A team you want to involve again and again

The Toimi team approached the project systematically — not only from a visual design perspective, but also in terms of deeper meaning and positioning. Together, we redefined how we talk about our products and communicate their value to clients. The result exceeded expectations: a thoughtful brand identity and a modern, user-friendly website. These changes have already influenced how the company is perceived — clients and partners now respond to Brealit differently.

FAQ

If you still have questions, email us at info@toimi.pro or fill out the contact form below.

Do you work with San Francisco-based startups and tech companies?

We work with companies at every stage: from pre-seed founders coming out of Y Combinator, Techstars, or building in SoMa co-working spaces, to growth-stage teams scaling AI, SaaS, and developer tool products. Whether you need an MVP to raise your first round or a production-grade platform to support 100K+ users, we understand the pace and technical expectations of SF's ecosystem.

What types of San Francisco businesses do you typically work with?

Our SF clients span the full range of the city's tech economy — from early-stage AI startups in the Mission and SoMa districts to established SaaS and fintech companies scaling from Series A to C. San Francisco has the highest startup density on earth — over 6,200 startups per 100,000 residents — and we work with founders and teams across AI/ML, developer tools, fintech, healthtech, biotech, and enterprise software. We also work with companies outside pure tech: e-commerce brands, professional services firms, and real estate platforms that need strong digital products to compete in the Bay Area's demanding market.

How much does web development or app development cost in San Francisco?

Every project is different, and we don't publish cookie-cutter rates. A landing page for a pre-seed startup and a full SaaS platform for a Series B company are fundamentally different in scope, timeline, and investment. We start with a free consultation to understand what you're building and provide a clear, tailored estimate. We offer flexible pricing models: fixed-price for well-defined scopes, monthly retainers for ongoing collaboration, and time-and-materials for products that evolve as they grow. San Francisco founders are used to transparency — and that's exactly what we deliver. No hidden fees, no surprise invoices.

How long does it take to build a website or app?

A custom business website typically takes 6–10 weeks from kickoff to launch. Web applications and SaaS platforms take 3–4 months. Mobile apps range from 3–6 months depending on features, integrations, and platform requirements. After discovery, we provide a detailed timeline with milestones — from design through development, QA, and deployment. In San Francisco, speed-to-market can determine whether you close your fundraise, capture a market window, or beat a competitor to launch. We structure our process to move fast without cutting corners.

Do I need to be located in San Francisco to work with you?

Not at all. While San Francisco is one of our key markets, we work remotely with clients across the Bay Area, California, and the entire US. SF pioneered the distributed team model — most of the city's best companies operate across time zones with remote contributors. Our collaboration happens through Slack, Zoom, Figma, and project management tools — the same stack SF tech teams already use daily. If you're local and prefer to meet in person, we're happy to accommodate. But remote doesn't mean distant — it means efficient.

What technologies do you use for San Francisco projects?

We build with the same modern stacks that SF's top startups use: React, Next.js, and Vue.js on the front end; Node.js, Python, and PostgreSQL on the back end; Flutter and React Native for cross-platform mobile. For San Francisco's AI-driven market, we also integrate with OpenAI APIs, custom LLM pipelines, vector databases, and AI/ML infrastructure — capabilities increasingly expected by investors and users alike. We work with Stripe, AWS, Vercel, Firebase, and other tools that are standard in the Bay Area ecosystem. We don't push one stack — we choose what's right for your product, your stage, and your team's long-term needs.

Do you build AI-powered products and integrate AI features?

Yes — and this is a core strength. San Francisco attracts over 50% of global AI funding, with companies like OpenAI, Anthropic, and hundreds of specialized AI startups concentrated here. We help companies integrate AI capabilities into web and mobile products — from chatbots and recommendation engines to data processing pipelines, LLM-powered features, and agent-based workflows. Whether you need to embed generative AI into an existing product, build an AI-native MVP, or create internal tools powered by machine learning, we have the technical depth to deliver. In a city where AI is the default expectation, we build products that meet that standard.

Can you help with UI/UX design, or only development?

We handle the full product lifecycle — from UI/UX research and prototyping to development, QA, and deployment. In San Francisco, design quality is a competitive requirement, not a nice-to-have. Users here are early adopters who use the best-designed products in the world every day — Figma, Linear, Notion, Arc. Your product's interface needs to meet that standard. We create user-centered designs informed by research, usability testing, and the design conventions that SF's tech audience expects. You don't need finished mockups — we can start from a rough idea.

Do you provide support and maintenance after launch?

Yes. Launching is the beginning, not the end. We offer post-launch support including performance monitoring, bug fixes, security updates, analytics optimization, and iterative feature development. Many of our SF clients start with a build engagement and transition into monthly retainers as their product grows and user feedback rolls in. In a market where companies like Stripe, Notion, and Figma set the bar for product quality — continuous improvement is not optional, it's expected.

Do you sign an NDA before discussing project details?

Absolutely. We're happy to sign an NDA before any detailed conversation. Many of our San Francisco clients are working on proprietary AI models, competitive SaaS products, or pre-launch ideas in a market where IP protection and discretion are critical. Confidentiality is standard practice from the first call.
