Gong vs New AI-Native Alternatives (Sybill, Oliv, Momentum): Is More AI Enough?

Sybill, Oliv and Momentum automate more than Gong in specific places: Sybill writes CRM updates and briefs, Oliv runs agents across deals and forecasts, and Momentum, now part of Salesforce, turns calls into CRM data and workflows. More AI is not enough on its own. What matters is when the AI acts, what context it uses and who sees it.

Disclosure: we build Proshort, which takes a different approach and is covered near the end. Gong, Sybill, Oliv and Momentum are described from their own websites and announcements as checked in October 2026.

Key takeaways

• Momentum is no longer an independent alternative: Salesforce completed its acquisition on March 2, 2026, and Momentum now powers Salesforce Conversation Intelligence.

• Sybill and Oliv compete with Gong on automation and price transparency: both publish pricing, and both lean on agents that update the CRM for reps.

• Most of this AI still works on transcripts after the call. The rep is on their own while the buyer is talking.

• Judge any tool on four questions: when the AI acts, what context it uses, who sees the output, and how its actions are governed.

Gong vs Sybill vs Oliv vs Momentum at a glance

What is Gong still best at?

Gong describes itself as an AI operating system for revenue teams. It records and transcribes calls, detects topics and sentiment, tracks deals and pipeline, updates the CRM and runs coaching scorecards and embedded AI agents (Gong).

Its advantages are maturity and breadth: a long track record, one platform from call analysis to pipeline, and a familiar name in enterprise RFPs. If you need one vendor that procurement already trusts, Gong is the safe default. The trade-offs are a price you cannot see before talking to sales (Gong describes a per-user license plus a platform fee) and value that arrives mostly after the call.

What do the AI-native alternatives do differently?

Sybill: CRM updates and briefs written for the rep

Sybill calls itself an AI sales assistant for revenue teams. It auto-updates every CRM field after each sales conversation, writes pre-meeting briefs and call summaries, and adds deal inspection, coaching modules, an AI sales agent and an MCP server (Sybill). It publishes pricing, including a free tier. Choose it when the main pain is rep admin.

Oliv: agents that run the deal and the forecast

Oliv describes itself as autonomous AI agents for the entire revenue lifecycle, with named agents such as Deal Driver, Forecaster and CRM Manager that fix stale records and close dates (Oliv). Its own blog describes a voice agent with real-time methodology prompts during active calls. Oliv publishes per-user pricing and notes that platform fees are excluded (Oliv pricing).

Momentum: now part of Salesforce

Momentum built an AI-native revenue orchestration platform that turns customer conversations into structured CRM data, Slack alerts and agent workflows. Salesforce completed its acquisition on March 2, 2026 (Salesforce), and its conversation product now reads "Conversation Intelligence, powered by Momentum." If you compare Momentum with Gong today, you are really comparing Gong with Salesforce's roadmap.

Is "more AI" enough?

No. Adding agents and summaries to a transcript makes post-call work faster, but it does not change the moment that decides most deals: the buyer's question, live. "More AI" is a feature count. What changes outcomes is where the AI sits in the sale and what it knows.

Use these four questions to cut through any demo:

1. When does the AI act? Before the call (prep), during the call (help) or after it (notes, CRM, coaching). Most tools in this comparison are strongest after.

2. What context does it use? A single transcript, or a connected model of your deals, objections, competitors and wins that improves with every call.

3. Who sees it? Manager dashboards change reports. Output the rep sees on the call changes conversations.

4. How are actions governed? Agents that write to the CRM need previews, approvals and audit trails.

Analysts are asking the same thing. Forrester's Q3 2026 Wave on revenue orchestration named revenue context and agent lifecycle management (governance, oversight and auditability) among its three main findings (Forrester).

Why does architecture matter more than features?

A transcript-centric tool treats each call as a document: analyze it, tag it, summarize it, move on. Insight lives in dashboards and flat CRM fields. That works for reporting, but every new call starts from zero.

A graph-centric tool treats calls as connected evidence. Objections, competitors, decision makers and the answers that won are entities tracked across every deal. The next rep facing the same objection inherits what worked, and AI agents act on structure rather than on loose text. That is the difference between a cheaper recorder and a system that compounds.

Where Proshort fits

Proshort is built on that second model. Its contextual graph connects playbooks, calls, objections, competitors and wins and is updated after every call. When the buyer asks, Aria walks the graph in real time and hands the rep a grounded answer with sources, during the call, privately. The buyer sees a normal meeting.

The same graph powers the rest: Ask Aria answers questions across every deal and call, AI agents run on every meeting with a preview run before they go live, and CRM updates happen after the rep's OK. You can ask about calls, deals and accounts from the Proshort app in ChatGPT or from Claude (MCP). Pricing is $75 per rep per month, with Aria Live at $3 per call hour on the calls you choose.

"For me, this becomes a very overarching sales AI use case where it is not about call recording. It is about using AI to manage and structure my mailbox, my communications tied to a particular deal." Amit Tomer, VP of Strategic Sales, Aviz Networks (read the Aviz Networks case study)

Where another tool fits better: if CRM admin is your only pain and budget is tight, Sybill's free tier is a reasonable start. If Salesforce is your whole stack, its Momentum-powered product keeps you with one vendor.

How should you evaluate Gong against AI-native tools?

• Run a two-week pilot on the same team and the same deals, not separate demos.

• Score each tool on the four questions above, with evidence from real calls.

• Check what happens to your history: Proshort migrates existing Gong, Chorus or Fireflies recordings during onboarding; ask others the same.

• Price the full contract: platform fees, seats for managers and RevOps, and live-call usage.

Frequently asked questions

Is Oliv a good alternative to Gong?

Oliv suits teams that want agents to run CRM hygiene, deal follow-through and forecasting, and that value published pricing. Gong is broader and more established. Pilot both on the same deals and check which agent actions your team actually trusts.

How does Momentum compare with Gong now that Salesforce owns it?

Salesforce completed its acquisition of Momentum on March 2, 2026, and Momentum now powers Salesforce Conversation Intelligence. For Salesforce-first teams it keeps calls and CRM with one vendor; for everyone else, Gong or an independent tool avoids depending on the Salesforce roadmap.

What are alternatives to Sybill for call summaries and follow-ups?

Proshort drafts the recap in the buyer's own words with action items, owners and the next step, and nothing goes out until the rep reviews and sends it. Gong and Fireflies.ai also write summaries; compare how each handles CRM updates and approvals.

Are AI-native tools cheaper than Gong?

Sybill, Oliv and Momentum publish pricing, while Gong quotes privately with a per-user license plus a platform fee. Compare total contract cost, including platform fees and add-ons, rather than list prices alone.

Do any of these tools help reps during the call?

Oliv's blog describes a voice agent with real-time prompts during calls; Gong, Sybill and Momentum focus on before and after. Proshort's Aria Live is built for the live moment, with private, sourced answers that only the rep sees.
