> AI-native custom software development for US small and mid-sized businesses, priced per deliverable.

SixHelix builds software products and integrations for US small and mid-sized businesses using modern AI-native development. Work is scoped into discrete, demoable deliverables — each with a fixed price agreed upfront. Clients pay per accepted output, not by the hour or by AI token consumption.

## How it works

- Describe your project in the Prompt Composer on the homepage
- SixHelix breaks it into deliverables (modules, integrations, agents, screens)
- Each deliverable gets a fixed price and timeline before work starts
- You review and accept each milestone; payment releases only on acceptance
- Scope changes are re-quoted the same way — no open-ended change orders

## For companies

Small and mid-sized US businesses that need custom software — internal tools, customer-facing apps, AI-integrated workflows, or API integrations — without the risk of uncapped hourly billing.

Supported stacks: React, Node.js, Python, and LLM-integrated workflows (Claude, OpenAI, Anthropic APIs).

## For experts

Experienced software engineers and AI builders can join SixHelix to take on well-specified bounty tasks. Each task has a defined spec, acceptance criteria, and fixed bounty. No ambiguous briefs, no scope creep.

Supported stacks: React, Node.js, Python, and LLM-integrated workflows (Claude, OpenAI, Anthropic APIs).

Open task categories: Web Development (HR portals, dashboards, ATS), Agent Skills (sourcing, screening, scheduling, interviewer, and orchestrator agents), Integration (accounting sync, statutory e-filing, benefits, messaging, calendar, SMS, bank disbursement), Authentication (RBAC, SSO, MFA, SCIM, multi-tenant isolation), Backend (multi-country payroll engines for Indonesia, Singapore, Thailand, Vietnam, Malaysia, Philippines), MCP & Harnesses (Model Context Protocol servers, evaluation harnesses, tool schema registries).

Bounties range from $900 to $3,400 per task. Each task includes a written spec, test suite, and fixed bounty paid on acceptance.

## Pricing model

Output-based. Fixed price per deliverable. No hourly rates, no retainer, no token fees. The price you approve before work starts is the price you pay.

## The name

SixHelix is named for the six strands every working software product is woven from: App Development (portals, dashboards, flows), Agent Skills (autonomous AI agents plus orchestrators, evaluators, and guardrails), Integration (two-way connectors into accounting, calendars, messaging, and banks), Authentication (RBAC, SSO, MFA, SCIM, audit), Backend (deterministic engines such as payroll and disbursement), and MCP & Harnesses (Model Context Protocol servers and the test harnesses that verify everything). Every project is scoped, priced, and shipped across these six strands.
