Topo Review 2026: Full Platform Breakdown

Topo is an AI-powered outbound sales platform that replaces the traditional SDR workflow with an autonomous agent. Rather than asking reps to manage separate tools for prospecting, sequencing, and deliverability, Topo bundles everything into one platform and pairs it with a human strategist. For small B2B teams that want to launch outbound without hiring, it works.

To create this Topo review, we analyzed the platform in detail. It's a good fit if:

• You're an SMB or early-stage startup launching outbound for the first time

• You want a single platform covering lead sourcing, sequencing, and email infrastructure

• You prefer a managed service with a human strategist guiding your campaigns

• Your team runs on HubSpot and doesn't need other CRM integrations

• You value intent-signal-based prospecting over high-volume outreach

However, Topo might not be the best choice if:

• You need a B2B data platform with hundreds of millions of verified contacts

• Your GTM strategy extends beyond outbound to include ABM, advertising, and conversation intelligence

• You require CRM integrations with Salesforce, Microsoft Dynamics, or other platforms beyond HubSpot

• You need third-party security certifications and compliance infrastructure

• You want a platform that scales from prospecting through deal execution and customer expansion

In this case, you should consider ZoomInfo: an AI go-to-market platform built on the largest verified B2B database in the industry. With 500M contacts, 100M companies, and a GTM Context Graph that combines your CRM data with third-party intelligence to show not just what's happening in your deals but why, ZoomInfo covers the full go-to-market process through front-ends for sellers and marketers, or through APIs and MCP in any tool your team already uses.

We've included a detailed look at ZoomInfo later in this review for teams whose needs extend beyond outbound prospecting. If you want a platform that covers the full go-to-market process, you can start with ZoomInfo's free plan here.

What is Topo?

Topo is a cloud-based AI sales platform founded in August 2022 in Paris, France. Dan Elkaim, Robin Philibert (COO), and Leonard Henriquez (CTO) created it after meeting at Aircall, where Dan and Robin spent three years building the mid-market sales team and watched enterprise conversion rates drop from 65-70% to 15% as deal complexity grew.

That experience shaped Topo's thesis: outbound prospecting requires too many disconnected tools and too much manual work for small teams to execute well. Topo's answer is an AI agent that runs prospecting autonomously: detecting buying signals, finding leads, qualifying them against custom criteria, personalizing outreach, and scheduling meetings.

The company raised EUR1 million in pre-seed funding from Kima Ventures, BPI France, and Snaw Ventures, and was accepted into Y Combinator's Winter 2024 batch. With approximately 12 employees and a 4.9-star G2 rating across 118 reviews, Topo targets B2B SMBs: founders who don't want to hire a dedicated SDR, full-cycle salespeople building pipeline, and small teams testing new markets.

Topo Pros & Cons

Topo Review: How it Works & Key Features

AI Outbound Agent: Topo's prospecting engine handles lead discovery, qualification, and outreach with human oversight at every step.

Topo's AI Outbound Agent is the platform's core feature: an autonomous system that handles outbound prospecting for sales reps. Topo describes it as a system that "lives while you're sleeping", finding leads, qualifying them, enriching contact data, personalizing outreach, and booking meetings without human intervention.

The agent runs a sequential workflow: it monitors for intent signals, finds new matching leads on a daily or weekly cadence, enriches contact data (discarding leads that cannot be enriched), then evaluates each lead against custom qualification criteria before generating personalized outreach.

Source: Topo

The qualification step stands out because of AI Criteria, natural-language conditions the agent verifies by scraping public sources (websites, company pages, news articles). Users can write rules like "is recruiting an SDR" or "is an OEM" that no standard data provider enriches natively. The agent shows its reasoning for every decision, including the exact web sources used, so users can audit the logic.

Users retain control through human guardrails: they can reject a lead, edit the personalized message, or add a manual approval step before enrollment in a sequence. The agent's behavior is shaped by an Organisation Context settings page where users define their company overview, ICP, competitive positioning, and exclusion lists.

Intent Signals: Topo monitors 15+ sources to surface accounts showing real-time buying behavior.

