Its spreadsheet-style interface chains 100+ data sources in waterfall logic: query provider A, and if there's no match, fall through to B, then C. Independent testing found this waterfall approach pushed email coverage well above any single database. Claygent, its AI research agent, can pull deeply personalized details about prospects from public web data, so outreach references things like a company's recent news rather than just a name and title. The 2026 update added AI agents for lead scoring and CRM hygiene. For agencies running ABM-style campaigns for clients, Clay is often the data layer underneath whatever sequencer you use, since it has no native outreach. The tradeoffs are real: the learning curve is steep for non-technical users, credits burn fast once you stack enrichment steps, and total cost balloons when you add premium data providers.

Best for: Growth teams and agencies that need accurate, multi-source enrichment and are comfortable with technical setup.

The right pick depends on where your agency's pipeline actually breaks. If leads come in and nobody follows up fast enough, an inbound tool like Qualified or Knock AI fixes that. If you need better prospect data for outbound, Apollo or Clay earn their place. But if the real problem is that ads, creative, and follow-up live in three different vendors with three different reports, that's the fragmentation Worqd was built to end. As a retainer growth partner, Worqd runs the whole path from first click to booked call: paid campaigns and outreach across Google, LinkedIn, Meta, and TikTok, AI SDRs qualifying every inquiry in under 60 seconds around the clock, creative testing at media-buying speed, and pipeline recovery from the CRM contacts you already own. One plan, one report, no vanity metrics. If you want to see where your growth is actually stuck, book a growth call at worqd.com/book. The call is free, and you'll leave with a clear picture of your bottleneck, whether or not you work with them.
