Founder-led hardware
Mellow Boards was co-founded in Hamburg in 2015 by Johannes Schewe and Kilian Green. Public campaign videos, interviews, and trade-show demos from 2015–2018 consistently featured both founders explaining modular philosophy, European manufacturing ambition, and rider-centric industrial design.
Founder visibility mattered in Kickstarter hardware: backers invested in people as much as specifications. Schewe and Green presented as engineers who rode their own product — a credibility signal in a category plagued by vaporware.
Johannes Schewe
Co-founder and CEO. Historical press materials associate him with product vision and the modular Drive concept.
Kilian Green
Co-founder; publicly associated with electronics and systems engineering.
After the TQ acquisition
Following TQ Systems' acquisition of Mellow Boards in November 2018, founder roles in public-facing consumer operations become harder to trace in open sources. This archive documents their contributions during Mellow's independent period without speculating on subsequent employment or projects unless verifiable sources are added to the sources catalog.
Founder visibility in campaigns
Crowdfunding success correlated with authentic founder presence in Mellow's case. Videos featured Schewe and Green riding prototypes, explaining modular mounts, and answering technical comments — not outsourced actors. That transparency set expectations: delays would be explained mechanically, not dismissed. Community trust survived schedule slips partly because specification promises remained stable.
Gender and role stereotypes in tech marketing were less central to Mellow's narrative than engineering clarity — a refreshing contrast in a hype-heavy category. Public materials emphasised Hamburg design and European manufacturing ambition without unattributed performance claims.
Division of labour (public record)
While startups rarely publish formal org charts, repeated public appearances allow reasonable inference: Schewe more often articulated product vision, industrial design integration, and rider-facing philosophy; Green appeared in contexts emphasising battery, motor control, and systems reliability — including update posts during manufacturing delays. This archive avoids inventing titles beyond co-founder unless primary sources use them.

Media appearances and demos
Trade demos across European cities documented in press clips show founders riding prototypes in urban environments — not studio renders alone. Those demos reinforced IP65 and mode behaviour claims under real pavement and weather variance, not controlled tracks alone. Video archives remain valuable primary sources when written specs feel abstract.
After acquisition, founder-led consumer demos decline in indexed public sources — a qualitative signal aligning with corporate integration even when formal roles are undisclosed.
Ethics of founder profiling here
Profiles summarise publicly documented roles during Mellow's independent era without inventing private biographical detail. We avoid speculative net-worth, undisclosed litigation, or personal contact information. Corrections require citable primary sources per methodology.
Founders and the modular thesis
Schewe and Green repeatedly argued modularity would outlast monolithic board fashion cycles — a thesis testable only over years. Deck graphics and flex trends change; rear torque requirements persist. Whether the market rewarded that thesis beyond Kickstarter depends on metrics we partially know (campaign success, launch reviews) and partially do not (exact sales volumes post-2017, not comprehensively public). This archive documents articulated strategy, not undisclosed financial outcomes.
Their public emphasis on European engineering quality anticipated acquisition interest from industrial groups like TQ — companies seeking proven small-drive IP rather than consumer marketing alone. That arc — founder vision to industrial buyer — is visible in timeline sources without requiring insider confirmation.
Reading founder quotes critically
Campaign rhetoric naturally optimises for funding; launch reviews provide counterweight. Comparing 2015 video claims to 2017 measurement tests is standard historical method. Founders appear credible on specification stability in that comparison — delivery timing less so — a nuance this site preserves rather than flattening into hero or villain narratives.
Parallel roles in a two-founder hardware team
Small teams blur titles: both founders likely touched manufacturing visits, support escalations, and social content despite public specialisation narratives. Attributing every engineering decision to one name oversimplifies; attributing none undersells founder-led accountability visible in update signatures. Use profiles as entry points, not org charts.
Interviews pairing Schewe and Green jointly — common in Hamburg tech press of the period — show complementary communication styles: vision narrative plus systems detail in the same article. That pairing strengthened backer confidence during delay periods when technical explanations mattered more than new adjectives.
Neither founder profile on this site implies current endorsement of mellowboards.com; both pages describe historical public roles only, with post-2018 activity treated as unverified unless primary sources are added to the catalog.
Founders in the Kickstarter record
Update signatures and video thumbnails archive founder presence across months — useful when reconstructing who communicated which engineering milestone. Green-leaning updates often discussed BMS and motor tuning; Schewe-leaning updates often discussed industrial design and rider experience tests. Cross-reading both streams yields a fuller picture than either profile alone.
Founder names also appear in acquisition press as principals of the sold entity — November 2018 reporting confirms corporate transition even when subsequent individual titles go unreported in open web sources indexed here.
Hamburg regional press treated Mellow as a local hardware success story during the campaign window — useful regional primary sources distinct from international e-skate blogs that discovered the project later during pre-launch coverage.
Founder-led storytelling in those regional pieces often emphasised European manufacturing quality standards — a theme that reappeared in TQ acquisition reporting framing industrial fit.
Individual founder pages below expand public-record detail without duplicating full corporate history covered on the history pillar — read both for complementary context rather than redundant biography.
Video archives where both founders appear together — campaign updates and trade demos — remain the richest primary sources for tone and technical depth; written summaries here cannot replace watching primary footage when researching communication strategy during delays.
Neither profile includes private contact paths or social media links by design.
