If you are evaluating AiSDR vs Salesforge right now, you have probably already seen the marketing. Both call themselves AI SDRs. Both promise autonomous outbound. Both have slick dashboards that make you feel like you are about to automate your entire pipeline. But here is what nobody tells you: the way these tools actually work under the hood is wildly different, and picking the wrong one will cost you months and thousands of dollars.
I have spent the last two years watching teams try both. Some crushed it. Most did not. Let me walk you through what actually matters when you are choosing between these two, and then I will show you a third option that solves problems neither of them addresses well.
What AiSDR and Salesforge Actually Do
Before we compare, let us be clear about what each tool is built for.
AiSDR positions itself as a targeted AI sales agent. The pitch is that you feed it your website, it builds your go-to-market strategy, creates your ICP, writes your messaging, and runs multichannel campaigns across email, LinkedIn, calls, text, video, and voice notes. It has an AI Strategist called Ami that supposedly designs campaigns from scratch in about 20 minutes. They also emphasize signal-based targeting, meaning the system looks at LinkedIn engagement, funding rounds, hiring signals, and website visitors to build prospect lists dynamically.
Salesforge takes a different approach. Their flagship product is Agent Frank, an autonomous AI SDR that focuses primarily on cold email at scale. You define your ICP, upload a knowledge base with your pitch docs and brochures, and Agent Frank prospects, writes, sequences, and sends. The philosophy here is modular: keep everything cheap, let teams plug Agent Frank into their existing infrastructure, and stay DIY.
Both are legitimate tools. But the devil is in the details.
AiSDR vs Salesforge: Pricing Reality Check
Let me tell you this: pricing is where most teams get surprised.
AiSDR starts at around $250 per month for their Solo tier with approximately 200 contacts. But most outbound teams end up paying $900 per month and up. Higher tiers reach $2,500 plus monthly. No true free plan. No standard free trial. And multiple sources report a 30 to 60 day ramp before you see meaningful results. That means you are potentially paying $1,800 to $5,000 before you even know if the thing works for your use case.
Salesforge is significantly cheaper. The platform itself runs about $40 per month at the Pro level. Agent Frank starts at $499 per month on annual billing, roughly $599 if you pay quarterly, for about 1,000 active contacts. Email infrastructure through Infraforge is around $33 per month for multiple mailboxes. They offer a 14-day trial for Agent Frank in some cases.
The math here is straightforward. If you are a small team testing AI outbound, Salesforge gets you in the door for a fraction of AiSDR’s cost. If you are a funded startup with budget and need strategy help baked in, AiSDR’s higher price might make sense. Maybe.
Channel Coverage: Where Each Tool Excels
This is where the comparison gets interesting.
AiSDR does multichannel. Email is core, but they also support LinkedIn outreach with connection requests and messages, calls and dialer-style workflows in higher tiers, plus text, SMS, video, and voice notes in sequences. If you want to hit prospects across multiple touchpoints from one platform, AiSDR has broader coverage.
Salesforge is email-first. Agent Frank is built to dominate cold email. They have a massive contact database with over 500 million contacts for prospecting. But multichannel beyond email is less emphasized. If LinkedIn automation or calls are critical to your outreach motion, Salesforge is not your answer.
Here is the thing though. Having features listed on a pricing page and having features that actually work well are two different things. I have talked to teams who tried AiSDR’s LinkedIn functionality and found it clunky compared to dedicated LinkedIn automation tools. The jack-of-all-trades approach sometimes means master of none.
AI Engine and Automation Depth
Both tools claim AI. But what does that actually mean?
AiSDR’s AI Strategist (Ami) reads your website and supposedly builds GTM campaigns from scratch. It handles lead qualification and post-booking nurturing through an AI conversation engine. Their signal-based targeting pulls LinkedIn engagement, funding data, hiring signals, and website visitors to build lists dynamically rather than relying on static databases.
Salesforge’s Agent Frank operates from your defined ICP and knowledge base. Once configured, it can run fully autonomously. But they also have a Co-Pilot mode where you review and approve each message before sending. The AI conversation engine focuses primarily on email copywriting and sequence optimization rather than broad strategy.
In practice, AiSDR gives you more strategic hand-holding. Salesforge gives you more control. Neither truly replaces human judgment on complex deals.
Data Sources and Prospecting
Where do the leads come from?
AiSDR uses what they call live AI search. Instead of relying solely on static contact databases, the system pulls prospects on demand based on signals. The idea is fresher, more relevant data.
Salesforge leans on their 500 million plus contact database. Prospecting revolves around this large but static pool. The upside is volume. The downside is data decay. Contact databases get stale fast.
Neither approach is perfect. Live search can be slower and more expensive per lead. Static databases give you scale but require constant enrichment. For teams doing serious outbound, pairing either tool with dedicated B2B data enrichment tools is usually necessary.
Stack Design and Integrations
How do these tools fit into your existing setup?
AiSDR bundles domains, mailboxes, warmup, and sometimes LinkedIn allowances into a single contract. They often sell with onboarding and a managed service layer where their team helps set up and optimize campaigns. One invoice, less control.
Salesforge separates platform subscription, email infrastructure, and Agent Frank. They encourage you to treat it as one part of a broader stack. More DIY, more control over proxies, domains, and CRM sync. If you like building your own systems, this approach works. If you want someone else to handle everything, it does not.
LinkedIn Account Safety: The Hidden Risk
Here is something most comparison articles skip entirely.
If you are running LinkedIn automation, account safety is everything. Get it wrong and LinkedIn restricts or bans your profile. I have seen teams lose months of relationship-building because they pushed too hard with the wrong tool.
