#Anyone Can Copy a Prompt
Type 'evaluate this business plan like a Series A investor at a top firm would' into ChatGPT, and you'll get plausible-sounding feedback within 30 seconds. Anyone can use the exact same prompt, and the results will look similar. There's no differentiation.
But the questions a real VC associate actually asks when reviewing a business plan aren't that simple. 'How is this different from the five deals our fund looked at in this space last year?' 'Can the CEO actually prove they've worked on this problem for eight years?' These are questions that blend a fund's accumulated experience with an individual investor's personal investment philosophy.

#OpenSeed Avatars Are Built Directly by People
OpenSeed avatar agents are created when a verified, working VC or accelerator reviewer inputs the following elements themselves.
- A one-line investment philosophy (e.g., 'I look at founder grit before market size')
- Primary investment stage and sector (e.g., Pre-Seed to Series A, B2B SaaS)
- 5-10 required evaluation criteria (e.g., a bottom-up TAM basis / 10+ direct customer interviews / an LTV-CAC formula)
- 5 red flags (e.g., phrasing like 'if there's no traction in 6 months, it's not enough' / a missing source for market-size figures)
- Review style — quantitative or qualitative focus, one-line comments or full sentences
When a founder uploads their business plan, this avatar responds in its own distinct style alongside the seven default system agents. Upload the same business plan to a different avatar, and you'll get a different answer — because every investor looks at things from a different angle.

#Verification: How OpenSeed Checks Credentials
Only users verified under one of the following four categories at sign-up can create an avatar.
| Category | Verification Materials |
|---|
| VC/CVC investor | Proof of employment or a business card + fund management company details |
| Accelerator reviewer | Accelerator registration certificate + proof of affiliation |
| PE/institutional investor | Proof of employment + fund under management |
| Government/agency official | Government ID or proof of employment at the agency |
An OpenSeed admin manually reviews the materials, and only after reaching 'approved' status can a user create and publish an avatar. Regular founder accounts cannot create avatars.

#Four Example Avatar Personas
| Code | Persona | Primary Focus | Style |
|---|
| AV-01 | Seed specialist | EdTech, Pre-A | Weights market size and founder grit heavily. Asks 'who, why, and why now' |
| AV-02 | Series A specialist, SaaS | Global SaaS | Focused on global-expansion potential and English-market PMF metrics |
| AV-03 | B2B infrastructure investor | Cloud, DevTools | Digs deep into technical moats and data advantages — 'I'll even read the research papers' |
| AV-04 | Climate tech specialist | Climate, deep tech | Policy and regulatory timing plus a technology-maturity matrix |
You can browse the avatars currently live on the /avatar-agent page after signing up, and choose which avatar reviews your business plan.

#How to Use It
Showing your business plan to just one person is risky — any single perspective is biased. OpenSeed evaluates the same business plan simultaneously with system agents plus one or two avatars, giving you multi-perspective feedback.
- Before submitting a government pre-startup grant application -> use the government-program reviewer avatar plus the seed specialist (double verification)
- One week before a VC meeting -> run a pre-meeting simulation with an avatar styled after the investor you're actually about to meet
- While recruiting a co-founder -> check your technical differentiation with the technical-moat reviewer avatar

#How This Differs from Other AI Tools
| Category | Using ChatGPT or Claude Directly | OpenSeed Avatar |
|---|
| Prompt source | Written arbitrarily by the user | Input directly by a working VC or accelerator reviewer |
| Verification | None | Verified via proof of employment, accelerator registration, government ID, etc. |
| Consistency | A different answer every time | A fixed style per avatar (same tone for the same input) |
| Multi-perspective review | One perspective per session | 7 system agents + 1-2 avatars, run in parallel |
| Fund's accumulated experience | Cannot be reflected | Reflects the reviewer's own investment philosophy and red flags |
Summary.
#How to Register as a VC or Accelerator Reviewer
If you're a working reviewer at a VC, accelerator, PE firm, or government agency, simply select your category at sign-up and upload your verification materials. Once an admin reviews and approves you, you can build your own avatar at /avatar-agent/create.
After your avatar goes live, statistics accumulate every time a user gets reviewed by it — you can see, as data, which kinds of business plans your review style tends to respond well to, and which red flags come up most often.

OpenSeed's avatar agents aren't just another 'custom GPT' — they're reviewer simulations built on top of a verified network. The flow is sign-up -> category verification -> avatar creation. Founders, meanwhile, need no separate verification and can get reviewed by an avatar immediately.
