# Customer Engineer at RevenueBase Inc

- **Company:** RevenueBase Inc
- **Location:** Waltham, MA
- **Employment:** full-time
- **Work type:** remote
- **Posted:** 2026-04-24
- **Last confirmed live:** 2026-10-19
- **Apply:** https://jobs.ashbyhq.com/revenuebase-inc/d2413e75-9cf9-47d3-933d-b3e94898e3f6

## Job description

RevenueBase:

- We're building the data infrastructure that makes AI agents trustworthy instead of error-prone.
- We provide continuously refreshed, verified B2B data for autonomous AI agents and GTM workflows.
- We've tripled growth while maintaining 100% gross dollar retention and staying cashflow positive.
- We power AI agents for Clay, Zoominfo, Dun & Bradstreet, and the next generation of AI GTM tools.

Why We're Hiring This Role:

- The companies building the future of go-to-market are building on top of our B2B data infrastructure. Many are onboarded and running.
- The hardest part of being a B2B data customer is figuring out how to run the right searches across the data to get the business outcome they bought us for. They need a technical partner to help them actually succeed with the product.
- This role exists to own the full customer lifecycle — onboarding, activation, health, and expansion — across every account we have.
- You are the founding hire for this function. When we hire behind you, you hire them.

What You'll Do:

- Own the "first successful search" — every new customer's activation milestone. Get them there, fast. This is the most important thing you do.
- Own customer health across all accounts. Know which customers are getting value, which are quiet, and which are at risk — before anyone asks.
- Drive expansion and cross-sell. As we ship new API surface area (verification, enrichment, discovery, MCP), identify which customers need what and run the expansion conversation.
- Run onboarding at scale. 3-5 new customers per month today, scaling to 10+. Make onboarding light, fast, and reliably successful.
- Be the voice of the customer inside RevenueBase. Sit on top of every Slack channel, every support request, every integration conversation, and tell product and engineering what customers actually need.
- Build the function. Write the playbooks, the health scoring, the expansion motion, and the onboarding framework — then rewrite them when they stop working.

Who You Are:

- You've owned a quota before — NRR, expansion, or retention — and know how to drive it without being pushy.
- You've worked at early-stage companies. You are allergic to process for process's sake. You write the playbook because there isn't one.
- You are the most technical non-developer in every room, and developers respect you. You don't pretend to be an engineer, but you're not precious about getting into the weeds.
- You don't wait to be told. The customer's success is your outcome, and you treat it that way.

Must have:

- Tech literacy — enough to read a customer's integration code (Python, JSON, SQL, you name it), spot what's broken, write a small script to demonstrate an API call, and be credible in a technical conversation.
- B2B data fluency — you know what firmographics, technographics, intent, and contact enrichment are. You understand why an email bounces, why a company name match is hard, and why verification matters.
- API mental model — REST, webhooks, rate limits, authentication, and the difference between a batch file drop and a real-time API call. You can walk a customer through integrating our MCP server.

Nice to have:

- Direct experience in B2B data, sales intelligence, or RevOps tooling
- Experience with MCP servers or LLM-powered agent workflows
- Prior founding CS or founding CE experience at an early-stage company

Your First 90 Days:

- Days 1-30: Shadow every active customer conversation. Write queries against our Snowflake environment. Sit in on sales and onboarding calls. Build a map of all customers — health, usage, expansion potential, risk.
- Days 31-60: Take ownership of onboarding. Run the "first successful search" milestone with every new customer. Publish a customer health scoring framework.
- Days 61-90: Identify and execute your first three expansion opportunities. Ship the v1 onboarding playbook. Tell us what you need to do this job 10x better.

Who You Are Not:

- You have not spent your career at companies with 1,000+ employees and defined CS processes.
- You do not need a playbook to get started.
- You are not looking for a pure relationship role with no technical depth, and you are not looking for a pure engineering role with no customer contact.

Why RevenueBase:

- Product with real traction: Customers rely on our platform in production.
- High ownership: Small team where your work directly shapes the product.
- Customer-driven culture: Activation and retention are how we measure success.
- Growth stage company: Clear product-market fit and momentum.
- Impact over process: Less bureaucracy, more building.

What We Offer:

- Competitive compensation based on experience.
- Meaningful ownership and long-term growth opportunities.
- Flexible working hours.
- Fully remote-friendly team (East Coast / Boston preferred).
- Direct collaboration with founders and core engineering leadership.

