Ergo — AI Co-pilot for Modern Revenue Teams

YC W25 · San Francisco

Our Mission

To free every sales team from busywork so they can focus on what matters: building relationships and closing deals. Ergo turns unstructured conversations across platforms like Zoom, email, Slack, and phone into clean CRM data, proactive follow-ups, and real-time insights—automatically.

"Ergo takes care of the busywork so I can focus on selling and building relationships. It keeps everything moving without anything slipping through the cracks."

Connor Quimby Senior Account Executive, Rho

What We Do

  • AI Co-Pilot for Sales that listens to calls, emails, and chats: 10+ hrs/week reclaimed per rep
  • Autonomous CRM updates: Remove data incompleteness or quality issues by eliminating manual entry.
  • Proactive follow-up emails surfaced exactly at the right time to nudge deals: 10%+ lift in win rates and faster deal cycles
  • Real-time insights & revenue reporting: Actionable coaching and data-driven decisions

Some of the fastest-growing companies like Rho, Delve, Whop, Sully.ai, and Greptile trust Ergo to help their revenue engines scale.

"Ergo is the best product we’ve used this year. Besides saving reps 10h per week, it unlocks new revenue and teaches reps how to improve with proactive insights.”

Karun Kaushik Co-founder and CEO, Delve

About Ergo

Ergo turns every customer conversation—across Zoom, email, Slack, and phone—into structured CRM data, proactive follow-ups, and real-time revenue insights. We free sales teams from busywork so they can focus on relationships and closing deals.


Why This Role Exists

We’ve proven product–market fit with early reference customers and are now scaling our platform to handle massive data volumes and increasingly complex AI-driven workflows. As our next Backend Engineer, you’ll be building the infrastructure and systems that make Ergo fast, reliable, and capable of serving thousands of users in real time.


What You’ll Tackle

Scaling Core Services: Architect and scale ingestion pipelines and APIs to handle millions of daily events across calls, emails, and messages.

System Reliability & Performance: Design robust distributed systems that ensure uptime, resilience, and sub-second response times.

Data & AI Workflows: Build infrastructure for advanced AI agents that handle sales tasks—like CRM updates, follow-ups, and insights—across diverse customer setups.

Integrations: Develop deep integrations with CRMs, communication tools, and productivity platforms.

Collaboration & Product Impact: Work directly with founders and customers to scope features, gather feedback, and iterate quickly.


You Might Be a Fit If You

  • Bring 1+ years of experience building and scaling production-grade backend systems.
  • Have strong proficiency in Node.js and/or Python.
  • Are comfortable designing APIs and working with distributed systems.
  • Are interested in real-time data processing, AI workflows, and large-scale ingestion challenges.
  • Thrive in ambiguity, bias toward action, and enjoy building from zero to one.
  • Communicate clearly and collaborate well with both technical and non-technical teammates.
  • Love learning fast and picking up new tools, frameworks, or approaches as needed.

You Might Not Be a Fit If You

  • Are looking for a 9–5: the team typically works all day with breaks, meals, and exercise; it’s common to work into the night.
  • Need extensive handholding: everyone on the team is doing critical work; high agency is valued.
  • Aren’t comfortable optimizing for speed: sometimes this means creative, hacky, or messy solutions.
  • Don’t like working closely with others: we collaborate constantly, giving and receiving feedback in real time.
  • Are uncomfortable working with a young, high-velocity team.

Nice-to-Haves

  • Experience with real-time data pipelines or high-volume ingestion systems.
  • Familiarity with CRM, RevOps, or sales tooling integrations.
  • Exposure to AI systems, LLMs, or retrieval-augmented generation (RAG).

Compensation & Benefits

  • Competitive salary plus meaningful equity.
  • Executive membership at the Bayclubs.
