MarketBetter vs Sumble: Complete Comparison for B2B Sales Teams (2026)
Sumble and MarketBetter both help B2B sales teams find and close deals — but they approach the problem from fundamentally different angles.
Sumble, founded by Kaggle co-founders Anthony Goldbloom and Ben Hamner, builds a knowledge graph of 2.6 million companies to surface technographic data: which tools companies use, who's making decisions, and what projects are being launched. It's backed by $38.5M in funding from Coatue and Canaan Partners, with angel investors including Marc Benioff and Nat Friedman.
MarketBetter identifies who's visiting your website right now — then gives your SDRs a prioritized daily playbook with built-in email, dialer, and AI chatbot to act on those signals immediately.
The core difference: Sumble tells you about accounts. MarketBetter tells your reps what to do next — and gives them the tools to do it.
Where Sumble Excels
Let's be fair about what Sumble does well:
Deep Technographic Intelligence
Sumble's knowledge graph trawls the web, social media, job boards, company websites, and regulatory filings to build detailed profiles of what tools companies use across departments. If you need to know whether a target account uses Snowflake in their data engineering team or just deployed Vercel for their frontend — Sumble surfaces that.
This is genuinely useful intelligence. Knowing a company's tech stack tells you whether your product fits, what you're replacing, and who to target within the org.
Enterprise-Grade Data Products
Sumble offers an API, Sumble Enrich (bulk data enrichment), and Sumble Signals (real-time alerts when companies adopt new tools or launch projects). For enterprises building custom GTM workflows, these are powerful building blocks.
Viral Growth Inside Organizations
Sumble grows fast inside companies — reportedly going from 1 to 500 monthly active users in 6 months at some accounts. Their free web app lets anyone search, and insights spread through Slack channels. Brendan Short of The Signal newsletter called it "the most interesting sales tool I found last year."
Where MarketBetter Excels
First-Party Website Visitor Identification
This is the fundamental difference. Sumble aggregates public data from across the web. MarketBetter identifies who's visiting your website — giving you first-party intent signals that are dramatically more actionable than scraped technographic data.
When someone from a target account visits your pricing page, that's a buying signal Sumble can't provide. MarketBetter catches it in real time.
The Execution Layer
Sumble is intelligence. MarketBetter is intelligence plus action.
With Sumble, once you know a company is using a competitor's tool, you still need to:
- Export that data to your CRM
- Build a sequence in Outreach or SalesLoft
- Find the right contact in another tool
- Make calls through a separate dialer
- Hope your SDR prioritizes the right accounts
With MarketBetter, all of this happens in one platform:
- Smart Dialer — built-in, no Orum or Nooks subscription needed
- Email automation — hyper-personalized sequences powered by AI
- AI Chatbot — engages website visitors automatically, 24/7
- Daily SDR Playbook — every morning, your reps get a prioritized list: call this person first, email this account second, follow up with this lead third
Daily SDR Playbook
This is where the gap is widest. Sumble gives data. MarketBetter gives your reps a daily action plan.
The SDR Playbook combines website visitor data, intent signals, and engagement history into one prioritized task list. No more "20 tabs and a spreadsheet" workflow. Your rep opens MarketBetter, sees their playbook, and starts executing.

Who Should Choose Sumble?
Sumble is a strong fit if you:
- Need deep technographic intelligence — knowing exactly what tools a company uses across departments is Sumble's core strength
- Already have an outreach stack — if you're invested in Outreach, SalesLoft, and a standalone dialer, Sumble layers on top as a data source
- Want an API-first approach — Sumble's API and Enrich products are built for teams with custom GTM workflows
- Sell to developers or technical buyers — Sumble's data is especially strong for tech companies (Snowflake, Figma, Wiz, and Vercel are among their 19 enterprise customers)
Who Should Choose MarketBetter?
MarketBetter is the better fit if you:
- Want to know who's on your website right now — first-party visitor identification is a fundamentally different (and more actionable) signal than scraped public data
- Need an all-in-one platform — if your SDRs are juggling visitor ID, dialer, email, and CRM in separate tabs, MarketBetter consolidates everything
- Want prioritized daily actions — the SDR Playbook turns signals into a ranked task list, not just a data feed
- Care about real-time engagement — the AI chatbot captures intent while visitors are still on your site
- Want to reduce tool sprawl — instead of Sumble + Outreach + Orum + a chatbot tool, MarketBetter replaces all of them
The Intelligence vs. Execution Gap
This is ultimately the decision you're making:
Sumble is best-in-class at answering "what do we know about this account?" It builds a detailed map of a company's tech stack, projects, and contacts. But it's a data platform — your reps still need separate tools to act on those insights.
MarketBetter answers a different question: "what should my rep do right now?" It combines first-party website intent with built-in email, dialer, and an AI chatbot to create a complete execution loop.
For most B2B sales teams — especially those with 5-50 SDRs who are drowning in tools — the execution layer is what moves the needle.
