How we can help

Built for your stage of growth

We don't offer a menu of technologies. We solve specific business problems at specific stages — and we're honest when we're not the right fit.

Launch your product

Custom web and mobile development from zero to production. React, Next.js, iOS/Android. Built to scale, not just to demo.

⏱ Typically live in 8–12 weeks

Scale your team

Dedicated development teams embedded in your workflow. Senior engineers only. Your Slack, your Jira, your timezone — we adapt.

⏱ Team assembled in 2 weeks

Automate your operations

AI agents and workflow automation that replace manual processes. LLM integration, RAG pipelines, agentic systems — production-ready.

⏱ First automation live in 3–4 weeks

Modernize your stack

Legacy system migration, API-first architecture, performance overhaul. We rebuild without breaking what already works.

⏱ Scoping done in 1 week

AI capabilities

We don't bolt AI on. We architect for it.

Most agencies slap a chatbot on your website and call it AI. We build LLM pipelines, agentic workflows, and intelligent automation that replaces manual processes — and compounds value over time

* LLM Integration & Fine-tuning (OpenAI, Claude, Gemini, Llama)
* Agentic AI Systems — multi-step, tool-using autonomous agents
* RAG & Knowledge Base Systems — enterprise document intelligence
* AI Workflow Automation — custom pipelines at scale
* Computer Vision & Document Intelligence
* Predictive Analytics & Custom ML Pipelines

How we work

From idea to intelligent product

Lean, transparent, built for speed and quality. No fluff, no endless meetings.

01

Discover

Free 30-min technical call. We ask the right questions, understand your goals, and tell you if we're the right fit — honestly.

02

Design

Architecture, UI, technical scope. You see and approve the full blueprint before a single line of code is written.

03

Build

Agile sprints with weekly demos. Daily updates in your Slack channel. Senior engineers only — no handoffs to juniors.

04

Launch & Grow

We ship, monitor, and iterate post-launch. Ongoing support included. We're in it for the long run, not just the invoice.

Why 2FSoft

Not another outsourcing vendor.

We know what CTOs and founders worry about when hiring offshore teams. Here's how we're different — specifically.

Others say "experienced team"

Senior engineers only — no bait and switch

Others give vague T&M billing

Fixed-price milestones with weekly demos

Others outsource their AI work

Built-in AI expertise — not bolted on

The people

You're hiring people, not a company.

Meet the senior engineers who will actually work on your project — not just the sales team you'll never see again.

★★★★★

2FSoft did what no other agency promised — delivered a working AI agent in 4 weeks, and it's been running in production for 6 months without a single outage. The ROI paid for the project in the first month.

★★★★★

We needed a team that could move fast without breaking things. 2FSoft was in our Slack from day one, shipped weekly, and caught issues before we did. They feel like part of our team, not a vendor.

★★★★★

The RAG system they built processes our 10,000-document corpus in under 2 seconds. That was supposed to be impossible with our budget. They found a way. Would not hesitate to recommend.
