Draft a Proposal View pricing

AI proposals for startup founders means using Gixo to turn a pitch deck, product docs, and deal context into a structured written draft. Gixo supports 21 proposal types, reads sources via OCR intake, and exports to 6 formats, with shared team editing. It is source-first: each output reflects the specific pitch deck, market research, or RFI document you upload, while reviewers still validate the numbers, evidence, promises, and audience fit.

Consulting proposal: repairs satisfaction measurement, Harbourside Housing Association

A ten-week advisory engagement for an invented housing association: situation, approach and phases, a requirement-by-requirement compliance matrix, deliverables, timeline, team, terms, and a fee built phase by phase from the bidder's day rates, with the days of each role shown.

Inspect the source brief or data

Propose a ten-week advisory engagement for Harbourside Housing Association, on behalf of Larkfield Analytics Ltd, that answers the association's brief: review the current repairs survey, recommend how to measure repairs satisfaction by contractor, and leave a reporting approach for the repairs team and the board. Build the fee for each phase from the standard rates in the evidence file (the days of each role times the day rate) and show those days. Add nothing the evidence file does not state. Put a notice on the cover page that the buyer and the bidder are fictional and the proposal is a worked example. Inputs: the buyer's document (brief-harbourside-housing.md); the bidder's evidence file (larkfield-evidence.md); commercial terms: value 46,000 to 52,000 GBP, valid for 60 days, payment terms 'Invoiced monthly in arrears, payable within 30 days.'; deal context: The buyer and the bidder in this proposal are fictional, and this proposal is a worked example. The engagement lead presents to the buyer's board in the ninth week.

Read the sample review notes

A separate reviewer agent read its 177 claims against the bidder's evidence file, the buyer's brief and the deal terms: 115 are supported, 58 add design detail or an inference, 4 are in no input (it calls the fee fixed) and none contradicts one. Every price line recomputes. It is not a person's review.

Prepare the source pack

Choose the proposal kind and supply the buyer brief, approved evidence, delivery assumptions and commercial terms. For RFP work, retain the issued requirements and separate known answers from missing evidence.

Review the proposed response

Inspect scope, exclusions, requirements and price assumptions. Use reviewable edits and saved comparisons; an unresolved buyer question needs an owner or an explicit qualification.

Package the reviewed version

Inspect the actual PDF, Word or HTML output. Tracked delivery activity and a recorded deal outcome answer different questions; verify the recipient, permissions and current approval state before sharing.

Buyer requirements and response ownership

Keep buyer RFP files separate from bidder evidence and approved reusable answers. Inspect extraction coverage, requirement source locations, questionnaire previews and submission limits. Response work can carry an SME owner, due date, escalation owner and required reviewer decisions. Compare an addendum with the source before changing a response.

Commercial schedules and recurring totals

Review each line's quantity, rate, unit, optional status and one-off, monthly or annual recurrence. Inspect recurrence totals and the estimated first-year total separately. Currency, supplied tax input and commercial assumptions need review. When importing Business metrics, select and review the source values before applying them to the schedule.

Buyer edition and submission package

Choose the current saved response or an approved edition. Inspect retained attachments, filled questionnaires, the compliance matrix and the package preview. A release manifest identifies stored delivery bytes. For tracked links, review recipient access, expiry, password and permissions separately from delivery activity and the recorded opportunity outcome.

A draft or readiness check is not approval of pricing, legal terms or a delivery commitment. Arc proposal drafting does not imply CRM, CPQ or tax-calculation automation.

The first page of the RFP response Arc wrote: the cover details, the notice that the buyer and bidder are fictional, and the start of the executive summary.
What Arc wrote. A response to a council's request for proposals, written for an invented bidder: a cover letter, an executive summary, an answer to each of the ten mandatory and three desirable requirements, the team, two local-authority references, and a price built from the bidder's day rates and unit rates, with every line showing its days or units. A separate reviewer agent read its 150 claims against the bidder's evidence file, the council's RFP and the deal terms: 132 are supported, 16 go a little beyond an input, 2 are in no input (it calls the price fixed, and it cites a 1,950-word limit nobody set) and none contradicts one.

