# Esferaup — Reddit go-to-market subreddit map

**Context.** Esferaup is a pre-launch SaaS by Litus (Spain, May 2026). Pro surface targets directors of academias, escuelas y centros infantiles (deporte, música, idiomas, refuerzo, atención temprana, TEA). Parents surface is a companion app giving madres/padres a 360° developmental view across every centre the child attends. UI in castellano + català.

Reddit is small in Spain vs. the US, but `r/spain`, `r/es`, `r/catalunya` etc. have real activity. Most of the volume that matters for Esferaup is in **English-language vertical communities** (educators, coaches, parents of neurodiverse kids) where Spanish founders are welcome if posts are substantive. Most of these subs ban overt promo — runway posts, founder-voice answers, and weekly self-promo threads are the realistic surface, not paid placements.

Reddit hid public subscriber counts in 2026 (community-size buckets only), so most numbers below are best-effort from subredditstats / GummySearch / X mentions of recent counts. **Verify each before posting or budgeting ad spend.**

## A. Spain-specific subs

| Subreddit | Approx. subs | Fit | Angle | Self-promo / red flags |
|---|---|---|---|---|
| [r/spain](https://reddit.com/r/spain) | ~1.0M (verify) | Parents | EN-language sub about Spain. Founder-voice posts about RGPD, escuelas privadas, atención temprana waitlists land if framed as discussion not pitch. | No overt promo, strict mods, ban on referral / affiliate posts. Use it for thread participation, not launches. |
| [r/es](https://reddit.com/r/es) | ~200K (verify) | Both | Casual Spanish-language sub. News + life posts. Use for founder Q&A ("¿Cómo elegisteis academia para vuestros hijos?"). | No self-promo unless flagged; meta-posts about apps frequently removed. |
| [r/askspain](https://reddit.com/r/askspain) | ~100K (verify) | Parents | English-language Q&A about life in Spain. Expats with kids asking "best academy in Barcelona for English / chess / piano" is a recurring thread shape. | Comment-based participation only. Top-level promo will be removed. |
| [r/AskCatalonia](https://reddit.com/r/AskCatalonia) | ~5–10K (verify) | Parents | Smaller, expat-heavy. Catalunya-specific questions about extraescolars / casals. | Tiny community; one off-tone post burns reputation. Comment, don't post. |
| [r/Catalunya](https://reddit.com/r/Catalunya) | ~80K (verify) | Both | Català + castellà sub. Cultural and civic discussion. Founder posts in català about extraescolars + AMPA dynamics could land. | Heavy political content; avoid politicising the launch. No promo without prior karma. |
| [r/Madrid](https://reddit.com/r/Madrid) | ~150K (verify) | Parents | Madrid-area, mixed ES/EN. Recurring "where to enrol kid in X" threads. | Strict no-promo. Use for replies only. |
| [r/Barcelona](https://reddit.com/r/Barcelona) | ~200K (verify) | Parents | Highly expat-heavy. Parents in BCN cross-shop multiple academies — direct fit for Parents 360° narrative. | Mods aggressive on perceived ads. Comment in "best afterschool for…" threads. |
| [r/Valencia](https://reddit.com/r/Valencia) | ~30K (verify) | Parents | València-area sub, partially Valencian / castellà. Smaller but engaged. | No overt promo; community is close-knit. |
| [r/Sevilla](https://reddit.com/r/Sevilla) | ~15K (verify) | Parents | Andalusian capital sub, useful when Esferaup expands south. | Same as above. Founder voice or none. |
| [r/Bilbao](https://reddit.com/r/Bilbao) | ~15K (verify) | Parents | Basque-country sub; helpful if Esferaup ever adds euskera support. | Strict no-promo. |