AiSDR includes LinkedIn in their multichannel sequences, but the safety mechanisms are not their core focus. They are primarily an email tool that added LinkedIn.
Salesforge does not emphasize LinkedIn at all. Agent Frank is built for email.
Neither tool specializes in keeping LinkedIn accounts safe at scale. If LinkedIn is a primary channel for you, and for B2B it often should be, this is a gap.
Support and Onboarding
AiSDR leans heavily into onboarding support. They position themselves as a managed service where their team actively helps set up and optimize campaigns. For teams without outbound experience, this hand-holding can be valuable. For experienced teams, it can feel slow and prescriptive.
Salesforge is more self-serve. You get documentation, a trial period, and you figure it out. Some teams love this. Others struggle without guidance.
Neither is universally better. It depends on your team’s experience level and how much support you actually need.
What Both AiSDR and Salesforge Miss
Okay, here is where I have to be honest about what neither tool does well.
Real chat automation. Both tools send messages. Neither one truly handles the conversation after a prospect replies. They sequence outreach. They do not hold conversations.
Think about it. You send 1,000 cold emails or LinkedIn messages. Maybe 50 people respond. Now what? With AiSDR or Salesforge, you or your team manually handles every reply. You are still doing the work. The AI stopped at the send button.
This is the gap that kept bothering us.
Why SBL.so Beats Both for LinkedIn-Heavy Teams
Full disclosure: I am going to talk about SBL.so now because it solves problems that AiSDR and Salesforge do not address.
SBL is built specifically for teams that need LinkedIn outreach with actual AI conversation handling. Not just sending. Chatting. Persuading. Booking calls.
Here is what makes it different:
Persuasion Chat Model. When a prospect replies, SBL’s AI takes over the conversation. It keeps the chat going, handles objections, asks qualifying questions, and pushes toward your goal. If your goal is booking calls, it guides them there. If it is qualifying, it asks the right questions. You can monitor every chat in your dashboard and jump in anytime, but the AI handles the heavy lifting.
Human Intervention When Needed. The system knows its limits. If it cannot handle a query, it flags it as Human Intervention Required. You step in for those specific chats. The AI learns from your responses and handles similar queries automatically next time.
Unlimited Sender Profiles and Account Rotation. Connect unlimited LinkedIn accounts to one workspace. SBL rotates profiles automatically so when one hits LinkedIn’s limit, the next takes over. This is how you achieve up to 75 new connections per day and 200 messages to first-degree leads per day. Safely. No other platform does that without getting accounts banned.
Fractional SDR Profile Network. Do not have enough accounts to scale? SBL has built a community of verified LinkedIn users who can run outreach for you as affiliates. Real profiles, not bots. Starting at $65 per month per profile.
Unified Inbox. All your chats from all connected LinkedIn accounts appear in one central inbox. Assign teammates to the same workspace. No more switching between accounts.
LinkedIn + WhatsApp. SBL works across both channels, so you can follow the same lead without losing context or tone.
The pricing starts at $99 per month with a free trial. Compare that to AiSDR’s $900 plus or even Salesforge’s $499 for Agent Frank.
AiSDR vs Salesforge vs SBL: Head-to-Head
Let me break this down simply.
Choose AiSDR if: You have budget for $900 plus monthly. You need multichannel sequences across email, LinkedIn, calls, and SMS. You want strategy help baked in. You are okay with a 30 to 60 day ramp before results.
Choose Salesforge if: You want cheaper entry at $499 per month for Agent Frank. You care primarily about cold email at scale. You prefer DIY control over your infrastructure. LinkedIn is not a major channel for you.
Choose SBL if: LinkedIn is a primary outreach channel. You need AI that actually handles conversations, not just sends messages. You want to scale LinkedIn outreach at email-level volume without getting accounts banned. You need sales automation for small teams that does not require a massive budget.
Common Questions About AiSDR vs Salesforge
Which is cheaper: AiSDR or Salesforge?
Salesforge. Their modular stack starts much lower in monthly cost. AiSDR bundles everything into higher-priced contact-volume tiers.
Which is better for multichannel outbound?
AiSDR covers more channels including LinkedIn, calls, text, video, and voice notes. Salesforge focuses on email.
Does AiSDR replace a human SDR team?
Partially. It can handle prospecting, messaging, and follow-up. But complex deal work and strategy still need humans. Same is true for Salesforge.
How autonomous is Salesforge’s Agent Frank?
Fully autonomous once ICP and knowledge base are configured. But there is a Co-Pilot mode if you want to approve each message before sending.
Do either offer a free trial?
Salesforge offers a 14-day trial for Agent Frank. AiSDR typically does not have a standard free trial and uses sales-led onboarding.
What about LinkedIn safety?
Neither tool specializes in LinkedIn account safety. If you are scaling LinkedIn outreach, dedicated tools like SBL with built-in account rotation and safety limits are safer bets.
The Verdict
AiSDR and Salesforge are both legitimate AI SDR tools. AiSDR is the expensive, strategy-heavy, multichannel option. Salesforge is the affordable, email-first, modular option.
But if LinkedIn matters to your outreach, and you want AI that actually talks to your prospects instead of just messaging them, neither one is the right fit. That is where SBL comes in.
We have been building SBL since 2023, quietly testing it in real campaigns. It is not another sequence tool with AI slapped on the label. It is built to handle the full conversation lifecycle on LinkedIn. Connection, message, reply, objection handling, qualification, booking. All of it.
