Fathom vs Fireflies: AI Meeting Notetaker for Small B2B Sales Teams Head-to-Head
Two AI notetakers pitched at the same small B2B sales team. We compared published pricing, CRM sync depth, free-plan viability, and AI-feature limits against each vendor's own docs as of September 2026.
Fathom takes the overall on three counts: a free plan a small team can actually work in, deeper native CRM field-mapping on its Business tier, and a 90-day money-back guarantee Fireflies doesn't match. Fireflies wins integration breadth (13 supported CRMs including Pipedrive, Zoho, and Attio against Fathom's shorter native list) and undercuts on entry-paid seat price ($10 vs $15/user/month annual). If your small B2B sales team runs on HubSpot or Salesforce and you want CRM field sync plus coaching, Fathom Business at $25/user/month is the higher-scoring pick. If you're on Pipedrive, Zoho, or a longer-tail CRM, or you want the cheapest paid seat with unlimited transcription, Fireflies Pro at $10/user/month is the defensible call.
Fathom and Fireflies are the two AI meeting notetakers small B2B sales teams shortlist most often. Both join Zoom, Google Meet, and Microsoft Teams calls, both produce transcripts and AI summaries, and both push notes into a CRM on paid plans. The buying decision comes down to four things a small sales team actually cares about: how much the seat costs at the tier that turns on CRM sync, how deep that sync goes, what the free plan can actually do, and whether the AI features are metered.
Every round below is scored against each vendor's own pricing, documentation, and integration pages as of September 2026. This is a documentation-based comparison, not a hands-on lab benchmark: where a claim comes from a vendor page, that page is in the sources list. Where numbers don't appear on an official page, they aren't stated here.
| Test category | Winner | Result & method |
|---|---|---|
| Free plan viability for a small sales team | Fathom | Fathom's free plan includes unlimited recordings and transcription with no time limit on stored recordings, but caps advanced AI summaries at 5 calls per month; after that only the basic chronological template is available. Fireflies' free plan also offers unlimited transcription and limited AI summaries in 100+ languages, but storage is capped at 400 minutes shared across the whole team, transcript downloads are blocked, and there's no video recording. For a two-to-five person sales team running daily calls, Fireflies' 400 team-wide storage minutes runs out in weeks, whereas Fathom's 5-summary cap only bites on the AI-summary feature itself. The free plan is a real workspace on Fathom and closer to an extended trial on Fireflies.How we measured it: Compared each vendor's published free-plan limits (recording, transcription, AI summary, storage, integration, export) on their own pricing pages as of September 2026, scored on whether a two-to-five-person sales team could run daily discovery calls on the free tier without immediately hitting a wall. |
| Entry paid tier — price and what it unlocks | Fireflies | Fireflies Pro is $10/user/month billed annually ($18 monthly) and turns on unlimited transcription, unlimited AI summaries, video recording capped at 2 hours per meeting, transcript downloads, 8,000 minutes of storage per seat, and unlimited integrations including CRM push. Fathom's cheapest tier with unlimited AI summaries is Premium at $16/user/month annual ($20 monthly), and its cheapest team-oriented plan is Team at $15/user/month annual ($19 monthly) with a two-seat minimum. On sticker price for a single-rep or two-rep team that just wants unlimited AI plus CRM push, Fireflies Pro is $5–6 cheaper per seat per month.How we measured it: Compared each vendor's cheapest paid seat on annual billing and audited what the tier unlocks (unlimited AI, video, downloads, storage, integrations) against each vendor's pricing page. |
| Native CRM sync depth (HubSpot, Salesforce) | Fathom | Fathom offers native HubSpot and Salesforce integrations that log call summaries, action items, and highlights to matching Contacts, Accounts, and Opportunities. Its Summary Note Sync to Deal Fields, the feature that maps AI-generated summaries directly to specific HubSpot deal fields, is gated to Business ($25/user/month annual) and Enterprise plans. Fireflies offers CRM sync on Pro and above, with conversation intelligence and team analytics added on Business ($19/user/month annual). Fathom's HubSpot listing shows the app was named HubSpot's 2025 Most Used App of the Year and has 20k installs from HubSpot. On the specific job of pushing structured, field-mapped meeting insight into HubSpot deal properties, Fathom's documented workflow is deeper.How we measured it: Compared each vendor's official CRM integration documentation for HubSpot and Salesforce, focused on what actually writes to CRM records at the entry-paid tier vs the tier where field-level sync becomes available. |
