Motion: Redefining How Work Gets Done

Motion began with a simple idea: help people manage their time better. After several pivots, the founders have built one of the fastest-growing work platforms, recently closing their Series B and C at a $550M valuation. Today, Motion is redefining how work gets done — not just managing projects, but embedding AI employees directly into the workflow. In this interview with YC General Partner Aaron Epstein, the founders share how they gave up seven-figure trading jobs to start from scratch, why they walked away from a successful consumer product, and how they’re building the platform where humans and AI work side by side.

WHAT IT’S REALLY ABOUT

Motion pivots from smart calendaring to AI-powered SMB work platform

  1. Motion sells an all-in-one work management suite (projects, docs, wikis, knowledge) to SMBs—especially service businesses across middle America.
  2. The founders left high-paying quant trading paths to “bet on themselves,” driven by competition, purpose, and a strong aversion to failure.
  3. After YC, Motion found early product-market fit with automated smart calendaring, quickly scaling to ~$1M ARR and later to the high-teens/near-$20M ARR range.
  4. They intentionally pivoted away from a prosumer productivity product because it lacked must-have retention dynamics and billion-dollar ARR potential, moving into B2B work management.
  5. Motion is now layering agentic capabilities (“AI employees”) on top of its platform, citing rapid early traction and the advantage of owning the customer’s workflow context and data.

IDEAS WORTH REMEMBERING

5 ideas

Early traction isn’t the same as a scalable path to a billion-dollar outcome.

Motion grew a prosumer calendaring product to roughly $15–$20M ARR, but concluded it was a “nice-to-have” with weaker retention dynamics than B2B, limiting long-term upside.

A hard pivot can be rational even after meaningful revenue success.

After an office hour warning that the category wouldn’t reach billion-ARR scale, they chose to restart with a new customer type and go-to-market, despite already having a profitable business.

B2B trust requires baseline parity plus a clear 10x differentiation.

They highlight that SMBs won’t adopt a new work platform without core features done well, and you still need one dimension where you are dramatically better to break through incumbents (Asana/Jira/Monday/Trello).

Owning the workflow system creates a compounding advantage for AI agents.

Motion argues their suite contains the projects, docs, knowledge, and task history that agents need for context, enabling stronger agent performance than standalone tools without embedded data.

The winning AI UX is integrated human+agent work, not separate tools.

They believe companies won’t manage “human tasks” and “agent tasks” in different systems because work handoffs require shared context and seamless transitions inside one platform.

We build work management software for small and medium-sized businesses… And what’s very exciting over last year is we have been building agents… we’re actually doing work for them.

— Motion team

As soon as we launched… automatic smart AI calendaring… it jumped to, like, a million ARR very quickly in… two months.

Michael was basically like, 'Yeah, you guys are fucked.'

— Motion team

It was pretty clear… there wasn’t really any purpose to what I was doing… Every day it was like, 'We’re gonna try to make money.'

The shame of… Motion not working out is just… too much to bear.