Why Do Startup Founders Use AI to Write Funding Proposals and Investor Updates?

Startups often need a clear proposal without a dedicated proposal team. Gixo turns existing materials into structured drafts so founders can spend their time validating the story, evidence, and ask.

Limited Resources, Professional Output

You do not have a bid team or a proposal writer. Upload your pitch deck, product documentation, or market research and Gixo generates a structured proposal draft with the sections a proposal conventionally carries, so you start from a shape rather than a blank page. Whether it wins depends on the offer and the price, not the formatting.

Structured Investor Draft

Investors and enterprise buyers expect clear, structured documents. Gixo can draft sections such as the executive summary, market opportunity, solution overview, financials, and ask; founders must validate the evidence and the claims before sharing.

Iterate Fast Across Audiences

Different investors and partners care about different things. Generate tailored proposals for each audience by uploading the relevant context — a VC wants market size and unit economics, an enterprise partner wants integration details and security posture.

What Proposal Types Can Gixo Generate for Startup Founders, and Who Are They For?

Gixo generates the right structure for each stage and audience.

Proposal TypeKey SectionsAudience
Funding ProposalProblem, solution, market opportunity, traction, team, financial projections, askInvestors
Partnership PitchStrategic alignment, integration plan, mutual value, co-marketing, termsPartners
Pilot ProgramObjectives, scope, success criteria, timeline, resource requirements, pricingEnterprise Buyers

How Does AI Proposal Generation Work for Founders?

1
Upload your materials

Drop in your pitch deck, product documentation, financial model, or market research. Gixo reads everything and extracts the relevant context for the proposal type you select.

2
Choose proposal type

Select funding proposal, partnership pitch, pilot program, or investor update. Each type generates the section structure and depth that audience expects.

3
Refine your narrative

Edit the draft in the collaborative editor. Use inline AI tools to strengthen your value proposition, adjust financial projections sections, or tailor the language for a specific investor or partner.

4
Review, export, and share

Check the narrative, traction, financial projections, ask, and commitments, then export to PDF or DOCX for founder review before sharing with investors or partners.

Frequently Asked Questions

Can I use my existing pitch deck as a source?
Yes. Upload your pitch deck as a PDF or DOCX. Gixo extracts the key information — problem, solution, market data, traction metrics, team — and generates a structured written proposal that expands on the deck's content with the depth that written proposals require.
Is this useful for pre-revenue startups?
Yes. Upload your product documentation, market research, and competitive analysis. Gixo generates proposals that emphasize market opportunity, product vision, and team strength. For pre-revenue companies, the AI focuses on the forward-looking narrative rather than historical metrics.
Can I customize proposals for different investors?
Generate a new proposal for each investor by uploading context specific to their focus area. A healthcare-focused VC gets a proposal emphasizing regulatory moat and clinical validation. A generalist fund gets broader market sizing and competitive positioning. Source-first means each output reflects the input.
What about enterprise pilot proposals?
Select the pilot program proposal type. Upload the prospect's requirements or RFI document along with your product documentation. Gixo generates a proposal with clear objectives, success criteria, timeline, and pricing — the structure enterprise procurement teams expect.
Can my co-founder collaborate on the proposal?
Yes. Share the proposal with your co-founder with edit access, or create it in a shared team, where you can also see who else has it open. Edits are not merged, so agree who works on which section at a time, for example the technical co-founder on the product architecture section, then the business co-founder on the market opportunity narrative. If two saves conflict, Gixo asks you to compare the versions and choose what to keep.
What is AI proposal software for startup founders?
It is software that drafts structured funding proposals, partnership pitches, pilot programs, and investor updates from materials such as a pitch deck, product documentation, or market research. Gixo reads those source documents through its supported intake paths and produces an editable draft; founders still verify the evidence, numbers, and commitments.
Can AI write a startup funding proposal from my pitch deck?
Yes, as a first draft. Upload your pitch deck as a PDF or DOCX and Gixo can extract the documented problem, solution, market data, traction metrics, and team information into a structured funding proposal. Verify every number, source, and investor-specific claim before sending it.
