Overview
Apexon is a digital engineering services firm headquartered in Santa Clara, California, formed in 2022 through the rebranding of Infostretch and the combination of several Goldman Sachs-backed engineering businesses. The firm reports approximately 4,300 employees across 19 locations and 6 continents. Apexon is privately held by Goldman Sachs Asset Management and revenue is not publicly disclosed at audited-entity level; third-party estimates put the figure in a wide range, with one source citing approximately US$1.5 billion in 2026 — buyers should treat that figure with caution as no audited public disclosure supports it.
Quality engineering is one of four core practice pillars alongside experience, engineering, and data. Within QA, Apexon offers automation framework engineering, performance and reliability testing, application security testing, mobile testing including its long-standing device farm IP, and AI/ML quality engineering. The firm's heritage in Infostretch is mobile-first, and it retains strong references in healthcare, retail, fintech, and hi-tech software vendors.
Apexon suits enterprise and upper-mid-market buyers wanting integrated digital engineering with testing inside the same delivery team rather than as a separate practice. It is less aligned for buyers wanting a pure-play IV&V posture, large-scale package application testing on SAP or Oracle, or buyers requiring deep onshore senior bench in continental Europe.

Pricing verified May 2026 from public procurement data and reference checks; ranges vary by region and engagement structure. Indian delivery sits at the lower bound; United States and United Kingdom onshore work runs materially higher.
Strengths
- Integrated digital engineering and quality engineering — testing is delivered alongside build rather than as a separate practice
- Mobile-first heritage and substantial device-farm IP from Infostretch days; strong consumer-app and retail commerce references
- Material AI/ML and GenAI quality engineering practice, including prompt regression and model bias detection
- Strong healthcare and life-sciences testing footprint, including 21 CFR Part 11 and HIPAA-aware processes
- Goldman Sachs Asset Management ownership provides commercial discipline and capital for delivery-centre and acquisition activity
- Blended onshore-offshore model with United States senior partner presence on most large accounts
Limitations
- Private ownership and limited financial disclosure make scale and stability assessment difficult — third-party revenue estimates vary widely
- Brand visibility outside the United States, United Kingdom, and India remains thinner than tier-1 SI alternatives
- Less suited to buyers wanting a pure-play independent verification posture — Apexon also delivers build, which raises conflict-of-interest considerations
- Continental European bench is limited; Germany, France, and Nordics work typically pulled from the United Kingdom or India
- Mid-engagement attrition rates remain elevated; account-level retention is a recurring buyer feedback theme
