Fuse AI - Build a Custom GTM Stack. One SDK. One MCP.
by•
Your GTM stack shouldn’t need a dozen tools, subscriptions, and APIs. Fuse gives developers and AI agents one SDK and MCP for the entire workflow. Think OpenRouter x Apollo x Clay x Zapier. Fuse takes care of web automations, data enrichment, multi-channel outreach, workflows, and AI agents. Build unlimited workflows and agents on top, without stitching together separate GTM products for every step.

Hey Product Hunt! 👋 Saurav here, co-founder of Fuse - I previously helped build GTM systems at Deel (YC 19) and quickly realized legacy GTM software was too clunky, rigid, and difficult for teams to manage.
Today, we’re launching one SDK and MCP to run your entire GTM stack. A new type of product for GTM teams, think OpenRouter meets Apollo meets Clay, but for GTM.
Your GTM stack shouldn’t need a dozen tools, subscriptions, and APIs.
We built Fuse to bring all of that together: 1,000+ applications, 40+ data providers, web scraping, AI research agents, managed multi-channel outreach infrastructure, workflows, AI context layer, and much more, accessible through one SDK and MCP.
With Fuse you can own custom GTM infrastructure in Claude, ChatGPT, Perplexity, and more, or embed Fuse directly into your application.
Here are a few things you can build:
🔎 An agent that finds your next customers: Find people and companies that match your ICP, enrich their emails and phone numbers through 40+ data providers, and sync qualified prospects to your CRM.
🧠 Your own GTM brain: Connect your business context to your agents so they can research accounts, qualify prospects, and tailor outreach around what matters to your company.
🌐 Your own AI research team: Build agents that scrape websites, research accounts, track company signals, and turn unstructured information into useful context for your sales team.
⚡ Multi-channel outreach on autopilot: Turn research into personalized email, LinkedIn, and power dialing sequences using managed outreach infrastructure.
🛠️ Custom GTM tools inside the AI products you already use: Build account research assistants, prospecting workflows, or a GTM command center tailored to your business.
Our goal is to give developers, sales professionals, and AI agents the infrastructure to build any GTM workflow they can imagine.
You bring the logic, your customer knowledge, and the ideas. Fuse handles the underlying infrastructure.
We’d love for you to try it and tell us what’s missing - feel free to text me anytime at 628-800-4934 for any product feedback or requests, we'll ensure we will prioritize it! :)
We’ll be here in the comments answering questions and helping you get started. 🚀

Fun Question: What’s the first thing you’d build if your entire GTM stack was available through one SDK and MCP?
@saurav_bubber2 the coustom GTM tools sound useful how easy is it to build your own workflow with fuse?
@shivam_kushwaha16 Very straight forward - you can leverage our automations layer to create custom automations or leverage our data / sending infrastructure and create your own automations in your CLI!
@saurav_bubber2 Yeah the custom workflow part is what makes this interesting being able to build automations around your own data is really useful
@saurav_bubber2 Combination of enrichment and research is interesting. Having better context before triggering an outreach action could make automated workflows much more useful.
Does it also handle marketing funnels or is it purely a sales tool?
@cloudalchemist Yep we handle marketing funnels as well!
As someone just starting out in this arena, I can see that this could be a HUGE help, both in execution in just keeping track of the sheer volume of details, tools, and targets! Congrats on the launch! I look forward to seeing what it can do!
@judy_bartlett Thank you - we work with teams of all sizes, no company is too small or too big!
@judy_bartlett thank you! There’s so much to juggle, especially when you’re starting out. Excited to hear what you think once you try it!
really cool, congrats!
Is this more for continuous GTM efforts, or does it also support apps such as PH too? I'm actually thinking of doing my own PH launch, and could definitely use some help with it lol.
interesting!
@sentineldigi Thank you! Would love to get your feedback on the platform.
MCP component strikes me as the most interesting aspect here. I believe it could be quite useful in enabling an AI agent to execute actual GTM actions or activities, rather than simply generating text.
Congrats 🎉 and what about LinkedIn outreach?
Can I review the messages before they’re sent?
Consolidating web automation, enrichment, outreach and workflows into one SDK and one MCP is appealing, since the usual GTM stack is a pile of subscriptions that never quite talk to each other. Letting agents drive the whole workflow from a single interface is the part that feels new. Does Fuse take care of rate limits and retries across the underlying providers?
@karimbenkeroum Yep, we handle rate limits and retries across the providers!
we're building the phone number side of agent outreach at Dial, so the "parallel dialing" line caught my eye. curious how you handle the compliance side once an agent is running multi-channel outbound on its own - opt-outs and do-not-call lists are per-channel today (unsubscribe on email, STOP on SMS, DNC registry on calls), does Fuse unify that so a lead who opts out on one channel is actually suppressed everywhere, or is that still on the team building on top of the SDK to wire up themselves