Topo's Intent Signals system tracks the digital footprints of target accounts across the web, LinkedIn, job boards, and CRM data. An intent signal is a behavioral clue that someone is looking into a problem you solve. This shifts prospecting from static profile matching to observed behavior.

Source: Topo

The platform offers five pre-built signal categories:

• Competition: detects when leads interact with competitor content, follow competitors, or mention competitors in job postings

• Social: tracks event participation, relevant posts, and influencer interactions

• Hiring: identifies companies posting jobs with specific keywords or leads recently hired into new positions

• Technology: flags companies using integrable tools or competitive tools they could switch from

• CRM: reactivates closed-lost deals when conditions change and surfaces marketing-engaged companies

Beyond these categories, users can define custom signals in natural language: "Company raised a funding round in the last 30 days," "Company mentions SOC-2 certification on website," or any other pattern discoverable by browsing the web.

The signal system feeds into the AI agent's workflow. When a signal fires, the agent starts scraping, enriching, qualifying, and launching outreach without manual handoff.

Multichannel Sequences: Topo coordinates email and LinkedIn outreach through automated cadences with AI-generated personalization.

Topo's Multichannel Sequences automate coordinated messaging across LinkedIn and email. The architecture separates lists from sequences (who to contact vs. how to contact), so multiple audience segments can feed a single outreach cadence without duplicating setup.

Source: Topo

Each sequence runs in one of two modes: Co-pilot mode (every lead requires human

approval before outreach begins) or Auto-pilot mode (leads are approved and enrolled automatically). A daily contact cap controls volume, and the platform detects lead timezones when available to ensure messages land during business hours.

Source: Topo

Messages use AI Variables, dynamic content blocks generated in real time from lead and company data. Unlike static merge tags, AI Variables generate personalized text at send time. Users define each variable with a prompt, guidelines, and output examples to control tone and format.

The sequences also support multi-identity rotation, distributing outreach across different sales reps' names, email addresses, and LinkedIn accounts within the same cadence.

Lead Data Sources: Topo aggregates 20+ data providers into a single enriched database with five search modes.

Topo's Lead Data Sources aggregates 20+ external sources into one database of companies and contacts.

Users access this data through five search modes: a structured Lead Database with firmographic filters, LinkedIn Search for professional background queries, Signal Monitoring for real-time business events, Web Search using natural-language queries, and CSV import for existing contacts.

Source: Topo

Enrichment follows a waterfall model: Topo checks multiple sources and stops as soon as a valid email is found. Credits are only consumed for successfully verified contacts; leads without a valid email are discarded and cost nothing. Users can explore and refine searches without incurring costs, since enrichment only fires when a list is saved.

Source: Topo

Filters cover company attributes (size, type, funding stage, industry, HQ location, per-department headcount) and people-level details (job title, seniority, job function, location, years of experience). Growth signal filters track headcount growth, follower growth, job openings growth, and web traffic growth over 6- and 12-month windows.

Email Infrastructure: Topo manages sending domains, DNS authentication, warm-up, and ongoing deliverability monitoring.

Topo's Email Infrastructure is a managed sending system built into the platform.

Source: Topo

It handles secondary domain purchasing, DNS configuration (SPF, DKIM, DMARC), mailbox clustering, warm-up through a private network, and ongoing monitoring, all without IT involvement.

Source: Topo

New mailboxes go through a phased warm-up: low volume in days 1-7, gradual increases in days 8-14, and full capacity by weeks 3-4. During this period, users can launch LinkedIn-only sequences to keep outreach going while mailboxes build reputation.

The platform tests every mailbox every two weeks.

Source: Topo

If deliverability scores decline, Topo throttles volume before damage compounds. The scoring maps to sending capacity: score 10 = 30 emails/day, score 9 = 20/day, score 8 = 10/day, and a score of 7 or lower pauses sending entirely. When scores recover, volume ramps back up automatically.

Where Topo Falls Short

Topo handles outbound prospecting well for its target market, but several limitations surface as teams grow or their GTM needs expand. These gaps show a platform built for SMB outbound, not full go-to-market execution.

