Assembled attacks customer support from the operations side. Three ex-Stripe employees, brothers Ryan and John Wang and Brian Sze, watched support scale to thousands of people there and founded Assembled in 2018 to be the operating system for support teams: forecasting how much volume is coming, scheduling the right agents against it, and tracking whether the plan survived contact with reality. Stripe liked the idea enough to lead the seed round itself, and NEA led a $51 million Series B in 2022.
Workforce management is still the foundation, and the customer list is a who's who of scaled support: Stripe, Duolingo, Canva, Robinhood, Intuit, Etsy, and GoFundMe among them. But the platform's second act is Assist, an AI layer that resolves customer issues across voice, chat, and email and gives human agents a copilot. The combination is the pitch: one platform that staffs the humans correctly, manages the BPO vendors, and automates the conversations that never needed a person, with each side informing the other.
Unusually for this category, Assembled publishes its prices. Workforce management starts at $25 per agent per month, AI agents are priced per conversation from around $0.65, and AI voice can even be billed per resolution. A nice cultural note: part of the Series B funded CX Scholars, a program paying for support professionals' continued education.
Assembled makes sense once scheduling humans is genuinely hard, roughly when support headcount reaches dozens and shifts, channels, and vendors multiply. If you only want a bot, lighter tools exist; if you run a real support operation and want AI woven into the staffing plan rather than bolted beside it, Assembled is the standout.

Observe.AI made its name by fixing quality assurance, the least loved job in the contact center. Instead of a QA team sampling two percent of calls and arguing about scores, it transcribes and analyzes one hundred percent of interactions, scores them automatically against your rubrics, flags compliance risks, and turns the results into coaching. For support leaders it answers the questions that sampling never could: why are customers calling, which behaviors actually move CSAT, and which agents need help this week rather than at quarter end.
Founded in 2017 by Swapnil Jain and headquartered in Redwood City, the company raised a $125 million Series C led by SoftBank Vision Fund 2 in 2022, with Zoom as a strategic investor, and serves names like DoorDash, SoFi, Accolade, and Asurion. Like most of the conversation-intelligence category it has pushed aggressively into agents themselves: its VoiceAI agents now automate routine calls end to end, real-time assist guides live agents mid-conversation, and an Agent Harness handles the unglamorous work of testing and versioning AI agents before they meet customers.
The platform advertises more than 250 integrations across contact-center, CRM, and workforce systems, and pricing is custom, scoped to seat counts and interaction volume, with nothing published.
Observe.AI fits operations large enough that measuring conversations is a full-time problem: if you have dozens of agents or more and your QA process is a spreadsheet and good intentions, full-coverage automated scoring changes how you manage. Teams that just want a bot to deflect tickets have simpler options; teams that want to understand and improve every conversation, human or AI, should shortlist it.