## About RevenueBase Inc

## Company Overview
- **One-liner**: RevenueBase builds B2B data infrastructure — a platform of continuously verified contacts and companies delivered through flat-rate feeds and per-outcome APIs, designed for GTM teams, AI agents, and embedded products.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: Waltham, Massachusetts, USA
- **Founded**: May 1, 2021
- **Founders**: Mark J. Feldman, Milenko Beslic

## Core Business
- **Primary Industry**: B2B Data Infrastructure / Data as a Service
- **Target Customers**: GTM product companies (embedding data into their SaaS), enterprise sales & marketing teams, demand generation agencies, AI developers, and data providers.
- **Mission**: To build the foundational data layer for B2B go-to-market — verified, always-current, and designed for modern GTM programs, AI agents, and data-driven products. [revenuebase.ai](https://revenuebase.ai/company)

## Products & Services
- **Data Feeds**: Flat-rate, unlimited access to 390M+ continuously verified B2B contacts and 60M+ companies, delivered directly to Snowflake, S3, and cloud storage. Records are re-verified every 90 days (contacts) and 60 days (emails), with 30M+ daily verification signals.
- **Clean & Enrich APIs**: Per-outcome pricing for canonical ID matching, stale job updates, missing field fills (revenue, title), and email verification at 97%+ accuracy, including catch-all domain resolution.
- **Discover & Search APIs**: Natural language and semantic search (e.g., "car dealerships" instead of SIC codes) with per-outcome pricing.
- **Gigasheet (No-Code UI)**: A browser-based interface for teams that don't need technical integration, enabling data exploration and export without APIs.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed.
- **Total Funding**: Seed round closed on April 6, 2022. Amount not publicly disclosed. [crunchbase.com](https://www.crunchbase.com/organization/revenuebase)
- **Key Metric**: 390M+ contacts, 60M+ companies, 1B+ monthly verification signals processed.
- **Notable Customers/Partners**: ZoomInfo, Dun & Bradstreet, Clay, Wiza. [revenuebase.ai](https://revenuebase.ai/company)
- **Growth Signals**: 11 total employees (per Built In), actively hiring across engineering, customer engineering, and sales roles. Customer outcomes include bounce rates reduced from 30%+ to under 2% and $900K+ pipeline generated for individual accounts. [builtin.com](https://builtin.com/company/revenuebase)

## Competitive Advantages
- **Pricing Model**: Flat-rate feeds and per-outcome APIs (pay only for verified results) vs. the industry standard of per-credit metering. This removes friction and cost unpredictability, and aligns the vendor's incentive with data quality.
- **Data Provenance**: Every record carries a source and timestamp. Unlike most providers that blend data from unattributed sources (co-op models), RevenueBase builds from primary signals and provides full traceability.
- **Clean & Enrich First**: Before selling new data, the platform fixes existing CRM data through canonical ID matching, stale job updates, and email verification — a service most competitors avoid because there's no per-credit revenue in it.
- **Continuous Verification Loop**: 30M+ daily signals keep data fresh; contacts are re-verified every 90 days, emails every 60 days.

## Strategic Focus
- **AI-Native Infrastructure**: The company is positioning itself as the data layer for autonomous GTM systems and AI agents, which require unlimited, unmetered access to reason across entire datasets.
- **Developer-First Onboarding**: Self-service signup with 500 free API credits and masked data feeds (full schema, PII redacted) — no sales call required to start prototyping. [revenuebase.ai](https://revenuebase.ai/)
- **Embedded Data**: Serving GTM SaaS companies (like Clay and Orbital) that embed RevenueBase data into their own products, expanding reach beyond direct GTM teams.

## Why Work Here
- **Culture & Mission**: The team is building what they describe as "infrastructure for autonomous go-to-market," with a focus on solving a structural problem in B2B data (broken incentives from per-credit pricing). The founder, Mark Feldman, previously led product and marketing at NetProspex (acquired by Dun & Bradstreet for $125M), bringing deep domain experience. [revenuebase.ai](https://revenuebase.ai/company)
- **Remote-First with HQ**: The company is headquartered in Waltham, MA, but operates as a remote-first organization. Roles are listed as "Remote" or "In-Office or Remote," with the typical time on-site listed as "None." [builtin.com](https://builtin.com/company/revenuebase)
- **Engineering Focus**: The team is small (11 employees) and growing, with active roles for a Data Engineer, Full Stack Developer (Backend), and Customer Engineer. This suggests a hands-on, high-impact environment where engineers shape the core data infrastructure.
- **Notable Perks**: Startup pricing program for customers; internally, the small team size implies significant ownership and direct impact on product and architecture.