HubSpot-Only CRM Integration: All of Topo's case studies and product documentation reference HubSpot as the sole CRM integration. Salesforce, Pipedrive, Microsoft Dynamics, and other CRMs are absent from all public documentation. For B2B companies running on Salesforce (particularly mid-market and enterprise teams), this rules Topo out. G2 reviewers have noted a desire for broader Salesforce flexibility.

No Public Pricing and No Free Trial: Pricing sits behind a "Book a Demo" flow with no published tiers or price points. The Terms of Service state directly: "We do not offer free trials". Teams cannot estimate costs or test the platform before committing to a sales conversation and a signed contract.

Analytics and Reporting Gaps: G2 review summaries flag limited analytics and users wanting more visibility into revenue impact. Teams coming from mature sales engagement platforms may find reporting shallow. The current dashboards focus on campaign metrics (leads contacted, messages sent, replies) rather than pipeline-to-revenue attribution.

Outbound-Only Focus: Topo addresses one slice of the go-to-market process: outbound prospecting. It does not offer conversation intelligence, account-based marketing, website visitor identification, digital advertising, web form optimization, or data operations for CRM hygiene. Teams whose GTM strategy extends beyond cold outreach need additional tools for the rest of their workflow.

Early-Stage Company Risk: Founded in 2022 with approximately 12 employees, Topo is a YC-stage startup. No SOC 2, ISO 27001, or other third-party security certifications are publicly documented. Enterprise buyers requiring vendor-risk assessments, multi-year SLAs, or compliance infrastructure may find the company's maturity level insufficient.

Signal Coverage in Niche Markets: G2-sourced summaries note that "some signals have limited volume." This likely affects teams with specialized ICPs or those operating in categories without dense LinkedIn or job-posting signal coverage.

These limitations follow naturally from building a focused outbound tool for small teams. But they create a gap for organizations that need a platform covering the full go-to-market process, from data and intelligence to execution across every channel and team.

Top Topo Alternative for Scaling GTM Teams: ZoomInfo

ZoomInfo addresses Topo's limitations with an AI go-to-market platform built on the largest verified B2B database in the industry. Where Topo handles outbound prospecting for SMBs, ZoomInfo combines data, intelligence, and execution across the full go-to-market process. It serves sales, marketing, RevOps, and customer success teams through native front-ends or programmatic access in any tool.

B2B Data: ZoomInfo's verified database covers 500M contacts and 100M companies across three data dimensions.

What separates ZoomInfo from point solutions is data breadth and verification.

The platform covers 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses. A verification pipeline backed by 300+ human researchers achieves up to 95% accuracy on first-party data.

Beyond contact records, ZoomInfo provides company attributes, org charts, and technographics covering 30,000+ technologies across 200+ categories at 30+ million companies.

Buyer Intent data draws from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings monthly.

Guided Intent (exclusive to ZoomInfo) identifies topics historically correlated with deal success rather than requiring manual topic selection.

This is externally validated: a Fortune 500 competitive RFP analyzing 25 million contacts across vendors concluded that "no other competitor came even close." ZoomInfo holds 133 No. 1 rankings on G2 across Sales Intelligence, Buyer Intent, and Data Quality categories, and was named a Leader in Forrester's Wave for Intent Data Providers and a Leader in Gartner's Magic Quadrant for ABM Platforms for two consecutive years.

SpringDB saw 2x-3x increases in campaign conversions, a 300% increase in database usability, and 30-50% uplift in average deal size after using ZoomInfo's enriched data for precise client targeting. (SpringDB)

GTM Context Graph: ZoomInfo's intelligence layer combines B2B data with your CRM, conversations, and behavioral signals to show why deals move or stall.

ZoomInfo's data gains context through the GTM Context Graph, an intelligence layer that processes 1.5B+ data points daily.

It combines ZoomInfo's third-party data with a customer's CRM records, conversation transcripts, email interactions, and behavioral signals into a single graph that captures not just what happened in a deal, but why.

