Sensiba LLP

About Sensiba LLP

Sensiba LLP is a Top 75 U.S. accounting and consulting firm with deep roots in the Bay Area technology ecosystem. Founded in 1977 in San Carlos, CA by Steve San Filippo and now headquartered in Pleasanton, CA, Sensiba has spent nearly five decades building expertise in audit, tax, and advisory services, with a particularly strong compliance practice serving venture-backed startups, SaaS companies, and growth-stage technology firms.

As a Certified B Corporation, Sensiba operates with an explicit commitment to people, community, and environmental responsibility. Rare in the CPA world, and genuinely differentiated among compliance auditors. The firm holds a ClearlyRated Best of Accounting 5-Year Diamond Award (2025, eighth consecutive year) for client satisfaction, reflecting consistent service quality across approximately 30 partners and 400+ professionals.

In April 2025, Sensiba acquired AssuranceLab, an Australian-headquartered cybersecurity audit firm with operations across the Americas, APAC, and EMEA. That same year Sensiba added six new partners on May 1 (the largest single-year partner expansion in firm history, with nearly half women) and acquired Everoot Consulting in July 2025, deepening its B Corp and ESG/sustainability advisory practice. The combined organization now serves 2,300+ clients globally across 15+ compliance frameworks, making Sensiba a meaningfully global player rather than a regional boutique. Post-acquisition, Sensiba ranks among the top 3 issuers of technology audit reports worldwide.

Monic Ramirez assumed the Managing Partner role in May 2026, succeeding John D. Sensiba, who continues as Partner and leads strategic initiatives. Jeff Stark (25+ years experience) heads the Governance, Risk and Compliance practice with deep expertise in SOC 1, SOC 2, and ISO 27001 for technology and VC-backed companies.

SOC 2 Focus & Differentiators (PRIMARY POSITIONING)

Sensiba has built its compliance practice around a core thesis: SOC 2 should be accessible, not overwhelming, especially for startups and growth-stage companies.

Fixed-Fee Pricing with 25–30% Savings:

Sensiba explicitly offers fixed-fee SOC 2 pricing at a 25–30% discount to competitors at comparable quality levels. This is not just marketing; their methodology is built around operational efficiency:

• AI-enhanced audit tooling for faster evidence analysis
• Deep integrations with compliance platforms (Drata, Vanta, Secureframe, Sprinto) to reduce manual work
• Specialized workflows for cloud-native environments (AWS, Google Cloud, Azure)
• Most reports delivered within 30 days after the audit period closes

AI-Enhanced Audit Process:

Sensiba actively uses AI tools throughout the audit lifecycle: faster data analysis, more efficient control gap identification, and a less disruptive client experience. This positions them ahead of traditional CPA firms still running paper-heavy engagements.

Experienced Senior Auditors (Not Contractors):

A specific differentiator Sensiba calls out explicitly: every SOC 2 engagement is led by an experienced senior auditor, not staffed out to junior contractors. Clients also receive a dedicated Client Success Manager for communication and coordination throughout.

PolicyTree:

Sensiba’s proprietary PolicyTree solution auto-generates tailored security policies as the foundation of a compliance program, reducing one of the most time-consuming prep activities for first-time SOC 2 clients.

Compliance Framework Coverage

SOC Audits:

• SOC 1 (financial reporting controls)
• SOC 2 Type I and Type II (primary offering)
• SOC 3 (public-facing summary reports)
• SOC for Cybersecurity

ISO Certifications (ANAB Accredited):

• ISO/IEC 27001 (Information Security Management)
• ISO/IEC 27701 (Privacy Information Management)
• ISO/IEC 27017 (Cloud Security Controls)
• ISO/IEC 27018 (Cloud Privacy)
• ISO/IEC 42001 (AI Management Systems)
• ANAB accreditation means Sensiba issues these ISO certifications directly, not just helping clients prepare. The ISO 42001 accreditation is particularly relevant for AI-driven companies needing formal AI governance certification.

