Gong vs. Fireflies (vs. ZoomInfo): Full 2026 Comparison

Choosing between Gong and Fireflies for conversation intelligence comes down to five questions:

• Do you need meeting transcription and notes, or a revenue operations platform that uses conversations as one input among many?

• Do you need AI that records what happened on a call, or AI that tells you why a deal moved and what to do next?

• Is your goal helping individuals stay organized after meetings, or giving revenue leaders visibility across every deal and rep?

• Does your team need affordable meeting documentation, or will you invest for pipeline intelligence and forecasting?

• Should conversation data live in its own silo, or do you need it connected to contact data, intent signals, and your CRM in one place?

In short, here's what we recommend:

Gong serves revenue teams that want conversation intelligence tied to deal execution, forecasting, and coaching. Its platform captures calls, emails, and meetings, then uses a proprietary dataset of more than three billion customer interactions to surface deal risks, score pipeline health, and automate CRM updates through 15+ AI agents. Gong was named a Leader in the inaugural 2025 Gartner Magic Quadrant for Revenue Action Orchestration. But Gong publishes no prices, charges a platform fee on top of per-user licenses, and its breadth creates an onboarding investment that smaller teams may not need.

Fireflies.ai is the AI meeting assistant for teams that need accurate transcription, searchable meeting archives, and automated summaries on a budget. With 95% transcription accuracy, support for 100+ languages, and a free plan with 800 minutes of storage, Fireflies serves 20 million users across 500,000+ organizations. Its Live Assist feature provides real-time coaching during meetings. But Fireflies focuses on meeting documentation and team collaboration, not pipeline management, deal intelligence, or revenue forecasting.

Both platforms capture conversations. But conversations are only one piece of the revenue puzzle. Understanding why deals close requires connecting what a prospect said on a call with who they are, what they're researching, and how their company is changing. That full picture separates intelligence from transcription.

ZoomInfo is a GTM platform that lets your sales reps walk into every call knowing why a deal is moving, who's championing it, and what's likely to happen next. Marketers can describe audiences in plain language and launch plays against accounts that match proven win patterns. Leaders can see deal risk before it shows up in CRM stage fields. That depth comes from the GTM Context Graph, an intelligence layer built on 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses, processing 1.5B+ data points daily by unifying this data with your CRM records, conversation transcripts, and behavioral signals. Conversation intelligence comes through Chorus, which captures and analyzes calls, emails, and meetings, then feeds those insights into the GTM Context Graph. Your team accesses it all through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end.

If connecting conversation intelligence with verified contact data, intent signals, and deal execution sounds like what your team needs, see how ZoomInfo works.

Gong vs. Fireflies vs. ZoomInfo at a glance

Meeting documentation vs. deal intelligence vs. full GTM context

These three platforms operate at different levels of the revenue stack.

Fireflies captures what happened in a meeting. It records, transcribes, summarizes, and makes conversations searchable. Its AskFred assistant lets you query your meeting archive in natural language, and 200+ AI Skills can extract specific outputs like sales scorecards or candidate evaluations. For teams whose primary need is "never miss what was said," Fireflies delivers.

Gong starts with conversation capture but extends into deal execution. It doesn't just tell you what a prospect said on a call. It connects that conversation to the deal's CRM data, tracks whether the right stakeholders are engaged, identifies risk signals, and generates a pipeline forecast. The Revenue Graph maps every interaction to accounts and opportunities automatically. Gong's AI analyzes patterns across three billion+ customer interactions to predict which deals will close and which are stalling.

ZoomInfo operates one layer deeper. Conversations matter, but they're one signal among many. The GTM Context Graph combines conversation intelligence (via Chorus) with verified contact data, intent signals, technographic intelligence, and CRM records to build the full context behind a deal. As ZoomInfo CPO Dominik Facher explains: "The CRM recorded the state change. It has no record of why it happened." A CFO joining a call and asking about six-month ROI is what accelerated the deal. A VP going quiet for eight days is what almost killed it. The GTM Context Graph captures these signals and connects them to outcomes.

The difference matters when you ask each platform "Should I be worried about this deal?" Fireflies can tell you what was discussed. Gong can analyze the conversation patterns and flag risk. ZoomInfo can add that the prospect company just had a hiring freeze, three competitors are researching the same category, and the economic buyer changed roles last month.

Conversation intelligence depth: what each platform actually analyzes

Gong and Fireflies both record and transcribe calls, but they extract different things from those recordings.

