Identity

• Founded: [UNKNOWN - not disclosed on vendor site]
• HQ: [UNKNOWN - not disclosed on vendor site]
• Legal entity: Vivun, Inc. [VENDOR-CLAIMED - vivun.com]
• Funding: Undisclosed amounts; backers include Menlo Ventures, Salesforce Ventures, Tiger Global, Unusual Ventures, Atlassian Ventures, and Accel [VENDOR-CLAIMED - vivun.com/about]
• Headcount: [UNKNOWN]
• Recent news (last 12 months): 2025 launch of Hero® - described as "the AI Teammate built to help sellers win"; available to individuals and enterprise customers with a complimentary trial option [VENDOR-CLAIMED - vivun.com]
• Archetype: AI teammate for sales engineers and presales teams - purpose-built for the SE/presales motion with structured reasoning over deal state, stakeholder dynamics, and competitive context

Total score: 31.7 / 100

Scoring: equal-weight mean of 6 dimensions × 100, less pricing-transparency penalty (hard = 10 pts).

• Stage fit:
• Foundation (<$5M ARR): no - Vivun's presales/SE motion requires a sales engineering function to exist; Foundation-stage companies typically do not have dedicated SEs
• Pilot ($5-$50M): conditional - Pilot-stage SaaS companies with 1-2 SEs doing technical discovery may benefit from Hero® to formalize deal qualification; the complimentary trial lowers evaluation cost, but meaningful value requires a structured SE process
• Scale ($50-$500M): yes - the primary fit; Scale-stage companies running formal presales processes with 3+ SEs who need AI support for deal qualification, competitive-context reasoning, and technical discovery automation
• Optimization ($500M+): yes - SOC 2 Type 2, ISO 27001, ISO 42001, and GDPR posture is enterprise-grade; large companies with global SE teams will find the compliance posture sufficient for procurement requirements
• One-line verdict: A purpose-built AI tool for the sales-engineering and presales motion that Apollo, Salesloft, and Outreach do not address, with SOC 2 Type 2 / ISO 27001 / ISO 42001 / GDPR coverage; hard-gated pricing and no public customer references make total cost and fit difficult to verify without a sales conversation.

Headline numbers

Dimension scores

Equal-weight scoring - 6 dimensions, each 16.7% of the base score.

Pricing detail

Vivun does not publish pricing. The homepage product launch for Hero® routes to a "Try Hero free" complimentary trial with no tier or price disclosure. No historical pricing page is available. Buyers should expect enterprise-style custom pricing consistent with the Menlo Ventures / Salesforce Ventures / Tiger Global backing and SOC 2 / ISO 27001 compliance posture.

Integrations

From D1 catalog [MEASURED - D1, yardstick-data]: - Salesforce Sales Cloud Einstein - Salesforce Einstein Copilot

From vendor site [VENDOR-CLAIMED - vivun.com]: - Salesforce (primary CRM integration - SE/presales workflows live in Salesforce)

Notable: Vivun's integration footprint in D1 is Salesforce-only. This reflects the product's focus on the presales motion, which runs primarily through Salesforce Opportunities and custom SE objects. Buyers on HubSpot or other CRMs should verify compatibility directly with sales. [MEASURED - D1, yardstick-data]

Editorial assessment

Vivun sits in a category that larger sales engagement platforms have not entered: the AI layer for sales engineering and presales. Apollo, Salesloft, Outreach, and the autonomous AI SDR cohort are built for top-of-funnel outbound; none of them address the technical discovery, demo-flow structuring, and deal-qualification work that SEs perform during mid-funnel. Vivun's Hero® product - described by the company as "structured reasoning over persistent world models" - targets that motion. The compliance posture is broad for a company of this scale: SOC 2 Type 2, ISO 27001, ISO 42001 (AI-specific management systems), and GDPR coverage together address procurement requirements at large enterprise and regulated-sector buyers. The investor list (Menlo Ventures, Salesforce Ventures, Tiger Global, Unusual Ventures, Atlassian Ventures, Accel) indicates backing from enterprise-software-focused investors.

The deliverability infrastructure score of 0/4 is a category artifact, not a product failure: deliverability (email domain reputation, DNS warmup, inbox placement) is not a relevant dimension for a presales-motion product that does not send cold outbound email. The 0/4 score depresses the base total but should not be interpreted as a product deficiency. The meaningful weaknesses are cost-per-seat efficiency (1/4, reflecting full pricing opacity) and the absence of named customers on the public site - both of which make it impossible to benchmark TCO or verify customer outcomes without entering a sales process.

The 2025 Hero® launch includes a complimentary individual trial, which lowers the evaluation barrier and indicates the vendor will let single SEs use the product before an enterprise rollout. Buyers at Scale-stage companies with 3+ SEs should start with the individual trial before committing to an enterprise contract. [VENDOR-CLAIMED - vivun.com]

Best for

• Stage: Scale ($50-$500M ARR) and Optimization ($500M+)
• Company profile: B2B SaaS companies with a dedicated sales engineering or presales function (3+ SEs) who want AI support for deal qualification, technical-discovery structuring, competitive context, and stakeholder mapping; enterprise companies with SOC 2 / ISO 27001 procurement requirements; Salesforce-primary organizations whose SEs manage Opportunities and custom SE objects inside Salesforce
• Skip if: The company does not have a sales engineering or presales function; buyers who need published pricing for internal budget approval before entering a sales process; organizations on HubSpot or other non-Salesforce CRMs (verify compatibility first); Foundation or Pilot-stage companies without dedicated SEs

Right-of-reply

Vivun received this tear-sheet seven calendar days before publication of the Yardstick Research 2026 Yardstick Report, including all measured numbers, sample outputs, and editorial assessment. Vivun was given the opportunity to flag factual errors - incorrect pricing, misquoted feature availability, outdated screenshots, factual misstatement in the editorial assessment. Vivun was not given the opportunity to request a score revision, dispute the rubric or its weights, withdraw from inclusion, negotiate ranking placement, or suggest changes to the editorial assessment beyond factual correction. Where a vendor flagged a factual correction, the correction was applied if verified and noted here; where a vendor disputed scoring, the dispute is recorded in the appendix but the score stands. Silence from the vendor during the right-of-reply window was treated as no objection.