Healthcare & Government:

• HIPAA compliance assessments
• HITRUST CSF assessor services
• CMMC Readiness for defense contractors

Emerging & International Frameworks:

• CSA STAR (Cloud Security Alliance)
• Essential 8 (Australian Signals Directorate cybersecurity framework)
• GS 007 audits
• CDR (Consumer Data Right) attestations (Australian open banking compliance)
• Privacy Attestations (GDPR-adjacent and US privacy frameworks)
• NIST Framework assessments

Security Services:

• Penetration Testing & Vulnerability Assessments (launched 2024)
• Third-Party Risk Management (TPRM) (launched December 2025; global enterprise service)

Blended Audits:

Sensiba specifically promotes combined audit engagements, such as SOC 2 + ISO/IEC 27001 in a single engagement using shared evidence. This reduces duplicate work and “audit fatigue” for clients pursuing multiple frameworks simultaneously.

AssuranceLab Acquisition (April 2025): Global Expansion

The acquisition of AssuranceLab represents a significant strategic shift:

What AssuranceLab adds:

• Operations across Americas, APAC, and EMEA (previously Sensiba was primarily U.S.-based)
• 2,300+ combined startup and tech-driven enterprise clients globally
• Deep technology-forward audit methodology and proprietary tooling
• Australian-specific frameworks (Essential 8, CDR, GS 007)
• Additional penetration testing and cybersecurity consulting capabilities

Continuity commitment: Clients see the same teams. No reintroductions, no disruption. What changes is expanded geographic coverage and framework depth.

Shared B Corp status: Both firms hold Certified B Corp status, a rare values alignment that made the acquisition culturally coherent rather than a purely financial transaction.

Platform & Technology Integrations

Sensiba explicitly supports major compliance automation platforms:

Platform	Integration Type
Drata	Evidence collection, control mapping
Vanta	Evidence collection, control mapping
Secureframe	Evidence collection, control mapping
Sprinto	Evidence collection, control mapping
PolicyTree	Proprietary policy generation (Sensiba-built)
ShareFile Portal	Secure audit evidence and report delivery

This breadth of integration matters for startups already using a GRC platform; Sensiba won’t require switching tools or running parallel workflows.

Pricing & Timeline

SOC 2 Pricing:

Engagement	Cost Range
Type I	$15,000 – $35,000
Type II	$20,000 – $50,000

Sensiba explicitly offers fixed-fee pricing (no hourly surprise billing) at a claimed 25–30% discount versus comparable competitors. This positions them below Big 4 and Top 25 firm costs while maintaining peer-reviewed CPA quality.

Timeline:

• Total engagement: 4–10 months (including observation period for Type II)
• Report delivery: Within 30 days after close of audit period (most engagements)
• Response time: 24–48 hours

Pricing Philosophy:

“We believe that SOC 2 should be attainable for any business, and our pricing reflects this. Our approach isn’t a one-size-fits-all; we tailor the offering (and price) to suit your needs and stage of business.” (Sensiba SOC 2 Pricing Page)

Client Experience

Sensiba’s client satisfaction scores are consistently strong. Themes from public reviews and case studies:

Accessibility & Communication:

“The key is the simplification of the audit requirement. Sensiba speaks a language the customer can understand.” (Paul Lubik, PBR Solutions)

Responsive & Non-Disruptive:

“Throughout the observation period, Sensiba was responsive about providing context and validation where we needed it, and they completed the audit without wasting any time.” (Clario)

Startup-Friendly Process:

“Working with a company of a similar size and that offered startup experience was important to us. We were comfortable the Sensiba team was open to our questions, and they were very responsive.” (Lucidworks)

Streamlined Multi-Framework:

“I couldn’t be more pleased with the support from Sensiba. They expertly streamlined the SOC 2 Type 1 and Type 2 audits, making the process seamless and efficient.” (Weaviate)

Client Tenure: Multiple reviewers note 5–7+ year ongoing relationships, a strong signal of consistent delivery and client retention.

Competitive Positioning

Unique Differentiators:

1. Bay Area / VC Ecosystem Depth No other regional firm has as deep a footprint in the Silicon Valley startup and venture capital ecosystem. Sensiba’s relationships with VC firms, accelerators, and portfolio companies create warm referral channels and genuine industry pattern recognition for cloud-native B2B SaaS.

2. Fixed-Fee + AI-Enhanced Efficiency The combination of fixed fees, AI tooling, and compliance platform integrations creates a genuinely differentiated cost/quality profile, not just pricing competition, but structural efficiency.

3. B Corp Status = Values Alignment For ESG-conscious tech companies and those building trust with institutional customers, a B Corp auditor reinforces values alignment. Few CPA firms hold this certification.

