Sinatra
Sinatra is a hosted autonomous coding agent that works from the issue tracker a team already uses. It takes a Linear issue or GitHub issue, reads the codebase, writes and tests the change in an isolated sandbox, and returns a reviewable pull request while leaving merging to humans.

- Software engineering teams using GitHub
- Teams using Linear for issue tracking

Products & Services
A managed coding agent triggered by assigning a Linear issue or adding the sinatraai label to a GitHub issue. It checks out the repository into a task-specific sandbox, plans when needed, implements the change, runs tests, self-reviews the diff, and opens a draft pull request.
Install the Sinatra GitHub App, enable repositories, add a .sinatrarc test command, and apply the sinatraai label. Sinatra opens a branch and draft PR, posts progress on the issue, reacts to CI failures, responds to review-change requests, and never merges.
Connect a Linear workspace, assign or @-mention Sinatra on a ticket, and receive progress in a Linear agent session and a linked GitHub pull request. Repository selection can use an explicit Repo: owner/name line or infer from ticket context and enabled repositories.
Market Position
Sinatra positions itself as a tracker-native background coding agent rather than an IDE surface: it is triggered by GitHub issues or Linear assignments, returns a reviewable PR, supports BYOK and existing Claude or ChatGPT subscriptions, and charges a flat $20 per workspace member with no model markup. Its official alternatives page compares it with GitHub Copilot, Codex, Jules, Cursor, Claude Code, Linear, Kiro, Devin, OpenHands, Factory, Tembo, and others. The product emphasizes human review and a hard product boundary at the pull request rather than autonomous merge or deployment.
Leadership
Founders
Behroz Saadat
Software engineer and solo founder. Mooky identifies his background as 15 years including Block (Cash App), Amazon, and AWS; Sinatra's About page identifies him as the founder.
Executive Team
Behroz Saadat
Founder
Software engineer with a background including Block (Cash App), Amazon, and AWS; Mooky describes him as President & Principal Engineer there.
Founding Story
Behroz Saadat started Sinatra after seeing coding agents become good at writing code while the surrounding work remained manual: reading the ticket, opening a branch, driving the agent, and shepherding the result into a reviewable pull request. The initial vision was an agent triggered from the tracker where teams already work, with transparent model costs and a human-controlled stopping point at the pull request. Crunchbase additionally describes the early motivation as helping his wife ship website fixes.
Business Model
Revenue Model
Flat per-workspace-member subscription for orchestration and hosted sandboxes, with model usage either supplied through the customer's own key/subscription or passed through at provider rates when using Sinatra's managed access. Enterprise is sold as a custom annual contract.
Pricing Tiers
Five tasks per day with the customer's own API key or personal subscription; up to one task per day on Sinatra's keys within the same five-task pool; no credit card.
Includes members who only review; no daily task cap and no LLM markup; cancel anytime.
Custom security requirements, support, and contract terms.
