Bay Area math is brutal: a senior engineer costs USD 200K-plus a year before equity, and every VC-backed founder knows how fast that eats a raise. GTS Infosoft is the other option — a senior India studio that builds AI/ML products, SaaS platforms and mobile apps from around USD 20 an hour, with a shift that overlaps your Pacific morning and a US office in Kirkland, Washington for contracts and coordination.
And we're not new to the AI wave — we've been shipping Python and OpenAI-backed features into production since before it was a pitch-deck requirement. MVPs that had to survive a demo day. SaaS platforms that grew from ten users to ten thousand. Integrations, RAG pipelines, mobile companions to web products. Two hundred fifty-plus apps over 16 years, and plenty of them started exactly where you are: pre-seed, tight budget, no time to waste.
To be clear about what we are: an India-based studio, headquartered in Jodhpur, ISO 9001:2015 certified, working with you remotely. No SoMa address, no local markup. What you get instead is a dedicated senior team, documented process, code you own outright, and a burn rate your next investor update can be proud of. Founders who've tried freelancer roulette tend to appreciate the difference.

What We Build for Bay Area Startups
AI and ML products
LLM features, RAG pipelines, chatbots, recommendation engines and computer vision — built in Python with OpenAI and meant for production, not demos.
SaaS platforms
multi-tenant B2B SaaS, dashboards, billing and admin tooling on MERN and MEAN stacks, architected so it holds up as you grow.
MVP-to-scale builds
fast, investor-ready MVPs that grow into solid platforms as you raise and add users.
Mobile apps
native iOS and Android in Swift and Kotlin, or cross-platform Flutter and React Native when speed matters more.
Integrations
payments, auth, analytics, CRM and third-party APIs wired into whatever Bay Area stack you're already running.
Why San Francisco Companies Choose GTS
West Coast timezone overlap
our morning shift lines up with the San Francisco start of day, so standups, demos and quick decisions happen live.
Runway-friendly cost
senior offshore engineering from around USD 20 per hour — a fraction of what Bay Area salaries or agencies run.
Real AI/ML depth
we've shipped LLM, generative AI and ML features that run in production, not just in prototypes.
Senior dedicated teams
experienced architects and engineers, ISO 9001:2015 QA behind them, and clear English communication the whole way.
Industries We Know in the Bay Area
Developer tools and infrastructure
Dashboards, CLIs, docs sites and billing for devtools startups. Your users judge polish harder than anyone else's, and we build with that audience in mind.
Biotech and life sciences
South San Francisco's labs need LIMS integrations, sample tracking and internal tooling more than they need another landing page. We build the software around the science, remotely and affordably.
Climate and energy tech
Monitoring dashboards, utility-data integrations and emissions-reporting tools for climate startups that need engineering output without Bay Area burn rates.
Fintech and payments
Ledger-backed features, payout flows and bank-API integrations from a team that's shipped fintech work for clients in India, the US and Australia.
Consumer marketplaces
Two-sided marketplaces with matching, payments and trust features — the category San Francisco keeps reinventing, and we keep building.
How We Work With You
MVP-first approach
we scope a lean, investor-ready build first, then expand it sprint by sprint as milestones land.
Flexible engagement models
fixed-scope projects, dedicated teams or staff augmentation — pick what fits your stage and budget.
Full transparency
weekly reports, shared boards and shared source control, so status and spend are never a mystery.
Smooth onboarding
discovery, a fixed estimate and a delivery plan before we write code, plus full IP and code handover.

Frequently Asked Questions
Do you have an office in San Francisco?
No San Francisco office, no. Bay Area clients work with our India studio remotely, coordinated through our US office in Kirkland, Washington, and our morning shift overlaps your West Coast start of day.
How does your pricing compare to hiring in the Bay Area?
AI-accelerated delivery starts around USD 20 per hour — far below Bay Area engineering salaries or agency rates. Early-stage teams stretch their runway and still keep senior people on the build.
Can you take a product from MVP to scale?
Yes. We start with a lean, investor-ready MVP and build it out into a production-grade platform as you raise and add users. The same senior team stays on the codebase the whole time.
How real is your AI/ML experience?
Real. We ship LLM and generative AI features, RAG pipelines, chatbots and ML models into production with OpenAI and Python — not demos. AI work gets scoped to measurable outcomes, never hype.
How do you handle IP, NDAs and data security?
NDAs get signed before anything is shared. Full IP and source ownership go to you, and we run ISO 9001:2015 controls: secure repositories, managed access and careful data handling.