Fireflies tracks talk time, words per minute, filler word frequency, monologue duration, talk-to-listen ratios, silence duration, and question counts. Its Topic Trackers let you monitor custom keywords and phrases across meetings, and sentiment analysis uses a proprietary NLP algorithm to gauge positive, negative, and neutral tones. This is useful for coaching reps and understanding meeting dynamics.

Gong goes further by connecting conversation signals to deal outcomes. Its AI uses detection that goes beyond keyword matching to identify complex concepts: budget constraints mentioned indirectly, competitive positioning shifting mid-conversation, or executive sponsorship signals that correlate with closed-won deals. Smart Trackers understand context rather than matching words.

ZoomInfo's Chorus provides conversation intelligence within a broader context. It records and analyzes calls with AI-generated insights on talk ratios, sentiment, and objection detection. But Chorus also feeds into the GTM Context Graph, connecting what was said on a call to ZoomInfo's third-party signals: intent data, org chart changes, technographic shifts, and company news. A competitive mention on a call gets connected to intent data showing the prospect is actively researching that competitor, giving sellers a fuller picture than either conversation signal alone.

AI agents and automation take different approaches

All three platforms use AI beyond basic transcription, but their approaches differ.

Fireflies offers 200+ AI Skills that run against meeting transcripts to produce specific outputs: BANT qualification data, candidate scorecards, customer satisfaction analysis, and follow-up email drafts. These skills execute through a Rules Engine that can trigger automatically based on meeting type. The approach is meeting-centric: AI processes what happened in a conversation and produces an artifact.

Gong deploys 15+ AI agents that operate across the revenue cycle, not just on individual calls. AI Deal Reviewer evaluates deals against sales methodologies. AI Deal Predictor assigns probability scores based on 300+ buying signals from 2.5 billion conversations. AI Composer drafts personalized emails from full deal context. AI Trainer creates practice scenarios from real conversations. These agents are included with Gong licenses at no additional cost, configured through a no-code Agent Studio.

ZoomInfo takes a platform approach where AI operates on the full GTM Context Graph, not just conversations. GTM Workspace gives sellers AI-generated account briefs pulling CRM history, company news, ZoomInfo signals, and stakeholder context. An Action Feed surfaces in-market buyers with pre-drafted actions on every signal. GTM Studio lets marketers and RevOps teams describe audiences in natural language and launch multi-channel plays. The intelligence behind these actions draws from conversation data, B2B contact data, intent signals, and CRM records simultaneously.

Real-time meeting assistance: Fireflies leads, Gong is catching up

For in-the-moment help during live calls, Fireflies has the edge.

Fireflies' Live Assist, launched November 2025, surfaces answers from past meetings, documents, and knowledge bases during active conversations. Sales reps can pull up pricing discussions from previous calls without breaking the flow. The feature includes pre-meeting briefings, in-meeting coaching, and post-meeting summaries. Through a partnership with Perplexity, users can run real-time web searches during meetings via voice ("Hey Fireflies!") or text commands.

Gong's real-time capability is still developing. Gong Assistant, introduced as part of Mission Andromeda in February 2026, provides conversational AI for natural-language queries about accounts and deals, but it "will be generally available in the coming months." Gong's current strength is retrospective analysis, not live guidance.

Source: Gong

ZoomInfo does not position itself as a real-time meeting assistant. Its value is in the intelligence available before and after meetings. A seller opening GTM Workspace before a call sees a complete account brief with buying signals, org chart context, and AI-recommended talking points, all drawn from the GTM Context Graph. The preparation helps sellers walk into calls knowing what matters.

The data gap changes the equation

This is where comparing conversation intelligence tools in isolation misses the point.

Neither Gong nor Fireflies includes a native B2B contact and company database. Both record what happens during conversations with people you've already connected with. But before a conversation happens, someone has to find the right person, verify their contact information, and understand whether their company is in-market.

ZoomInfo provides this entire upstream layer. 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses mean sellers start with accurate, verified data. Buyer Intent signals track when companies are researching relevant topics, drawn from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. WebSights identifies which companies visit your website.

This data doesn't just help sellers prospect. It feeds the GTM Context Graph, enriching every conversation with external context. When Chorus captures a call where a prospect mentions evaluating competitors, ZoomInfo can connect that to intent data showing the prospect's company is researching three competing solutions, company data revealing a recent funding round, and org chart intelligence identifying additional stakeholders to engage. Neither Gong nor Fireflies can replicate that connected intelligence without third-party data integrations.