| CRM breadth beyond HubSpot and Salesforce | Fireflies | Fireflies lists 13 supported CRMs on its documentation: Affinity CRM, Attio, Close, Copper, Freshsales, HubSpot, Microsoft Dynamics 365, Pipedrive, Salesflare, Salesforce, Zendesk Sell, StartDeliver, and Zoho. Fathom's integrations page shows native HubSpot and Salesforce plus Zapier and Make as workflow bridges to everything else. For a small sales team already on Pipedrive, Zoho, Attio, Copper, or a niche CRM, Fireflies has a first-party path where Fathom asks the team to route through Zapier.How we measured it: Counted the CRMs each vendor lists as officially supported on their integration or documentation pages. |
| AI feature metering — hidden costs | Fathom | Fireflies' AI features run on a monthly credit allowance (20 on Pro, 30 on Business, 50 on Enterprise) alongside unlimited AI summaries on paid tiers. Fathom's paid tiers instead sell unlimited AI summaries once you're above the free-plan 5-summary cap, with all 15+ AI summary templates available on Premium and up. For a small sales team that runs 20+ meetings a week, Fathom's predictable "unlimited above the paywall" model produces a more knowable monthly bill than Fireflies' credit-metered one.How we measured it: Audited each vendor's documented AI-credit and quota model on their pricing page. |
| Risk-free trial window | Fathom | Fathom advertises a 90-day money-back guarantee on Premium, Team, and Business plans. Fireflies' pricing page publishes plan tiers and features but doesn't publish an equivalent multi-month money-back guarantee. For a small sales team standing up a notetaker on a full quarter of pipeline, the 90-day window is a decisive tie-breaker: it covers a full sales cycle before the seat cost is locked in.How we measured it: Compared each vendor's published trial and money-back terms on their pricing pages. |
| Total monthly cost for a five-rep sales team | Fireflies | On Fireflies Business at $19/user/month annual, a five-rep team pays $95/month for the tier that adds conversation intelligence and team analytics. On Fathom Business at $25/user/month annual, the same five reps pay $125/month, with the extra $30 buying Summary Note Sync to Deal Fields and coaching metrics. Fireflies is $30/month cheaper at five seats; whether that gap is worth Fathom's deeper HubSpot field mapping is the actual buying question, but on straight seat math Fireflies wins this round.How we measured it: Computed a five-seat total on the plan tier that unlocks HubSpot or Salesforce sync with CRM field mapping (where available), using each vendor's published annual-billing per-seat price. |
Fathom and Fireflies sell to the same buyer with the same pitch: an AI bot that joins every sales call, transcribes it, summarizes it, extracts action items, and pushes the result into the CRM. The four-point overall margin is narrow enough that the round breakdown matters more than the score, and the per-round methods above name exactly what each result is measured against.
Reading the result
Fathom took four of seven rounds (free-plan viability, native HubSpot and Salesforce sync depth, AI-feature metering, and trial risk) on the strength of a free plan a small team can actually work in, unmetered AI on paid tiers, and the 90-day money-back guarantee. Fathom offers that guarantee on Premium, Team, and Business plans, described as the most generous window in the AI meeting notetaker category, since most competitors, Fireflies included, don’t offer one.
Fireflies took three rounds (entry-paid pricing, CRM breadth, and total monthly cost at five seats) on the strength of a $10 annual seat and a first-party CRM list that stretches well past HubSpot and Salesforce. Fireflies integrates with a wide range of CRM platforms including Affinity CRM, Attio, Close, Copper, Freshsales, HubSpot, Microsoft Dynamics 365, Pipedrive, Salesflare, Salesforce, Zendesk Sell, StartDeliver, and Zoho.
How the free plans actually differ
The free-plan round is the one most small teams underweight. Both vendors advertise “unlimited transcription,” but the ceilings sit in different places.
On Fathom, the free plan gives you unlimited recordings and transcription with unlimited recording storage and no time limit, but advanced AI summaries are capped at 5 calls per month. After that, only the basic chronological template is available. That means a small team can run every discovery call through Fathom for free and pay only when they want the branded, structured summaries on more than five of them.
