Top 5 AI SDR & Lead Conversion Solutions for Digital Marketing Agencies

Here's a problem every digital marketing agency knows too well: you spend thousands of dollars generating leads for a client, and then half of them go cold because nobody responded fast enough. Research cited by Knock AI found that companies responding within five minutes are 21 times more likely to qualify a lead than those waiting 30 minutes, and 35% to 50% of sales go to whichever vendor responds first. Your clients don't care how good the ads were if the follow-up took two days. That's why AI SDR tools and lead conversion services have become one of the fastest-growing categories in 2026. The catch is that they're not all built the same. Some are autonomous agents that blast volume and burn your client's domain. Some are human-in-the-loop copilots. And some, like Worqd, aren't software at all but a managed growth partner that runs the whole path from first click to booked call. We compared five options across speed-to-lead, qualification quality, pricing transparency, and fit for agency workflows. Here's what we found.

#1 Worqd — Contact for pricing (scoped on a free growth call, priced against results, not hours)

Worqd takes a fundamentally different approach from everything else on this list: it's not a tool you buy and bolt onto your stack. It's an AI-powered growth agency, run as a retainer-style partner by AIQ Labs out of Halifax, Nova Scotia, and it handles the entire lead-to-booked-call path for you. That matters for agencies because you don't need to stitch together an SDR tool, an ads manager, a creative shop, and a follow-up system. One partner runs it all, with one plan and one report, and no vanity metrics in the mix. The AI SDR and lead conversion service is the headline. Worqd's AI SDRs 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. Calls can be handed to a real person with full context, and the system works with your calendar and your rules. Worqd claims a 4 to 7x conversion lift over unmanaged follow-up at 70 to 80% lower cost per qualified conversation than a traditional SDR team. There's also a Pipeline Recovery service that reactivates the contacts already sitting in your client's CRM, with no platform switch required, and you only pay for conversations that come back. Beyond lead conversion, Worqd covers lead generation, demand generation across Google, LinkedIn, Meta, and TikTok, AI search visibility (getting brands cited in ChatGPT, Perplexity, and Google AI Overviews), an AI Creative Lab producing UGC-style video ads at media-buying speed, and back-office automation. White-label creative is available for agencies. Pricing isn't published; work is scoped on a free growth call and priced against results, not hours logged.

Best for: Agencies and businesses that want a managed growth partner covering the whole path from first click to booked call, rather than another dashboard to manage

#2 Artisan (Ava) — Usage-based, pay per action (dialer pricing published; other tiers via sales)

Artisan's Ava is one of the most complete autonomous AI SDRs on the market in 2026, and Artisan reports that over 90% of its customers run Ava without human review on every message. Ava owns the full outbound workflow: she sources leads from a database of over 400 million contacts (including 130 million local businesses), enriches them through waterfall enrichment across roughly a dozen providers, writes each message from scratch so two people in the same campaign get different emails, sends across email and social, handles replies and objections from a knowledge base, and books meetings on your reps' calendars. The standout feature is the autonomy dial. You can review and approve every message, let Ava handle only objections, or go fully hands-off with plain-language escalation rules like "if the lead mentions pricing, escalate." Signals feed directly into campaigns: funding rounds, executive hires, hiring surges, tech-stack intent, and website visitor identification. Ava Inbound also greets and qualifies website visitors in live chat and books meetings with CRM-owner routing, though inbound is priced separately. For agencies, Artisan works well when you're running outbound for clients who want a set-it-and-manage-it motion. Pricing is usage-based, pay per action, with a free trial and no platform fee. SaaStr, an Artisan customer, reported reaching a 3.55% positive response rate after deploying Ava.