In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, an independent consultant concluded that "no other competitor came even close" to ZoomInfo's data quality.

Revenue forecasting and pipeline management

This capability separates full revenue platforms from meeting tools.

Fireflies does not offer revenue forecasting or pipeline management. It's a meeting intelligence tool, not a deal management system. Teams using Fireflies rely on their CRM or a separate platform for pipeline visibility.

Gong Forecast is built on reality-based forecasting: it uses signals from actual conversations rather than rep-reported CRM data to validate pipeline. The AI Revenue Predictor processes 300+ signals and predicts outcomes with 20% more precision than CRM-only algorithms. Gong Labs research found that only 1% of customer interactions make it into the CRM, which explains why conversation-based forecasting outperforms traditional approaches.

ZoomInfo approaches deal intelligence through the GTM Context Graph rather than a standalone forecasting module. By combining conversation data with intent signals, contact engagement patterns, and company-level changes, ZoomInfo surfaces deal risk and opportunity from a broader signal set. GTM Workspace gives sellers prioritized accounts and AI-generated next actions based on this full context. Thomson Reuters increased closed-won deals by 40% and achieved 115% average quota attainment each month using Workspace.

Pricing reflects different markets

The pricing structures reveal who each platform is built for.

Fireflies is the most transparent and affordable. The free plan provides 800 minutes of storage, unlimited transcription (with rate limits), and limited AI summaries. Pro costs $10/seat/month annually with unlimited transcription and 8,000 minutes of storage. Business costs $19/seat/month annually and adds video recording, conversation intelligence, and team analytics. Enterprise is $39/seat/month with HIPAA compliance and private storage.

The catch: AI credits. Fireflies' advanced features consume credits purchased separately, ranging from $5/month for 50 credits to $600/month for 10,000 credits. Unused credits expire at the end of each billing cycle. Multiple users on G2 report confusion about credit allocation and unexpected costs beyond the base subscription.

Gong publishes no prices. The model is per-user licenses plus a platform fee based on team size, with modular add-ons for Forecast, Engage, Enable, and Data Cloud. Prospects choose a team-size band (1-50, 51-1,000, 1,001-9,999, or 10,000+) before receiving a custom proposal. All fees are non-cancelable and non-refundable. The platform fee means smaller teams pay a disproportionate share of the base cost. On the other hand, all AI agents are included with licenses at no extra charge.

ZoomInfo also uses custom-quoted pricing based on seats, credit volume, and features. However, ZoomInfo offers two free entry points: ZoomInfo Lite (permanent free tier with 10 monthly export credits and access to the B2B database) and a 7-day free trial with broader feature access. ZoomInfo is shifting toward consumption-based pricing tied to data access and AI activity.

For a team of 20 reps, Fireflies Business would run roughly $380/month (before AI credit costs). Gong and ZoomInfo require custom quotes, with both at enterprise price points.

Integration and ecosystem breadth

Fireflies integrates with 90+ tools spanning video conferencing (Zoom, Google Meet, Teams, Webex), CRMs (Salesforce, HubSpot), collaboration tools (Slack, Notion, Asana), and storage platforms. Its GraphQL API and Zapier integration extend connectivity to 5,000+ apps. The focus is on pushing meeting data into existing workflows.

ZoomInfo maintains 120+ partner integrations through its App Marketplace, with Cloud Partners enabling direct data ingestion into AWS, Google Cloud, Snowflake, and Databricks. The Enterprise API provides programmatic access to ZoomInfo's full data and intelligence layer, and the MCP server connects AI models to ZoomInfo data with no custom coding. API access is included in all relevant plans, making ZoomInfo practical for teams building custom tools or AI agents.

Security and compliance comparison

All three platforms meet enterprise security requirements, with differences in depth.

Fireflies holds SOC 2 Type II, GDPR, and HIPAA-BAA compliance (Enterprise tier). The company commits to never using customer meeting data to train AI models and maintains a zero-day data retention policy with all vendors. Enterprise customers can use private storage for data residency control.

Gong carries the broadest certification portfolio: SOC 2 Type II, ISO 27001, ISO 27017, ISO 27018, ISO 27701, ISO 42001 (AI Management), PCI DSS, CSA STAR, and EU-U.S. Data Privacy Framework. The ISO 42001 certification for AI management is notable; Gong is one of the first revenue AI platforms to hold it. Customer data is never used to train generative models, and customers can configure bring-your-own-key encryption.

