You: Should I price the launch tier at $9 or $29?

3
Fonda: Benchmark: competitors are $39–$79 for equivalent feature sets.

Say it replaced a call

The loneliest role in the world.

  • Making big calls at 11pm, alone
  • Generic ChatGPT without context
With Fonda
  • Strategic partner available now
  • Already knows your plan and metrics
  • No hourly rate, no scheduling
  • Calibrated to your risk profile
  • Remembers every decision you've made

Capabilities

Everything you need, nothing you don’t.

Knows your business deeply

Plan, financials, traction, and past decisions all in context — not generic advice pulled from the open web.

Devil's advocate by default

We flag weak assumptions, unit-economics red flags, and strategic risks before they cost you runway.

Chat about anything

From pricing to hiring — get a real perspective tied to your data.

Daily direction

What to do today, this week, this quarter — prioritized.

24/7 availability

Late-night decisions don't have to wait for Monday standup.

Action-oriented

Every chat ends with a clear next step, not a long essay.

Learns your voice

The longer you use it, the more it sounds like the partner you'd hire.

Memo mode

Turn a 20-minute conversation into a clean decision memo for your team.

Built for

Teams of every shape.

Solo founders

The thinking partner you'd hire if you could afford one.

Consultants

A second brain for every client engagement.

Small teams

Aligned advice across co-founders and early hires.

Boards

Briefings that surface the question your board will actually ask.

Loved by founders

They shipped. So can you.

It's like having a Stanford MBA on Slack at 11pm. I don't make a single big decision without running it past Fonda.

M
Maya R.
Solo founder, SaaS

The feedback is harder than my advisors — and usually more right. Worth every cent.

T
Tom B.
Seed founder

It caught a flaw in my unit economics that would've killed the round. I owe it a cap-table allocation.

Jordan L.
Pre-seed founder