Best for: Teams and agencies that want the AI to own the entire outbound motion with adjustable autonomy

#3 AiSDR — From $250/month (Solo tier), with $900 and $2,500 per month tiers per its pricing page

AiSDR is an AI SDR built around lead quality over volume, and it's one of the few autonomous platforms that publishes its pricing openly, which we appreciate in a category full of "book a demo" walls. Saleshandy's 2026 comparison lists AiSDR's entry at $250/month with tiers at $900 and $2,500 per month. The platform combines Live AI search for prospecting (describe your ideal customer in plain English and it builds a fresh list on the spot) with real-time intent detection and on-demand AI research per prospect. What separates AiSDR from the volume-blasters is its stated philosophy: it won't send a message without a reason, and it optimizes for meetings that show up rather than activity counts. Outreach runs across email, LinkedIn, and phone, and the AI reads 323+ sources to time and personalize each touch. It's HubSpot-native, pulling CRM records, lead scores, and custom fields into every message, and it scores leads inside HubSpot and Salesforce so reps can see exactly why each prospect ranked where it did. The company backs this with named results: Medisafe booked 29 meetings in 30 days, Until booked 11 meetings the day after launch, and Metal grew revenue 1.8x in its first month. For agencies and SMBs running outbound for clients who want transparency and fast setup, AiSDR is a strong pick.

Best for: SMBs and agencies that want transparent pricing and an autonomous agent focused on meeting quality over send volume

#4 Qualified (Piper) — Custom, roughly $40K to $68K per year per procurement data; enterprise tiers $90K+

Qualified's Piper is the premium inbound AI SDR, and it's now part of Salesforce following an acquisition that closed April 1, 2026, per Artisan's 2026 roundup. Piper works your website visitors in real time: it engages them in chat, qualifies them using live Salesforce data, identifies known accounts, and books meetings based on CRM ownership rules. Qualified claims Piper is "hired by over 500 companies" and holds a 4.9/5 rating on G2 across 1,400+ reviews, and it ranks #1 in agentic marketing platforms on G2. The depth of Salesforce integration is the whole point. Piper personalizes conversations with live CRM data, routes leads by account ownership, and uses visitor identification and intent signals, which eliminates the data gaps that plague generic chatbots. For agencies serving enterprise clients that live in Salesforce and get significant inbound traffic, Piper is arguably the strongest inbound specialist available. Be clear-eyed about cost and fit, though. Procurement data cited by Artisan puts pricing at roughly $40,000 to $68,000 per year, with enterprise tiers reaching $90,000 or more, and Salesforce is a hard requirement (you can't use Qualified without it, which adds its own CRM cost). There's no outbound prospecting and no support capabilities; it's purely a sales qualification tool for your website.

Best for: Salesforce-centric enterprise teams with high website traffic and six-figure budgets for inbound conversion

#5 Amplemarket (Duo) — From $600/month (Startup, billed annually); Duo Copilot ~$3,200/user/year on annual terms

Amplemarket's Duo Copilot represents the human-in-the-loop school of AI SDRs, and it makes a compelling case. In Amplemarket's own 231-point capability comparison of eight platforms, Duo scored 221 out of 231 overall and a perfect 21 out of 21 in AI and automation, the highest tested. It's rated 4.6 out of 5 from 571+ reviews on G2. Duo works as three specialized agents. Signal monitors over 100 buying signals at the contact level, Research builds a per-prospect brief automatically, and Sequence drafts the multichannel campaign across seven channels. The rep approves in one click, or you move specific signals to autopilot within guardrails you set. Every approval trains the copilot to match that rep's voice over time, and Duo Inbox classifies and drafts replies. Because Duo sits on Amplemarket's full platform with native data, buying signals, and a complete deliverability suite, the workflow runs end to end without stitching together point tools. For agencies, this matters when your clients can't afford brand damage from unreviewed AI outreach. Amplemarket's own analysis argues that fully autonomous agents risk quality degradation and platform enforcement on social channels, and that buyers in 2026 increasingly filter out obviously automated messages. Pricing starts at $600/month for the Startup tier (billed annually), with Duo Copilot at roughly $3,200 per user per year on annual commitments.

Best for: SDR teams and agencies that want AI productivity without giving up human review and brand control