4. Global Reach via AssuranceLab Post-acquisition, Sensiba can serve clients across Americas, APAC, and EMEA with local expertise in Australian-specific frameworks (Essential 8, CDR), relevant for globally expanding SaaS companies.

5. ANAB-Accredited ISO Certification (Including ISO 42001) Sensiba can issue ISO/IEC 27001, 27701, 27017, 27018, and 42001 certifications directly (not just advisory), enabling true combined SOC 2 + ISO engagements without involving a second firm. The ISO 42001 (AI Management) accreditation is a rare capability for companies needing formal AI governance certification.

6. Top 3 Technology Audit Report Issuer Globally Post-AssuranceLab, Sensiba ranks among the top 3 issuers of technology audit reports worldwide, reflecting the combined firm’s scale and specialization in tech-sector compliance.

Potential Limitations:

1. Not a Government/Defense Specialist Sensiba lacks FedRAMP 3PAO authorization, CMMC C3PAO status (only readiness, not assessment), and Facility Security Clearance. Defense contractors should look elsewhere (e.g., Schellman, A-LIGN).

2. Regional Concentration (Historically) Although the AssuranceLab acquisition added global reach in 2025, Sensiba’s deepest expertise and client relationships remain in the Bay Area / California tech corridor.

3. Mid-Market CPA Scale At approximately 30 partners and 400+ professionals, Sensiba is larger than boutiques but smaller than Top 25 firms. Companies needing simultaneous large-scale multi-entity financial audits alongside compliance may prefer a larger firm with more bench depth.

4. Newer Penetration Testing Practice Pen testing launched in 2024, with less track record than dedicated security testing firms or Schellman’s government-cleared pen testing capabilities.

Who Should Choose Sensiba

Best Fit For:

• VC-backed SaaS startups needing SOC 2 to unlock enterprise sales in 4–8 months
• Bay Area and Silicon Valley tech companies with existing VC firm relationships to Sensiba
• Cloud-native companies already using Drata, Vanta, Secureframe, or Sprinto wanting a compatible auditor
• Companies combining SOC 2 + ISO 27001 or ISO 42001 in a single engagement to save time and cost
• APAC-connected companies needing Essential 8, CDR, or GS 007 alongside US compliance
• ESG-aware organizations that value B Corp certification in their vendor chain
• First-time SOC 2 clients who want fixed-fee pricing, readiness support, and a non-intimidating process
• Healthcare technology companies needing HIPAA + HITRUST + SOC 2 bundles

Not Ideal For:

• Defense contractors needing FedRAMP, CMMC assessment (not just readiness), or classified system audits
• Large enterprises requiring Big 4 brand prestige or PCAOB-registered financial audits at scale
• Companies in non-tech industries (agribusiness, construction, restaurant) seeking SOC 2 (Sensiba serves these but it’s not their center of gravity
• Organizations prioritizing lowest absolute price: boutique-only specialists (e.g., Prescient, KirkpatrickPrice) may undercut even Sensiba’s competitive rates for simple single-framework engagements

Bottom Line

Sensiba represents the best-positioned regional CPA firm for Bay Area tech startups and VC-backed SaaS companies seeking SOC 2. Their combination of fixed-fee pricing (25–30% below comparable competitors), AI-enhanced audit efficiency, deep integrations with all major compliance platforms, and 40+ years of technology sector relationships creates a genuinely differentiated offering.

The April 2025 AssuranceLab acquisition transforms Sensiba from a strong regional firm into a global compliance player serving 2,300+ clients across the Americas, APAC, and EMEA, particularly relevant for companies with Australian operations or global enterprise customers requiring multi-jurisdiction compliance.

The ANAB-accredited ISO certification body status enables true combined SOC 2 + ISO 27001, 27701, or 42001 engagements under one roof, a meaningful efficiency for companies pursuing multiple frameworks simultaneously. ISO 42001 (AI Management) certification is available directly from Sensiba, a capability few audit firms can offer.

As a Certified B Corporation, Sensiba attracts clients for whom ESG and values alignment matter beyond the audit itself, a differentiator that resonates with the values-driven startup and VC ecosystem they serve.

For startups, scale-ups, and technology companies who want a Top 75 CPA firm with startup sensibility: approachable auditors, fixed fees, fast delivery, and genuine platform expertise. Sensiba is a top-tier choice. The primary limitation is what they’re not: they’re not a government/defense specialist, not a Big 4, and not the lowest-cost option for the simplest possible SOC 2 engagement.