A CRM records that a deal moved to Stage 4. Conversation intelligence captures what the VP of Finance said on the last call. Intent data logs a spike in research activity. The GTM Context Graph reasons across all three, connecting executive sponsorship, ROI-focused questions, and third-party signals showing the company is hiring new VPs and researching competitors. That reasoning powers AI-generated outreach that addresses specific concerns, GTM plays targeting accounts whose signal combinations match actual win patterns, and forecasts weighted by buying evidence rather than stage labels.

This layer rests on two decades of data unification work (entity resolution, semantic normalization, identity matching), now extended to first-party data through acquisitions like Chorus for conversation intelligence.

Seismic attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, reported 54% productivity gains, and saved 11.5 hours per week per seller by combining internal CRM data, external signals, and AI-driven context. (Seismic)

Universal Access: ZoomInfo delivers its intelligence through native front-ends for sellers and marketers, or via APIs and MCP in any tool.

Where Topo limits users to its own interface and a HubSpot connection, ZoomInfo delivers intelligence three ways.

GTM Workspace gives sellers one screen where prioritized accounts, AI-drafted outreach, and deal execution come together. AI agents handle account research, outreach generation, CRM updates, and signal monitoring. An Action Feed surfaces in-market buyers with pre-drafted actions on every signal.

GTM Studio gives marketers, RevOps, and GTM engineers a workspace where they define audiences, orchestrate campaigns, and measure pipeline in natural language. Pre-built GTM plays launch in one click; expansion plays that used to take 3 weeks now launch in 30 minutes.

APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform. ZoomInfo MCP connects AI models to B2B data without custom coding and currently supports Claude and ChatGPT. API access is included in all relevant plans.

All three draw from the same GTM Context Graph: the same data, the same reasoning, the same intelligence. Where you work doesn't limit the intelligence you get.

ZoomInfo integrates natively with Salesforce, HubSpot, and Microsoft Dynamics, along with 120 partner integrations covering marketing automation, sales engagement, data warehouses, and more.

BDO Canada's Senior Marketing Intelligence Analyst noted: "The plug-and-play aspect of the API means I can integrate it very easily into any process and get information at a moment's notice," achieving an 87% reduction in time spent on data dashboard updates. (BDO Canada)

Enterprise-Grade Security and Compliance: ZoomInfo maintains the certifications and infrastructure that regulated industries require.

ZoomInfo holds ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA certifications, all renewed annually. The company is a registered data broker in California and Vermont and maintains a dedicated Trust Center. With $1.25 billion in annual revenue, 35,000+ customers, and enterprise clients including Adobe, Snowflake, and JPMorgan, ZoomInfo provides the stability and compliance infrastructure that vendor-risk assessments demand.

It targets SMBs and early-stage startups that want to launch or scale outbound without hiring SDRs.

Does Topo offer a free trial or free plan?

No. Topo does not offer a free trial or free plan. All subscriptions require a commitment specified in a signed Order Form, and pricing is only available after booking a demo. ZoomInfo, by contrast, offers ZoomInfo Lite (a permanent free plan with access to its B2B database and 10 monthly export credits) plus a separate 7-day free trial of paid features.

What CRM does Topo integrate with?

Topo integrates with HubSpot only. The integration supports two-way contact and company syncing, activity logging, and exclusion logic based on HubSpot segments. Salesforce, Pipedrive, Microsoft Dynamics, and other CRMs are not supported. ZoomInfo integrates natively with Salesforce, HubSpot, and Microsoft Dynamics, plus over 120 additional tools through its marketplace.

How does Topo's pricing work?

Topo does not publish pricing. The business model charges based on the number of leads the AI agent contacts each month, as specified in the customer's Order Form. Subscriptions renew automatically unless written notice is given at least 30 days before the term ends, and no refunds are issued for early termination. Enrichment credits are consumed per lead enriched, with allocations managed through the assigned Account Manager.

What is the AI Outbound Agent?

The AI Outbound Agent is Topo's core feature: an autonomous system that detects buying signals, searches for matching leads, enriches contact data, qualifies leads against custom natural-language criteria, generates personalized outreach, and pushes context to HubSpot. Users can set the agent to run in Co-pilot mode (manual approval required) or Auto-pilot mode (fully automated). The agent shows its qualification reasoning with cited web sources for every lead.
