Quick honest summary
11x builds a specialized AI SDR called "Alice" that handles outbound prospecting: finding prospects, writing sequences, and booking meetings. They also offer "Julian," an AI phone agent for inbound qualification and outbound calling. If your only AI priority is automating outbound SDR volume, 11x is purpose-built for that.
Nexus is a different category. It is a platform and service for building autonomous AI agents across any department: sales, support, marketing, HR, operations, compliance. Not a pre-built agent for one use case, but a foundation where your business teams build the exact agents they need for any workflow, connected to 4,000+ enterprise systems, with Forward Deployed Engineers embedded alongside your team to ensure the deployment succeeds.
The distinction matters. 11x is a sales tool. Nexus is an enterprise AI transformation solution: platform plus white-glove service. The right choice depends on whether you need to automate one outbound workflow or transform how work gets done across your organization.

When 11x is the better choice
11x is the right fit in specific scenarios, and it is worth being honest about that:
-
Outbound SDR is genuinely your only AI priority. If the single biggest bottleneck in your organization is outbound prospecting volume, and you have no plans to automate other workflows, 11x is purpose-built for that exact problem. It does one thing, and its focus on that single use case is a real advantage for teams with narrow requirements.
-
You want a plug-and-play SDR agent with minimal setup. 11x is a pre-built product. You configure "Alice," define your ICP, and it starts prospecting. If speed-to-first-meeting is the only metric that matters, this simplicity is a genuine advantage over building a custom agent from scratch.
-
Your sales team needs volume, not depth. If your go-to-market motion is high-volume outbound and you need an AI that works through prospect lists and writes sequences, 11x is designed for that workflow. Be aware that reviews are polarized on personalization quality, so evaluate carefully whether the output meets your standards before committing to an annual contract.
-
You are a sales-led organization and AI adoption starts and ends with SDR. If your organization is not ready for a platform approach and you want to prove AI value in one specific function with no plans to expand, 11x gives you that focused starting point.
When Nexus is the better choice
Enterprises that partner with Nexus share a specific pattern: they need AI that works across the organization, not just in one department. And they need more than software. They need a partner who embeds with their team to make deployment succeed.
-
Outbound is one of many workflows you need to automate. Most enterprises do not have a single AI problem. They have dozens: customer onboarding, sales intelligence, support triage, compliance monitoring, HR operations, proposal generation. If outbound SDR is one priority among many, you need a platform that handles all of them, not a separate vendor for each one. Companies we work with build 3, 5, even a dozen agents on the same foundation.
-
You need sales intelligence, not just sales outreach. 11x automates the act of reaching out. But what about the intelligence behind the outreach? Monitoring thousands of accounts for buying signals, competitive movements, leadership changes, funding rounds. The deep research that makes outreach actually effective. That is a different capability entirely, and it is what Lambda built on Nexus: 12,000+ enterprise accounts analyzed with deep intelligence, $4B+ in pipeline identified that manual analysis would have missed.
-
You need deployment support, not just software. Deploying AI at scale is 10% technology and 90% organizational change. Nexus embeds Forward Deployed Engineers with your team to identify the highest-impact use cases, design agents for your specific reality, handle integration complexity, and run pilots without requiring your internal resources. Most enterprise AI vendors sell software and disappear. With Nexus, you get engineers who stay until the deployment delivers measurable outcomes.
-
Your business teams need to own the AI, not depend on a vendor's product decisions. With 11x, you use their agent, configured within their parameters. If your outbound process does not match their template, you adapt your process to fit their tool, or you wait for them to add the feature you need. With Nexus, your business teams build agents tailored to exactly how your organization works. Lambda's Head of Sales Intelligence, who has no engineering background, built their first agent in days. He did not configure someone else's product. He built an agent tailored to how Lambda actually does sales intelligence.
-
You need agents that work across multiple systems, not just sales tools. If the workflows you are automating span CRMs, ERPs, communication platforms, ticketing systems, and custom APIs, 11x cannot reach them. Even workflow automation tools that connect many apps break on exceptions and judgment calls. Nexus connects to 4,000+ enterprise systems and deploys agents across any channel: Slack, Teams, WhatsApp, email, phone, web.
-
You need enterprise-grade governance from day one. SOC 2 Type II, ISO 27001, ISO 42001, GDPR. Full audit trails, decision traceability, role-based access. Every agent decision is traceable: what data informed it, which rules applied, why it escalated or approved. For enterprises where compliance is a requirement, not an afterthought, this matters.
