Stop Working For Free.

Agencies lose an average of $8,200/month to scope creep they never charge for. Parallel connects your SOW, your Linear board, and your invoices — so every hour your team works is an hour your client has already paid for.

The problem

Agency Math Is Broken.

You estimated 20 hours. Your team spent 40. The client paid for 20. That gap isn't bad luck — it's a broken system. Here's exactly where your margin is bleeding out:

THE TRAP01

The "Quick Favor" Trap

Requests arrive via Slack, email, and Zoom. Because it feels too tedious to draft a formal change order for a 2-hour task, your team just does it for free.

Slack Request
"Can we add login?"
+6h (~$600 Unpaid)
Email
"Change the colors quickly"
+3h (~$300 Unpaid)
BLIND SPOT02

The Disconnect

Your team lives in Linear, not in your SOW. They build whatever tickets are dragged into the current sprint, whether the client has officially paid for that feature or not.

Budget Cap
CASH FLOW03

The Approval Bottleneck

The work is finished, but the invoice is delayed because the client's "final approval" is buried somewhere in a 40-message email thread. Your cash flow stalls.

Our Story

We built Parallel because we were tired of working for free.

We're Stackk Studios— a software agency. And for years, we had the same problem every agency has: clients would Slack us "small" requests, we'd build them to keep the relationship warm, and nobody would ever send a change order.

One quarter, we sat down and counted. We had given away over $40,000 in untracked work across three projects. The clients were happy. We were not.

So we built Parallel — first for ourselves. We wired it into our Linear workflow, gave clients a portal to approve things, and made the AI handle the awkward "that's out of scope" conversation.

$2.4M. Recovered. By agencies just like ours.

When we opened Parallel to other agencies, they started recovering margin immediately. On average, agencies claw back $8,200/month in previously untracked scope. We've seen teams cut invoice-to-payment time by 60% in their first month.