ZoomInfo maintains ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA certifications, all renewed annually. ZoomInfo is also a registered data broker in California and Vermont, relevant for teams under strict data privacy regulations.

Gong vs. Fireflies vs. ZoomInfo: Which should you choose?

The right platform depends on what problem you're solving.

Choose Fireflies if:

• Meeting documentation and team collaboration are your primary needs

• You want an affordable tool with a generous free plan

• Your team needs accurate transcription across many languages

• You want flexibility to access data through native apps, APIs, or MCP in any tool

See how ZoomInfo connects conversation intelligence with the full GTM picture.

Gong and Fireflies both capture conversations well. But conversations happen in a broader context. Fireflies documents that context for individuals. Gong analyzes it for revenue teams. ZoomInfo connects it to external data, signals, and intelligence that reveal why deals move, who to talk to next, and where to focus your team's energy. For revenue organizations that want every conversation informed by the full picture, that connected intelligence is the difference.

Gong vs. Fireflies vs. ZoomInfo FAQ

What is the fundamental difference between Gong, Fireflies, and ZoomInfo?

Fireflies is an AI meeting assistant focused on transcription, summaries, and searchable meeting archives. Gong is a revenue AI platform that uses conversation intelligence for deal execution, pipeline forecasting, coaching, and engagement. ZoomInfo is a GTM platform that combines conversation intelligence (via Chorus) with a B2B data platform and a GTM Context Graph that processes 1.5B+ data points daily, fusing conversations, CRM data, intent signals, and behavioral data into unified deal intelligence.

Which platform is most affordable for a small team?

Fireflies is far more affordable, with a free plan offering 800 minutes of storage and paid plans starting at $10/seat/month. Gong and ZoomInfo both require custom quotes with enterprise-level pricing. ZoomInfo does offer a permanent free tier called ZoomInfo Lite with access to its B2B database and 10 monthly export credits.

Can Fireflies replace Gong for sales teams?

Fireflies covers meeting transcription, basic conversation analytics, and AI-generated summaries well. But it lacks Gong's deal intelligence, revenue forecasting, sales engagement, pipeline management, and coaching capabilities. Sales teams that need to predict deal outcomes, track methodology adoption, or automate CRM updates from conversations will find Fireflies insufficient as a Gong replacement.

Does ZoomInfo have conversation intelligence built in?

Yes. ZoomInfo acquired Chorus, which captures and analyzes calls, meetings, and emails with AI-powered insights on talk ratios, sentiment, and objection detection. Chorus feeds into ZoomInfo's GTM Context Graph, connecting what was said on a call with ZoomInfo's data on contacts, companies, intent signals, and technographics to provide broader deal context than conversation data alone.

Which platform provides the best real-time meeting assistance?

Fireflies currently leads with Live Assist (launched November 2025), which surfaces answers from past meetings and knowledge bases during active conversations and includes a Perplexity-powered real-time web search feature. Gong's equivalent, Gong Assistant, was announced in February 2026 but is not yet generally available. ZoomInfo focuses on pre-meeting intelligence through GTM Workspace rather than live in-call assistance.

How do the platforms handle data privacy and AI model training?

All three commit to not using customer data for AI model training. Fireflies maintains a zero-day data retention policy with AI vendors and offers private storage for Enterprise customers. Gong holds the broadest certification portfolio, including ISO 42001 for AI Management, and offers bring-your-own-key encryption. ZoomInfo holds ISO 27001, ISO 27701, SOC 2 Type II, and TRUSTe GDPR/CCPA certifications, all renewed annually.

Which platform is best for organizations that need both prospecting data and conversation intelligence?

ZoomInfo is the only platform among the three that includes both a B2B contact and company database and conversation intelligence. Gong and Fireflies capture conversations but do not include native prospecting data. Teams using those platforms need a separate data provider for contact information, company intelligence, and intent signals.

Can I use more than one of these platforms together?

Yes. Fireflies and Gong both integrate with CRMs and other tools. ZoomInfo's data can be consumed via API and MCP in any front-end, including tools that integrate with Gong or Fireflies. Some organizations use Fireflies for meeting documentation across all departments while relying on ZoomInfo for sales-specific intelligence and prospecting data.