-
You want a foundation that compounds, not a tool that stays narrow. For a deeper look at the build-vs-buy decision, see our enterprise analysis. Every agent you build on Nexus makes the platform more valuable. The integrations, the institutional knowledge, the deployment infrastructure: it all compounds. Lambda started with one sales intelligence agent. Now they are building an agent fleet across sales and marketing, with anticipated value exceeding $7M by 2026. A single-use tool stays exactly what it is.
What enterprises experienced
Lambda: from single agent to agent fleet across sales and marketing
Lambda, a $4B+ AI company with world-class engineers, could have bought individual single-use tools for each sales workflow or built custom agents internally. Instead, they chose a platform approach. Their CTO concluded that the opportunity cost of engineering time was too high, and buying separate point solutions for each workflow would create fragmentation rather than a foundation.
They chose Nexus. Joaquin Paz, Lambda's Head of Sales Intelligence (who has no engineering background), built their first agent on Nexus in days. That agent, AMO Enterprise Evolution, now monitors 12,000+ enterprise accounts for buying signals, competitive movements, and market opportunities. It delivers 24,000+ hours of research capacity annually (equivalent to 12 full-time analysts) and has identified $4B+ in cumulative pipeline that manual analysis would have missed.
What matters for this comparison: Lambda did not stop at one agent. They are now building an agent fleet. Additional deep research agents for stakeholder mapping and competitive positioning. Marketing operations agents for campaign automation and event management. All on the same foundation. The anticipated value: more than $7M by 2026.
In Joaquin's words: "We looked at open-ended AI agents; they were smart but inconsistent. Same question, different answer every time. We looked at traditional automation; it was reliable but felt heavy, lots of hard coding. With Nexus, we got both: intelligent and consistent."
On building without engineering: "I am not an engineer. I built this in days. With the automation tools we looked at before, I would have needed to spec everything out and wait months for development."
That is the difference between a single-use tool and a platform with embedded engineering support. One agent became many. One department became several. The foundation they built for the first agent became the infrastructure for everything that followed.
A European consulting firm (400+ employees): 5 agents across the consulting lifecycle
A European consulting firm did not need an AI SDR. They needed AI across their entire consulting lifecycle. On Nexus, they built five agents:
- Interview Agent autonomously conducts candidate interviews and provides structured assessments
- CV Generator takes recordings and LinkedIn profiles, generates standardized consultant CVs
- Project Matchmaker compares consultant experience to project requirements, generates optimized bios
- Proposal Copilot analyzes client requirements, pulls past experience, generates full proposals
- HR Agent answers employee questions via email, troubleshoots issues, escalates when needed
Proposal turnaround went from days to hours. Tens of thousands of hours freed monthly. The firm did not buy five separate AI products for five separate use cases. They built five agents on one platform, with Forward Deployed Engineers guiding the deployment.
This is the pattern single-use AI tools cannot match. Real enterprises do not have one workflow to automate. They have many. And they need a foundation, plus the deployment expertise, that handles all of them.
Key differences explained
Single-use tool vs. enterprise platform: the category question
This is the fundamental distinction, and it matters more than any feature comparison.
11x is a product. It does outbound SDR. When you also need to automate customer onboarding, sales intelligence, support triage, compliance monitoring, or proposal generation, you need a different product. And then another. Each one is a separate vendor, a separate integration, a separate contract, a separate learning curve. Your AI spend grows linearly with every workflow you add.
Nexus is a platform. You build the agent you need for any workflow, in any department. Orange built customer onboarding agents. A European consulting firm built 5 agents across their consulting lifecycle. Lambda is building an agent fleet across sales and marketing. All on the same foundation, all connected to the same enterprise systems, all owned by the business teams who understand the work.
The question is not whether 11x is good at outbound SDR. It is whether outbound SDR is the only thing you will ever need AI to do. For most enterprises, the answer is no.
Software vs. solution: why the service layer matters
This is the difference most comparison pages miss.
11x sells software. You configure their product, and you are on your own to make it work within your organization. Nexus is a solution: platform plus service. Every enterprise engagement includes Forward Deployed Engineers who embed with your team, not just to handle technical integration, but to identify the highest-impact use cases, design agents for your specific workflows, manage organizational change, and continuously optimize performance.
Why does this matter? Because deploying AI at scale is 10% technology and 90% organizational change. The enterprises that succeed with AI are not the ones with the best tools. They are the ones with the best deployment approach. Nexus has a 100% POC-to-contract conversion rate because every engagement starts with engineers embedded alongside your team, ensuring the deployment delivers measurable outcomes before you commit.
