Three Stripe engineers got tired of watching support teams guess how many people to put on shift. So in 2018 they built Assembled to do the math. It forecasts how many customer questions are coming, then builds the schedule to cover them. Think of it as air traffic control for support agents. NEA led a $51 million round in 2022 that more than 5x'd the valuation in a single year.

Ryan Wang, John Wang, and Brian Sze all worked at Stripe. They watched the support team grow fast and hit the same wall every scaling company hits.
Nobody knew how many agents to put on shift. Too few and customers wait forever.
Too many and you burn money. The tools to figure it out were ancient call-center systems built for giant enterprises.
In 2018 the three of them left Stripe and started Assembled in San Francisco. They built modern workforce management for support teams that live in Slack and Zendesk, not old phone banks.
Their former employer Stripe ended up being an early backer.
WHAT THEY ACTUALLY DO
Assembled sells software to companies that run customer support teams. It does three jobs.
First it forecasts demand. It looks at your history and predicts how many chats, emails, and calls are coming next Tuesday at 2pm.
Second it schedules. It builds shift plans that match staff to that predicted demand.
Third it reports. Managers see in real time whether they are keeping up.
Companies pay a subscription based on how many agents they are managing. The pitch is blunt.
Stop over-staffing and stop making customers wait.
THE PRODUCTS
The flagship is the workforce management platform. It forecasts support volume, builds agent schedules, and tracks real-time performance against the plan.
Assembled has since added AI features that draft answers for agents and help resolve tickets faster. The through-line is the same.
Give support leaders a clear picture of demand and the tools to meet it without overspending on staff.
HOW THEY GREW
Assembled grew by landing exactly the kind of fast-scaling tech companies its founders came from. Stripe, Etsy, and other high-growth support teams became early customers.
These are companies that hire support agents by the hundreds and feel bad scheduling immediately. Word spread through the operations crowd.
The founders also leaned hard into public content, writing openly about support operations to pull in the exact managers who would buy. By 2022 the Series B valued the company at more than 5x its Series A price from a year earlier.
THE HARD PART
Workforce management can be a feature, not a whole company. The big support platforms like Zendesk and Intercom can build scheduling right into their own tools.
Assembled has to stay far enough ahead that teams pay for a separate product. The bigger question is AI.
If AI agents handle more support tickets, companies need fewer human agents to schedule in the first place. Assembled has responded by building its own AI support features.
But the core business was built on managing people, and that pool could shrink.
MONEY TRAIL
Series A
2021 · Led by Emergence Capital
$17M raised
Series B
2022 · Led by New Enterprise Associates
$51M raised
WHO BACKED THEM
The founders' Stripe roots opened doors. Stripe itself was an early backer.
Emergence Capital led the $16.6 million Series A in 2021. New Enterprise Associates led the $51 million Series B in 2022, with Emergence and Basis Set Ventures joining again.
That brought total funding to roughly $70.7 million. NEA leading the Series B was the signal that Assembled had grown past a niche tool into a real platform bet.

Companies
Stripe
All three Assembled founders came out of Stripe, where they felt the pain of scaling a support team. Stripe later backed the company as an early investor.
Zendesk
Zendesk is where many of Assembled's customers run their support. It is both a key integration partner and a giant that could build scheduling into its own product.
