skills/sales-arrfounder/SKILL.md
Arrfounder platform help — founder revenue directory by @Folyd (2024) that auto-extracts MRR/ARR + products from Twitter/X bios via AI, lists 1000+ founders on sortable leaderboards (ARR / followers / products / recently added), free Airtable submission with 24-48h manual approval, auto-syncs within hours of bio changes. Social-proof verification only (no Stripe / Lemon Squeezy / Polar API integration) — built for peer discovery and community browsing, not acquisition-grade proof. Use when getting listed on Arrfounder, writing a Twitter/X bio that passes the MRR/ARR extractor, fixing a profile that didn't get approved or stopped updating after a bio edit, deciding Arrfounder vs TrustMRR or StartuPage for verified-revenue display, benchmarking against peers in the $1K-$10M+ ARR tiers, or using Arrfounder as a comp-check tool before pricing a sale or fundraise. Do NOT use for selling/buying a project or cross-marketplace valuation (use /sales-side-project-valuation).

If references/learnings.md exists, read it first for accumulated platform knowledge.
Ask the user:
What do you need help with?
Do you have an active Twitter/X presence with MRR/ARR in the bio already?
If the user's prompt already provides enough context, skip directly to the relevant step. Lead with your best-effort answer and ask only the most critical 1-2 clarifying questions.
If the request maps to another skill, route with an explicit command:
| User's problem | Route to |
|---|---|
| Selling a verified-revenue startup with API-level proof | /sales-trustmrr {user's question} |
| Full founder ecosystem with hiring / fundraising / co-founder / acquisition posts | /sales-startupage {user's question} |
| Picking which marketplace to list on for acquisition | /sales-side-project-valuation {user's question} |
| Listing on Acquire.com / Flippa / Empire Flippers | /sales-acquire, /sales-flippa, or /sales-side-project-valuation {user's question} |
| Growing Twitter/X audience (not the listing itself) | /sales-audience-growth {user's question} |
| Cross-directory launch for a product | /sales-launch-directory {user's question} |
Otherwise, answer from platform knowledge below.
Read references/platform-guide.md for the full platform reference — submission flow, Twitter/X bio format, leaderboard mechanics, revenue tiers, positioning vs TrustMRR / StartuPage / FounderMRR, monetization, and known gaps.

$10k MRR, 100k ARR), then product name(s) and URL(s), then a short product description. Arrfounder's AI extracts from the bio, so if revenue isn't explicit there, you won't rank correctly. Submit via the Airtable form; approval is 24-48h.If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there with today's date.
Best-effort from research — review these, especially items about submission criteria and monetization that may be outdated.
@Folyd on Twitter/X directly. Founders can be listed for free indefinitely — there's no paid tier to boost ranking./api and similar routes 404. Programmatic access requires scraping (against ToS) or direct contact.

Heavier-weight alternative to Arrfounder when you want a full profile + hiring / fundraising / co-founder / acquisition posts, not just a directory listing./sales-side-project-valuation — Side project valuation and marketplace selection.

npx skills add sales-skills/sales --skill sales-doUser says: "I run a $3K MRR SaaS, have 2K Twitter followers, want to get on Arrfounder. What do I do?" Skill does:
$3k MRR (or 36k ARR) string, product name, product URL, short descriptionBuilding Foo — $3k MRR SaaS that does X. foo.com. Also building Bar.User says: "I'm about to list my $1.5K MRR SaaS on Acquire.com. Can I use Arrfounder to sanity-check my asking price?" Skill does:
$10K-$100K ARR tier (your ~$18K ARR falls here) to browse 10-15 peer founders, note their product types and public growth stories/sales-side-project-valuation
Result: User gets a useful peer-research step, then hands off to the valuation skill for the actual price.User says: "I want a public 'verified revenue' page. Should I use Arrfounder or TrustMRR?" Skill does:
/sales-startupage if the user wants more than a directory entry.
Result: Clear trade-off framing with a concrete recommendation based on audience.Symptom: Listed on Arrfounder but ARR/MRR on profile is stale, wrong, or missing
Cause: Twitter/X bio changed, bio uses a format Arrfounder's AI doesn't pick up (e.g., "Making real money", "6 figures"), or the sync hasn't run yet
Solution: Open your Twitter/X bio and verify MRR or ARR appears as a distinct numeric string with $ and k/m and MRR/ARR (e.g., $5k MRR, $120k ARR, $2M ARR). Remove fuzzy phrases. Save the bio and wait a few hours for the next sync. If still wrong after 24h, re-submit via the Airtable form with a note about the update, or DM @Folyd on Twitter/X. No in-platform edit UI exists.
Symptom: Submitted via Airtable days ago, no confirmation email, profile doesn't appear
Cause: Usually one of: Twitter/X bio didn't have MRR/ARR in a parseable format, Twitter/X account looks inactive or low-quality, product URL doesn't resolve, submission failed the "real founder / real product" authenticity check
Solution: Update the Twitter/X bio first — put MRR/ARR near the top with a product URL that resolves to a real product page. Make sure the Twitter/X account has recent activity (tweets in the last 30 days). Re-submit via the Airtable form. If still nothing after another 48h, DM @Folyd on Twitter/X briefly noting the product and revenue — the team is small and a direct nudge is the only fast path.
Symptom: Want to build a dashboard, comparison tool, or automation using Arrfounder data
Cause: Arrfounder has no public API (as of April 2026) — only the public website
Solution: The site renders server-side so data is visible in HTML. Scraping is technically feasible but violates ToS — do not build on it for anything public. The legitimate paths are: (1) DM @Folyd to request data access, (2) use TrustMRR's public API (tmrr_* Bearer token, 20 req/min, documented endpoints) if you can work with their ~100+ startup subset instead, (3) use FounderMRR which pulls from TrustMRR. For peer-research use cases a one-off manual browse is usually enough.