Lambda did not just buy software. They got a deployment partner. Joaquin built the agent, and the Nexus team ensured it integrated seamlessly with Lambda's systems and scaled across their go-to-market organization.
Pre-built product vs. agents you own
With 11x, you are configuring someone else's agent within their parameters. The agent works the way 11x designed it to work. When your process does not match their template, you adapt your process to fit their tool, or you wait for them to build the feature you need. You are dependent on their product roadmap.
With Nexus, your business teams build agents that match exactly how your organization operates. No engineering dependency. No vendor roadmap dependency. The agent adapts to your process, not the other way around. When requirements change (and they always change), you modify the agent yourself.
Platform economics vs. point solution economics
Single-use tools have linear economics. Each new use case requires a new tool, a new vendor, a new cost center. Your AI spend grows proportionally with every workflow you automate.
Platform economics work differently. The integrations you set up for the first agent serve every subsequent agent. The institutional knowledge compounds. The infrastructure investment amortizes across every use case. Lambda's first agent became the foundation for their entire agent fleet. Each new agent deploys in days and makes the whole system more capable.
For enterprises thinking about AI transformation at scale, this distinction is significant. A portfolio of point solutions does not become a platform. A platform becomes whatever you need it to be.
Frequently asked questions
Can I use 11x for outbound and Nexus for everything else?
You can, but most enterprises find it simpler to consolidate. If you are building agents on Nexus for other workflows anyway, building your sales agents on the same platform gives you a unified foundation: shared integrations, shared data, shared institutional knowledge. That said, if 11x is already working for your SDR team and you are happy with the results, there is no reason you cannot run both.
We only need outbound SDR automation right now. Why would we choose Nexus?
If outbound SDR is genuinely your only AI priority, now and in the foreseeable future, 11x might be the simpler choice. But most enterprises we talk to start with one use case and quickly identify five more. If there is any chance you will want to automate other workflows within the next 12 months, starting on a platform gives you a foundation to build on. Starting on a point solution means starting over when you are ready to expand.
How does Nexus handle outbound sales use cases?
Companies we work with build sales agents on Nexus that go beyond basic outbound. Lambda built deep research agents that monitor 12,000+ enterprise accounts, identify buying signals, and deliver intelligence that makes outreach actually effective. The difference is scope: not just sending emails, but understanding the accounts you are reaching out to, prioritizing based on real signals, and connecting sales intelligence to the rest of your go-to-market operation.
How long does it take to deploy a Nexus agent?
Most enterprise POCs go live within 2 to 6 weeks, with a Forward Deployed Engineer handling integration and configuration alongside your team. Lambda's first agent was in production within 4 weeks. Orange deployed customer onboarding agents in 4 weeks. The European consulting firm built five agents across their consulting lifecycle. Every engagement starts with a 3-month proof of concept tied to measurable outcomes.
What if we are not sure what to automate beyond outbound?
That is normal. Most enterprises know they need AI to do more, but they are not sure where to start beyond the obvious use case. Every Nexus engagement includes a Forward Deployed Engineer who works alongside your team to identify high-impact workflows across departments. Lambda started with one sales intelligence agent. Now they are building across sales and marketing. The platform and the FDE team help you discover what is possible, not just deliver what you already planned.
What is a Forward Deployed Engineer?
A Forward Deployed Engineer (FDE) is a real engineer from Nexus who embeds with your team during deployment. FDEs are not customer success managers reading from a playbook. They are engineers who understand your business, design agents for your specific workflows, handle integration complexity, and ensure the deployment delivers measurable outcomes. This is the service layer that separates Nexus from tools that sell software and disappear.
How does Nexus compare on contract flexibility?
Every Nexus engagement starts with a 3-month proof of concept tied to specific, measurable outcomes. You see results before committing to anything longer. If the POC does not deliver, you walk away. This is different from platforms that require annual commitments upfront before you have seen any results.
Worth exploring?
If outbound SDR automation is one of several workflows you are looking to transform with AI, it might be worth seeing how Lambda went from a single sales intelligence agent to an agent fleet anticipating more than $7M in value, or how a European consulting firm built 5 agents across their entire consulting lifecycle on one platform, each with Forward Deployed Engineers guiding the deployment.
Every engagement starts with a 3-month proof of concept tied to specific outcomes. You can exit anytime.
