Co-founders — Technical, Product/Quant & Commercial

Solpace is an independent, Stockholm-born music technology startup supported by KTH Innovation. We exist to return financial power, direct fan ownership, and creative autonomy to the artists, clubs, and dancers who live the culture—replacing corporate streaming pennies, 30% store cuts, pay-to-reach social algorithms, and ticketing monopolies.

We give artists 0% commission with instant multi-party Smart Splits (even inside DJ sets), geographic tour routing, booking intelligence, and automated promo video & Meta/CRM campaigns—while equipping clubs and promoters with data-driven booking, automated campaign tools, and offline-resilient event infrastructure.

We are looking for a Commercial Co-founder & Head of Growth (GTM) to lead our Go-To-Market across clubs, promoters, and independent labels in Europe, shape our pricing and business model, and drive angel/VC fundraising alongside our founder (KTH IndEk Computer Engineering & ML, CS at SU).

What We Have Built So Far

• Core platform under active development in a clean TypeScript/Python monorepo (React, Next.js, React Native, Node.js/Express, Python/FastAPI, PostgreSQL/pgvector, SQLite, Redis, BullMQ, MeiliSearch, Stripe Connect, Docker, Caddy).

• Live public website with interactive B2B/B2C product demos and waitlist at solpace.org.

• Supported by KTH Innovation in Stockholm, with ongoing outreach across Stockholm and European electronic music scenes.

Track: Technical Co-founder — Systems, Audio AI & Live Infrastructure

• Profile: KTH Computer Science (Datateknik), Machine Learning (ML), Engineering Physics (TFYS), IndEk Data/ML, or an experienced fullstack/backend/ML builder in Stockholm.

• High-Concurrency Ticketing & Financial Integrity: Race-condition-free inventory locking under spike drops, BullMQ queues, idempotent webhooks, and Stripe Connect Smart Splits ledgers.

• Offline-Resilient Edge & Door Terminals: Local-first sync (React Native, SQLite) and 30-second rotating cryptographic QR verification in zero-signal basement clubs, scaling toward mesh & satellite fallback.

• Audio AI, Custom RecSys, Lucy & LLM Fine-Tuning: Open-weight LLM fine-tuning, custom PyTorch/TensorFlow/scikit-learn models, Lucy (zero-privilege AI concierge combining 0-token DSP heuristics with multimodal GenAI), Modal GPU pipelines (CLAP, OpenL3, YAMNet, librosa, CLIP, ffmpeg, pgvector), and sequential, deep ranking & graph RecSys models.

• Real-Time Community & Distribution: Clock-synced pre-release listening lounges, role-moderated event chat rooms, predictive demand pipelines, automated promo video rendering, and Meta Graph API / AI CRM workflows.

Track: Co-founder — Product, Quant & Business Architecture

• Profile: KTH Industrial Engineering & Management (IndEk — Applied Math, Product Development, or CS), Engineering Physics (Teknisk Fysik), or Applied Mathematics.

• Predictive Demand & Margin Engines: Spatial Yield Forecasting, automated ad-spend Net Margin risk guards, and ticket-velocity estimation for promoters.

• Marketplace Incentives, Routing & Pricing: Constrained tour routing optimization, 100% face-value waitlist clearing, friend-price referral rewards, Smart Splits economics, and B2B pricing tiers — Python (NumPy, SciPy, pandas, scikit-learn), SQL, TypeScript.

• Product & Decision Tools: Translating complex data, closed-loop attribution (listening -> ticket -> door/bar revenue), and payment flows into intuitive tools for organisers, venues, labels, and artists.

Track: Commercial Co-founder & Head of Growth (GTM)

• Profile: Stockholm School of Economics (SSE / Handels) or KTH Industrial Engineering & Management (IndEk), or an entrepreneurial B2B builder.

• Creator & Label Wedge: Onboard artists, DJs, and labels with 0% commission on music and DJ-set track sales, instant Smart Splits, fan-density tour routing, booking intelligence, and automated promo video & Meta/CRM tools.

• Venue & Organiser Arsenal: Bring our active web app and interactive demos into venue meetings (Yield Forecasting, margin-guarded campaigns, rotating QR tickets, offline door scanner, cashless bar POS, Slutna sällskap compliance) and co-shape workflows with pilot partners.

• GTM, Fundraising & Quant Crossover: Close pilot venues / organisers / artists, shape pricing and business models, leverage Nordic incubator tracks (such as KTH Innovation and SSE Business Lab), and lead Nordic angel/seed fundraising. Strong plus if you also bring analytical/quant fluency (unit economics, pricing scenarios, SQL/Python analytics).

What We Offer

• Substantial Co-founder Equity: True founding ownership in Solpace (equity-based founding role at pre-seed stage; no corporate bureaucracy).

• Flexible Transition: Works alongside studies, thesis, or current commitments, transitioning into full-time as we scale.

• Real Momentum from Day One: Interactive product demos, an active codebase, and KTH Innovation backing.