On Fireflies, the ceiling is storage, not AI. The Free tier records and transcribes meetings with limited AI summaries, but stores only 400 minutes of recordings for the whole team and blocks transcript downloads. Fireflies’ own guidance treats the free plan as an extended trial, not a workspace, and its storage cap is designed to be outgrown in weeks.
The practical consequence: a two-rep team doing four calls a day on Fireflies free will hit the 400-minute team-wide cap inside the first two weeks. The same team on Fathom free will keep every recording and transcript indefinitely, and will only feel the ceiling on the sixth AI-summarized call each month.
Where CRM sync actually differs
For a small B2B sales team, the notetaker’s real job isn’t the summary, it’s the CRM row that appears without a rep typing it. Both vendors do this on paid plans, but the depth is different.
Fathom’s native CRM sync targets HubSpot and Salesforce. On HubSpot specifically, Fathom’s Summary Note Sync to Deal Fields (the workflow that maps AI-generated summary content into specific HubSpot deal fields) is available only on Business and Enterprise plans. That’s the $25/user/month annual tier. On the HubSpot marketplace, Fathom was named HubSpot’s 2025 Most Used App of the Year and shows 20k installs from HubSpot.
Fireflies covers HubSpot and Salesforce too, but its edge is breadth. CRM integrations, including Salesforce, Zoho, and HubSpot, require at least the Pro plan, which turns on unlimited integrations, and the Business plan adds conversation intelligence and team analytics. The list of first-party CRM connectors (Affinity CRM, Attio, Close, Copper, Freshsales, HubSpot, Microsoft Dynamics 365, Pipedrive, Salesflare, Salesforce, Zendesk Sell, StartDeliver, Zoho) is the widest in the category on any single-vendor page.
If your CRM is HubSpot or Salesforce and you care about deal-field mapping, Fathom Business is the deeper integration. If your CRM is anything else on that Fireflies list, Fathom’s answer is Zapier or Make, and the round tips to Fireflies.
The AI-credit model
The single most important nuance for a Fireflies buyer is that “unlimited AI summaries” and “unlimited AI features” aren’t the same thing. Fireflies markets unlimited summaries on paid tiers, and summaries are indeed uncapped there, but the pricing page also documents a monthly AI credit allowance (20 on Pro, 30 on Business, 50 on Enterprise) that governs the broader AI feature set.
Fathom doesn’t run this model on its paid plans. The free plan is a real product, not a teaser, and what “free” doesn’t include is unlimited AI. Once you cross into Premium, Team, or Business, the AI features aren’t credit-metered.
For a five-rep team doing 15–25 calls a week each, the credit ceiling on Fireflies is the variable most likely to shape the real monthly bill. That’s the reason the AI-metering round tilts to Fathom despite Fireflies’ lower entry price.
Mapping the rounds to a buying decision
If your team is on HubSpot or Salesforce and you want structured meeting insight pushed into deal properties without a rep touching the record, Fathom Business at $25/user/month annual is the higher-scoring pick. The 90-day money-back guarantee also means the first quarter of use is effectively risk-free.
If your team is on Pipedrive, Zoho, Attio, Copper, or a longer-tail CRM, Fireflies is the shorter path. Its first-party connector list covers all of those, and Fathom will ask you to bridge through Zapier.
If you’re a one- or two-rep team that wants the cheapest usable seat with CRM push and video recording, Fireflies Pro at $10/user/month annual is the lowest-friction start, provided the AI-credit ceiling doesn’t bite your workflow.
Meeting capture is only one layer of a small B2B sales stack. The upstream layers (deal-aware pre-call briefs, dialer coverage, and lead discovery) sit in their own categories, and the notetaker choice above is easiest to make once those are already scoped. Our current picks in those adjacent categories live in the meeting prep tools ranking, the parallel and power dialers ranking, and the lead discovery platforms ranking.
What could change this ranking
Two variables would flip the overall. If Fireflies removes the AI-credit meter on Pro and Business, the AI-metering round moves closer to a tie and the four-point overall margin narrows. If Fathom ships a first-party Pipedrive or Zoho connector to match Fireflies’ 13-CRM list, the CRM breadth round flips too and Fathom’s lead widens materially. Neither change is announced on either vendor’s own pages as of September 2026, so the current call stands until a vendor pricing or docs page moves.
