Autonomous AI Workforce for Solo Founders Running a business solo means wearing every hat: marketer, support rep, salesperson, accountant, and ops manager. AI promised to solve this, but founders ended up stitching together single-purpose tools and managing complex workflows. Sistava takes a...

As answered by people managing Coderbyte and Sistava.
Sistava's answer:
Large language models (Claude, GPT-4-class) for the agent reasoning layer. Multi-agent orchestration with LangGraph. Persistent memory stores so each AI employee remembers context across sessions and tasks. Temporal for scheduled work. Django on the backend, React on the frontend. Multi-tenant infrastructure with strong isolation between accounts.
Sistava's answer:
Sistava isn't an AI tool you operate. It's a workforce you brief.
Other products want you to learn another interface, configure another integration, automate one more workflow. Sistava ships you a team: a marketer, an HR rep, a sales rep, a support agent, an accountant. Each AI employee has a role, a memory, a set of duties, and a track record you can review.
You stay out of the weeds. They run the business while you build it.
Sistava's answer:
Most AI-agent platforms expect you to build the agents yourself: design the workflows, write the prompts, wire the integrations, debug the loops. That's a second job, and most solo founders don't have time for it.
Sistava ships specialized AI employees ready to work, with persistent memory and clear duties. Brief them like you'd brief a new hire: tell them what to do, set expectations, check the output.
It replaces a stack (CRM, helpdesk, project tracker, marketing automation) plus contractors (VAs, writers, ops). Built for solo founders, not enterprise teams.
Sistava's answer:
Solo founders, indie hackers, and tiny teams who can't justify hiring humans yet but are drowning in operational work.
Non-technical founders especially. The "jack of all trades" founder who needs a team to run the business while they build it: marketing, customer support, sales follow-ups, bookkeeping, hiring admin, ops.
Not for enterprise IT or for engineers who want to build their own agents. For people who want the work done.
Sistava's answer:
Sistava is built by Sista AI, an Amsterdam-based AI software company.
The team spent years watching solo founders drown in operational work that shouldn't need their attention. The same founder doing the marketing, the customer support, the sales follow-ups, the accounting, the hiring admin. Drowning in a stack of single-purpose AI tools that each promise to help but each demand more configuration.
Sistava is the answer: hire AI employees the way you would hire humans. They show up, do the work, hand off across functions, and learn over time. The founder stays in the loop on what matters and out of the weeds on what doesn't.
