After 4 months of building, I finally have something worth showing
Every marketing agency I've worked with has the same painful onboarding: chasing clients for a week to get access to their Google Ads, then Meta, then TikTok, then their CRM, then Shopify. Half the time, the client grants the wrong permissions. The other half, they never respond.
I built Joiyn (joiyn.ai) to solve exactly this.
The agency sends one link. The client clicks it, authorizes each platform in a single flow, and the agency instantly gets access to everything they need—Google Ads, Meta, TikTok, GA4, HubSpot, Shopify, GoHighLevel, and more—with no back-and-forth.
Joiyn currently supports 13 platforms. I shipped the GoHighLevel Marketplace integration last week, and the public listing is now under review.
I'm a solo developer offering a 7-day free trial with no credit card required. I'd genuinely love honest, brutal feedback from agency owners or anyone who's experienced the pain of client onboarding.
What's the worst client onboarding horror story you've seen?
What I found interesting is that the product isn't really reducing technical complexity.
It's reducing coordination complexity. A lot of operational friction comes from waiting on people rather than waiting on software, and solving that changes the experience in a very different way.
Exactly this and it took me a while to see it clearly. The technical part of connecting 15+ platforms is a solved problem. The unsolved part is the 3–5 days of Slack messages, screen-share calls, and “did you get the invite?” emails before a client actually clicks “Allow.”
That waiting-on-people cost is invisible in most agency P&Ls, but it’s the single biggest reason onboarding drags. Once you frame it as coordination debt instead of technical debt, the whole product shape changes—you stop building integrations and start building the shortest possible path from “send link” to “access granted.”
Appreciate you naming it that way.
Thanks for taking the time to explain your thinking. I'd enjoy continuing the conversation outside the thread if you're open to it. What's the best email to reach you on?
One-link access is clean. What’s the main use case right now — client delivery, internal tools, or something else?
Primary use case right now is agencies onboarding new clients just one link, the client clicks it, grants access to Meta, Google Ads, TikTok, GA4, Shopify, etc., and the agency sees the accounts appear in their dashboard. It replaces the usual “email me your login” or “add me as admin” back-and-forth.
The secondary use case is internal handoffs—when a client account moves between team members and you need a clean audit trail instead of shared passwords.
What are you working on? Curious if there’s a version of this problem in your world too.
Your two use cases (agency onboarding vs. internal handoffs) attract completely different buyers. The agency owner wants speed: "get me into 12 client accounts this week." The enterprise ops lead wants compliance: "I need an audit trail, SSO, and a data policy before I roll this out to 200 seats." Same product, opposite economics.
The risk: your "one link, no back-and-forth" messaging is pure agency positioning. It trains enterprise buyers to treat you as a "nice workflow tool" instead of "access governance infrastructure" — and that's a 10x LTV difference.
Quick test: ask new signups "Is this for client onboarding or internal team access?" Then track 14-day activation by answer. My guess: internal handoffs have 3x higher LTV but 5x lower signup volume because your site doesn't speak to them.
