A demo in many languages: someone asks whether to sell their company to a bigger competitor offering $2.4M. Their AI chief of staff recalls what she knows and seats four AI experts, each on a different AI model: The CFO and The Lawyer are conditional, The Strategist is against, The Skeptic is for. The board’s call: don’t accept yet; counter at $3.1M with 80% cash at closing, and get a second offer within 30 days. On Thursday she checks in: did the second valuation come in?

The difference
Not a chat reply.
A decision you can act on.
A bigger competitor offered $2.4M for my company. Do I sell?
That’s a big decision, and there are many factors to consider. First, think about your long-term goals and whether selling aligns with them. You should also look at the valuation: is $2.4M a fair price for your company? It may help to consult a financial advisor.
Other factors include your team, the market, timing, tax implications and your personal circumstances. Ultimately, the right choice depends on your situation…

Questions
Fair questions.
Straight answers.
What people ask before they bring SynthBoard their first hard call.
What is SynthBoard?
SynthBoard is an AI chief of staff with a bench of 24 AI experts: a CFO, a skeptic, a lawyer and more. She answers what she can, brings in one named expert when a call needs judgment, or seats a board to argue it out. You get the call, who disagreed, and a first step with a date.
How is SynthBoard different from ChatGPT or Claude?
A single chat gives you one voice, and it tends to agree with you. SynthBoard seats named experts who hold positions, including one whose job is to argue against the obvious answer. Every memo shows the dissent and what would change the call. It also keeps your facts with their sources, so nothing starts from zero.
Who is SynthBoard for?
People who make hard calls without a leadership team around them: founders, solo operators, consultants, small-business owners and managers. It handles personal decisions too, like a job offer, a move or whether to sell a home. Most people start with the one question that’s been sitting with them.
How much does SynthBoard cost?
SynthBoard is free to start: 250 credits when you sign up and 150 every month, no card needed. Pro is $20 a month (2,500 credits), Max $50 (7,000) and Ultra $99 (15,000), and paying yearly gives you two months free. One credit is $0.01. Talking to the chief of staff is free within a daily allowance.
How do SynthBoard credits work?
Every expert or board arrives as a card that shows the most it can cost before anything runs: up to 65 credits for one expert, up to 135 for a board of three on Free. You pay only for what the room actually uses, and a card never bills above its number. Small pieces she makes for you (a forecast, a table from your tools, a read of a stack of photos) come out of a monthly allowance without asking (up to 400 credits on Pro); rooms and boards always show their price first. Plan credits reset monthly; credit packs never expire.
Is my data private with SynthBoard?
SynthBoard reaches model providers only through their business APIs, under terms that don’t let them train on what it sends, and it never sells your data. Every fact she keeps shows where it came from, any fact can be forgotten, and “Start fresh” wipes everything, with 24 hours to undo. Details are in the Privacy Policy.
What if SynthBoard’s experts are wrong?
They can be: SynthBoard’s experts are AI. That’s why an expert asks you first when the answer turns on something only you know, and why every memo shows how confident the board is, what would flip the call, and who disagreed. Treat it as a sharp second opinion, not legal, financial or medical advice.
What can SynthBoard do in my tools?
SynthBoard connects to Notion, Google Docs, Slack, Linear, Gmail and dozens more. Every connection starts read-only. Each write is a preview on a priced card that you confirm before anything changes, and an email is saved as a Gmail draft for you to send yourself. Reading is on every plan; writing is on Pro and above.
Which AI models does SynthBoard use?
SynthBoard seats its experts on models from OpenAI, Anthropic, Google, xAI and Mistral, and spreads a board across labs so the voices don’t all think alike. Live web research grounds the facts. Free runs standard models, Pro adds premium ones, and Max and Ultra add frontier models.
Which languages does SynthBoard speak?
SynthBoard answers in the language you write in. The experts, the room cards and the chief of staff’s notes all come back in it, from Portuguese and Spanish to Japanese and Hebrew, and Hebrew and Arabic read right to left throughout. You can switch languages mid-conversation.
Can I change or cancel my SynthBoard plan?
Yes, any time. Upgrades apply immediately, with the difference prorated; downgrades take effect at the end of your billing period. If you cancel, your paid plan keeps running until the end of the period you’ve already paid for. Payments and invoices are handled by Paddle, SynthBoard’s merchant of record.
Can I use SynthBoard from Claude, ChatGPT or Cursor?
Yes. SynthBoard has an MCP server, so you can start a board, ask an expert or read a memo from Claude, ChatGPT, Cursor and other MCP clients, on every plan. Free runs one session at a time over MCP; paid plans run several in parallel. There is also a REST API with webhooks.
