The San Francisco Market

Why mobile matters in San Francisco

San Francisco is the global centre of technology innovation. SF startups are benchmarked against the best products in the world — average is not an option. Every mobile product that comes out of this market is compared to the gold standard of consumer and enterprise software.

Why Orbilox

Why businesses choose us

1

Startup-Speed Delivery

We understand startup timelines. Our fastest MVP-to-launch was 9 weeks. We move fast without accumulating technical debt.

2

Investor-Ready Code Quality

Technical due diligence is part of fundraising. Our codebases are clean, tested, and documented — no nasty surprises during a technical audit.

3

AI & ML Integration

We integrate LLMs, recommendation engines, and ML models into mobile apps — from Claude API to custom PyTorch models.

4

Bay Area Network Alignment

We have supported companies through YC batches and Series A fundraises, and understand the product expectations of SF-based VCs.

How We Work

From first call to live product

1

Lean Discovery

Fast alignment on MVP scope, core user journey, and success metrics. We move from first call to spec in 72 hours.

2

Architecture Review

We define the technical architecture before writing code — choosing the right trade-offs for your current stage and future scale.

3

Design & Prototype

Interactive Figma prototype delivered within the first sprint. Validated with real users before development begins.

4

Continuous Delivery

Weekly releases to TestFlight/Firebase. You can user-test every sprint increment before it goes to the App Store.

5

Scale Planning

Post-launch, we document architecture decisions and create a scaling roadmap so your next engineering hire can hit the ground running.

Frequently Asked Questions

Do you work with San Francisco startups?

Yes — SF and the broader Bay Area is one of our strongest markets. We work well with YC-backed companies, VC-funded startups, and bootstrapped founders with high product standards.

Can you build an AI-powered mobile app?

Yes. We integrate LLMs (Claude, GPT-4), recommendation engines, and computer vision into mobile apps. We have shipped AI-native mobile products across multiple categories.

Will our codebase pass technical due diligence?

Yes. We write code to a standard designed to survive due diligence — full test coverage, clean architecture, no hardcoded secrets, and thorough documentation.

How do you handle rapid pivots, which are common in SF startups?

We build for flexibility — modular architecture, feature flags, and clean service boundaries so pivots are surgical, not painful rebuilds.
