Markovate vs Existek: overview

Markovate

Markovate was founded in 2015 and is led by CEO Rajeev Sharma, an AI veteran with 18+ years of experience who previously led AI initiatives at AT&T and IBM. Headquartered with a San Francisco address (some sources cite Toronto as an operating base), the company has grown to roughly 51 employees, including 50+ engineers described as 'certified AI engineers' (per company website), delivering custom AI agents, chatbot development, and cloud services for healthcare, retail, fintech, SaaS, and travel clients. Its small team size makes it a boutique play best suited to scoped generative AI or agent projects rather than large-scale programs.

Existek

Existek was founded in 2012 and operates with a 50–249 person team split across Bucharest, Romania and Vinnytsia, Ukraine, delivering custom software development, dedicated team staffing, and AI development services for clients in business intelligence, healthcare, oil & gas, and education. The company has been recognized by Clutch as a top developer in both Ukraine and Romania and holds a near-perfect 4.9 rating on the platform, with hourly rates of $50–$99/hr and a minimum project size of $25,000+. Its AI services page is comparatively general, offering less publicly documented technical specificity than boutique ML specialists in this list.

Markovate vs Existek: pros and cons

Markovate
+ CEO's 18+ years leading AI initiatives at AT&T and IBM brings genuine enterprise AI leadership experience to client engagements.
+ Focused service scope (AI agents, chatbots, generative AI) rather than a broad, diluted general-consulting offering.
+ Serves a wide industry spread (healthcare to travel) despite small team size, suggesting adaptable delivery patterns.
- At roughly 51 employees, capacity for multiple concurrent large engagements is limited.
- HQ location is inconsistently reported (San Francisco vs. Toronto across sources) — confirm the contracting entity directly.
- "50+ certified AI engineers" claim on a 51-person total headcount is a company claim worth verifying during vendor due diligence.
Existek
+ 4.9 near-perfect Clutch rating with top-developer recognition in both Ukraine and Romania.
+ $25,000+ minimum project size is more accessible than large enterprise-only vendors like EPAM.
+ 12+ years of operating history (since 2012) with dual-country delivery presence.
+ Serves niche industries (oil & gas, business intelligence) less commonly covered by boutique AI specialists.
- Publicly available technical detail on Existek's specific AI/ML methodology is thinner than boutique specialists like Neurons Lab or Provectus.
- AI development is one of several service lines (custom software, staff augmentation) rather than the firm's exclusive focus.