## B. Spanish-language parenting subs

| Subreddit | Approx. subs | Fit | Angle | Self-promo / red flags |
|---|---|---|---|---|
| [r/Padres](https://reddit.com/r/Padres) | <5K (verify; mostly baseball "Padres") | Adjacent | Mostly San Diego Padres baseball — NOT useful, name collision. | Skip. |
| [r/crianza](https://reddit.com/r/crianza) | ~5K (verify) | Parents | Spanish-language parenting sub. Discussion of educación, escuelas, desarrollo. Founder-voice posts about pedagogy could land. | Tiny but the most authentic ES-parenting sub. Mods active; no promo. |
| [r/PadresEspanoles](https://reddit.com/r/PadresEspanoles) | <1K (verify; may not exist) | Parents | Likely too small to matter or non-existent — name spelling varies. Search alternates: r/PadresEspañoles, r/PadresES. | Verify existence before targeting. |
| [r/AskParents](https://reddit.com/r/AskParents) | ~80K (verify) | Parents | English-language Q&A sub; Spanish parents do post here. | Promo-prohibited. Comment-only. |

| [r/daddit](https://reddit.com/r/daddit) | ~1.6M | Parents | Lighter tone; dads sharing wins and tools. Slightly more tolerant of "I built this for my kid" framing. | Still no overt promo; founder dad voice in /r/SideProject crosspost works better. |

## Cross-cutting notes

**Reddit Ads in Spain.** Spain audience is reachable but small. Best targeting combinations for Esferaup:

- **Geo = Spain + interest = Parenting / Early Childhood Education / Soccer / Music / Languages.** Audience size is enough to spend €300–500/week meaningfully.
- **Subreddit-level targeting** is more efficient than interest-level for B2B (Pro surface). Target `r/Teachers`, `r/ECEProfessionals`, `r/MusicEd`, `r/TEFL`, `r/specialed`, `r/montessori` with Spain geo filter — small audience but laser-targeted.
- **Conversation Ads** (replying inside threads) work better than feed ads on niche subs.
- **Don't run carousel / video ads in neurodiversity subs** even if Reddit's targeting allows it. Reputational risk > marginal CAC.

**Posting runway / karma gates.**
- Most subs require **30-day account age + ~20 comment karma** before AutoMod releases your posts.
- Plan a 60-day pre-launch reading + commenting runway. One Litus / Esferaup-affiliated founder account, real name, with link to landing page in profile but not in posts.
- One promo per 60-day window per major sub (r/SaaS, r/SideProject) is the realistic cadence. Anything more = shadowban.

**Founder-voice template that lands across categories:** "I built [tool] because my [kid / partner / sister] runs an [academia/centro] and I watched her wrestle with [specific pain]. Here's what I learned about [pedagogy / RGPD / cross-centre coordination]. Curious how others have solved it." → no link, link in profile.

**Sensitivity around neurodiversity subs.** Treat r/Autism_Parenting, r/SpecialNeedsParenting, r/AutisticParents, r/ADHDparenting as **listening-only**. Esferaup processes RGPD special-category data; any whiff of marketing in those subs harms both brand and the people in those communities. If posting at all, post a one-time founder-voice question, no link, no ask, and follow the mods' DMs if any.

**Language strategy.** Most Spain-relevant subs are English-language. Post in English on r/spain / r/Barcelona / r/AskCatalonia and in català only on r/Catalunya / r/catala (where it's expected). r/es and r/crianza accept castellano.

**Parents app crosspost graph.** Once the Parents app launches, run a four-week sequence: r/SideProject (week 1) → r/AlphaAndBetaUsers (week 1) → r/Apps + r/androidapps (week 2) → r/ScienceBasedParenting reply-only (ongoing) → r/Parenting / r/toddlers reply-only (ongoing) → never on r/Mommit (rules forbid).

**Don't overweight Reddit.** For a Spain-only academia-CRM, AMPA Telegram groups, AEFr, AECA (atención temprana), and local school-director WhatsApp chains will dwarf Reddit for B2B. Reddit is best for **Parents-surface UA + founder-narrative seeding** rather than Pro-surface lead-gen.
